Design Challenges for Reciprocating Compressors in Specialty Gas Services
نویسنده
چکیده
Many software tools are used to simulate compressor performance and pressure pulsations in piping systems. Designers of reciprocating equipment rely on these tools to accurately simulate gas properties and pressure pulsations for specialty gases. Two case studies on reciprocating compressors, involving ethane and ethylene, outline the root causes and consequences of inaccurate performance and pulsation predictions. Both systems experienced many problems after commissioning. Field analysis and subsequent simulation found inaccuracies in compressor performance modeling. This paper outlines a number of design tips and “lessons learned” that will be helpful to engineers involved in all reciprocating compressor applications. http://www.BetaMachinery.com
