Condensate generation are normally 15-17% of FFB. So for 60mt/hr oil mill condensation generated every hour are about 19.5mt.
Formula to calculate % of dilution are as followings.
A) % dilution = hot water / diluted crude oil.
B) % dilution = hot water / crude oil.
So for 60mt/hr oil mill with 25% of dilution require 10.5mt/hr hot water for dilution. If we are using condensate as dilution we should able to reduce water consumption by 10.5 mt / hr.
1. Condensate from sterilizer will be pump to vibrating screen or stationery screen and been stored at a holding tank.
2. From holding tank. Condensate will be pumped to dilution tank and heeted to 90d c. Overflow of dilution tank will return back to sludge tank.
3. A float valve shall be installet at dilution tank as backup supply in event of less condensate supply.
4. In Evans condensate supply are not sufficient, float valve will allow frash water as make up.
With this, we will able to reduce water usage by 9.0 metre cube / hr.
In terms of oil recovers efficiency also shown improvement due to reduce of mass at downstream.
