Petrochina Completes Phase I Expansion for Sour Crude Downstream Processing Project

---

Written by Faye Wang from Industrial Info Resources (Sugar Land, Texas)--Petrochina Guangxi Petrochemical Company (Guangxi Qinzhou, China) has completed the first phase of a sour crude oil downstream processing project at the company's 200,000-barrel-per-day (BBL/d) crude oil refinery at a cost of $1.27 billion. The project is designed to improve Petrochina Guangxi Petrochemical's ability to process high sulfur crude oil.

A series of units were added that will use hydrogenation to process high-sulfur Saudi light and intermediate mixed crude oil. The process route design is as follows: crude distillation, residual hydrotreater, residue fluid catalytic cracking, hydrocracker.

The project includes the addition of an 80,000-BBL/d residue hydrotreater unit; a 40,000-BBL/d diesel hydrotreater unit; a 20,000-BBL/d gasoline desulfurizer unit; a 16,000-BBL/d jet fuel hydrotreater unit; an 8,000-BBL/d light naphtha isomerization unit; a 260,000-ton-per-year sulfur recovery unit; a 140-cubic-meter-per-hour hydrogen unit; a 100,000-ton-per-year methyl tertiary butyl ether (MTBE) unit; a tank farm expansion; and the addition of public utilities and other auxiliary production facilities.

The gasoline desulfurizer unit was brought online November 15. The project will enable the refinery to produce Euro IV-standard gasoline.

The MTBE, light naphtha isomerization and jet fuel hydrotreater units were run successfully in the first week of December. The residue hydrotreater, diesel hydrotreater and sulfur recovery unit are scheduled to begin after the Chinese New Year holiday.

Petrochina Guangxi Petrochemical Company (Guangxi Qinzhou, China) is one of Petrochina Company Limited's (HK:0857 or SSE:601857) largest oil refiners with annual processing capacity of 200,000 BBL/d. The refinery is located in the Economic Development Zone, Qinzhou Port, Qinzhou City, near the south China sea.
