Abstract: 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.
