Understanding Automotive oil

Image
  Automotive oil is a base oil that is enhanced with various additives particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers. Automotive oil is ideally used for the lubrication of internal combustion engines.  Automotive oil levels need to be checked on a regular basis. Even if you have a new car, and you take it for servicing, you still need to check your car’s oil level. Usually, the older your car engine, the more oil it will tend to use (or leak) and the more often you need to check the dipstick to make sure it stays above the minimum level. It is crucial that one maintains the car’s minimum oil level, otherwise key engine components will be starved of oil and either wear prematurely or fail catastrophically. Which could result in a lot of expense and trouble—far more than the cost of a quick oil change at the gas station.  However, keeping your oil topped up is not the only thing to check, constant mechanical and chemical st

Industrial Gases in Petrochemical Processing

  Chemicals derived from petroleum or natural gas are known as petrochemicals which are typically extracted during the refining process as crude oil and natural gas liquids are cracked or distilled.  Chemical plants convert oil, natural gas, air, water, metals, and minerals into chemical products. They produce many important building blocks for industry processes, including ethylene, propylene, butadiene, and aromatics. Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions. Olefins and aromatics are the basic components for a wide range of materials such as solvents, detergents, and adhesives. Olefins are the basis for polymers and oligomers used in plastics, resins, fibers, elastomers, lubricants, and gels.  In any refinery, the reliability of rotating equipment is crucial to efficient, cost-effective production. This includes, for example, gas and air compressors, ball valves, centrifugal pumps, mechanical seals, gearboxes and screw connectio
