Bulk liquid storage operator Bidvest Tank Terminals’ (BTT’s) R1-billion mounded liquefied petroleum gas (LPG) storage facility in Richards Bay, KwaZulu-Natal, is set to house the largest tanks in the world and is expected to greatly enhance LPG supply in Southern Africa once completed, the company has indicated. The facility will store LPG on behalf of independent LPG specialist Petredec, which ships the fuel from the US and Middle East. LPG is produced as a byproduct in the oil-refining process.
