Saudi Polymers
Saudi Polymers is a joint venture limited liability company with a share capital of 4.800 Million Saudi Riyals and commercial registration number 2055008886 issued in Al-Jubail on 29/11/1428H, corresponding to 9/12/2007. In September 2003, Arabain Chevron Phillips (ACP) and SIIG, began development of the Saudi Polymer Project. The Project was originally named National Chevron Phillips Project (NCP). Saudi Polymers’ facilities will also be integrated with the existing Saudi Chevron Phillips (SCP) and Jubail Chevron Phillips (JCP) facilities to a certain degree in order to leverage capital and capture operating efficiencies. The following table summarizes the primary product mix and volume expected from Saudi Polymers: Saudi Polymers Ethylene 1-Hexene
Operating Volume KTA 1,165 100
Propylene HDPE / LDLPE PP PS
445 1,100 400 200
Project Description: The Saudi Polymers Project will utilize an ethane / propane steam cracker to process 60 million SCFD of ethane and 40 thousand barrels per day of propane. Of the 1220 KTA of ethylene to be produced from the cracker, 55 KTA will be consumed in the metathesis unit to produce propylene, netting 1,165 KTA of ethylene available for the derivative units. The derivative units will consist of 100 KTA of 1-hexene, 1,100 KTA of polyethylene (“PE”), 400 KTA of polypropylene (“PP”) and 200 KTA of polystyrene (“PS”). The PE unit will consist of two plants. Each plant will produce 550 KTA of high density polyethylene (“HDPE”), while one of the plants will have the ability to also produce low density linear polyethylene (“LDLPE”). The PP unit will be capable of producing homopolymer and copolymer resins. It will also consume the majority of the propylene from the ethylene and metathesis units. The PS unit will be capable of producing general purpose polystyrene (“GPPS”) as well as high impact polystyrene (“HIPS”). The styrene feedstock for the PS unit will be purchased from JCP. The SCP, JCP and Saudi Polymers facilities will be operating as integrated units, to ensure an efficient, low cost manufacturing operation capable of competing in world markets and providing the foundation for future capital investments. Even though any of the three projects, SCP, JCP and Saudi Polymers, could stand on its own in terms of feedstock supply and product marketing, the relative economics are enhanced via operational and common facilities integration. A summary diagram depicting the integration of SCP, JCP and the Saudi Polymers Project is shown below:

Products and Applications: High Density Polyethylene (HDPE) The market for HDPE can be divided into eight application areas: film, fiber, blow molding, injection molding, pipe and conduit, rotomolding, other extrusion, and miscellaneous applications. HDPE is stiffer than the other polyethylenes, and thus is primarily used in molding applications, which account for approximately half of the global HDPE market. Blow molding applications include storage tanks, containers and drums, technical applications in fuel tanks for the automotive sector, as well as intermediate bulk containers. Injection molding applications cover a wide range of consumer articles and household items. Polypropylene (PP) Polypropylene is one of the plastic industry’s most versatile, low-cost polymers. PP is achieving a portion of its demand growth by displacing other polymers. This has been especially true for such applications as polystyrene in disposable utensils, sheet extrusion/thermoforming in soda straws. Its higher heat resistance has gained limited acceptance in microwave food packaging and dishwasher safe products. Polystyrene (PS) PS is a versatile polymer that is used in applications ranging from disposable packaging to housings for electronic appliances. There are two main types, known as general purpose polystyrene (“GPPS”) and highimpact polystyrene (“HIPS”). GPPS is the more widely used of the two, generally favored for its ease of processing, and used in a very wide range of generally low- specification applications. HIPS contains a small proportion of polybutadiene, which is a type of synthetic rubber, and improves the strength and impact resistance of the resin. HIPS is used for housings of computer monitors, televisions, etc. 1-Hexene. 1-Hexene is a comonomer utilized in the production of polyethylene to improve product quality. The 1-Hexene market is dominated by polyethylene production which accounts for close to 90% of its demand; this is focused mainly on LDLPE. Other applications, including plasticizers, are forecast to grow at a lower rate than polyethylene. Consequently, polyethylene growth will continue to be the driver behind 1-hexene growth. 1-Hexene based polyethylene is a high performance grade of polyethylene, with production dominant in North America. Production of 1-Hexene grade polyethylenes is expected to grow in the Middle East and Asia.
