(613c) Hydrogen Production Plant with Urea Co-Production

While fossil fuels have been very useful in shaping the industrial world as we know it today, their use has been very detrimental to the environment. Nowadays, there is a very strong outcry to move away from this conventional source of energy and revenue to cost ratio remains competitive with respect to gasoline and entice people into purchasing hydrogen vehicles.

In this work we present a hydrogen production process in which hydrogen and urea are generated, instead of the conventional hydrogen and carbon dioxide. The feed to the steam methane reformer (SMR) consists of water and natural gas mixed simultaneously in the appropriate ratio. The outlet of the SMR consists of synthesis gases which are used in the production of urea. In order to address and fulfill the energy requirements of the entire plant, heat and power integration techniques are applied into the process allowing us to maintain a self-powered process plant, reducing the carbon emissions to near zero and being economically feasible.
