It consists of a reduc- tion boiler, substituting for process three's reduction furnace, in which a high temperature reducing (less than stoichiometric air) converts the high nitrogen crude into H2, H20, C02, and CO which limits the formation of NO and reduces any formed NO into N2, a smaller quench section than process three which cools the

The sludge was fed into the first reactor (A) and for diluting the sludge, some water was added (20%). In the next reactor, the superheated steam raised the temperature of the sludge (190 °C).
