| Abstract: | Based on the rigorous thermodynamic model, the equilibrium stage models of two low parts of high pressure scrubber which are connected by steams are proposed separately. Resolving the two models′ calculafion can finish simulation of high pressure scrubber.The results are agreed well with the design data.Aimed at high nonidea and mathematical model characteristic of this system,a feasible algorithm is proposed. It is steady and convergence well. This work is significant for the optimization of the unit operation and equipment design. |
| Keywords: | high pressure scrubber equilibrium stage model urea process NH 3 CO H 2O urea system |
