ABSTRACT
Petroleum in the unrefined state is of limited value and of limited use. Refining is required to produce the products that are attractive to the market place.
Petroleum refining is a series of steps by which the crude oil is converted into salable products with the desired qualities and in the amounts dictated by the market (Priestley, 1973). In fact, a refinery is essentially a group of manufacturing plants that vary in number with the variety of products produced. Refinery processes must be selected and products manufactured to give a balanced operation. Crude oil must be converted into products according to the demand for each.
