The present application provides systems, apparatuses, and methods for simultaneous processing of tow waster gases, namely H.sub.2S and CO.sub.2. In an exemplary process of this disclosure H.sub.2S is supplied to anode side of an electrochemical cell, while CO.sub.2 is supplied to the cathode side. As a result, valuable commercial products are produced. In particular, SO.sub.2 is harvested from the anode side, while synthesis gas, CO+H.sub.2) is harvested from the cathode side. An electric current is also produced, which can be supplied to a local utility grid.

A power-to-X system having an electrolyzer and an energy converter which are connected together via a hydrogen line. The system additionally has a chemical reactor for catalytically removing oxygen, a first heat exchanger, a water separator, a store, and a humidifier which are connected into the hydrogen line in the stated order one behind the other between the electrolyzer and the energy converter. A second heat exchanger is arranged in the hydrogen line such that a first side of the second heat exchanger is arranged in front of the first heat exchanger and a second side of the second heat exchanger is arranged downstream of the water separator in the hydrogen line.

The process and apparatus according to the invention allow the production of hydrocarbons and ammonia without the use of catalysts. For this purpose, waste gases containing CO.sub.2 or N.sub.2 from an upstream process are fed to compression reactors. In addition, hydrogen from an electrolyzer is fed to these reactors to enable hydrogenation of the fed substances. Methane, alcohols and ammonia, for example, can be produced by this process. In order to increase the yield of the process, it is planned to raise the reactant pressure with the aid of a compressor.

An ammonia derivative production plant includes: an electrolyzer for electrolyzing water; an ammonia synthesis system for synthesizing ammonia from hydrogen produced by the electrolyzer and nitrogen; a carbon dioxide generation system for producing carbon dioxide; and an ammonia derivative synthesis system for synthesizing an ammonia derivative from ammonia synthesized by the ammonia synthesis system and carbon dioxide produced by the carbon dioxide generation system. Oxygen produced by the electrolyzer is consumed to produce carbon dioxide by the carbon dioxide generation system.

An electrolyzer system includes a steam generator configured to generate steam, a stack of solid oxide electrolyzer cells configured to generate a hydrogen stream using the steam received from the steam generator, and a water preheater configured to preheat water provided to the steam generator using heat extracted from oxygen exhaust output from the stack.
