A 400,000-tonne-per-year polypropylene (PP) unit at PetroChina’s Guangxi Petrochemical, part of a refining and petrochemical integration and upgrading project, successfully completed a trial run with actual feedstock on September 19, producing its first batch of qualified pellets, according to local industry outlets.
The project is a refining and petrochemical integration and upgrading initiative undertaken by Guangxi Petrochemical, located in Qinzhou, Guangxi, building extensive downstream petrochemical facilities on top of its existing 10-million-tonne-per-year refining capacity. The unit that completed its trial run is a 400,000-tonne-per-year PP extrusion and granulation line, which produced its first qualified pellets on September 19 after a sequence of steps including starting the main motor, feeding raw material, die cooling, mold closing, and operating the pelletizer. The specific process technology licensor has not been identified.
The total investment for the entire project is reported at approximately 30.5 billion yuan. The refining and petrochemical integration and upgrading initiative includes a newly built 1.2-million-tonne-per-year ethylene cracking unit and a package of 14 downstream chemical process units, which are expected to increase output of basic petrochemical feedstocks such as ethylene, propylene, and butadiene by approximately 2.76 million tonnes. The PP unit that completed its trial run has a capacity of 400,000 tonnes per year.
This successful trial run is a representative case of the “oil-to-chemicals” transition strategy being pursued by China’s refining industry, reflecting a common trend among state-owned refiners to increase the share of high-value-added petrochemical products in response to shrinking refining margins.
China has simultaneously pursued numerous large-scale ethylene and PP capacity expansion projects in recent years, and concerns over oversupply of commodity petrochemical products including polypropylene have been consistently raised within and outside the industry. The startup of this Guangxi Petrochemical unit is an extension of this wave of capacity additions and could exert additional downward pressure on domestic and international PP prices. At the same time, the integrated model in which a refiner vertically integrates its own refining facilities with downstream petrochemical units can serve as a competitive advantage in terms of reducing feedstock procurement costs and diversifying oil price volatility risk, which may prompt refiners and petrochemical producers elsewhere to benchmark similar integration and transition projects. This is a matter worth watching for its potential impact on the export competitiveness of Korean and Southeast Asian producers amid the restructuring of Asia’s regional PP supply chain.
Attention will focus on when the PP unit that completed its trial run transitions stably into full commercial operation, and whether the startup schedule for the remaining 14 downstream unit packages, including the 1.2-million-tonne-per-year ethylene cracker under construction, will be disclosed in sequence. In addition, the impact of this capacity expansion on PP prices in China and the broader Asian region, and whether PetroChina will announce further similar integration and transition projects at its other affiliated refineries, are also points to watch.
