As an integral part of the contract to pelletize sulfur and market it from Saudi Arabia, Devco was responsible for devising a program to reclaim, remelt, pelletize, and market more than 900,000 tonnes of sulfur which had been formed in large storage vats at Shedgum and Jubail. The sulfur at the base of the storage vats was contaminated, and Devco developed processes to purify the vat bottoms, removing dirt, sand, gravel and hydrocarbons, to thereby produce sulfur meeting commercial specifications. Devco offers these purification processes to eliminate environmental problems where storage areas must be cleaned up.
