The present techniques are directed to a multiphase separation system. The system includes a liquid-liquid separator configured to receive a separated liquid that is further separated into a separated oil and a separated water within the liquid-liquid separator. An oil pump and a water pump, both with adjustable speeds, are configured to pump the separated oil and the separated water, respectively, from the liquid-liquid separator. An interface level in the liquid-liquid separator is regulated by adjusting the speed of the oil pump and the speed of the water pump.

Multiphase separation system

Described herein are systems and processes to produce liquefied natural gas (LNG) using liquefied nitrogen (LIN) as the refrigerant. Greenhouse gas contaminants are removed from the LIN using a greenhouse gas removal unit. The LNG is compressed prior to being cooled by the LIN.

Increasing efficiency in an LNG production system by pre-cooling a natural gas feed stream

Described herein are systems and processes to produce liquefied nitrogen (LIN) using liquefied natural gas (LNG) as the refrigerant. The LIN may be produced by indirect heat exchange of at least one nitrogen gas stream with at least two LNG streams within at least one heat exchanger where the LNG streams are at different pressures.
