AN IMPROVED PROCESS FOR SYNTHESIZING UREA WHEREIN THE EXPLOSIBILITY OF THE DISCHARGE GAS EXITING FROM THE REACTOR IS REDUCED

摘要

To reduce the tendency of a discharge gas from a urea-producing plant to explode, the discharge gas is mixed with one or more gas streams which are obtained from an ammonia- producing plant and whose composition is from 0.1 to 77% by volume of H2, from 0.1 to 29% by volume of N2, from 0.1 to 50% by volume of CO and/or CO2 and/or Ar and/or He, and a balance to 100% by volume of CH4.
