Contemporary Design Development and Stage Parameter Optimization Possibilities of Reciprocating Compressors for Refinery Application.

The article deals with some improper performance reasons of reciprocating compressors which are in yearround operation. The possibilities and recommendations for design optimization of some details and components and compressor operating parameters under existing industry conditions by means of the upgraded volumetric machine calculation program KOMDET-M designed for analyzing processes occurring in volumetric machines are represented. The calculation result agreement with parameters claimed by vendor and actual ones of gas reciprocating compressors which are in operation is shown. The scientific and practical value of the research for any designed, upgradable or operating unit is demonstrated. Necessary calculations have been performed by means of the application calculation program. Some examples of volumetric machine reliability and efficiency improvement are represented.
