Fugitive Emissions For Benzene
An oil refinery releases toxic gases in the earth’s atmosphere. When this refinery is not under an authorized control, the air pollution emissions that it causes are referred to as ‘fugitive’ emissions. There are stacks of pipe laying around that help move the partially finished product. These pipes allow gases to escape into the atmosphere through vents in them. |

We are all aware that benzene is a potentially dangerous compound. Although it has been in use for sometime now, experiments are being conducted to reduce its toxicity. The compound poses s serious threat to human life. Benzene released in the atmosphere can lead to poisoning of the central system. It has been declared a carcinogen. Even if benzene side effects can be controlled in the products that contain it, release of benzene emissions is still a serious concern. Proposals have been put forward to reduce the release of fugitive emissions of benzene from benzene storage tanks.
One way of taking care of these emissions is by adding triethylene glycol dehydrators to benzene. Glycol absorbs high volume of benzene because the latter being an aromatic compound easily dissolves in triethylene. To ensure maximum success, the pressure should be high and the temperature should be maintained at low. When this combination is put in a regenerator, glycol is completely isolated from benzene. This removal process occurs at high temperature but low pressure. Once it is done, benzene is removed from the regenerator. What is left behind are the recently emitted vapors.
If benzene emissions are to be secluded from glycol, then care should be taken in the first phase of mixing glycol with benzene. During this step, glycol should be circulated at a controlled rate. Water content of glycol should be lowered. This will reduce the rate of circulation of glycol. Hence benzene emissions will automatically drop down. This process ensures 100% success rate in reducing the level of fugitive emissions from benzene.
