Abstract: The process flow and actual operation of the syngas compressor in the Shell pulverized coal gasification to methanol technology are introduced in this paper. Targeting at the obvious vibration of the coal to methanol syngas compressor during  re-start-up after maintenance,  this paper gives an analyzation of possible technology and equipment problems existing in the maintenance and start-up of the compressor. After shut-down for maintenance, practice shows that by strengthening process management and improving the quality of maintenance, the safe operation duration and quality of the compressor are largely improved.
