The single mixed refrigerant process was used widely in small and medium sized natural gas liquefaction plants. The single mixed refrigerant processes were simulated in changing of ambient temperature, mass flow rate and gas composition. Based on the project equipment, the process parameters subjected to be regulating were discussed. The result shows that by adjusting the refrigerant compressor operating pressure, refrigerant flow rate and composition, the single mixed refrigerant process can be well adaptable to the change of ambient temperature, gas flow and composition. The adjusted single-stage mixed refrigerant liquefaction process can keep the high refrigeration efficiency.
