Refined Bitumen is produced from selected crude oils through a process of Fractional Distillation. The crude oil is heated to temperatures of between 300 and 350 degrees Celsius and fed into a distillation column allowing the lightest fractions of the crude to separate, through vaporization, from the heavier fractions, which remain liquid. The production is a specialist activity and is not carried out in all oil refineries. Bitumen requires crude oils with specific characteristics and only some crude oils are suitable. There are 94 oil refineries in Europe (EU15) of which 63 produce bitumen.
Bitumen is an engineering material and is produced to meet a variety of end-use specifications based upon physical properties. Bitumen may be customised for special road applications and hundreds of grades have also been developed for the non-road industrial segment, including roofing and sound-proofing.
