At its petrochemicals complex in Feluy, Belgium, Total today inaugurated a demonstration plant intended to produce olefins and polyolefins from methanol. The integrated unit is the world’s first application of an innovative technology that helps to diversify the source of plastic feedstock.The inauguration was attended by Jean-Claude Marcourt, Minister for Economy, Employment and Foreign Trade for the Belgian region of Wallonia, François Cornélis, Vice Chairman of the Executive Committee and President of Chemicals at Total, and Jean-François Minster, Senior Vice President, Scientific Development, Total.
From coal, natural gas or biomass to methanol to propylene to polyolefins
Worldwide, the petrochemicals industry currently relies on oil and natural gas derivatives, naphtha or ethane, to produce olefins. These are subsequently converted into polyolefins, the raw material for plastics. The pilot plant at Feluy was designed to assess, on a quasi-industrial scale, the technical feasibility and cost effectiveness of two integrated processes that produce olefins and subsequently polyolefins from methanol, which can be obtained from natural gas, coal or biomass. First, the UOP/Hydro Methanol To Olefins (MTO) process converts methanol into light olefins (ethylene and propylene) and heavier olefins. The heavy olefins are in turn converted into light olefins, more specifically into propylene, via the UOP/Total Petrochemicals Olefin Cracking Process (OCP). All of these olefins are then converted into polyolefins at the existing pilot polymerization unit located nearby, at Total’s research center in Feluy.
€45 million investment for diversification and increased propylene yield
Requiring a €45 million investment, the new MTO/OCP unit is a major technological and strategic project that will help Total to meet two key challenges. First, it will enable the Group to diversify its sources of petrochemicals feedstock, by reducing its dependence on oil. Second, the integrated unit will increase propylene yield, which is a major market advantage at a time of strong international demand for polypropylene.
“Given that energy demand will continue to grow, petroleum supply will be tight and the prices should stay at a high level, we firmly believe that the methanol to olefins process will play a vital role in the production of petrochemical products in the future,” said François Cornélis. “Integrating the methanol to olefins and olefin cracking processes makes it possible to produce light olefins at a very reasonable cost.”
