Regarding aromatic extraction vacuum pumps.
Thread Content
For a 60wt/year aromatic extraction unit, should the Edward EDP250 dry vacuum pump be used? Will it meet the production requirements? Those with relevant experience, please offer some guidance. Thank you!
This needs to be calculated; it’s best to consult with the design team
Domestic products are excellent; why use imported ones?
What domestic brand is it? How long has it been in use?
A dry vacuum pump with a capacity of 200 liters per second should be able to handle this, and it can also help address issues related to energy conservation and environmental protection
It is best to use water ring vacuum pumps from major manufacturers, as they have a low failure rate
Our dry screw vacuum pumps have been used in the aromatic extraction industry of Sinopec; careful consideration is required when selecting such equipment. Generally, the air extraction rate required for this process is 300 m3/h, but this value can vary depending on the specific process.

My facility has a design capacity of 800,000 tons per year, and I’m using an EDP250 from EDWARDS (it’s not Edwards Inc.; it’s Edwards, haha). The actual processing rate at present is 108 t/h. This dry vacuum pump, which doesn’t have a backup pump, has been in use for several years without any repairs.
The EDP pump is a bit of a gimmick; it’s not that useful in reality. The aromatic extraction process has been in operation for only a short time; there’s no need to use something so expensive. Moreover, the on-site application performance is not good. When the back pressure is low and the inlet flow rate is high, the temperature rise is very high, reaching 150°C at the outlet.
