    摘要： An apparatus for heating a fluid in a process having a process heat requirement includes a shell, at least one tube having a design temperature inside the shell, a plurality of burners adjacent the inner wall of the shell, and transfer means whereby flue gas flows from a first interior region to a second interior region of the shell. A first portion of the tube is in the first interior region and a second portion of the tube is in the second interior region. The first and second portions of the tube are adapted to contain a flow of the fluid. The burners produce the flue gas in the first interior region and a variable heat flux approximating the process heat requirement and simultaneously maximizing the heat flux to the first portion of the tube while maintaining substantially all of the first portion of the tube at the design temperature.

    摘要： Method for the production of methanol and hydrogen which comprises steam reforming a hydrocarbon-containing feed in a steam reforming zone to yield a synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide; introducing a first portion of the synthesis gas into a methanol synthesis zone to form methanol; reacting a second portion of the synthesis gas with steam to convert carbon monoxide to hydrogen and carbon dioxide to yield a shifted synthesis gas; cooling the shifted synthesis gas to yield a cooled shifted synthesis gas; separating the cooled shifted synthesis gas into a high-purity hydrogen product stream and a reject stream enriched in carbon dioxide; and introducing some or all of the reject stream into either or both of the steam reforming zone and the methanol synthesis zone.

    摘要： An ammonia synthesis gas mixture comprised of substantially pure hydrogen and nitrogen in approximately 3/1 molar ratio is obtained form two stage reforming of a methane-rich hydrocarbon charge such as natural gas. About 40% of the fresh natural gas is charged to primary steam reforming and the obtained primary reformate product, containing about 17 volume percent of unreacted methane, is mixed with the other 60% of the fresh natural gas and the mixture is subjected to oxidative reforming with enriched air containing 30 to 35 of O.sub.2, said enriched air being supplied in an amount to produce a secondary reformate containing principally hydrogen and nitrogen, accompanied by a minor amount of oxides of carbon (CO and CO.sub.2). The secondary reformate subjected to shift reaction with steam results in conversion of contained CO to CO.sub.2, thereby releasing hydrogen in an amount which together with the hydrogen previously present in said reformate obtains a H.sub.2 /N.sub.2 molar ratio of about 3/1. Carbon dioxide is removed and recovered from the shift reaction product by pressure swing adsorption in a first adsorbent bed. The other contaminants remaining are largely removed by further adsorption in second adsorbent bed in flow-communication with the first bed, the unadsorbed effluent being a syngas mixture consisting essentially of hydrogen and nitrogen in stoichiometric ratio for production of NH.sub.3.
