Engineering Process Design

To integrate risk assessment into the design process, engineers will likely need education and training on risk assessment in some form.

T he heart of a chemical process is a reaction in which several feed stocks are combined to make one or more products of greater value. Before the plant is designed, process engineers have to determine whether the reaction will proceed at a favorable rate, with sufficient conversion into the principal product to make the operation profitable. Once the optimum conditions for the conduct of the reaction have been established, the control system must be designed to maintain them. But there are many factors affecting the rate of the principal and side reactions, which must be appreciated before an intelligent design can be made. 

In order for flowsheets and P IDs to be understood by people with different job responsibilities such as plant designers, process engineers, instrumentation specialists, and vendors, it is useful to use standardized symbols and conventions on the flowsheets. Standards concerning instrumentation symbols and flowsheet conventions have been developed by technical societies, such as the International Society of Automation (ISA). However, individual companies often use different or additional symbols for particular processes.
