摘要

ExxonMobil has commissioned new facilities at its Baytown refinery that it claims will reduce the sulphur content of the motor gasoline it produces by 90%.The three-year project included construction of what is reported to be the world's largest SCANfining unit,which uses ExxonMobil's proprietar SCANfining process to selectively remove sulphur from cracked naphtha while minimising the loss of octane in the resulting gasoline.
