Mobile gas processing plant

A mobile gas processing transport, comprising:

• a base frame;
• an inlet and an outlet;
• a first Joule-Thompson (JT) valve unit, and a second JT valve unit, wherein each of the first and second JT valve units includes a first JT valve and a second JT valve, and wherein in an operational mode, and for each of the first and second JT valve units, a hydrocarbon gas stream flows through one of the first and second JT valves operating as a primary valve and does not flow through the other of the first and second JT valves operating as a backup valve;
• an actuator for the first JT valve unit;
• a control unit that is configured to control the actuator to shut the first JT valve of the first JT valve unit and switch the hydrocarbon gas stream to flow through the second valve of the first JT valve unit in response to detecting a failure condition;
• an inlet scrubber;
• a dehydration unit including a contact tower;
• an inlet filter separator and an outlet filter separator;
• and
• a vertical separator;
• wherein the first and second JT valve units, the actuator, the inlet scrubber, the dehydration unit, the inlet and outlet filter separators, and the vertical separator, are mounted on the base frame of the mobile gas processing transport.
