Pumping Crude From a LACT Unitto a Pipeline
Pumping Crude From a LACT Unitto a Pipeline
(OP)
So there is a crude oil storage/stock tank. It feeds oil through a LACT Unit via the LACT Unit charge pump. A backpressure valve at the LACT Unit discharge holds approximately 35 psig backpressure on the LACT Unit. The crude discharge from the LACT Unit goes to a "PD" pump where it is then "injected" into a high-pressure oil pipeline at approximately 850 psig. I know there are literally 1000's of such oil lease installations like this all across West Texas. What type of pump setup are these guys using? (Just for grins, let's assume 350 gpm from the tank to the LACT charge pump.)
Thanks all.
Thanks all.

Used when selling product from a producer to a customer.

at 850psig pipeline pressure I am sure people are using everything from horizontal surface pumps to gear pumps. A PD pump is typically the preference, depending on pipeline pressure fluctuation for laterals. Progressing cavity pumps offer a PD design that limits pulsation, but I have not used one at pressures higher than 740psig. They also consume a lot of space. So long as your pipeline pump matches well with the system curve, you have many options. Where most of the problems arise is that the system curve is variable so people go with a PD capable of overcoming the range of discharge pressures. What is best and what is used are commonly two different things on these cash registers.
There are multiple companies that design successful LACT units. What works in West Texas, does not necessarily work everywhere else.

Thanks anyway.
