Patent Number Title Of Patent Date Issued
4234544 Liquid-liquid extraction apparatus November 18, 1980
A relatively large volume horizontal liquid separation chamber is provided as an intermediate part of the downcomers used to transfer the denser liquid phase between contiguous trays of a countercurrent liquid-liquid extraction column. The downcomers also include two smaller vertical
4207174 Liquid-liquid extraction apparatus and process June 10, 1980
A relatively large volume horizontal liquid separation chamber is provided as an intermediate part of the downcomers used to transfer the denser liquid phase between contiguous trays of a countercurrent liquid-liquid extraction column. The downcomers also include two smaller vertical
4104155 Mercaptan extraction process utilizing a stripped alkaline solution August 1, 1978
Water is removed from an alkaline solution used to extract relatively high concentrations of mercaptans from a hydrocarbon stream by stripping the alkaline solution with a hydrocarbon vapor stream. The vapor stream is then admixed with the oxygen-containing off-gas stream of the process
4081354 Liquid-liquid extraction process March 28, 1978
High efficiency in liquid-liquid extraction operations, such as extracting mercaptans from hydrocarbons with caustic, is obtained over a wide range of flow rates through a single extraction column by the provision of an intermediate product drawoff means located between a downstream sect
4040947 Mercaptan extraction process utilizing a stripped alkaline solution August 9, 1977
Water is removed from an alkaline solution used to extract relatively high concentrations of mercaptans from a hydrocarbon stream by stripping the alkaline solution with a hydrocarbon vapor stream. The vapor stream is then admixed with the oxygen-containing off-gas stream of the process
4039389 Liquid-liquid extraction apparatus August 2, 1977
