Abstract: Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. The reactor system may include a reactor vessel configured to receive a reactor fluid through a reactor fluid inlet and a product source fluid corrosive to portions of the reactor system through a product source fluid inlet. The product source fluid may react with the reactor fluid to produce one or more reaction products, such as a fuel gas. The product source fluid inlet may be arranged within the reactor fluid inlet such that the product source fluid entering the reactor vessel is encased by a fluid conduit formed by the flow of reactor fluid entering the reactor vessel. The layer may operate to reduce corrosion by forming a barrier between the product source fluid and the surface of the reactor fluid inlet and/or the reactor vessel.

Abstract: The present invention provides a weir quench, an apparatus utilizing the weir quench and processes incorporating the same. The weir quench incorporates an inlet having an inner diameter (Di) and an upper chamber having an inner diameter (Duc), wherein the inlet inner diameter (Di) is at least 90% of the upper chamber inner diameter (Duc). The apparatus constitutes a reactor having an outlet with an inner diameter fluidly coupled with the weir quench inlet, wherein the ratio of the reactor oulet inner diameter (Dr) to the weir quench inlet diameter (Di) is greater than one. The weir quench, and apparatus are advantageously utilized in processes utilizing a limiting reagent.
