Problems and transformation measures during the operation of deacidification and deamination towers
Yili Xintian Coal Chemical Co.,Ltd.'s coal to natural gas project uses a crushed coal pressurized gasifier for the gas production unit,and phenol and ammonia recovery technology for wastewater treatment.The deacidification tower and deamination tower of the phenol ammonia recovery unit have been running for a period of time,resulting in poor heat exchange and cooling effects,and process parameters deviating from the normal control range.By adopting alkaline cleaning measures for the deacidification tower and deamination tower,the operation effect is good after the transformation.
