The Impact of Air pollutants on oil industry and its relation to safety and occupational health inside the working environment (Case study in elhadisa extraction mill)

 Vegetable Oils are types of cooking oil which are suitable for human consumption including sunflower, canola, soybean, cottonseed, groundnut, linseed, sesame, and moringa oils. Vegetable oil which can be extracted from oilseed is considered one of the main components of our food. Soybeans are one of the main sources of oil crops around the world. Soybean oil and protein are major products for food, livestock feeds, and industrial applications. Soybean oil, extracted from the seeds of soybean, is one of the most widely consumed cooking oil across the world. Soybean oils are usually preferred over other vegetable oil for various health benefits including better heart health, improved immune system, improved growth, and reduced cognitive diseases. It is a resource of edible oil and has other food and industrial applications. The process for soybeans typically consists of five steps: oilseed handling/elevator operations, preparation of soybeans for solvent extraction, solvent extraction and oil desolventizing, flake desolventizing, and oil refining. In each step of manufacture, there are emissions that have effects on the environment, employees and the economics of the business. 
     In the industry, expelling and hexane extraction are the two typical processes for soybean oil production. But Hexane extraction is the most common method used in the industry to produce soybean oil due to its high oil recovery and lower producing cost, however, it has characteristics that make it challenging to use, including high flammability. With the demands of soybean oil increasing, either in food or industrial applications, expansion plans are being considered by many companies to increase production capacity.
     Therefore, this study included a study of one of the vegetable oil extraction plants Elhadisa located at Sadat Industrial City.  Where this study focusesd on monitoring and evaluation of air pollutants (emissions) resulting from each stage of manufacturing and discussed their impact on health, environment and  economy, Also  the study discussed & represented the solutions to reduce air pollutants, emissions and the output particles, which in order  provide protection for an environment, employees and economic.
