摘要:
A process and a device for separating hydrogen from a gas flow having an oxygen constituent, comprised primarily of hydrogen, nitrogen, oxygen, carbon dioxide, carbon monoxide, methane and/or other hydrocarbons, is disclosed. The gas flow is compressed in a multi-stage compression process and then cooled to room temperature by a heat exchanger. After a pre-adsorber, the gas flow is fed to a catalytic process for removing the oxygen. The catalytic reaction for removing the oxygen takes place exothermically. The gas flow is then cooled to room temperature via another heat exchanger and fed to a pressure swing adsorption process for hydrogen separation. The hydrogen is separated there from the residual gas.
摘要:
The process of the present invention provides high recovery and low capital cost giving it an economic advantage over previously known purification processes. The present process has particular applicability to the purification of synthesis gases comprising at least hydrogen (H2), carbon monoxide (CO), methane (CH4), CO2, and H2O to obtain a gas stream including at least H2, CO, and CH4, that is substantially free of H2O and CO2. The process also has applicability to the purification of natural gases inclusive of at least CH4, N2, CO2, and H2O to produce a gas stream including at least CH4 and N2, but which is substantially free of H2O and CO2.

摘要:
A process for separating hydrogen from a gas flow having an oxygen constituent and including predominantly hydrogen, nitrogen, oxygen, carbon dioxide, carbon monoxide, methane and/or other hydrocarbons, as well as a device for conducting the process, is disclosed. The gas flow undergoes a process to thermally convert oxygen prior to the pressure swing adsorption process.
摘要:
In a TSA process of an at least two-component raw gas, to adjust for fluctuation in load, the cycle time of at least one method step is extended in the event of falling below the design load value.
摘要:
The present invention is directed to a method and system of purifying hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption. The adsorbed impurities can be removed from the adsorbent by increasing the temperature, reducing the pressure, or a combination of both.
