Dividing Wall Column Technology Advances
Although dividing wall column (DWC) is a proven technology and fairly well established in practice, and highly appealing regarding energy and capital saving potential, the number of industrial applications is still limited. As elaborated in greater details elsewhere, e.g. Jansen et al., Chemical Engineering, August 2014, 40-48, a DWC is an atypical distillation column and there are certain process and mechanical design and operation-related concerns and potential constraints that may discourage inexperienced practitioners and make them reluctant to consider design and implementation of a DWC in prospective applications.
Indeed, a reliable hydraulic design method is needed to translate performance simulation results into diameter(s) and height of the shell of a new DWC, or to examine appropriateness of an existing column shell in a retrofit case. Internal layout and dimensions of normal and partitioned sections depend on chosen type and size of structured packing and auxiliary equipment. Related calculations must be done with certain rigor if one wishes to arrive at a reliable basis for evaluation of cost-effectiveness of both new DWC designs and retrofits. The present paper aims at filling the existing know-how gap, and addresses all relevant aspects of packed DWC design using engineering tools available in public domain. In cases where screening experiments have to be made, mini-plant and pilot scale equipment solutions are available.
Distillation – an old dog can learn new tricks!
Distillation has come a long way since the ancient Egyptian and Greek alchemists, and new advances are still being made. This presentation will focus on recent improvements to the distillation process including divided wall column (DWC) configurations and new higher efficiency distillation tray devices that will help to minimize energy consumption and capital investment in future refineries and chemical plants. Industrial examples will be shown from the refining and petrochemical industries.
FRI test results and industrial applications for new high capacity Raschig Mini Fixed Valve

Filtration Testing for Reliable Process Performance
Whether new or used filtration equipment is considered for process expansion or R&D scale up, there are numerous considerations that should be investigated to ensure that pilot plant or commercial plant scale up is successful. In order to make these expansions reliable, consider testing the suspension(s) as a part of a systematic approach to determine the filtration process window.
Variations in solids concentrations can be the most underrated variation in determining what technologies can be best utilized. Part of the utilization determination should also take into account both capital and operating cost as well as various “environmental” issues such as personal protection
BHS Continuous Pressure & Vacuum Filtration Technologies
This presentation will discuss lab testing, pilot testing and scale-up for converting chemical processes to continuous filtration technologies from batch filtration operations. The overall scheme can be used by process engineers to develop optimum continuous pressure or vacuum filtration solutions for high-solids slurry applications.
In this first process a liquifed gas slurry is used to produce a specialty chemical. A liquefied gas is a clean, colorless gas that is easy to liquefy and transport. It is gaseous at normal temperature and pressure, but changes to a liquid when subjected to modest pressure or cooling. The most important point is to keep these gases, under pressure, so they behave as a liquid during filtration, cake washing and drying. The presentation discusses the process testing in the laboratory and in the field to evaluate continuous pressure filtration as an alternative to batch pressure filtration.
In this second process, the objective is to replace the current batch centrifuge with a technology that would be suitable for conversion to a continuous process. The initial lab tests suggested a vacuum belt filter would achieve cake quality equal to or better than the current centrifuge with a major reduction in processing time. The decision, after the lab testing, was to select a vacuum belt filter for pilot testing.
The presentation includes technology descriptions, discussion of specifications and general guidelines for performance guarantees.
SIHIboost -Efficiency gains with a new type vacuum booster pump
Increasing pump capacity with a need for better vacuum levels has, historically, required rotary lobe blowers ahead of a conventional backing pump. The combination, although effective, is encumbered by restrictions to compression ratio and is, therefore, oHen used in a multiIstage, “stacked” arrangement; ahead of conventional oil sealed or liquid ring backing pumps. The inherent inefficiencies of the rotary lobe blower lends to high energy use with a heavy footprint within the production environment. SIHIboost vastly improve efficiencies with minimal footprint. The new design boasts high speed spindles to achieve deep vacuum and eliminates the need for a “stacked” blower configuration. A high compression ratio capability reduces the backing pump requirement to 1/10th that of a pump used within a rotary lobe blower system. Significant energy savings, reduced maintenance and lower “up front’ investment make SIHIboost a sound decision for optimized return on investment.
Computer Modeling of Large and Distributed Vacuum Systems
As the size and complexity of vacuum systems increases the financial and technical challenges of them do so also. Accurate modeling allows system optimization in advance of engineering efforts and potentially negates the need for inefficient and costly empirical iterations. This paper describes a unique computational modeling technique for vacuum systems which incorporate any number of primary and secondary pumps and other pertinent elements. Examples are shown to illustrate the accuracy and efficacy of the technique.

