Issue of using crude benzene to replenish newly washed oil
Thread Content
Does any friend working at a coking plant know that the crude benzene make-up oil is added to the system in front of the oil-poor pump?
As far as I know, in coking plants, oil is added before the rich-oil pump. I used to think that adding oil before the lean-oil pump had many advantages: the temperature of the rich oil is higher, which improves the efficiency of benzene washing and removal, and it also reduces the amount of cooling water needed for the lean oil. I would appreciate it if experienced professionals could give me some advice. Please contact me at QQ1429029938 or 15656101329 so we can exchange ideas regarding coal coking issues

We originally added it in front of the rich fuel pump, but later changed it to adding it in front of the lean fuel pump.
Reply to 4# “Avi” Why? What are your insights?
Our factory also makes supplements in front of the oil-rich pump
I believe that pre-fueling before the lean oil pump affects the rich oil preheating, thereby increasing the load on the tubular furnace
I think it is better to make up the amount in front of the oil-poor pump, as the newly added washing oil goes directly into the benzene washing tower, without reducing the efficiency of benzene washing.
Our factory adds it before the oil-poor pump
It is added directly to the lean oil tank; due to the certain temperature of this tank, it can also serve to remove water.
Our factory adds newly washed oil to the lean oil tank, and then uses a lean oil pump to send it into the system.
