Systems and processes for stationary and mobile natural gas liquefaction

A mobile natural gas liquefaction system comprising:

• one or more first mobile unit housing gas liquefaction equipment and a refrigeration system comprising primary, secondary, and tertiary refrigeration streams;
• one or more second mobile unit housing gas cleanup equipment;
• and
• one or more third mobile unit housing electrical power equipment;
• wherein the one or more second mobile unit is capable of fluid communication with the one or more first mobile unit in a manner to provide an incoming gas stream for the one or more first mobile unit and optionally capable of fluid communication with the one or more third mobile unit which allows transfer of gas supply thereto and wherein the one or more first mobile unit is capable of fluid communication with the one or more third mobile unit which allows transfer of fuel gas from the one or more first mobile unit to the one or more third mobile unit;
• wherein the one or more first mobile unit is configured to deliver the incoming gas stream to a single compressor inlet chosen from one of multiple compressor inlets depending on the pressure of the incoming gas stream;
• wherein the multiple compressor inlets comprise:
• at least one first compressor inlet configured to receive the incoming gas stream at a first inlet pressure and configured to receive the primary refrigeration stream;
• at least one second gas input compressor inlet configured to receive the incoming gas stream at a second inlet pressure that is different from the first inlet pressure and configured to receive the secondary refrigeration stream;
• at least one third compressor inlet configured to receive the incoming gas stream at a third inlet pressure that is different from the second inlet pressure and configured to receive the tertiary refrigeration stream;
• and
• at least one fourth compressor inlet configured to receive the incoming gas stream at a fourth inlet pressure that is different from the third inlet pressure and configured to receive the primary refrigeration stream, the secondary refrigeration stream and the tertiary refrigeration stream;
• wherein the one or more first mobile unit comprises one or more compressors in a flowpath downstream of the at least one first and second compressor inlets and one or more heat exchanger in the flowpath downstream of the one or more compressors;
• and
• wherein the one or more first mobile unit comprises an output for delivering liquefied natural gas to cryogenic liquid storage.
