Cause DPG product ammonia to consume high principal element and have following five aspects:
1, main body workshop is emptying: in DPG production process, feed intake, be oxidized, wash, mother liquor holding tank is emptying processes through south, workshop one-level spray absorber, but absorb thorough, produce peculiar smell, cause significant loss.
2, rinse dehydration post: DPG rinse dehydration post, in order to reduce discharge of wastewater, reduce water of productive use amount, 3-4 time is carried out in washing, and washing is thorough not, causes work in-process to contain a large amount of raw materials ammonia, produces peculiar smell, affects healthy.
3, distill post: in DPG ammonia still process post, because condenser heat interchanging area is little, chilled brine is not enough, causes ammonia temperature higher, and a large amount of ammonia overflows, and the ammonia of spilling lacks effective absorption, produces serious ammonia taste.
4, main body workshop pipeline: the ammonia that main body workshop internal oxidition post stills for air blowing and stock kettle are got rid of can not fully absorb.
5, chilled brine supply: frozen cooling water is not enough, can not meet the needs of workshop ammonia still process, CA synthesis backflow and tail gas absorption far away, cause the raw material that reclaim to enter in air, cause peculiar smell, unhealthful, wastes raw material.
