Method and apparatus for regulatory control of production and temperature in a mixed refrigerant liquefied natural gas facility

摘要

Method to control production of liquified natural gas (LNG) outlet stream by refrigeration of the natural gas flowing through the process comprises: a) measuring temperature and flow rate of the LNG outlet stream b) varying the refrigeration of the natural gas to adjust temperature value of the LNG outlet stream and independently adjusting flow rate of LNG through process, to maintain the flow rate of the LNG outlet at a predetermined flow value and the temperature at a predetermined temperature value. Also claimed is an appts. for controlling production of liquefied natural gas by refrigeration.
