Due to the massive demand for propylene in China, Asia has faced a significant shortage of this critical petrochemical feedstock in recent years. This growing demand, coupled with rising prices, has attracted substantial investment into the region's propylene sector. According to CMAI analysis, Asia is set to become the world’s largest new source of propylene over the next five years, with approximately 41% of new capacity relying on alternative technologies. This shift will elevate the share of propylene from these technologies in Asia from less than 7% of global production in 2005 to 12% by 2010.
The analysis also highlights that propylene demand growth continues to outpace that of ethylene, while traditional steam cracking facilities have not kept up with the rising need. Most new steam crackers are based on ethane, which produces little to no propylene as a byproduct. As a result, propylene supply has tightened further, pushing prices higher. To meet future demand, heavy investments in alternative technologies are now essential.
Although specialized propylene production is generally more expensive than steam cracking or refinery-based methods, increasing propylene prices and improved efficiency in alternative processes have made them more attractive. Technologies such as propane dehydrogenation, metathesis conversion, high-carbon olefin cracking, fluid catalytic cracking (FCC), and methanol-to-olefins are gaining traction. These innovations are being actively developed and deployed across the globe.
In Asia, four transposition conversion units are currently operational, with a combined capacity of 580,000 tons per year. These include LG Chemical’s unit in South Korea, installations in Lishui and Wenshan, a facility in Kawasaki, Japan, and a 200,000-ton-per-year plant on Jurong Island in Singapore. Meanwhile, the Middle East and Africa are expected to invest heavily in flexible cracker units, refineries, and alternative technologies. By 2010, the region is projected to transition from a net importer to a net exporter of propylene. For example, Israel Carmel Olefin expanded its capacity to 210,000 tons/year, and Sasol plans to boost output by 340,000 tons/year through high-carbon olefin cracking in South Africa.
Most Middle Eastern investments focus on ethane-based crackers due to low-cost feedstock, but several propylene-related projects are also underway. The first wave of propylene investments will increase the region’s propylene share from under 5% to 10% by 2010, with new capacity coming from steam crackers, propane dehydrogenation, and other alternative methods.
In contrast, demand growth for propylene in North America has been modest, with limited new capacity additions. Over half of the 20 million tons/year supply comes from refineries, 45% from steam cracking, and only 2% from alternative technologies. The U.S. remains the world’s largest exporter of propylene and its derivatives, despite a declining market share. Europe, where steam cracking accounts for 72% of propylene production, is not investing in new crackers due to weak demand forecasts. Instead, the Middle East is expected to flood the European market with ethylene and derivatives, leading to a potential decline in European propylene demand and restricted supply growth from refineries and alternative sources.
