A method of compressing a gas includes pumping, using a pump, at least a portion of a liquid contained in a first chamber to a second chamber containing a gas at a first pressure such that the portion of the liquid pumped into the second chamber compresses the gas in the second chamber to a second pressure greater than the first pressure, wherein the portion of the liquid pumped into the second chamber is admitted into the second chamber so that the admitted liquid flows along an internal surface of the second chamber.

The invention relates to an absorber column and to the use thereof for separation of unwanted, especially acidic, gas constituents, for example carbon dioxide and hydrogen sulfide, from a crude synthesis gas by absorption with an absorbent, especially under low load states of the absorber column in relation to the synthesis gas velocity. According to the invention, a defined concentration of carbon dioxide in the clean synthesis gas is established by mixing at least a portion of the absorbent regenerated by flash regeneration with the absorbent regenerated by means of hot regeneration prior to the recycling thereof into the absorber column.

The invention relates to dispersions of porous solids in liquids selected from deep eutectic solvents, liquid oligomers, bulky liquids, liquid polymers, silicone oils, halogenated oils, paraffin oils or triglyceride oils, as well as to their methods of preparation.

The present process invention in continuation to the U.S. Ser. No. 14/392,066 appertains to Advanced Combustion in post-combustion carbon capture, wherein the CO.sub.2-containing flue gas, said CO2-Stream, is cleaned from harmful constituents, recirculated, oxygenized and employed for combustion for the fossil fuels, referred to Flue Gas Oxy-Fueling in order to obtain a CO.sub.2-rich gas upstream to CO2-CC with significantly less gas flow rate subject to further processing. This continuation process patent also presents processing to prepare a CO.sub.2-rich CO2-Stream for the pre-combustion carbon capture downstream of gasification and gas cleaning process; or from the secondary CO2-Stream that stems from the cathodic syngas [CO/2H.sub.2] downstream of HPLTE-SG of patent parent, then downstream of the HP/IP-water shift converters in [CO.sub.2/3H.sub.2] composition, whereas the CO.sub.2-rich CO2-Stream from either pre-combustion process is routed to the CO2-CC for CO.sub.2 cooling and condensation section of the U.S. Ser.
