Abstract
In a novel method for start-up heating of a converting re-actor in an ammonia synthesis plant, the conventional use of a gas fired heater is replaced by inductive heating. The inductive heating is obtained using an alternating high frequency current, which is passed through an inductive coil located inside the reactor, especially mounted inside a pressure shell. The method makes it possible to run reactions at high temperatures and high pressures in a very efficient way.
Claims3
A method for start-up heating of a converting reactor in an ammonia synthesis plant, by inductive heating, comprising passing an alternating high frequency current through an inductive coil, wherein the inductive coil is located inside a pressure shell of the reactor, an ammonia catalyst is placed inside the coil, and the coil is uninsulated, whereby the coil is in electrical contact with the catalyst.
