Production of Liquefied Natural Gas (LNG) in cryogenic natural gas processing plants

摘要

Comprising: (a) to cool The Flow of Natural Gas to condense at least a portion of the same current and form a condensate; b) Separating a Stream distillation Plant, to provide some of the cooling required to condense The Natural Gas Stream; (c) SEPAR AR a first portion of the flow of condensate, taking it to an intermediate pressure,And use it to provide some of the cooling required to condense The Natural Gas Stream, and then lead to the Plant; and (d) to expand at low pressure, the remaining portion of the flow of condensate to form the flow of Liquefied Natural Gas.The Apparatus to liquefy The Natural Gas Stream includes: i) a First current shunt connected to the floor; (ii) means of Heat Exchange (i) connected to receive the flow of Natural Gas; (iii) a Second means of current shunt connected to the floor,And connected to (ii); (iv) a Third means of shunt connected to (ii), (V) connected to a First expansion; and (iv), (VI) connected to a Second Medium expansion (ii)
