How do you guys deal with slurry?
Thread Content
I would like to ask the experts here: how is the heavy fraction slurry produced by the refining unit handled? Now, a consumption tax is imposed; if the oil slurry is sold directly as fuel oil, the price obtained from sales is not even enough to cover the taxes. Are there any new uses that can reasonably circumvent this problem?
Those who know solutions, please share your advice!
If it has to be sold, what would be the best product to sell it as? Or where would it be most cost-effective to use it?
An appropriate amount of cracked light oil can be blended in to produce heavy petroleum fuel oil, which is used as fuel in various industrial furnaces or boilers.
The slurry is generated by the catalyst itself; the reprocessed oil slurry leads to a significant increase in coking in the unit, and it also tends to cause coking inside the settler
In that case, consumption tax still has to be paid, right?
The treatment methods I am aware of include sending it to coking units, transporting it away, or using it as fuel oil in thermal power plants or atmospheric/ vacuum distillation fuel boilers. What is the solid content in your oil slurry approximately?
Use it for coking; it’s best to have a sedimentation tank when the solid content is high, otherwise the coking furnace tubes won’t be able to handle it.
