Gas flare from a venting pipe at an oil refinery. This is the disposal,by burning,of small amounts of natural gas that are within the crude oil. This method is used where the volume of gas is not sufficient to justify extraction for commercial use. In an oil refinery,crude oil is heated and passed through catalytic cracking towers to obtain the components (fractions) that range from heavy oils to gases. Photographed in Alberta,Canada | |
