<p>A METHOD AND SYSTEM FOR THE SMALL-SCALE PRODUCTION OF LNG. THE METHOD COMPRISING: CONFIGURING A PRIME MOVER TO BE OPERABLE COMMUNICATION WITH A MULTI-STAGE COMPRESSOR; CONFIGURING THE PRIME MOVER TO BE IN FLUID COMMUNICATION WITH AN AMMONIA ABSORPTION CHILLER; CONFIGURING THE AMMONIA ABSORPTION CHILLER TO BE IN FLUID COMMUNICATION WITH THE MULTI-STAGE COMPRESSOR; OPERATING THE AMMONIA ABSORPTION CHILLER USING WASTE HEAT FROM A PRIME MOVER; PRE-COOLING A FIRST STREAM OF NATURAL GAS USING COOLED FLUID FROM THE AMMONIA ABSORPTION CHILLER; COOLING A FIRST PORTION OF THE FIRST STREAM OF NATURAL GAS, USING AN EXPANSION VALVE, INTO A TWO-PHASE STREAM; COOLING A SECOND PORTION OF THE FIRST STREAM TO LIQUEFIED NATURAL GAS, USING THE TWO-PHASE STREAM AS A COOLING FLUID; DELIVERING THE SECOND PORTION OF THE FIRST STREAM AS LNG TO A LOW-PRESSURE LNG TANK; COOLING A THIRD PORTION OF THE FIRST STREAM OF NATURAL GAS IN A TURBO-EXPANDER; SEPARATING LIQUID HEAVIES OUT OF THE THIRD PORTION OF THE FIRST STREAM OF NATURAL GAS; AND DELIVERING THE LIQUID HEAVIES TO A PRESSURE TANK.</p> |
