The bidding for the 4th aromatic complex is in final stage and contract for this giant project will be awarded in the near future.
This complex will produce 740,000-t/y paraxylene, 420,000-t/y benzene and 100,000-t/y orthoxylene.
Japanese, Korean, European and Iranian companies took part in the bidding. The scope of work for this complex includes grant of license, basic & detailed engineering,
supply of equipment & material, technical assistance during construction and start-up and provision of finance. The 4th aromatic complex is one of
the third phase projects of the NPC's five-phase development program. The project will be built at Pars Special Economic/Energy Zone (also known as Assaluyeh) on the northern
coast of the Persian Gulf. The zone will be developed in conjunction with the South Pars gas field, which will supply feedstock for the complex.
NPC has decided to extend the bidding deadline for the 9th olefin complex to the end of March 2000 due to changes in the production capacity
of the ethylene plant and its downstream units.
Petrochemical Special Economic Zone (Petzone) embarked on building a dual-purpose export jetty
|
The Petrochemical Special Economic Zone (Petzone) is the scene of an ongoing effort to achieve the ambitious yet realizable goal of developing the Iranian petrochemical industry.
Lying on the northwestern coast of the Persian Gulf, where Iran's rich oil and gas fields are located, the Petzone will become the hub of the country's petrochemical industry once NPC's development projects come on stream.
Ten petrochemical projects, mostly world-scale, have been formulated to be constructed at the Petzone. The projects, which are targeted to become operational by 2001, are basically export-oriented.
To facilitate the export of products manufactured by these projects, the Zone has started to construct a dual-purpose jetty at the nearby Khur Musa estuary.
|
The Petzone has begun building a dual-purpose jetty at Khur Musa estuary, on the northwest of the Persian Gulf.
The jetty is designed to consist of two separate terminals for the export of solid and liquid products. The liquid products include heavy cuts, benzene, aromatics, liquid epoxy resins, C5+, diethylene glycol, butadiene, propylene, C4, propane, butane, pentane, HDPE, LLDPE.
The solid products include polycarbonates, solid epoxy resins, PET (bottle and fiber grades), HDPE and LLDPE.
The capacity of the liquid-products terminal is 3.5 million tons per year and ships up to 70,000 tons of deadweight can be berthed at it. It is a dolphin terminal equipped with four mooring dolphins which will be connected together with walkways and roads. An Iranian contractor has already started constructing this terminal.
The capacity of the solid-products terminal is 2 million tons per year. The second-generation of container-carrier ships can be berthed at this terminal which is presently at the design stage.
Located on the northwestern coast of the Persian Gulf, the Petzone is linked to the international waters via the Khur Musa estuary.
In the near future, NPC will invite international engineering companies to tender for a 1,800-t/d urea granulation project in lieu of a previously proposed prill urea project at Razi Petrochemical Company, southwest of Iran.
The scope of work for this project will encompass detailed and basic engineering plus supply of equipment/material, erection and construction.
NPC will soon issue tender documents for the technology and basic engineering for a21,500-t/y phthalic anhydride (PA) plant and 40,000-t/y deocthyle phethalate (DOP). The PA/DOP plant will be located in the vicinity of Esfahan Petrochemical Company, in the central province of Esfahan
Bids by Iranian engineering companies for the conceptual design of a centralized utilities plant at Pars Special Economic/Energy Zone (also known as Assaluyeh) are under consideration and NPC will soon award the contract.
A special committee, named Field Control System (FCS), has recently been set up in NPC to study and coordinate the use of the state of the art technology for plant control. The committee has already decided to use the technology in some of NPC's development projects.
The idea of utilizing a new technology that allows all-digital, two-way communication system interconnecting measurement and control equipment, first came into being in 1996 when Bandar Imam Petrochemical Company (BIPC), a subsidiary of NPC, conducted a study for modernizing its plant and process control systems. The study aimed at examining systems available in the international markets and recommending an economical and effective system that could provide device interoperability, better field-level control and reduced installation costs. Weighing its merits and demerits, the study recommended the fieldbus technology.
The findings of the study prompted NPC managers to set up a committee to lead and adopt policies for using the technology in the company's development projects presently under construction.
The FCS Committee provides consultancy services to the managers of NPC projects over the use of the technology. It also compiles FCS characteristics, reviews and studies issues related to the use of the technology and its role in increasing productivity.
The distillation tower of an MTBE project was designed and built by Iranian companies. The tower was designed by Petrochemical Industries Design and Engineering Company (PIDEC), and fabricated by Azar Ab and Reactor Sazan companies. It was built in seven separate pieces for ease of transportation. Azar Ab Company built the first piece while Reactor Sazan Company built the remaining six. The two companies will also fabricate the plant's pressure vessels.
The 86m tower, which weighs 520 tons, separates isobutane from mix butane. It is the first time that such equipment is built in Iran.
Located at the battery limit of Bandar Imam Petrochemical Complex (BIPC), the 500 thousand-t/y MTBE project is an NPC's development project. It will use butane and methanol as its feedstock which will be supplied by BIPC and Kharg Island Methanol Plant respectively. The basic and detailed engineering for the project were both provided by PIDEC.
Razi Petrochemical Company (RPC) will carry out 10 projects in a bid to run its plants at full capacity, raise the quality of its products and generate more export revenues.
The projects include sulfur granulation, improvement of loading facilities, renovation of an ammonia plant, optimization of power generation and supply, maintenance of a sour gas pipeline, and installation of wellhead equipment at Masjid-e-Soleiman wells, which supply the complex's feed.
RPC, one of NPC's oldest complexes, was constructed in 1966 based on a 50-50 joint venture with Allied Chemical of America. It produces ammonia, urea and diammonium phosphate (DAP) with an annual capacity of over 1.8 million tons. It also produces phosphoric acid, sulfur and sulfuric acid. The complex's overall annual capacity is in excess of 3.2 million tons.
The ethanolamine plant of Arak Petrochemical Company (ARPC), one of NPC's subsidiaries, came on stream on February 5, 2000. The plant overall capacity is 30,000-t/y with a breakdown of 10,000-t/y of mono-, 12,000-t/y of di-, and 8,000-t/y of triethanolamine. It consumes 26,000-t/y of ethylene oxide and 5,100-t/y of ammonia as its feedstock. The contracts for technology and basic engineering for the plant had been awarded to Oxiteno of Brazil while the Iranian company Nargan provided the detailed engineering and procurement services. A number of other Iranian companies had also been involved in the plant construction as well as in manufacturing some of the equipment and machinery.
ARPC's ethanolamine plant is the last link in the complex production chain. It produces rubber and plastics, polymers, basic chemicals and pesticides. The complex overall capacity is over one million ton per year.
Ethanolamines are used for scrubbing acid gases, especially in synthesis of ammonia from gas streams; nonionic detergents used in dry-cleaning, wool treatment, emulsion paints, polishers, agricultural sprays; chemical intermediates; pharmaceuticals; corrosion inhibitors and rubber accelerators.
