Flare gas ratio

WebAn important variable in ejectors is the ratio of the motive fluid pressure to the discharge pressure. The larger the ratio, the smaller the amount of motive fluid required. Motive fluid pressure is typically around 5–10 times larger than the discharge pressure. WebAug 3, 2024 · At the same time, gas flaring contributes approximately 1% of man-made atmospheric carbon dioxide emissions globally. That is when flares combust hydrocarbons efficiently, converting them to carbon dioxide. In contrast, when flares burn poorly or go out, they pollute the air with more harmful gases.
