A question I don’t understand
Thread Content
Does anyone know that from the slurry cooling tank, there is a pipeline leading to the inlet of the crude oil pump – what is the purpose of that? Our crude oil pump is used to draw crude oil from the tank farm.
There isn’t a dedicated process for reprocessing oil slurry.
Could it be that starting up or shutting down the system is used for oil recovery, with the aim of reducing the discharge of slurry and sending it back to the oil storage tanks?
We also have this process for starting up the circulation line. The pipelines already have the labels applied; at the start of operation, crude oil is fed back in, and there is circulation in the distillation and other related lines
I’ve never seen it, but I think it’s used for raising the temperature in a closed-loop system during operation
Haven’t seen it! ! ! ! ! ! ! 11
It should be set up for reuse at the start of operation.
It is used to establish slurry circulation at the start of operation.
It operates in a closed-loop system; we don’t feed it through a raw material pump, but rather the slurry flows directly back into the raw material buffer tank
A closed-loop system for raw material circulation is established: the oil pump sends the oil back to the re-refining tank, from where it enters the fractional distillation column; after that, it is sent to the slurry cooler via a slurry pump before returning to the raw oil pump, thus completing the cycle.
We call this process here a “open-loop large cycle””
It was created at the start of operations for three-way circulation; with that crossing line in place, a closed loop is formed. Otherwise, if it’s open-circuited, oil will have to be continuously drawn from the tank area, which is very troublesome.
