Oil giant Shell has decided to begin the construction of a 325,000 barrels-per-day capacity expansion project at its joint venture Motiva's refinery in Port Arthur, Texas, US. According to Shell, the expansion will make it the largest refinery in the US and one of the largest in the world.

The expansion project will increase the refinery’s crude oil throughput capacity to 600,000 barrels-per-day. According to Shell, the expansion at Port Arthur is equivalent to building the first new refinery in the US in more than 30 years. The new production capacity will increase Motiva’s supply of Shell-branded fuels to the company’s wholesale and direct supply markets.

Shell is committed to meeting the global energy challenge by ensuring our global downstream business maintains a world-class manufacturing capability, said Rob Routs, executive director of downstream operations at Royal Dutch Shell. Shell’s investment in the Motiva Port Arthur Refinery expansion will lead to increased supplies of gasoline, diesel and aviation fuels in the US.
