Refiners try to make every last drop of crude oil into products, but that's technically infeasible.
Some of the crude oil is turned into fuels that are burned to run the refining process, and burning fuel puts chemicals into the air. Also, some vapors leak from pipes, tanks, and other equipment, and cause chemical releases into the air. Chemicals that result from burning fuel or leaking equipment are called emissions.
