Some of the major changes in the global ethylene market are expected to take place in the next few years until 2017. As per marketresearchreports, the global ethylene market will be primarily driven by diverging consumption growth and feedstock cost trends between different geographic regions. The US will continue to play a dominant role for both demand and supply of ethylene at a global level. The ethylene supply in the US has massively increased in the wake of the shale gas revolution. Many petrochemical companies in the US have triggered several billion dollar investment projects in the effort to expand the ethylene production and the most common feedstock for ethylene manufacturing, switching from naphtha and light gas oil to ethane. An overview of the ethylene industry also shows that abundant, low cost ethane supplies from the U.S. shale gas industry are some of the important factors supporting the revival of large investment projects in this region.
