摘要： A recovery plant for recovery of a gaseous component from a process gas has an absorber employing a lean solvent and a semi-lean solvent that absorb the gaseous component from the process gas, thereby producing a rich solvent, a semi-rich solvent, and a lean process gas. A regenerator extracts the gaseous component from the rich solvent, thereby regenerating the lean solvent and the semi-lean solvent. A solvent flow control element combines at least part of the semi-rich solvent and the semi-lean solvent to form a mixed solvent, and a cooler cools the mixed solvent that is subsequently fed into the absorber. In a method of removing a gaseous component from a process gas, a stream of lean solvent and a stream of semi-lean solvent are provided. In another step, the stream of lean solvent and the stream of semi-lean solvent contact the process gas in an absorber to produce a stream of semi-rich solvent and rich solvent. In a further step, at least part of the stream of semi-rich solvent and semi-lean solvent are combined to form a mixed solvent stream, and a cooler cools the mixed solvent stream, which is introduced into the absorber to absorb the gaseous component.

摘要： In a process for dehydration/fractionation of a wet natural gas containing heavy constituents and light constituents, In the presence of methanol, aqueous liquid phases are combined and the resultant combined aqueous liquid phase contacted with the first part of the gas to be scrubbed, which carries along the major part of the methanol, which allows to collect practically pure water. Before this step, all or part of one or both of the aqueous liquid phases and/or all or part of the aqueous liquid phase from a washing zone is sent to a distillation stage where practically pure methanol is collected at the top and a methanol-depleted aqueous liquid phase is collected at the bottom prior to being sent back to the first stage or used for the washing stage.

摘要： A method of removing hydrogen sulphide from a gas stream wherein the hydrogen sulphide is scrubbed from the gas phase by an aqueous solution, the hydrogen sulphide in the aqueous solution is biologically oxidized in a bioreactor to produce elemental sulphur, and the elemental sulphur is separated from the aqueous solution, characterized in that the gas stream to be treated is cooled to such a degree that at least sufficient water vapour condenses from the gas stream to compensate for the discharge stream for the purpose of removing salts. This means that no water need be supplied to the bioreactor. This method is suitable, in particular, for gas streams which contain hydrogen sulphide, the hydrogen sulphide having been obtained by catalytic conversion of sulphur compounds.

摘要： In a process for treating a gas containing acid gases, the gas is contacted with a methanol-containing aqueous phase and is then contacted in an absorption column with a mixture of solvents including mehtanol, water and a solvent heavier than methanol. Then, the mixture of solvents is at least partly regenerated through pressure reduction and/or heating. The treated gas is cooled by producing at least a methanol-containing aqueous phase that is at least partly recycled. The mixture of solvents flowing out at the bottom of the absorption column is cooled, then re-introduced at a higher level of the absorption column so as to control the temperature in the absorption column.

摘要： A process and system for producing fertilizers with reduced levels of contaminants, and particularly a flue gas scrubbing process and facility that produce a fertilizer byproduct which is treated to remove heavy metals originally present in the scrubbed flue gas. The process entails contacting a flue gas with a scrubbing solution to remove acidic gases and produce a byproduct containing a fertilizer compound precipitate and dissolved metals and/or metal compounds. A fertilizer solution containing dissolved fertilizer and dissolved metals and/or metal compounds is then produced by adding water to the byproduct, after which the pH of the fertilizer solution is adjusted one or more times with a gaseous and/or liquid alkali to form precipitates of one or more metal species. The precipitates are then removed from the fertilizer solution and the solution dewatered to yield a fertilizer product with lower contaminant levels.

摘要： A system and method for treating process gas streams containing isopropyl alcohol (IPA) to reduce the concentration of IPA therein. The invented system includes a scrubber unit that receives a process stream containing a concentration of IPA and reduces the concentration of IPA therein to below a determined threshold. The scrubber includes a reverse osmosis assembly that significantly reduces water consumption for the scrubbing process as compared to conventional once-through systems. The system may be operated at an elevated pH to prevent biofouling from inhibiting the operation of the reverse osmosis assembly. The system may contain a softening step on the make up water system to prevent scaling in the reverse osmosis system and a softening step on a sidestream of the scrubber water recirculation loop to reduce scrubber tower salting/scaling and to control the pH of the scrubbing liquid.
