Abstract
Disclosed is a method of increasing the capacity of an existing urea plant. With reference to the regular components of a urea plant, including a synthesis section comprising a high pressure carbamate condenser and a reactor, and a recovery section, the method comprises installing an additional reactor between the recovery section and the high pressure carbamate condenser. The additional reactor is preferably installed in connection with an ejector, so as to allow ground placement of the additional reactor.
