    摘要： A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.

    摘要： 2,4′-MDI which contains very little 2,2′-MDI is prepared by distilling an isomeric starting mixture of diisocyanatodiphenylmethanes which includes 2,2′-diisocyanato-diphenylmethane, 2,4′-diisocyanatodiphenylmethane and 4,4′-diisocyanatodiphenyl-methane in at least one stage in a separating wall column. This distillation produces at least one mixture which contains 85 to 99 wt. % of 2,4′-diisocyanatodiphenylmethane, up to 15 wt. % of 4,4′-diisocyanatodiphenyl-methane and no more than 0.2 wt. % of 2,2′-diisocyanatodiphenylmethane.

    摘要： A novel steam reformer unit design, a novel hydrogen PSA unit design, a novel hydrogen/nitrogen enrichment unit design, and novel processing scheme application are presented. The result of these innovations results in re-allocating most of the total hydrogen plant CO2 emissions load to high pressure syngas stream exiting the water gas shift reactor while minimizing the CO2 emissions load from the reformer furnace flue gas. As compared to the conventional 60/40 split of total CO2 emissions in syngas/flue gas streams for steam reformer based conventional hydrogen plant designs, the present invention results in 85/15 or better CO2 split. This will permit about 85% or better of the total CO2 emissions load to be captured from the syngas stream, using the conventional, well proven and cost effective amine scrubbing technology. Such 85% or better CO2 capture is much greater than the 55% to 60% maximum possible using conventional steam reformer based hydrogen plant technology. As CO2 recovery from high pressure syngas stream is much easier and cost effective as compared to that from low pressure reformer furnace flue gases, a major cost benefit for equivalent CO2 recovery results with the present invention.

    摘要： A heat-insulating wall, such as a refrigerator door or housing, includes a substantially vacuum-tight outer paneling, an inner paneling, a substantially vacuum-tight connecting diaphragm formed from material having low heat conduction, a diaphragm cover formed from material having low heat conduction, and a protective profile with an opposite magnetic pole or a magnetic seal. The diaphragm is respectively vacuum-tightly connected to the inner paneling and to the outer paneling at free borders thereof. The outer paneling, the diaphragm, and the inner paneling define an evacuable cavity that is filled with an evacuable supporting material. The diaphragm cover covers at least a part of the diaphragm. The protective profile is secured one or both of the inner paneling and the outer paneling and substantially covers the diaphragm cover.

    摘要： In a process for producing synthesis gas by catalytic conversion of hydrocarbons contained in a desulfurized feed gas stream with steam, the mixture of feed gas and steam is preheated by heat exchange at a pressure of 10 to 45 bar to a temperature of 300 to 700° C. and is subsequently heated by heat exchange above a catalyst at a pressure of 10 to 45 bar to a temperature of 650 to 950° C. To minimize the apparatus involved, it is provided that the mixture of feed gas and steam traverses a catalyst bed contained in a reaction tank, and the catalyst bed is heated by thermal radiation and convection.
