The petrochemical industry relies on hazardous computers and monitors to transfer petrochemicals from the extraction sight to chemical plants. They are also used in the chemical plants themselves, and for those uses see Rubber & Plastic industry.
When crude oil and natural gas is refined, petrochemicals such as ethylene, propylene, benzene are extracted and used to produce chemicals and plastics. Ethylene, propylene, and butadiene are typically used for making plastics, while benzene, toluene, and xylene are used to produce dyes and synthetic detergents. From this, thousands of products are produced, such as plastic, medicine, cosmetics, furniture, appliances, electronics, solar power panels, and wind turbines.
The refining process is where you will see industrial HMIs play a critical role because they are approved to operate safely and reliably in hazardous areas. The NEMA 4/4X rating indicates that the HMI is sealed in a way that protects internal components from exposure to dust, fiber, lint, dirt and hose directed water, as well as corrosion resistant.
Petrochemical applications also require industrial HMIs that work efficiently in wide operating temperatures, making them optimal solutions for outdoor applications.
With sunlight readable displays and glove friendly touch screens, industrial computers make data monitoring and collection quick and easy. Operators can easily view and access the industrial display, which allows them to be more productive with better oversight of the extraction machinery.
