Chemical company Sasol Ltd. has given final approval to move forward with an $8.1 billion ethane cracker and derivatives complex at its existing Lake Charles manufacturing facility, the company announced Monday.

this world-scale petrochemicals complex will roughly triple our chemical production capacity in the United States, enabling Sasol to further strengthen its position in a growing global chemicals market," said Sasol president and CEO David Constable in a news release. "The U.S. Gulf Coast's robust infrastructure for transporting and storing abundant, low-cost ethane was a key driver in our decision to invest in America."
