CONVERSION OF A LIGHT SWEET REFINERY TO A HEAVY SOUR REFINERY

This is a unique way of upgrading an existing refinery to processheavy sour crude. The system does not significantly modify an existingsweet refinery. Rather, a hydrocracker is used at the existing light sweetrefinery location to create light sweet crudes from heavy sour crudes prior toprocessing in an existing sweet refinery.
