||PCT/CA2014/050359||IONADA INCORPORATED||PANZIERA, Edoardo|
There is disclosed a method and apparatus to reduce emissions of target emission gasses such Sulfur Oxides, Nitrogen Oxides, and Carbon Oxides from combustion exhaust such as marine engine exhaust by gas membrane separation and liquid carrier chemical absorption. The membrane separation system consists of an absorption system containing semi-permeable hollow fiber membranes through which is circulated a liquid absorbent. Exhaust gases contact the exterior surface of the membranes and the target gasses selectively permeate the membrane wall and are absorbed by the liquid carrier(s) within the bore and thereby removed from the exhaust stream.

||PCT/EP2014/062148||SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ B.V.||ITO, Eri|
The present invention provides a process for the oxidation of hydrogen sulphide (H2S) in an H2S-containing hydrocarbon feed gas to elemental sulphur. In the process a H2S-containing hydrocarbon feed gas (10) and a sulphur dioxide containing gas (20) are contacted in a catalytic zone (3) at a temperature of 120 to 200°C, and a pressure of 4 to 200 bara, thereby forming elemental sulphur which is essentially in liquid form. A stream (30) containing the elemental sulphur and a first H2S-depleted gaseous stream (50) are removed from the catalytic zone (3). The first H2S-depleted gaseous stream (50) is separated, thereby obtaining a concentrated H2S-containing gaseous stream (60) and a second H2S-depleted gaseous stream (70). The concentrated H2S-containing gaseous stream (60) is incinerated, thereby obtaining a SO2-containing stream (80). At least a part of the SO2-containing stream (80) is used as the SO2-containing gas (20) supplied in step (b).

Systems and methods for gas separation are disclosed. In one exemplary embodiment, a method for gas separation includes the steps of contacting a feed gas stream that includes a product gas and an impurity gas with a liquid-phase absorption solvent and absorbing the impurity gas and a portion of the product gas of the feed gas stream into the liquid-phase absorption solvent. The exemplary method further includes the steps of subjecting the liquid-phase absorption solvent to a first reduced pressure environment to remove the portion of the product gas and a portion of the impurity gas from the liquid-phase absorption solvent and separating the portion of the product gas from the portion of the impurity gas.

-loaded absorbent solution is then heated and expanded at a predetermined pressure and a predetermined temperature so as to release a gaseous fraction comprising hydrocarbons and to obtain a hydrocarbon-depleted absorbent solution, said pressure and said temperature being chosen such that said gaseous fraction comprises at least 50% of the hydrocarbons contained in said CO2
-loaded absorbent solution and at most 35% of CO2
contained in said CO2
-loaded absorbent solution. Finally, the hydrocarbon-compound-depleted absorbent solution is thermally regenerated
