Engineering process development

Project plans and a dedicated project manager are required to coordinate across-site support activities, e.g. project planning, engineering, process development, production, QC (quality control), etc. This is critically important if production scale equipment and operating areas need to be used during the transfer exercise, i.e. the impact on commercial manufacturing schedules.

The IL can be recycled by a novel salting-out step or by common cation exchange, both of which save energy compared to recycling by distillation. Professor Rogers s current research is aimed at improved, more efficient, and economical syntheses of this particular IL, and studies of its toxicology, engineering process development, and commercialization.

The chemical industry represents a 455-billion-dollar-a-year business, with products ranging from cosmetics, to fuel products, to plastics, to pharmaceuticals, health care products, food additives, and many others. It is diverse and dynamic, with market sectors rapidly expanding, and in turmoil in many parts of the world. Across these varied industry sectors, basic unit operations and equipment are applied on a daily basis, and indeed although there have been major technological innovations to processes, many pieces of equipment are based upon a foundation of engineering principles developed more than 50 years ago. 

Process engineer usually the chemical engineer who developed the flowsheet. 

On the other hand, Mary, a research process development engineer, does not consider Joe s system to be inherently safer, because a truly inherently safer system would not require an interlock at all. The process uses flammable materials and operates at elevated pressure. Mary, looking at the entire process, would only consider it to be inherently safer if the flammable materials were eliminated or the process was operated at ambient pressure. Mary is considering the inherent safety characteristics of the entire process, rather than a single interlock system.

In this study detailed fault trees with probability and failure rate calculations were generated for the events (1) Fatality due to Explosion, Fire, Toxic Release or Asphyxiation at the Process Development Unit (PDU) Coal Gasification Process and (2) Loss of Availability of the PDU. The fault trees for the PDU were synthesized by Design Sciences, Inc., and then subjected to multiple reviews by Combustion Engineering. The steps involved in hazard identification and evaluation, fault tree generation, probability assessment, and design alteration are presented in the main body of this report. The fault trees, cut sets, failure rate data and unavailability calculations are included as attachments to this report. Although both safety and reliability trees have been constructed for the PDU, the verification and analysis of these trees were not completed as a result of the curtailment of the demonstration plant project. Certain items not completed for the PDU risk and reliability assessment are listed.

The process engineer also develops tests and interprets data and information from the research pilot plant. He aids in scaling-up the research qpe flow cycle to one of commercial feasibility. 

From the basic process-containing flowsheet other engineering specialties develop their own details. For example, the instrument engineer often takes the requirements of the process and prepares a completely detailed flowsheet which defines every action of the instruments, control valves, switches, alarm horns, signal lights, etc. This is his detailed working tool.

In general, for all real processes, there is a net production of entropy and Equation 2-113 applies. Since many practical engineering processes involve open systems, it is useful to develop a generalized expression of the second law applied to such systems.
