摘要： The objective of the present invention is to treat waste water appropriately. This CO2 recovery system comprises: a combustion facility; a dust collector into which exhaust gas containing CO2, discharged from the combustion facility, is introduced, and which removes solid components from the exhaust gas; an exhaust gas cooling device into which the exhaust gas is introduced, and which cools the exhaust gas by bringing the same into contact with cooling water; a CO2 absorption tower into which the exhaust gas cooled by the exhaust gas cooling device is introduced, and which removes the CO2 from the exhaust gas by bringing the exhaust gas into contact with a CO2 absorbent; and a cooling water introduction line which is connected to the exhaust gas cooling device and to a supply site, which is a site on an upstream side, in the flow of exhaust gas, of the dust collector, and which guides at least a portion of the cooling water inside the exhaust gas cooling device to the supply site.

摘要： This invention discloses a hydrogenation method of CaCO3 with H2 to produce CaO and a syngas product gas containing H2, CO, CO2 and H2O, preferably with a H2/CO mol ratio close to 2. The method operates by arranging a solids containing CaCO3 and at least CaO (as reverse water gas shift catalyst) in a reactor, heating them to a temperature that depends on operating pressure and feeding H2 to react with them and cause a cooling of the solids while producing a syngas and a solids mixture containing an increased fracstion of CaO. The method operates continuously by cyclically recarbonating the CaO with the CO2 contained in a gas, or by feeding new CaCO3 to the bed of solids and extracting an equimolar quantity of CaO.

摘要： Method and installation for calcining cement raw meal in a calciner (10) whereby fuel and a calciner oxidant having an oxygen content of at least 30% vol are introduced into the calciner (10) so as to generate either an oxidant-lean zone or a fuel-lean zone in the calciner located between the lowermost fuel inlet level (L13) and the lowermost oxidant inlet level (L16) of the calciner (10), between 50% and 100% by weight of the raw meal (14, 15) being supplied to the calciner (10) upstream of and/or within the oxidant-lean, respectively the fuel-lean zone.

摘要： A processes is for purifying an amine compound from a feed solvent which includes an amine salt of the amine compound. The process includes heating the feed solvent in a single stage evaporator of a reclaimer at a reduced operating pressure by feeding the evaporator with a constant amount of thermal energy; and evaporating the amine compound to purity the amine compound from the feed solvent.

摘要： An example method of removing hydrogen sulfide from an input gas includes exposing an adsorbent material to an input gas to obtain an output gas. A concentration of hydrogen sulfide of the output gas is less than a concentration of hydrogen sulfide of the input gas. The adsorbent material includes copper oxide, magnesium oxide, and aluminum oxide. An atomic ratio of copper to magnesium to aluminum of the adsorbent material is X:Y:Z, where X is greater than or equal to 0.6 and less than or equal to 0.9, where Y is greater than or equal to 0 and less than or equal to 0.2, where Z is greater than or equal to 0 and less than or equal to 0.2, and where X+Y+Z is equal to 1.
