    Abstract: A process and a plant for obtaining highly pure methane from biogas where biogas coming from a fermenter is compressed and fed to at least one membrane unit having a selectively permeable membrane, which provides a product gas stream containing an elevated proportion of methane and a gas stream containing a reduced proportion of methane. A quality sensor may be arranged in the outlet line for the highly pure product gas. A vacuum pump, the capacity of which can be regulated, may be connected to the low-pressure side of one of the membrane units. It is controlled by a control unit which receives its input signal from the quality sensor in the outlet line, and if the proportion of methane measured by the quality sensor falls below a certain value, the capacity of the vacuum pump is regulated so that the pressure difference at the membrane increases.

  • Publication number: 20140224118
    Abstract: A method of pretreating a natural gas stream for a floating liquefied natural gas plant is described. A natural gas feed stream is introduced into an amine absorption unit and a temperature swing adsorption unit located on a ship. The temperature swing adsorption unit has a dehydration cycle and a CO2 removal cycle. The amount of motion of the ship, or the level of CO2 in the natural gas feed stream with reduced contaminants, or both, is monitored. If the amount of motion of the ship or the level of CO2 in the natural gas feed stream with reduced contaminants exceeds a predetermined value, temperature swing adsorption unit is switched from the dehydration cycle to the CO2 removal cycle.

  • Patent number: 8794237
    Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may include one or more flow restrictors to allow controlled release of oxygen enriched gas between the canisters.

The interior vent includes a vent wall having a top portion attached to the interior surface of the exhaust stack along the entire inner perimeter of the exhaust stack and a lower portion that extends downward into the exhaust stack to form an annular space or gap between the vent wall and the interior surface of the exhaust stack, and at least one opening in the interior surface of the exhaust stack between the top and bottom portions of the vent wall. The blower creates a tangential flow of the exhaust gas with sufficient centrifugal force to concentrate substantially all of the HMW gases along the inner surface of the exhaust stack. A transfer pipe removes the HMW gases from the interior vent.
