摘要： A membrane-based process for separating mixtures of target gases if the gas mixture also contains C3+ hydrocarbon vapors. The process uses gas-separation membranes having a base membrane and a coating layer. The base membrane incorporates a selective layer made from a polymer selective between the light gases to be separated. The coating layer comprises a fluorinated polymer capable of protecting the base membrane from C3+ hydrocarbon vapors and liquids.

摘要： A process for treating natural gas or other methane-rich gas to remove excess nitrogen and optionally excess carbon dioxide, water vapor or hydrogen sulfide. The invention relies on gas separation by membranes, using nitrogen/methane selective membranes. The membranes are characterized by having the capability to exhibit a nitrogen/methane selectivity between about 2 and 5 at a temperature higher than about −25° C. The gas may be brought to pipeline specification for nitrogen, and acid gases if present, without requiring the use of amine scrubbing or other acid gas removal technique.

摘要： A process for separating a gas from a gas mixture containing the gas and a C3+ hydrocarbon vapor, using gas-separation membranes selective for the gas over the C3+ hydrocarbon vapor. The membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquid aromatic hydrocarbons.

摘要： A treatment process for a hydrogen-containing off-gas stream from a refinery, petrochemical plant or the like. The process includes three separation steps: condensation, membrane separation and hydrocarbon fraction separation. The membrane separation step is characterized in that it is carried out under conditions at which the membrane exhibits a selectivity in favor of methane over hydrogen of at least about 2.5.

摘要： A process for treating natural gas or other methane-rich gas to remove excess nitrogen and carbon dioxide simultaneously. The invention relies on membrane separation using nitrogen/methane and carbon dioxide/methane selective membranes. The gas can typically be brought to pipeline specification for both components, without requiring the use of amine scrubbing or other acid gas removal technique. Where water vapor or hydrogen sulfide is present in the raw gas, these contaminants may also be removed to meet pipeline specification in a single operation.

摘要： Processes for providing improved methane removal and hydrogen reuse in reactors, particularly in refineries and petrochemical plants. The improved methane removal is achieved by selective purging, by passing gases in the reactor recycle loop across membranes selective in favor of methane over hydrogen, and capable of exhibiting a methane/hydrogen selectivity of at least about 2.5 under the process conditions.

摘要： A process for treating a gas mixture containing at least an organic compound gas or vapor and a second gas, such as natural gas, refinery off-gas or air. The process uses two sequential membrane separation steps, one using membrane selective for the organic compound over the second gas, the other selective for the second gas over the organic vapor. The second-gas-selective membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquid aromatic hydrocarbons. The membrane steps can be combined in either order.
