In gas compressor applications, separating equipment is placed upstream of compressor stages to remove water and hydrocarbon condensates. However, field experience indicates that liquids can still be carried over. Furthermore, pressure and heat losses in compressor pulsation bottles and nozzles may be sufficient to condense liquids. An ongoing project sponsored by the GMRC is investigating wet gas formation and carryover within compressor pulsation bottles. In this presentation, the 3-D models used to investigate this phenomenon are described. Results of several model simulations are discussed. Recommendations are given to help identify which compressors are susceptible to problems with wet gas.
