摘要： An object of the present invention is to carry out separation recovery of ammonia efficiently from a gaseous mixture containing ammonia and carbon dioxide, without generating a solid ammonium carbamate. A recovery method of ammonia from a gaseous mixture, includes a process (I) in which a gaseous mixture containing ammonia and carbon dioxide is contacted with an organic solvent to allow the organic solvent to absorb ammonia in the gaseous mixture, and a process (II) in which the organic solvent which absorbed ammonia is distilled to separate ammonia from the organic solvent.

摘要： In a crystallization method, a liquid mixture containing a crystallizable component is cooled so as to form and separate crystals of the crystallizable component. Then, a purified melt having purity substantially equal to that of the separated crystals, to which a polymerization inhibitor is added and which is heated to a temperature higher than a freezing point of the separated crystals, is circulated to flow contacting the crystals so as to accelerate melting. Then, the melted crystals are recovered along with the purified melt containing the polymerization inhibitor.

摘要： Disclosed is a method for production of lower olefins from a raw material containing dimethyl ether (DME), which can produce lower olefins (e.g. propylene) with good yield and in an economically advantageous manner by prolonging the time until the reversible deactivation of a zeolite catalyst and preventing the irreversible deactivation of the catalyst, can reduce the amount of water to be recycled to increase the thermal efficiency of the process, and can simplify the facilities and operations. Also disclosed is a method for improving the yield of propylene with good efficiency under practical operating conditions. A feed gas which comprises a DME-containing feedstock gas and an additive gas and further contains steam at a specific proportion is introduced into an olefin synthesis reactor to contact the feed gas with a zeolite catalyst, thereby producing a hydrocarbon product containing C2-C5 olefins. Propylene or the like is separated/collected from the hydrocarbon product, and at least a part of the remainder is used as at least a part of the additive gas.
