Research of mixed refrigerant cycle for liquefaction of natural gas depending on ambient conditions and its regulation.

Number: pap. n. 980

Author(s) : KROSTOV A., KOLESNIKOV A., SAMOKHVALOV Y., et al.

Summary

Ambient temperature has sensible influence on parameters of single mixed refrigerant cycle for liquefaction of natural gas: decreasing natural gas inlet temperature and mixed refrigerant temperature in aftercooler in wintertime. System adjusting to ambient conditions can decrease annualized energy consumption. Authors develop simulation model and determine optimal operation parameters depending on ambient temperature. Test installation and procedure to verify model-made data are described. Control operation modes depending on ambient conditions are suggested. Obtained results can be applied at LNG (liquefied natural gas) plants, which are based on single mixed refrigerant cycle with phase separator.
