The reactor is a vertical tubular reactor. The catalyst is contained inside the tubes (typically 2000 to 4000 tubes, 7 m long) and on the outside of the tubes; boiling water is used to remove the heat from the exothermic reaction-taking place inside the tubes. The catalyst in the tubes is loaded tube by tube through the top of the reactor.
