Abstract
The present invention provides a method for increasing the capacity of a urea production complex, the method comprising a step of adding to an existing urea production complex a COproduction unit, which unit employs a COproduction method comprising: i) subjecting a hydrocarbon feed to short contact time catalytic partial oxidation (SCT-CPO) to produce a first gas mixture comprising H, CO and CO, ii) subjecting said first gas mixture to a water gas shift reaction yielding a second gas mixture, iii) separating COfrom said second gas mixture yielding a purified COstream and a hydrogen containing stream and subsequently iv) reacting said purified COstream with ammonia from the ammonia production unit to produce urea. The invention also provides a urea production complex realized by the application of this method and a urea production method.