Safety Instrumented System Design: Key Decisions to Avoid Regret Costs
This presentation discusses critical decisions and activities that take place during the Front-end Loading phase of Safety Instrumented System (SIS) design in accordance with ISA84/IEC61511. These decisions, when made correctly, present an opportunity to improve the longer-term viability of achieving the intended risk reduction, reduce the costs of late-stage design changes, construction, and SIF maintenance. We will discuss the importance of these critical items, their impact on system design, engineering, construction, and maintenance costs, as well as strategies for addressing these items when limited information is available. Examples of critical decisions will be discussed, that span from the processing of the Risk Assessment output to testing philosophies.
Reducing Human Error from Your Safety Instrumented System (SIS) to Achieve ISA 84 Compliance
A Safety Instrumented System (SIS) is designed to reduce the likelihood of hazardous risk by decreasing the frequency of unwanted accidents. The amount of risk reduction that an SIS can provide is represented by its safety integrity level (SIL). The SIS is designed to detect when the process reaches a hazardous condition and respond accordingly to move the process to a safe, thus preventing the unwanted accident from occurring. Studies indicate however, that over 50% of all SIS failures are related to human error. While many SIS systems boast having SIL 3 certification, it’s often the human interactions that render many of these well intended systems to be essentially non-existent. A safety interlock matrix is a proven tool that will help reduce the human errors throughout the entire safety lifecycle of the SIS.

Metasys Enterprise Optimization (MEO)
Improved Reliability Using Wear-Resistant Ceramic Coatings
Pivotal to the success of reliability and predictability in industrial equipment, ceramic based polymer composites can be used to increase efficiency and reduce down-time in aggressive industrial applications. Preventive and scheduled maintenance maximize the life and structural integrity of large and small metal components such as mixing vessels, pumps, hoppers, housings, tanks, chutes, pipes, and centrifuges where these heavy-duty parts are often exposed to aggressive slurries, sand aggregates, particulates, and large stones that can cause damage and abrade even the hardest reinforced steel substrates.
Ceramic based polymer composites help to protect industrial equipment in aggressive environments from mechanical and chemical attack, helping to maintain efficiency and reduce unexpected failures. Technologies in the ceramic based polymer composite products have consistencies ranging from ultra-smooth and high gloss to large beaded compounds. The coatings can be applied to a wide variety of geometries by troweling, pouring, brushing, or spraying.

Modeling, Simulation & Information Lifecycle Management
Improving Speed to Market with Flowsheet Simulation and Modeling Tools
Flowsheet simulation is a key technical tool for modeling industrial processes and improving speed to market. Understanding the key process variables and interactions of an industrial process allow proper equipment design and integration with existing facilities. Correlations and base models developed during the R&D phase can be easily integrated into the flowsheet model which improves technology transfer and maximizes the value of your intellectual property.
Many different process configurations can be easily tested to match the new process to existing facilities. Overall investment can be estimated by identifying additional equipment needed, or expanded capabilities of existing equipment and services. Energy minimization, and heat integration are modeled in the simulation to maximize the efficiency of the process.
Project timelines are streamlined by utilizing dynamic flowsheet simulation to validate detailed designs, test process control logic, and operator interfaces during the project construction phases. Operator training simulation (OTS) can be coupled with the dynamic model to pre-train operators of the new process. OTS pre-training will reduce necessary technical support during process startup, minimize operational errors, and reduce the startup timeline. Flowsheet simulation is often provided to the process operating personnel though simplified input interfaces, frequently built in Excel, to enhance their understanding of the process. Automated simulation models can also be tied directly to the process controls, and provide operators with process alerts, automated diagnose, and improved process performance.

