Injaz Projects Company Ltd., the Saudi Arabia-based developer that's part of a group buying chemical maker Petkim from Turkey's government for $2.04 billion, said it expects to close the deal next month. Injaz is “optimistic” the acquisition will close at the end of January, Chief Executive Officer Ameen Killidar said in an e-mailed statement yesterday. “Turkey's petrochemical sector could be worth as much as $12 billion annually by 2015, so we are keen to get into the market now.” Turkey's asset-sales agency on Nov. 22 said it approved Petkim's sale to Injaz with partners Turcas Petroleum and State Oil Co. of the Azerbaijan Republic. Turkey in October chose the Injaz-led group to get a 51 percent Petkim stake, even though rival Russian-Kazakh group TransCentralAsia made a higher bid. Turcas and Socar in July won approval to build a $4 billion oil refinery at Turkey's Ceyhan port to process crude arriving from Azerbaijan. Turcas holds a 25 percent stake in the bidding group and Socar 26 percent. The remaining 49 percent is owned by Injaz, Turcas has said. Riyadh-based Injaz was founded in 2006, according to its Web site. Its backers include the al-Muhaidib Group, the al-Fozan Group and private equity company Amwal al-Khaleej
