An Overview of International Electrical and Safety Codes and Standards Governing the Application of Turbomachinery in Hazardous Areas

A plethora of codes, standards, and guidelines exist throughout the world offering a significant amount of input for the design engineer as he attempts to safely apply hydrocarbon processing equipment to hazardous areas. Fire suppression standards generated in and applicable to use in North America are also used throughout Europe. Off shore techniques are more stringent and must be carefully followed to protect the owner’s investment and for the safety of the equipment operators.This paper is a digest of all internationally recognized codes issued through commonly employed authorities extracting the peculiarities from each and building upon some basic premises to form a design specification that can be modified to suit the specific application or individual company policies.The discussion will be limited to enclosed and unenclosed gas turbine drivers and hydrocarbon gas processing compressors. Indoor and out door installations of this type equipment will also be considered.Copyright

Transient Control of an Expander Driven Generator in an FCCU Application

Successfully modeling an expander driven generator for a power recovery process is absolutely essential to satisfy the high reliability requirement of three years continuous operation demanded by users. The model, simulation and resultant control system design discussed considers the pressure control requirements of upstream separators, process piping configurations, performance characteristics of the rotating equipment, process valve design and finally process controller algorithms. Several examples of process simulation studies performed will be presented.Copyright
