Investing in a crude oil distillation unit (CDU) is a major decision for any refinery or oil-processing business. A CDU is often considered the starting point of the refining process because it separates crude oil into different fractions according to their boiling ranges. However, choosing the right unit involves much more than comparing processing capacity and equipment prices. Before making an investment, companies need to evaluate feedstock characteristics, production requirements, energy consumption, equipment reliability, safety, and long-term operating costs. https://www.purepathtech.com/petroleum-refineries/crude-oil-distillation-unit
