SPEC Energy DMCC to use Honeywell UOP technologies at grassroots refinery in Pakistan

Published by , Editorial Assistant
Hydrocarbon Engineering,

Honeywell has announced that SPEC Energy DMCC will use a range of Honeywell UOP process technologies at its refinery to convert low-value vacuum gas oil and vacuum residue into high-value products such as gasoline and alkylate.

Phase one of the project includes the installation of a new UOP Residue Fluidized Catalytic Cracking (RFCC) unit that is tailored to improve gasoline yield, and a UOP/Wood Solvent Deasphalting Process Unit (SDA) which will improve the feed quality to the RFCC. A UOP MeroxTM unit will also be installed to reduce the level of mercaptans in the LPG streams, in addition to a UOP InAlkTM process unit which will process the mixed C4 olefinic-rich stream from the Merox unit to produce alkylate, which is a high-octane blending feedstock for the gasoline pool. A UOP SelectFiningTM Process unit will be used to process the RFCC naphtha stream to meet the desired sulfur content.

“We are pleased to have selected UOP’s RFCC complex for our grassroots refinery,” said Zafar Sheikh, Group CEO of SPEC Energy DMCC. “We chose UOP’s RFCC complex over other RFCC complexes due to key technology advantages. Another key factor in the decision was the excellent technical support from UOP in identifying and selecting the most profitable configuration. This project will enable SPEC to increase gasoline yield and maintain a high margin, in line with our financial goals.”

The Honeywell UOP RFCC process utilises proprietary reactor technologies that are proven to minimise byproducts, increase gasoline yield, provide high feed flexibility and high reliability for processing residue feedstocks in the most economical manner. The catalyst regeneration will carried out by using UOP’s high-efficiency, combustor-style regenerator which uses a fast-fluidised combustion zone to achieve the best coke burning and full combustion of CO to CO2. A catalyst cooler will be added to remove variable heat from the regenerator, providing feed processing flexibility and the ability to adjust the catalyst-to-oil ratio for higher conversion and production of valuable steam from the RFCC unit.

UOP will provide technology licensing, design services, key equipment and catalysts and adsorbents for this project at the refinery in Pakistan. When completed, the total conversion capacity of the complex is expected to be 45 000 BPSD (or 6898 tpd), as a combination of vacuum gas oil and vacuum residue.

“These UOP technologies will allow SPEC Energy DMCC to boost production of high-octane gasoline blending feedstock at a grassroots refinery in Pakistan while benefiting from low capital and operating costs”, said Laura Leonard, Vice President and General Manager, UOP Process Technologies. “UOP continues to invest in its RFCC, Merox, InAlk, SDA and Selectfining technology development to meet the most ambitious needs of our customers. I’m proud that SPEC Energy DMCC elected to continue its success story with UOP RFCC technology.”
