Basic Design of Process Units at Negin Makran Petro-Refinery

The Negin Makran Petro-Refinery, owned by Shastan Commercial Investment Company, has a refining capacity of 300,000 barrels of crude oil per day and is located on the coast of the Persian Gulf. The refinery produces 18 different products, including fuel and petrochemical products, in accordance with the latest global standards. Of the crude oil, 35% is converted into petrochemical products, while 65% is converted into fuel products. It is expected that Phase 1 of the “Negin Makran Refinery” project will be operational in 1405 (2026), and Phase 2 will be operational in 1407 (2028).

This project is located on an 800-hectare site in Bandar Abbas, which includes numerous process and utility units, as well as storage tanks for feedstock and products.

The front-end engineering design (FEED) for the following process units: Sulfur Recovery Unit (SRU), Needle Coke Production (NCSDA – NCU), LPG Treatment (ULPG), Propylene Recovery (PRU), Ethylbenzene Production (EB), and Styrene Production, is being carried out by this company (ITM).

The basic design (Basic Design) as well as the front-end engineering design (FEED) for the process units, including Sulfur Recovery Unit (SRU), Needle Coke Production (NCSDA, NCU), LPG Treatment (ULPG), and Propylene Recovery (PRU), are the responsibility of this company (ITM).

Sulfur Recovery Unit (SRU)

The goal of this unit is to recover sulfur compounds present in crude oil and prevent them from being released into the environment. The total capacity of the unit is 900 tons of solid sulfur per day. This unit has the ability to recover sulfur compounds at a rate of 99.9%, preventing sulfur compounds from entering the environment.

Needle Coke Production Unit (NCSDA, NCU)

The goal of this unit is to produce 360 tons of needle coke per day. This highly versatile product is essential for various industries. The primary use of needle coke is in the production of graphite electrodes for the steel industry.

LPG Refining Unit (ULPG)

The goal of this unit is to refine 554 tons per day of fuel gas output from the RFCC unit for use within the refinery. Additionally, this unit refines 2,820 tons per day of LPG output from the RFCC unit. The refining process aims to reduce sulfur compounds and make this product suitable for propylene recovery.

Propylene Recovery Unit (PRU)

The goal of this unit is to recover 870 tons per day of propylene for use in the polypropylene unit.
