摘要： Separation processes and separation apparatus are described. The process includes introducing a stream of liquid containing dispersed droplets of another liquid into a separation apparatus comprising a vessel having at least one mesh screen covering substantially all of the cross-section of the vessel. The mesh screen is periodically slightly moved so that the wires of the mesh screen contact the dispersed droplets and some of the dispersed droplets coalesce on the wires. The coalesced droplets rise or fall from the wires through the stream of the second liquid. The coalesced droplets are collected in a portion of the vessel. A stream of the second liquid having a reduced level of dispersed droplets is recovered.

摘要： A low pressure re-absorber is integrated with a sulfur-rich solvent flash drum or a sulfur-rich solvent stripping column in a solvent acid gas removal process that provides for sufficient sulfur concentration for the downstream sulfur recovery unit. In another aspect of the invention, carbon dioxide containing or carbon dioxide rich gas streams that are at a lower temperature relative to a lean solvent stream are used to cool those lean solvent streams and then optionally to cool other process streams, to save energy consumption.

摘要： Solvent absorption processes for separating components of an impure feed gas are disclosed. The processes involve two stages of gas purification. The acid gases including hydrogen sulfide, carbon dioxide and other sulfur compounds are simultaneously removed from the feed gas by contact with a physical solvent in two stages. The subject matter disclosed provides improved processes to reduce the operating costs of the system.

摘要： Vapor-liquid contacting apparatuses and methods for removing contaminants from gas streams are provided. In an embodiment, a vapor-liquid contacting apparatus includes a vortex contacting stage having a contacting zone bound by a wall and defining an axis, a radially inner region surrounding the axis, and a radially outer region adjacent the wall. The vapor-liquid contacting apparatus also includes a feed conduit configured to direct flow of a feed gas into the radially outer region of the contacting zone in a direction tangential to the axis to form a vortex. Further, the vapor-liquid contacting apparatus includes a liquid conduit configured to deliver a liquid absorbent stream to the radially inner region in the contacting zone.

摘要： The present invention provides a membrane/amine column system and process for removing acid gases from natural gas on a floating liquefied natural gas vessel. Several process configurations are provided to deal with a reduction in the effectiveness of the amine column by increasing the amount of acid gases being removed by the membrane system prior to the natural gas being sent to the amine column.
