FLUID CATALYTIC CRACKING UNIT This unit is designed to process 50,000 barrels per day of gas-oil producing fuel gas, light hydrocarbons as raw materials for chemicals, high octane gasoline for motor fuel, household heating oil, and heavy fuel oil. Conversion of the gas-oil to the above mentioned products is promoted by a catalyst. This catalyst is a finely powdered natural clay and is circulated through the unit at a rate of 34 tons per minute. Conversion of the SINCLAIR REFINERY

SINCLAIR OILS 1' gas-oil to the final products is accompanied by a deposit of coke on the catalyst. This coke is burned from the catalyst to return its activity and also supply the heat necessary for the conversion. One unusual feature of the unit is the CO Boiler. This equipment converts the carbon monoxide in the flue gas from the unit to carbon dioxide and re- covers the heat released as steam for operating the unit. N
