A split mixed refrigerant ('MR') natural gas liquefication system, where low-pressure ('LP') and medium pressure (&#x201c;MP&#x201d;) MR compressors are driven by a first gas turbine and a propane compressor and a high-pressure (&#x201c;HP&#x201d;) MR compressor is driven by a second gas turbine, is disclosed. The split MR liquefication system is configured to adjust the characteristics of the HP MR compressor to require less power when less power is available and more power when more power is available compared to the system's design point. Such adjustments allow for shifting the balance of power between the propane compressor and the HP MR compressor to improve LNG production efficiency.

Balancing power in split mixed refrigerant liquefaction system

A process for separating a first gas, for example CO, from a feed gas mixture comprising the first gas and a second gas, for example H, in five or more adsorption beds each containing an adsorbent selective for the first gas. The process comprises subjecting each of the adsorption beds to a repetitive cycle comprising, in sequence, (a) a feed step, (b) a rinse step, (c) a pressure decreasing equalization step, (d) a blowdown step, (e) an evacuation step, (f) a pressure increasing equalization step, and (g) a repressurization step. The feed gas mixture may be a reformate from a steam-hydrocarbon reforming process.
