According to the Chemical Market Association of Houston, USA, global ethylene demand grew by approximately 3.1% in 2005, a slight decline from the 4% to 5% growth seen in the previous two years. Similarly, propylene demand rose by about 4.1%, also showing a slowdown compared to the 5% growth recorded in the prior period. In 2005, total global consumption of ethylene reached 107 million tons, while propylene demand stood at 67.1 million tons.
Looking ahead, it is expected that ethylene demand will grow at an annual rate of 4.3% over the next five years, with propylene demand projected to rise by 4.8% during the same period. To meet this rising demand, ethylene production capacity is anticipated to increase by 5.4% year-on-year between 2005 and 2010, outpacing the 3.5% growth rate observed from 2000 to 2005. Propylene production capacity is also expected to expand by 5.1% annually during the 2005–2010 period, compared to 4.1% from 2000 to 2005.
By 2010, global ethylene supply is forecasted to reach 133 million tons. A significant portion of the new capacity will be located in the Middle East and Asia, accounting for 51% and 36% of the total, respectively. This shift highlights the growing importance of these regions in the global petrochemical industry.
