A single compressor is used to separately compress permeate from cascaded first and second gas separation membrane-based separation units and residue from a fourth gas separation membrane-based separation unit in order to avoid too high a CO2 partial pressure in the compressed permeate. After the permeates from the first and second stages are compressed, the compressed stream is fed to a third gas separation membrane-based separation unit.

Integrated compression and membrane separation process for removal of CO2 from raw natural gas

In a method for compressing a gas that is to be separated in a low-temperature COseparation unit using at least one partial condensation step and/or at least one distillation step, the gas that is to be separated has a variable composition and/or variable flow rate, the gas that is to be separated is compressed in a compressor to produce a compressed gas and the inlet pressure of the gas that is to be separated, entering the compressor, is modified according to the COcontent and/or the flow rate of the gas that is to be separated so as to reduce the variations in volumetric flow rate of the gas that is to be separated entering the compressor.

Compression method and apparatus for an apparatus for capturing COby low-temperature separation

A method and apparatus for compressing a gas flowing comprising at least 0.1 vol % water, include a compressor containing N compression stages, in which each compression stage includes a compressing means and an exchanger directly or indirectly connected to a water-coolant circuit; and in which at least a first exchanger and a second exchanger, in first and second consecutive or non-consecutive compression stages, are connected in series to the water-coolant circuit. The exchangers, which are not connected in series to the water-coolant circuit, include at their water-coolant output a pressure drop device.
