A summary of operations in manufacturing units of BSPC:
The feeds for this unit include pyrolysis gasoline, provided by Amir Kabir Petrochemical Company and Marun Petrochemical Complex, and hydrogen, provided by the Aromatic Unit of BSPC. This unit engages in hydrogenating pyrolysis gasoline in order to produce pentane cut (C5 cut), heavy end, and HPG (Reformate).
Unit 100 consists of a furnace, two compressors, three catalysis reactors, and three distillation towers. Since the feed for this unit is provided by 2 adjacent petrochemical companies and its operations are of high sensitivity, there is a need for intensive operational care and control in this unit.
Unit 100 annually consumes 139,000 tons of feed and produces 106,000 tons of refined pyrolysis gasoline, 11,000 tons of heavy end, and 210,000 tons of pentane cut (C5 cut).
Unit 200 consumes the naphtha provided from the Pazanan oil field as the feed and produces 3 products that are used as the feed for Unit 300.
Possessing two furnaces and two distillation towers, Unit 200 produces light end as the feed for Amir Kabir Petrochemical Company, heavy end for export, and heart cut as the feed for Unit 300.
Quality control of ingredients of light end, heavy end, and heart cut will improve the conditions in all downstream units. Unit 200 annually consumes 1,720,000 tons of feed and produces 880,000 tons of heart cut, 488,000 tons of light end, and 350,000 tons of heavy end.
Unit 300 receives heart cut as the feed from Unit 200 and provides the purified feed for the aromatic unit by performing catalytic reactions on heart cut in the presence of hydrogen.
Unit 300 includes two parts of catalysis and distillation and consists of a distillation tower, two furnaces, a reactor, and two compressors.
In this unit, nitrogen sulfur compounds and water are purified and separated from naphtha and then they are prepared for the production of aromatics. This unit annually consumes 880,000 tons of feed and produces 878,000 tons of refined naphtha. This product, which is free of sulfur, iron, molybdenum, etc., is stored in a TK-3001 Tank.
The objective of Unit 400 is to produce Aromizate from HTN provided by Unit 300 stored in the TK-3001 Tank. The reactions producing Aromizate from HTN are performed at high temperatures (about 500°C) and very low pressures (less than 5 bar) in the presence of a metal-based catalyst in a hydrogen environment.
The design capacity of HTN received from Unit 400 is 877,877 tons per year (330 days per year) and the design capacity of Aromizate is 807,998 tons per year (including 76.1% aromatics) at the beginning of the catalyst lifespan (SOL) and 796,998 tons per year (including 75.7% aromatics) at the end of the catalyst lifespan (EOL).
The objective of Unit 450 is to continuously reduce the catalyst in the following steps:
- Coke burning
- Catalyst oxychlorination (oxidation of platinum and regulation of chlorine content)
- Catalyst calcination (removal of excess moisture from catalyst)
- Platinum reduction
The first three operations are performed in the reduction reactor (R-4501) and the fourth is performed in the D-4501 drum.
Unit 500 is an extractive distillation system for the initial separation and CLAY treatment of products. The total annual feed of this unit is 968,899 tons that include Aromizate (about 90%), which is provided by Unit 400, and HPY (about 10%), which is obtained from Unit 100.
Unit 500 consists of the following parts, which include several tanks for storing feed and products:
- de-heptanizer columns
- Clay treater
- Extractive distillation
- Stripper
- Solvent reduction
- Vacuum
Unit 600 consists of the following sections:
- BT Splitter
- C7/C8 Splitter
- C9/C10 Splitter
In this unit, benzene and toluene are separated after the clay treatment in BT Splitter.
Pure benzene is sent to the Battery limits as the final product.
More operations are performed on toluene in Unit 700.
C7/C8 Splitter separates the benzene/toluene mixture from C6 + aromatics produced through transalkylation.
C8+ aromatics are sent to the xylene isomerization unit and BT is transferred to the BT Splitter tower.
In the C9/C10 Splitter tower, C9 aromatics are separated from heavy aromatics; C9 aromatics are sent to the transalkylation unit and heavy aromatics are transferred to the Battery limits.
