Patent number: 10315925Abstract: The invention provides a method and a plant for producing urea ammonium nitrate (UAN). The method involves the use of a condensation section, optionally in combination with a medium pressure decomposition section, between the dissociation and neutralization sections. The invention further provides a method of modifying an existing UAN plant. The advantages of the process of the invention are that the emission of CO2 can be reduced, the plant capacity can be increased and the high capital expenditure needed for CO2 compression equipment is reduced.Type: GrantFiled: November 26, 2015Date of Patent: June 11, 2019Assignee: Stamicarbon B.V.Inventors: Johannes Henricus Mennen, Fredericus Henricus Maria Buitink, Willem Frederik Roos

Patent number: 9914107Abstract: 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.Type: GrantFiled: December 27, 2013Date of Patent: March 13, 2018Assignee: STAMICARBON B.V.Inventors: Fredericus Henricus Maria Buitink, Luc Louis Maria Dieltjens
