  • Publication number: 20240100470
    Abstract: Present disclosure discloses a system for separating hydrogen from feed gas. The system includes at least one compressor adapted to pressurize the feed gas to predefined pressure. One or more adsorber columns are fluidly coupled to the compressor and are adapted to receive the pressurized feed gas, where the adsorber columns include a body and an adsorber bed, which is disposed within the body. The adsorber bed is configured to separate hydrogen from the feed gas. Further, the one or more adsorber columns includes a plurality of channels defined in at least one of the adsorber bed and adjacently along a length of the adsorber bed, where the channels are configured to channelize the hydrogen and regulate temperature of the adsorber bed. The configuration of the system aids in extracting pure hydrogen at low feed gas pressure.

  • Patent number: 9181901
    Abstract: Disclosed herein is a class of gas carburettor (9) for low calorific value gas for A/F ratio control to be used engines operating on producer gas with a load following capabilities. The gas carburettor has A/F ratio from 1.2:1 for producer gas to about 5:1 for biogas. The gas carburettor of the present invention has right A/F control at varying load conditions due to its optimized dimensions at the throat (7) and area ration control flapper (6) along with the zero pressure regulators. Additionally, using a by-pass facility starting the engine is established. By the use of a zero pressure regulator on the gas line, the gas pressure in the air and gas lines are maintained nearly the same downstream of the carburettor which helps in managing the appropriate air-to-fuel ratio based on the gas and air passage areas.
