摘要: A gas treatment device uses a gas to be treated which contains an acid compound that dissolves into water to produce acid and a treatment liquid which absorbs the acid compound to phase-separate, to separate an acid compound from the gas to be treated. The gas treatment device includes an absorber which brings the gas to be treated into contact with the treatment liquid; a regenerator 14 which heats the treatment liquid contacting the gas to be treated to separate an acid compound; and a liquid feeding portion which feeds the treatment liquid contacting the gas to be treated in the absorber to the regenerator. In the absorber, the treatment liquid contacting the gas to be treated phase-separates into a first phase portion having a high acid compound content and a second phase portion having a low acid compound content. The liquid feeding portion is configured to introduce, into the regenerator, the treatment liquid with the phase-separated first phase portion and second phase portion mixed.

摘要: Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins, but has not been implemented commercially partially due to the unstable nature of hydrocarbon/oxygen mixtures, and partially due to the cost involved in the construction of new facilities. An oxidative dehydrogenation chemical complex designed to reduce costs by including integration of an oxygen separation module that also addresses safety concerns and reduces emission of greenhouse gases is described.

摘要: A system for carbon dioxide capture from a gas mixture comprises an absorber that receives a lean solvent system stream (containing a chemical solvent, physical-solvent, and water) from the stripper, a stripper that receives the rich solvent stream from the absorber and produces the product carbon dioxide and the lean solvent through the use of a reboiler in fluid communication with a lower portion of the stripper, a condenser in fluid communication with a vapor outlet of the stripper, a cross-exchanger in fluid communication with a rich solvent system outlet from the absorber and a rich solvent system inlet on the stripper, and a splitter. The splitter is configured to separate the rich solvent system stream into a first portion and second portion, where the first portion directly passes to the stripper and the second portion passes through the cross-exchanger prior to passing to the stripper.

摘要: A method for providing upgraded biogas includes feeding a stream of biogas into a biogas upgrading system in order to remove carbon dioxide from the stream of biogas. The biogas upgrading system, which may be based on absorption, adsorption, membrane permeation, and/or cryogenics, provides a stream of upgraded biogas and a tail gas stream. The tail gas stream, which may be CO2-rich, is enriched with natural gas so that it is combustible in medium-BTU equipment. The upgraded biogas is used for transportation use and/or the generation of fuel credits. Accordingly, both the tail gas and the upgraded biogas are used effectively and at lower cost.

摘要: The invention relates to gas separation, particularly to a process for separating CO2 from a CO2 containing gas stream with varying CO2 concentration using a membrane-based separation system. The process for separating CO2 comprises: (i) feeding the CO2 containing gas stream into a membrane-based separation system comprising one or more membrane stages in-line, each membrane stage producing a CO2-depleted retentate stream and a rich CO2 permeate stream, and (ii) recycling a part of the CO2-rich permeate stream from at least one membrane stage as a recycled stream, into a preceding feed stream of one or more membrane stages in the membrane-based separation system to adjust the CO2 concentration of the feed stream. The process could stabilize the CO2 concentration in the feed steam by recirculation of a fraction of the high purity CO2 permeate to the feed of the membrane system, which would result in a lower incremental auxiliary load than other options such as compression of the entire gas stream.
