    摘要: A method for producing ammonia by catalytically reacting hydrogen provided in a first feed stream and nitrogen provided in a second feed stream is proposed, the hydrogen in the first feed stream being at least in part formed by water electrolysis and the nitrogen in the second feed stream being at least in part formed by cryogenic air separation, wherein said cryogenic air separation is performed using an air separation unit comprising a rectification column system, a recycle stream being formed in the air separation unit from a gas stream at least predominantly comprising nitrogen which is withdrawn from the rectification column system, the recycle stream being, in the order indicated, compressed, cooled, expanded and reintroduced into the rectification column system, and wherein waste heat from said catalytically reacting hydrogen and nitrogen is transferred to a steam system providing steam.

    摘要: Process for reducing CO2 and membrane separation arrangement. A process/arrangement for reducing the CO2 content of a gas mixture using four membrane separation steps, two of the separation steps using glassy membrane and two using rubbery membrane. A first retentate is withdrawn from the first separation step at a first withdrawal pressure and temperature and is supplied to the second separation step, a second retentate is withdrawn from the second separation step at a second withdrawal pressure and temperature and is supplied to the third separation step, a third retentate is withdrawn from the third separation step at a third withdrawal pressure and temperature and is supplied to the fourth separation step, permeates of the separation steps using the glassy membrane are combined to form a first combined permeate stream, and permeates of the separation steps using the rubbery membrane are combined to form a second combined permeate stream.

    摘要: A method of steam cracking using a steam cracking arrangement including an electric cracking furnace without a convection zone and a quench cooling train is proposed, wherein a process gas stream is passed through the cracking furnace and the cooling train. The cooling train is operated to comprise at least two distinct cooling steps arranged in either order, wherein in a first cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against vaporizing boiler feed water at an absolute pressure level between 30 and 175 bar and wherein in a second cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against a superheated mixture of feed hydrocarbons and process steam used in forming the process gas stream which is thereby heated to a temperature level between 350 and 750° C.

    摘要: A reactor for carrying out a chemical reaction includes a reactor wall and at least one group of M reaction tubes, each of which has an electrically heatable heating section that extends between a first and a second removal region. Each heating section has a respective feed region in a region which extends over 20% to 80% of a heating length of the heating section and electrically conductive feed elements. Each group M is paired with the feed elements connected to the feed regions of the group, and different phases of the alternating current can be fed to different feed elements paired with a group. Each group is paired with M first and M second removal elements connected to the first or second removal regions of the group, respectively. Each group is paired with a first and a second star bridge.

    摘要: A cryogenic tank-filling arrangement having a coupling device and a receptacle, wherein the coupling device and the receptacle are designed to be complementary to each other, wherein the cryogenic tank-filling arrangement can be brought with the aid of a pressure change in the intermediate space from an unlocked state—in which the coupling device and the receptacle are accommodated in each other at least in sections, so that the coupling device and the receptacle enclose an intermediate space which is closed off relative to an environment of the cryogenic tank-filling arrangement and which is arranged between an end face of the coupling device and an end face of the receptacle—into a locked state, in which the end face of the coupling device is pressed against the end face of the receptacle due to the pressure change.
