Definition - What does Asphaltic Crude mean?
Asphaltic Crude is crude oil that contains 2% less wax in the residue obtained after distillation process. This crude oil is highly viscous in nature, sticky and in a semi-solid or liquid state. Asphaltic Crude is black in color and mostly found in natural deposits including crude oil extracted by petroleum organizations. Asphaltic Crude is separated from the crude oil through distillation process whereby it is removed from the higher-boiling hydrocarbons. Asphaltic Crude is also known as pitch, bitumen, petroleum asphalt or asphalt.
Petropedia explains Asphaltic Crude
Crude oil or Petroleum, which is a combination of naturally occurring hydrocarbons, is also composed of other compounds such as nitrogen, oxygen and sulfur to name a few. The composition of crude oil depends on the percentage of these elements. Thus, crude oil can be classified in three major categories – paraffin base, asphalt base and naphthene base. There is another base, i.e., mixed base. Asphaltic Crude is produced from crude oil by performing distillation process in different phases. The residue from vacuum distillation, which is heavy fuel oil, is sent over for a de-asphalting process which generates asphalt. Asphaltic Crude is then processed for further use in road construction and roofing shingles.
