METHOD FOR RECOVERING PROCESS CONDENSATE
A method and a system for producing synthesis gas, wherein process condensate is used to produce steam. To this end, steam is used to strip volatile impurities, in particular carbon dioxide, from the process condensate and then preferably convert the impurities together with flue gas and discharge them. Then a pH of at least 7.0 is preferably set by adding additives, the process condensate being evaporated and recycled as output steam for producing synthesis gas. In this way, it is possible to suppress the corrosive effect of the process condensate such that no, or less, corrosion-resistant stainless-steel must be used in the manufacture of the system components that come into contact with the process condensate. The steam used to strip the volatile impurities is preferably generated by heat from the synthesis gas and/or flue gas.
Reactor
In a reactor comprising a cylindrical combustion chamber, at least one burner and a circular array of catalyst-containing tubes, there is provided a ring baffle on the wall opposite the burner(s) extending into the combustion chamber which redirects combustion gas around the combustion chamber, thereby enabling more even heat distribution and an increase in overall heat transfer.

Pre-combustion CO2 removal in a natural gas fed steam methane reformer (SMR) based hydrogen plant
In a hydrocarbon-fed steam methane reformer hydrogen-production process and system, carbon dioxide is recovered in a pre-combustion context, and optionally additional amounts of carbon dioxide are recovered in a post-combustion carbon dioxide removal, to provide the improved carbon dioxide recovery or capture disclosed herein.
Electrochemical element, electrochemical module, electrochemical device, and energy system
In the electrochemical element, a plate-like support includes an internal passage through which a first gas flows, a gas-permeable portion, and an electrochemical reaction portion in which a film-like electrode layer, a film-like electrolyte layer, and a film-like counter electrode layer are stacked so as to entirely or partially cover the gas-permeable portion. The internal passage includes a plurality of auxiliary passages through which the first gas flows in a predetermined flowing direction, and a distribution portion provided on the upstream side of the plurality of auxiliary passages in the flowing direction of the first gas. The plate-like support includes a supply structure that is located between the distribution portion and the auxiliary passages in the flowing direction. The first gas is temporarily stored in the distribution portion and supply of the first gas from the distribution portion to the plurality of auxiliary passages is limited.

Various methods and apparatuses for multi-stage synthesis gas generation
A multiple stage synthesis gas generation system is disclosed including a high radiant heat flux reactor, a gasifier reactor control system, and a Steam Methane Reformer (SMR) reactor. The SMR reactor is in parallel and cooperates with the high radiant heat flux reactor to produce a high quality syngas mixture for MeOH synthesis. The resultant products from the two reactors may be used for the MeOH synthesis. The SMR provides hydrogen rich syngas to be mixed with the potentially carbon monoxide rich syngas from the high radiant heat flux reactor. The combination of syngas component streams from the two reactors can provide the required hydrogen to carbon monoxide ratio for methanol synthesis. The SMR reactor control system and a gasifier reactor control system interact to produce a high quality syngas mixture for the MeOH synthesis.
Process for enabling carbon-capture from existing combustion processes
A process of producing a feed from a solid oxide electrolysis cell. A first portion of the flue gas produced from a combustion process is directed to the anode side of the solid oxide electrolysis cell. The feed and a second portion of the flue gas are then mixed to produce an enhanced feed. The enhanced feed is then mixed with fuel and combusted in the combustion process to produce flue gas. The flue gas comprises greater than 50 wt % CO.sub.2 and less than 1 wt % N.sub.2.
