According to Lee Fagg, a consultant with Nexant Chemsystems, during the period 2012-2020, the world needs to add about 40 million tons of ethylene per year to meet demand growth.
Fagg said: "By the continued growth of emerging markets, the global economy is expected to recover from the current recession, so it needs a lot of new ethylene capacity."
Fagg said that while the demand is increasing, another important feature facing the global olefin industry is the significant change in the types of raw materials. In the past decade, the process of lightening the feedstock for ethylene production has been accelerating. Lightweight feedstocks include ethane and other natural gas liquids (NGLs), which are mainly affected by the investment in the Middle East to build a large number of ethane-based cracking devices.
