Discussion on production expansion of coal to methanol purification unit
As the original environmental protection process of the 600 000 t/a coal to methanol plant could not meet the requirements of the current standard,the purification unit was modified.Four different renovation plans were analyzed,and the capacity expansion of the purification system was determined as the main focus.Two specific renovation plans for purification capacity expansion using the semi lean liquid process were analyzed,and the plan B using a new methanol scrubber and ancillary equipment was determined.The operation results after the renovation showed that all performance indicators of the unit met the assessment requirements,the product output was increased by 10%compared with the original design,and the annual operating cost was saved by more than 20 million yuan.
