Pressure drop from distillation tower to compressor
Thread Content
The last edit to this post was made by Lihua Nan on 2012-1-1 at 14:58. The pressure drop from the distillation tower to the compressor has increased. Apart from blockages in the air coolers and scaling in the heat exchangers, with the feed composition remaining unchanged and the reaction pressure stable, another factor to consider is the internal leakage in the steam generator of the distillation slurry system; originally there were three such generators, but now only one is in operation. It’s necessary to analyze whether this has an impact. What level of pressure drop from the distillation tower to the compressor is considered appropriate? Please share the pressure drop values for your plants; ours is 79 KPA
We have experienced scaling in the oil and gas lines at the top of the tower
Our pressure drop is between 50 and 70.
It can’t be that high; ours is 30 kPa
Reply to 1# Cracking Man: Is it the filter at the rich gas inlet of the compressor that is clogged, or is it the filter at the gas outlet of the gas-liquid-oil three-phase separator?
