Is there a problem with pressure fluctuations in the transport gas of Shell gasifier?

Thread Content

When Shell coal is used to produce methanol, when the system is normal, the pulverized coal transportation medium generally needs to be poured from nitrogen to carbon dioxide (carbon dioxide gas flashed by the low-temperature methanol washing device). However, as a gas consumption unit - gasification, the gas consumption is unstable, sometimes large and sometimes small. It can be simply said that when the 12 system is pressed, the gas consumption will increase, and vice versa. This will have a negative impact on the control of the compressor and the control of the low-temperature methanol washing flash steam. Does this situation exist in your organization? How do you do it in operation? Thanks for the discussion. This post was last posted by Tianya Wandering on 2009-3-8 10:23. The edited font size is default and segmented. ]

1. This phenomenon must exist 2. Control peak shifting to reduce fluctuations (related to load) 3. Compressor control is mainly based on stable volume, and automatic control is set to reduce the impact on methanol washing
