Abstract
Process 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 removal from flue gas from reforming section to convert partially or fully all ammonia into urea. Synergi of having methanol, ammonia and urea production to produce coating material for the urea production.
