abstract

Large bore, spark ignited, reciprocating, gas engines have been the workhorse of the pipeline industry for many years when it comes to transmission of gas. Recently, the US government has released an update to the NSPS and RICE NESHAP regulating emissions from many of these engines to [1]:

Display Formula1gbhp·hgbhp-hrNOX

Display Formula2gbhp·hCO

Display Formula0.7gbhp·hVOCs (Non-methane, non-ethane hydrocarbons)

This new rule leaves many of these legacy engines out of compliance with the standard. Because of this, engine operators are left with the choice of decommissioning these engines as they come due for compliance based retrofit or working with engine OEMs to implement an emissions reduction strategy.

For many years, the traditional methods and tools used for engine design were more than enough to create a successful engine. But with tightening restrictions and higher expectations for customers and the amount of improvement that can be extracted from design changes shrinking with every redesign, these methods by themselves are no longer sufficient. This paper will examine modern design methods and tools available to an engine designer as well as their integration with more traditional testing methods. A comparison of results for the redesigned COOPER BESSEMER® GMVH-6C3 will also be presented for analysis.
