This study intends to shed light on associated gas from an economic standpoint, due to its various applications instead of oil, and from an environmental standpoint, due to the damage it does when burned during crude oil extraction. APG is a key raw material in the production of electricity and heating energy, as well as a variety of petrochemical products. Furthermore, APG has higher levels of water, which is known as wet gas, and hydrogen sulphide, which is known as sour gas. Helium, a marginally useful by-product, may be discovered in significant quantities. Different countries(Russia, Iraq, Iran, the US, Algeria, Venezuela, and Nigeria) have been the most prominent flare-ups over the past nine years. Also, these countries produced approximately 40% of the world’s oil per year, however they are also responsible for almost two-thirds (65%) of the world’s gas flaring. Flaring associated petroleum gas occurs for a variety of causes, which may be divided into difficult causes and soft causes. On another hand, When gas is flared, a considerable amount of pollutants are emitted. Flare stack smoke indicates an inefficient combustion process, which increases the volume of harmful pollutants generated into the surrounding environment, such as volatile organic compounds.
