Crude oil stabilization process: the products are light hydrocarbons and heavy hydrocarbons. Is the stripping process useful?
Thread Content
The temperature at the outlet of the heater is 220°C; the feed to the primary stabilizer tower is at multiple levels of 200°C, while the temperature at the top of the tower is 140°C. The moisture present at the top of the tower is sent to a shallow cooling unit for the recovery of light hydrocarbons, after which the resulting dry gas is returned to be used as fuel in the heater. From what I’ve read, it is said that increasing the gas stripping process can boost production and reduce the temperature at the heater’s outlet, thereby saving resources. However, most studies mention a tower inlet temperature of around 100 degrees, and the product obtained is only light hydrocarbons. I would like to ask whether it is feasible to use stripping in my facility
For the light components at the top of the tower, we currently use air cooling and water cooling; followed by three-phase separation in the reflux tank. The light hydrocarbons from this tank are either sent outside or used for reflux. The gas then goes to the shallow cooling unit, and the resulting dry gas is used as fuel in the heating furnace. I’m considering feeding some of this dry gas back into the tower – I’m not sure if that will be effective; I’ve seen articles discussing this approach. Please, expert, help me out!
In the crude oil stabilization process, increasing gas stripping can boost production.
But many people say that in processes using gas, reflux is not usually applied. Why is that? Currently, we need to use reflux
With the help of kind people, I wonder why, with the use of the stripping process, backflow is required very rarely. Our products are light hydrocarbons and heavy hydrocarbons, so backflow is necessary; does that mean we can no longer use stripping?
