30,000 bpd Capacity Modified Modular Refinery Operations in Nigeria ()
ABSTRACT
The study investigated and classified twenty Nigerian crude oil types
based on their products recovery volume at true boiling point temperature of
370˚C using crude oil assay analysis data into Group A (crude oil with recovery
volume above 80%), Group B (crude oil with recovery volume between 70% and 79%)
and Group C (crude oil with recovery volume below 70%) respectively. Thus,
twenty Nigerian crude oil types were simulated in a modified modular refinery
(modified topping plant) of 30,000 bpd capacity and twenty-nine (29) column trays number using Aspen Hysys
software. Furthermore, the residues from the conventional modular refinery were
processed as feedstock or precursor into the hydrocracker reactor attached to
the stripping section of the modified modular refinery to yield more valuable
products of liquefied petroleum gas, naphtha, diesel and bottom (residue). The
simulation results of the modified modular refinery were compared with conventional modular refinery in
terms of their residual yield percentage as Nigerian Brass 2012 of API 40.62,
recovery volume 88.78%, yielded residue of 11.22% and 1.29% for conventional
modular and modified modular refineries respectively while Okoro 2012 of least
API 23.54, recovery volume 57.84%, yielded residue of 42.16% and 4.92% for
conventional modular and modified modular refineries respectively. Thus, the residual
or bottom product issue associated with operational process of conventional
modular refinery operations in Nigeria due to inefficient or non-operational
conventional major refinery in Nigeria has been resolved to minimum or least
amount with the operational process of modified modular refinery operations in
Nigeria.
