Compact system and method for the production of liquefied natural gas

A facility for the production of liquefied natural gas comprising:

• an inside battery limit (ISBL) comprising a liquefaction train, wherein the liquefaction train comprises
• (a) a plurality of modules wherein each module being adapted to perform at least one process step associated with liquefied natural gas production, the plurality of modules comprising
• a first module for acid gas removal;
• a second module comprising a dehydration unit;
• a third module, being the liquefaction module;
• and
• a fourth module comprising equipment for processing of natural gas liquids.
• (b) a first mixed refrigerant cycle comprising a first mixed refrigerant and a second mixed refrigerant cycle comprising a second mixed refrigerant connected to the liquefaction module for cooling a gas stream to produce the liquefied natural gas;
• (c) a primary cooling loop to cool at least a process stream from each module and the first mixed refrigerant and the second mixed refrigerant against a first coolant comprising clean water, wherein the primary cooling loop is a closed clean water cooling loop and the cooling is against an ambient temperature;
• and
• (d) a first plurality of heat exchangers through which the primary cooling loop extends, wherein the cooling by the primary cooling loop is via heat exchange in at least the first plurality of heat exchangers with respect to the first coolant, wherein more than 50% of the first plurality of heat exchangers are printed circuit heat exchangers and wherein the printed circuit heat exchangers are adapted to provide at least 80% of the cooling against the ambient temperature.
