The Liwa Plastics Industries Complex (LPIC) located at the Sohar Industrial Port includes:

• Steam cracker unit
• HDPE Plant
• LLDPE Plant
• Polypropylene Plant

The LPIC plant introduces production levels of about 880 KTA of Luban PE to serve local and international markets. This capacity includes the production of 440 KTA of Luban HDPE and 440 KTA of Luban LLDPE. In addition, LPIC’s 300 KTA of Luban PP increases OQ’s present PP capacity from 340 KTA to 640 KTA.

Mar 2021: CTCI Corporation and CB&I (which later merged into McDermott International) formed a joint-venture, or CCJV, in 2015 to carry out one of the four EPC projects on the complex, or LPIC EPC1-870 KTA Steam Cracker Project. Scope of work included steam cracking units for the main process, pygas unit, MTBE unit, API tank, sphere tank, bullet tank, desalination, wastewater treatment, spent caustic treatment, and incinerator. Lummus-licensed technologies was used for the ethylene cracking process. (Source)

16^th Jul 2014: ORPIC previously awarded contracts to CB&I for its ethylene technology and front-end engineering and design services at LPP, under which CB&I will deliver FEED services for the grassroots 800,000-tpy ethylene plant, a pygas unit, a MTBE and butene-1 unit, two polymer plants, a gas plant and pipeline, as well as related offsites and utilities.

At full capacity the project will add 838,000t/yr of polyethylene (PE) and about 215,000t/yr of polypropylene (PP), raising total production of both products in the country to 1.4mn t/yr from around 1mn t/yr, al-Shanfari said. The steam cracker allowed for the production of PE for the first time in Oman after the 880,000 t/yr swing PE plant started up in May last year. It also includes a 300,000 t/yr PP unit. (source)

The purpose of Liwa Plastics Project wasis to increase the production of plastics will from 200,000 tonnes per year (t/y) to 1.4 million t/y.
The Sohar refinery was previously treating 116,000 barrels per day (b/d) of crude oil with propylene output 40% too short to feed the current polypropylene unit. With the Sohar Refinery Improvement Project, the refinery capacity increased to 176,000 b/d in order to produce more transportation fuels and to increase the feedstock available for the Liwa Plastics project. RPIC adopted the mixed steam cracker technology in order to accept ethane, natural gas liquids (NGL), mixed liquid petroleum gas (LPG) and other condensate as feedstock (supplied by OGC's LPG and NGL Extraction Plants).
