Abstract: A process and plant for the co-production of methanol and ammonia together with urea production from a hydrocarbon feed without venting to the atmosphere carbon dioxide captured from the methanol or ammonia synthesis gas and without using expensive air separation units and water gas shift. Carbon dioxide is removed from flue gas from reforming section and used to convert partially or fully all ammonia into urea.
