Lubricants produced using the cutting edge technology known as Hydrocracking.

Hydrocracking is a technology whereby the molecules of crude oil are actually chemically converted into highly desirable lubricant components of unparalleled quality - free of all impurities which contribute to the degradation of conventional lubricants in service. So pure in fact, that the advantage of hydrocracked base oils translate into synthetic-like performance characteristics in finished lubricants with regard to:

  • oxidation stability
  • low carbon-forming tendency
  • response to addititives
  • low volatility
  • viscosity stability
  • light color

What's more, hydrocracking, unlike traditional solvent refining, is not dependent on the availability of specific lube crudes and, thus, permits the economic production of lubricant base stocks from a wide range of crude oils. Hydrocracking can even convert high-sulpher, or sour, crude oils into base oils of higher quality than those produced by the traditional solvent extraction method-even if the traditional; process starts with a higher quality sweet crude.

  1. The multistage process begins by distilling feedstock from Conoco's Lake Charles Refinery in a giant vacuum tower. This unit boils the feedstock, separating it into distillates and vacuum gas oils.
  2. These waxy vacuum gas oils are gathered and piped to the hydrocracker, where the process of molecularly converting the oils begins.
  3. The hydrocracker's one foot thick walls are capable of withstanding pressure of 3,000 pounds per square inch and heat of 1,000 degrees Fahrenheit. In this high-temperature, high-pressure environment, the oil molecules become very reactive.
  4. By adding hydrogen to the molecules in this reactive state in the presence of a catalyst, the impurities which contribute to lubricant degradation-nitrogen, sulpher, oxygen and heavy metals- are eliminated. then with the addition of more hydrogen, again in the presence of a catalyst, molecular rearrangement of the feedstock occurs to produce the desired paraffinic-type lubricant base stock compounds, widely acknowledged for there superior quality as basic building blocks for finished lubricants.
  5. As the altered stock continues to the next processing stage, it is noticeably lighter in color, a result of the absence of contaminants.
  6. Now in the hydrodewaxer, undesirable wax is molecularly restructured to resist gelling and improve pumpability, even at exceptionally cold temperatures.
  7. finally, in the hydrofinisher, hydrogen is used once more to remove aromatics and the last traces of impurities and stabilize the molecular structure of the newly formed base stock, ensuring oxidation stability and extended lubricant service life. The rsulting finished stock is so pure it is water-white.
