| titleOfInvention | A kind of exhaust gas recovery system and technique stablizing coproduction for tripolycyanamide and carbamide |
| abstract | The invention discloses a kind of exhaust gas recovery system stablizing coproduction for tripolycyanamide and carbamide, and use this exhaust gas recovery system to carry out tripolycyanamide and the technique that coproduction stablized by carbamide.Press decomposition tower and two-stage nitration decomposition tower to carry out two sections of decomposition in being used by the urea synthesis reaction liquid exported from crude urine element synthetic tower, make the urine that mass concentration is 60 80%, deliver to former vapo(u)rization system；Tripolycyanamide synthesis tail gas is made, through two sections of condensed absorbent, the dense methylamine liquid that concentration is 60 80% and returns the recycling of former high-pressure system.The technique using the present invention, avoid the adverse effect that former stripper load increase is brought, former urea plant is made to produce and operate more stable, connect the urea plant total productive capacity in puerperal with tripolycyanamide and add about 12.3% than originally, and the load of stripper, rectifying column, low pressure carbamate condenser is with the most basically identical. |
