    摘要： A process for the synthesis of ammonia from a hydrocarbon feedstock, wherein the process includes reforming the hydrocarbon feedstock to produce a make-up gas and converting said make-up gas into ammonia, the process is performed in an ammonia synthesis plant requiring an electric power for operation and also requiring a start-up power (Ps) for start-up, wherein a first electric power (P1) is internally produced in the ammonia plant, and a second electric power (P2) is imported, wherein said second electric power is equal to or greater than said start-up power (Ps).

    摘要： An industrial gas production plant operable to produce a feedstock gas at a variable production rate for supply to the downstream process; and a gas storage resource operable to store produced feedstock gas, the method comprising: determining the pressure of feedstock gas in a supply feed line to the downstream process; selectively controlling, using a control system, a flow of feedstock gas from the supply feed line to the gas storage resource or from the gas storage resource to the supply feed line in response to the determined pressure in order to regulate the pressure of the feedstock gas in the supply feed line to the downstream process at a predetermined set point pressure; and selectively controlling, using a control system, a flow rate of feedstock gas in the supply feed line to the downstream process in dependence upon at least one operational parameter of the gas storage resource.

    摘要： A syngas production system includes a gasification reactor and a syngas pressure vessel downstream of the gasification reactor. The syngas pressure vessel includes a pressure vessel having a body with a first portion and a second portion. The syngas pressure vessel also includes an evaporator disposed in the pressure vessel; a coil disposed in the pressure vessel; and a tongue-and-groove flange assembly. The tongue-and-groove flange assembly includes: a first flange with a raised ring extending from a face of the first flange, the first flange attached to the first portion of the body; a second flange with a groove defined in a face of the second flange. The second flange is attached to the second portion of the body. The raised ring extends from the face of the first flange and is positioned in the groove defined in the face of the second flange.
