摘要： A method of treating sour water from industrial processes such as coal gasification. The method includes injecting a polysulfide into a sour water stream to convert cyanide to thiocyanate, thereby reducing the corrosiveness and toxicity of the sour water stream. The method also includes mixing the sour water stream with a reactant to remove CO 2 in its various forms in a reaction tank and subsequently routing the stream to a solid settler. The method further includes adjusting the pH of the sour stream in a pH correction tank before sending the sour water stream through a stream stripper for H 2 S and/or NH 3 removal. After passing through the stripper, the treated sour water stream is sent to a biological treatment process for thiocyanate and formate removal. Subsequent treatment steps can be applied, such as multi-grade filters and activated carbon filters, to prepare the treated sour water for reuse.

摘要： Plants, processes, and methods for reducing the H 2 S and CO 2 contents of shale gasses from fields that produce shale gasses having varying H 2 S and CO 2 contents are provided. Acid gas enters an absorber and is scrubbed using a lean physical solvent, producing a treated gas and a rich physical solvent. The H 2 S content of the treated gas is further reduced in an amine absorber, producing a pipeline gas and a semi-lean amine. The pipeline gas contains lower levels of H 2 S and CO 2 than gas produced using a polishing bed. A physical solvent regeneration unit regenerates the lean physical solvent from the rich physical solvent for feeding into the absorption unit. An amine regeneration unit regenerates the lean amine from the semi-lean amine for feeding into the amine absorber. Contemplated plants may further comprise a Claus Unit or a Redox unit for oxidizing H 2 S to elemental sulfur.

摘要： A plant includes a pretreatment unit for H2S removal and air dehydration, and at least two absorbers that receive a feed gas at a pressure of at least 300 psig with variable CO2 content ( e.g. , between 5 to 60 mol%), wherein the feed gas is scrubbed in the absorbers with an ultralean and a semi-lean physical solvent, respectively, at low temperatures to at least partially remove the CO2 from the feed gas. Such configurations produces a low CO2 dry treated gas and a H2S-free CO2 for sequestration while advantageously providing cooling by expansion of the rich solvent that cools the semi-lean solvent and the feed gas, wherein an ultralean solvent is produced by stripping using dry air.

摘要： Contemplated gas-liquid separators and especially subsea gas-liquid separators have a main pipe with a plurality of descending branch pipes that are fluidly coupled to the main pipe and each other such as to allow disengagement of the gas into the main pipe while liquid and sand descend into the lower ends of the branch pipes. Sand accumulation in the lower ends of the branch pipes is preferably prevented by lateral serial flow of liquid and sand from one branch pipe to the next and use of a flush liquid that is drawn from one or more branch pipes.
