Mixing Condensate with Crude Oil in a Storage Tank
Mixing Condensate with Crude Oil in a Storage Tank
(OP)
Hello All;
If any one can help me it will be great, we used the flared gas to produce electricity and condensate, on another hand the normal operation of the crude oil is to be stored in a storage tanks then shipped in a 10" pipeline for about 70 km to another facility to be treated there by heating and fresh water mixing.
The condensate production quantity is 10 tons/day, and produced with pressure of 170 psi.
My question is could I ship the produced condensate into the un-pressurized storage tanks to be shipped together with the crude oil or this will lead to condensate evaporation, and if it will not evaporate in this stage, will it evaporate in the end point during treatment with heating?
Best regards,
Amr Helaly Mohamed

This could also be quite hazardous for the downstream storage tanks, if pressurized condensate is let down to atmospheric conditions.

In addition to that, the quantity of the condensate is 10 ton and will go into the tank which should contain at least 1000 ton of crude oil, does it still hazard.

What is virtually impossible to predict under real conditions, is the degree of mixing inside the tank where Condensate is introduced into crude oil - this is not only a question of thermodynamic equilibrium but also of kinetics of the mixing process - depending on the incoming flowrate, mass of crude oil in the tank, process and ambient temperatures etc. - and these are all varying factors. You may encounter a "bullet" of condensate that will lift the emergency hatch off the tanks, and that can escalate to many unwanted scenarios.

First: It's dangerous as hell.
Second: Maybe illegal
Third: Figure you're going to lose most of it to boiloff anyway.

If the condensate is very volatile (say TVP at 100degF >20psia), it could blow the roof off your crude storage tanks.

All the methane, ethane, propane and butane will turn to gas and go out of the vent of the storage tank.
Think of a can of coke. What you have at 170 psi is a warm can of coke/pepsi which has been vigourously shaken. When you open the can to mix it with something, you won't have much left.....
