초록 ▼

A methanation reactor, to be used preferably in an integrated urea-ammonia process for methanizing carbon oxides is disclosed, in which the catalyst bed and an underlying heat exchanger of the tube-bundle type make up a unit mounted centrally of the reactor casing with a gap left between the reactor casing inside wall and said centrally mounted unit. Fresh gases to be methanized enter the gap, then the heat exchanger from below and flow upwards to the catalyst bed, whereafter they flow down to the exchanger again. Incoming gases sweep the exchanger tubes from the outside, while the reacted gases flow in the interior of the tubes of the heat exchanging bundle. Insulation blankets and gland seals are provided.

대표청구항 ▼

A methanation reactor comprising an outer metal casing having a removable lid mounted to the top portion of said casing, said lid having an aperture extending therethrough for introducing gases to be reacted into the outer casing, an inner casing having cover means and positioned within said outer casing in circumferentially spaced and supported relationship therefrom forming an axially extending vertical gap between said inner and outer casings for the downward vertical passage therethrough of gases to be reacted, a toroidal catalyst bed positioned in the upper portion of said inner casing, a transverse grid having a plurality of alumina balls located thereon positioned within said casing and supporting said catalyst bed, a heat exchanger assembly mounted within said inner casing below and in downwardly spaced relationship from said catalyst bed, said heat exchanger assembly including an upper horizontal tube sheet, a lower horizontal tube sheet and a plurality of vertical tubes connected at their respective upper and lower ends to said upper and lower tube sheets, said heat exchanger assembly also including a plurality of baffles to direct the upward flow of incoming gases within said heat exchanger assembly, said inner casing having a plurality of windows circumferentially spaced at the bottom end thereof below said heat exchanger assembly through which gases to be reacted will enter the inner casing from the lower end of the gap formed between the inner and outer casings, insulation means enveloping the outer surface of said inner casing from the top thereof down to the windows therein, a gas outlet tube centrally positioned within the upper portion of said inner casing, said outlet tube having its lower end mounted to the upper tube sheet of and extending into said heat exchanger assembly and its upper end extending through the beyond said catalyst bed, a central feed tube extending through the aperture in the lid of the outer casing and through the cover means of said inner casing and terminating at a point just above the upper end of the gas outlet tube for the passage of hot gases into the inner casing of said reactor, and gas discharge means centrally connecting at one end to the bottom of said inner casing and extending through the bottom end of said outer casing to provide an exit for reacted gases from the reactor, whereby the gases to be reached are fed initially through the aperture in the lid into the outer casing and thereafter downwardly through the gap between the inner and outer casings, then through the windows in the lower end of said inner casing and upwardly through the heat exchange assembly and about the tubes for preheating of the gas and thereafter collected in the upper end of the heat exchange assembly and fed upwardly through said gas outlet tube above the catalyst bed and then fed downwardly through the catalyst bed surrounding the gas outlet tube and then into and through the heat exchanger tubes and then downwardly through the gas discharge means in the bottom of the inner casing.
