Petroleum is a complex mixture of hydrocarbons and paraffins in some areas, and aromatics and cyclo-paraffins in other areas. It is the primary source of automotive fuels and lubricant oils. Thought to have been formed from decomposition of animal and vegetable life under heat and pressure during geologic periods, Petroleum occurs usually in deep rock strata but sometimes near to the surface. When cracked and refined, it produces hundreds of petrochemicals that are converted into tens of thousands of products.

Crude petroleum (called also Crude Oil or Mineral Oil) contains about 80 percent carbon compounds, 11 percent hydrogen, and 1 to 2 percent of nitrogen, oxygen, and sulfur. In most oil fields, oil and natural gas occur together, gas being the top layer on crude oil under which may lie water. One barrel of petroleum equals 5604 cubic-feet of natural gas, 1.45 barrels of liquefied natural gas (LNG), or about one barrel of gas oil.

Tarsco Bolted Tank's factory-baked epoxy coatings provide the best corrosion protection in storage tanks. Our liquid immersion coating has been tested and is unaffected in extended immersion in boiling de-ionized water. Tarsco bolted tanks are low maintenance and durable enough for a wide range of petroleum products, including diesel fuel and fuel oil and are ideal for a variety of liquid products, preventing costly leaks and providing environmentally safe storage.
