Waste management system in petroleum refinery

The purpose of oil refineries is to produce marketable products from crude oil or other hydrocarbon feedstocks.The refining processes have environmental impact on their neighbors and on the air, water and land, and it is important that refiners at least meet the standards set and implement continuous improvements to minimize their impact if they are to retain community acceptance.The best way to reduce pollution is to prevent it in the first place. Some companies have creatively implemented pollution prevention techniques that improve efficiency and increase profits while at the same time minimizing environmental impacts. This can be done in many ways such as reducing material inputs, re-engineering processes to reuse by-products, improving management practices, and employing substitution of toxic chemicals.This paper looks at the types of pollution created by petroleum refineries, the environmental impacts of that pollution and the technologies and techniques available to enable refineries to meet environmental standards through pollution prevention.
