oil and gas upstream vs downstream

Liquid paraffin has been used extensively as a lamp gasoline for over a century. Coal oil, lamp oil and liquid paraffin are actually interchangeable terms. In some parts of the world, equivalent to Great Britain, liquid paraffin is the frequent identify given to lamp fuel, however within the U.S., liquid paraffin is solely known as kerosene.

Earlier than the invention of oil in Titusville, Pennsylvania, lamp oil, identified then as “coal oil,” was produced from an oil-bearing form of coal referred to as cannel coal. However, coal-based mostly manufacturing was more time consuming and thus dearer than producing kerosene from liquid crude. Prior to those developments, most Americans burned whale oil of their lamps.

Kerosene, like other petroleum byproducts, is refined from crude mineral oil by way of the technique of fractional distillation. Crude oil is boiled, and as the vapors of the constituent elements rise, they are captured and condensed. Crude oil is definitely a posh hydrocarbon “soup,” which is composed of many lengthy-chain, carbon-based molecules, such as kerosene, gasoline, benzene and propane. Once giant portions of inexpensive kerosene have been being refined from crude oil, it spelled the demise of the nice New England whaling fleets.

Lamp Oil

During the infancy of the U.S. petroleum business, the kerosene produced was not of a consistently high quality. Because it typically contained impurities or water, when burned, the kerosene distilled throughout the late 1800s produced excessive quantities of black smoke. The liquid paraffin burned in at this time’s oil lamps is produced by refining kerosene a number of occasions. Each step on this process additional purifies the product and removes progressively more impurities, which is why many liquid paraffin lamp oils are marketed as being “smoke-free.”

Liquid Paraffin versus Paraffin Wax

Whereas they share a portion of the identical identify, liquid paraffin and paraffin wax are usually not the same factor. As previously talked about, crude oil incorporates a whole lot of individual compounds, paraffin wax being one in every of them. Because the wax vapors condense, they congeal into stable paraffin wax. Not like liquid paraffin, which is highly toxic if ingested, paraffin wax is chemically benign, which is why it has been used for many years to seal jars of homemade jams and jellies.

Liquid Paraffin Varieties

Along with the crystal-clear variety, liquid paraffin lamp oil has two different variants. Some sorts comprise dyes, such as pink, blue, green and even purple. In case your lamp chimney is manufactured from coloured glass, you may be in a position to purchase dyed liquid paraffin in the identical coloration. Different liquid paraffin lamp fuels contain a scent, equivalent to evergreen, clove or a floral scent, similar to roses. Other varieties are available which can be each dyed and scented.
