Shandong Shouguang Luqing Petrochemical Co. Ltd. (SSLPC) formally has accepted performance of Honeywell International Inc. subsidiary Honeywell UOP LLC’s C4 Oleflex process unit for production of isobutylene at its integrated refining and petrochemical complex in Bohai Industrial Park in Shouguang City, Shandong Province, China (OGJ Online, Sept. 15, 2014).
First commissioned in November 2015, the 170,000-tonne/year unit has enabled SSLPC to begin producing isobutylene—a key ingredient for making high-octane fuel and synthetic rubber—nearly a year ahead of schedule to help support growing demand for fuel and petrochemicals in China’s industrial sector, Honeywell UOP said.
Following its gradual build to full capacity, the unit continues to operate as planned at normal rates of production.
Initially scheduled for startup in 2016, the C4 Oleflex unit—China’s first—began operating only 20 months after project kick-off as a result of preengineered unit components, the service provider said.
Alongside engineering design, catalysts, adsorbents, specialty equipment, staff training, and technical service for the unit, Honeywell UOP also provided technology licensing for its proprietary C4 Oleflex process, which uses catalytic dehydrogenation to convert isobutane to isobutylene.
In addition to the 170,000-tpy C4 Oleflex unit, SSLPC’s integrated refining and petrochemical complex includes the following capacities:
• Crude distillation, 3 million tpy.
• Catalytic cracking, 2.1 million tpy.
• Catalytic reforming, 1 million tpy.
• Delayed coking, 1.5 million tpy.
• Diesel hydrotreating, 1.2 million tpy.
• Gasoline hydrotreating, 1.2 million tpy.
• Alkylation, 200,000 tpy.
• Asphalt, 600,000 tpy.
• Sulfur recovery, 30,000 tpy.
• Aromatics, 800,000 tpy.
• Gas separation, 600,000 tpy.
• MTBE, 100,000 tpy.
• Polypropylene, 200,000 tpy.
