Project Objectives

• The project aims to eliminate environmental pollutants in line with national and regional environmental commitments, improve refinery efficiency, and increase annual revenues. Executed under an EPCC contract, the project includes the construction of a Light Naphtha Hydrotreating Unit for sulfur removal from naphtha feed, a Benzene Reduction Unit to remove benzene from process feeds, a Hydrogen Production Unit to supply hydrogen for refining operations, Sulfur Recovery Units and associated treatment facilities for processing sour gases generated by other refinery units, as well as the production of diesel fuel compliant with international quality standards. Then the project comprises the construction of LNHT, BRU, GHT, HPU, SRU, AMN, SWS, TGT, and all required utility units.

Project Objectives

• To develop a 120,000 barrels-per-day refinery complex in Gachsaran, comprising all core processing units and supporting infrastructure required for safe and efficient operations.

Value Statement

• The Gachsaran Refinery Project represents a major downstream investment, designed to enhance regional refining capacity and strengthen Iran’s domestic fuel supply chain through modern EPC delivery.

Scope of Work

• Engineering, procurement, construction, and commissioning.

Project Objectives

• Tabriz Oil Refining Company intends to complete and upgrade its existing isomerization unit. The unit processes hydrotreated light naphtha with a capacity of 12,530 barrels per day. Its primary objective is to increase the octane number of the feedstock and thereby enhance the quality of the final gasoline product. The feed stream, primarily consisting of pentanes and hexanes, is subjected to an isomerization process to increase its octane value. The upgraded unit will incorporate new distillation columns and optimize the isomerization process to improve gasoline octane rating and ensure compliance with fuel quality standards, including low sulfur, aromatics, and olefins content.
