If there is a high amount, it will have a naphthalike smell, otherwise it will smell more of tar. In the process of coaltar distillation, the distillate is collected into four fractions; the "light oil", which remains lighter than water, the "middle oil" which passes over when the light oil is removed; the "heavy oil", which sinks; and the ...

Coal tar distillate (of which creosote is a product) is a dark brown liquid that is produced by thermal distillation of coal tar. Coal tar is a biproduct of producing coke for steel production from coal via a pyrolytic process in "coke ovens" where the coal is heated to over 1,000°C in an oxygenlimited condition (Ametek 2022).The tar is distilled into lower, medium, and highboiling ...
