Seeking help with low-temperature methanol washing
Thread Content
Hello everyone. Our company currently uses two towers for the low-temperature methanol washing process to absorb different feed gases; the volume of these feed gases is roughly the same, but only one system is used for absorption. I would like to ask: what is the minimum production capacity possible for this low-temperature methanol washing process? Can it operate at 20% capacity? Secondly, since our company uses a two-tower absorption system combined with one recovery system, should our load be calculated based on the total load of the absorption towers or that of the recovery system? After all, we are currently operating only one absorption tower.
The above is incorrect; it’s a separate set for the recycling system
Two absorption towers and one recovery system
The minimum production load for low-temperature methanol washing can reach 30%
Actual production situation: Our plant produces synthetic ammonia and methanol simultaneously along with urea; it operates normally at a minimum load of 27%； The load calculation has been performed on an aggregate basis: both the ammonia synthesis scrubber and the methanol scrubber were operated at a minimum of 10% each
How is the 30% load determined? Thank you
So, what you mean is that the load is determined based on the total amount of feed gas, in other words, the load is still determined by recovery. I mean, what if I only run one tower?
30% of the normal volume, that is, 30% load
