    摘要： Systems and processes for reducing the energy requirements of an ammonia recovery stripper in a chilled ammonia-based CO2 removal system. The systems and processes include a nanofiltration or reverse osmosis unit for physically separating the washed liquid from a wash vessel configured to receive an ammonia slip feed stream from the main absorber of the chilled ammonia-based CO2 removal system and provide first and second feed streams. Relative to the washed liquid from the wash vessel, the first feed stream has a decreased ammonia molarity whereas the second feed stream has an increased ammonia molarity. The second feed stream is then fed to the ammonia recovery stripper, which reduces steam consumption. The reduced steam consumption translates to significant energy savings, among numerous other advantages. Additionally, the systems and process provide a reduction of equipment sizes related to the stripper unit as may be desired in some applications.

    摘要： A process for removal of CO2 from a gas stream, comprising the steps of: (a) contacting in a CO2 absorption stage a gas stream comprising CO2 with a first absorption liquid comprising ammonia; (b) passing used absorption liquid resulting from step (a) to regeneration; (c) regenerating the first absorption liquid by releasing CO2 from used absorption liquid and returning the first absorption liquid to step (a); (d) supplying CO2 released from step (c) to a second absorption liquid; (e) contacting in a contaminant absorption stage the gas stream leaving step (a) with the second absorption liquid; and (f) withdrawing a portion of used absorption liquid resulting from step (e) and passing said liquid portion to regeneration in step (c), before recycling used absorption liquid resulting from step (e) as second absorption liquid to step (d).

    摘要： A gas stream containing carbon dioxide and sulfur dioxide is cleaned by removing, in a sulfur removal stage, sulfur dioxide from the gas stream. Sulfur dioxide is removed from the gas stream by bringing the gas stream into direct contact with ammonia. The used ammonia may be recycled.In a carbon dioxide removal stage, carbon dioxide is removed from the gas stream depleted in sulfur dioxide by bringing the gas stream into contact with an ammoniated liquid. Following sulfur dioxide and carbon dioxide removal, in an ammonia removal stage, ammonia from the gas stream is removed. Ammonia is removed from the gas stream by bringing the gas stream into direct contact with an acidic liquid to absorb into the acidic liquid, ammonia from the gas stream. The used acidic liquid may be recycled.
