Modular refinery 10000 / 20000 bpd

20,000/10,000 BPD CRUDE TOPPING UNIT
Sell Energy if offering for sale a crude topping unit complete with all
equipment The attached equipment list gives the equipment included in the sale.
All equipment has been inspected, refurbished and certified. The plant does not have the
heater, piping, valves, field instruments and control system at this time. If the buyer wants, we
can provide these as well and also build it for the customer on customer provided site.
The topping unit was designed with one 20,000 bpd crude tower with two trains of exchangers,
and pumps, each having the capacity of 10,000 bpd. The plant operated the unit only at 10,000
bpd, therefore, the second train was never built. Current capacity of the topping unit is only
10,000 tpd.
All engineering documents are available.
The unit will produce naphtha, diesel and fuel oil. The quantity of each product and the quality
will depend on the crude used.
The unit can be skidded. The crude tower, however, will be field installed.
Give below is the process description and an equipment list is attached.
PROCESS DESCRIPTION
The Atmospheric crude unit is designed to process 20,000 bpd of API 35 to 37 gravity crude
with no more than 0.9% sulfur to produce naphtha, kerosene (jet fuel), diesel, atmospheric gas
oil and residue. Actual through put may vary depending on the gravity of the crude. The unit
is designed in such a way that it operate at 50% capacity.
The crude is heated from 80oF to 250oF by sending the crude through product exchangers before
it is sent to the deslater where the salt is removed from the crude by electstatic process. The
desalted crude is sent through additional heat exchangers and the crude temperature is raised to
411oF before entering heater.
In the heater, the crude is heated to 640oF and then the crude is sent to flash zone of the crude
tower. Here the crude is fractionated into off gas, naphtha, kerosene, diesel, AGO and resid.
Overhead vapors are cooled and partially condensed in the overhead heat exchanger and air
condenser. Overhead vapors flow to the caustic scrubber and then to the crude heater.
Naphtha is caustic washed and sent to storage. Kerosene and diesel draws are stem stripped with
150 psig steam while the AGO is not. Each stream is cooled with heat exchangers with crude
feed and additional fin-fan coolers and then sent to storage.
