Destination of oil recovered through back-extraction in deep desulfurization of liquefied gas
Thread Content
For the deep desulfurization of our liquefied gas, we use the process package provided by Hebei ** Company; this process includes a step for back-extraction of the disulfides generated during oil absorption. The oil obtained from this back-extraction is sent to the fractionation tower. Where do you send yours?

We’re going to the feed tank of the diesel and gasoline hydrogenation unit.
Do you use a large amount? Is the quantity taken from the tank area too small? Could there be a problem with condensation lines in winter?
About 1–1.5 tons per hour. In winter here, the temperature drops to well below zero degrees; I’ve heard of no issues with freezing. Gasoline is used, and the material goes to the feed storage tank of the hydrogenation unit; the two units aren’t very far apart. It’s not a device under my responsibility; if necessary, I’ll go and look into it carefully.
Thank you, it’s enough to know where it is; there’s no need to know too many details
Freezing may occur. It is possible to contain alkaline liquid. For back-extraction, do you use gasoline or diesel?
It is designed to use stable gasoline; I’ve never heard of it being used with diesel
Theoretically, diesel can be used, as well as the principle of similarity and compatibility, but in most cases gasoline is used, with the extracted oil being poured into the crude gasoline tank
Are there many devices that use diesel? As far as I know, none of the devices in use currently rely on diesel
Have check valves been installed on your anti-extraction oil extraction device and the self-circulating pipelines?