Understanding the Nature of Odor for a More Effective Response
Odor is a sensory response to a compound or mixture of compounds. Although some classes of compounds are more odorous than others, the impact of odor on an individual or community can not be predicted on the basis of chemistry alone. To address issues related to adverse odor impacts leading to community complaints, one needs to understand the odor science and the methodologies for sampling, measuring, monitoring, and modeling of odor on the basis of sensory perception. This presentation will review the methodologies for characterizing odors to better define its impacts on the environment and optimize the capital investment required to mitigate its adverse effects.
Odor Control Using Unique Thermal Oxidizer
There are many options for reducing odors of which thermal oxidation is one. There are many thermal oxidizer designs used in industry, one of those is Flameless Thermal Oxidation (FTO). The major design characteristics for each type of Thermal Oxidizer are presented. The advantages of the FTO are explained. A selection chart to guide the engineer for all thermal oxidizers is presented.
Combustible Dust Protection in the Chemical Processing Industry
Combustible dust explosions are one of the most elusive and dangerous hazards at nearly all industrial facilities manufacturing or handling chemical products. There is no universal gas law for dust and as a result, every application is different and every material presents a different risk. The means of safeguarding against these hazards varies with each application and therefore each situation warrants its own risk analysis. In addition to the hazard themselves, the regulatory environment involving combustible dust is also complex and requires its own level of comprehension. The release of NFPA 652 in October of this year will undoubtedly change the landscape of how these hazards are dealt with.
Arc Flash Hazards and NFPA 70E
This presentation presents the hazards of Arc Flash and the requirements of the National Fire Protection Association’s (NFPA’s) Code 70E for the workplace. NFPA Code 70E provides inspection and testing procedures and practices for evaluating the safety of installed electrical systems in residential, commercial, and industrial facilities. It requires that employees be protected from electrical hazards such as arc flash. This presentation uses discussion and videos to show various aspects of what an arc flash is, how it can be started, what protection methods can be used, and how to potentially lower arc flash incident energies. It also outlines proper methods of compliance per guidance developed by the Institute of Electrical and Electronics Engineers (IEEE).
How to prepare operators for responding to emergencies
According to a recent ARC Advisory Group study, it was reported that operator error is the leading cause of significant plant incidents. In the process industries, these incidents account for the highest dollar loss per incident, resulting in 42% of unscheduled plant shutdowns. The process industry now faces the enormous challenge of replacing an aging workforce with a computer-savvy, gaming generation over the next five years.
It’s been shown that people learn best by doing, as opposed to lecture or demonstration. The airline industry for years has recognized the need for simulator training so that pilots can experience hazardous situations and learn from their mistakes while in a safe, virtual environment. Advances in computer speed as well as process simulation now allow rigorous, first-principal simulation models to be used for operator training.
With an Operator Training Simulator (OTS), operators can practice starting-up the unit and responding to emergencies, during which their every move can be measured against a benchmark for scoring. Instead of opening and closing real valves, their actions open and close virtual valves in the simulation model.
Outside operators can also be included via the use of a 3-D virtual reality environment, where they walk around in a true virtual world. This virtual world is linked with the same rigorous dynamic model, allowing for board and outside operators to coordinate like they do in the plant. Virtually all companies in the process industries are extremely lean, so options like training program development as well as cloud-based execution can be important to minimize the demands on management and IT as an OTS program is rolled out.

Project Certainty: Reduce cost, complexity and accommodate late-stage project changes
Due to project excesses, billions of dollars are lost annually in oil and gas exploration and production, hydrocarbon and gas processing, chemical, pharmaceutical, and other process industries. According to industry data, over 65 percent of projects greater than $1 billion fail, with companies exceeding their budgets by more than 25 percent or missing schedules by more than 50 percent. Routinely, they also face operational problems continuing through the second year of operations. This consistently poor project performance can be a serious deterrent to process manufacturers considering new investments. Emerson’s Project Certainty begins with early engagement during engineering and design studies to define project goals and high impact strategies to meet those goals. Despite traditionally accounting for approximately 4 percent of a project investment, automation is revealing unique and repeatable ways to eliminate cost, reduce complexity and accommodate late-stage project changes, beyond the automation discipline.
How Integrating Civil and Architectural Design Functions Will Save Your Schedule
The silo-ing of engineering disciplines has the unintended consequence of preempting use of time-saving approaches to acid proofing concrete structures. Civil engineers design industrial concrete structures then pass the designs to the architectural finishes team to specify protective linings, foregoing the use of approaches that offer faster turnaround time. This presentation will highlight polymer concrete and anchored thermoplastic lining technologies with unique construction time saving advantages dependent upon integration of civil and architectural design packages.
