Stages of Paraffin Production
The production of paraffin involves several processes, generally including the following stages:
-
Refining Crude Oil
The production of paraffin begins with the refining of crude oil. In this stage, crude oil undergoes distillation to separate its various components. Using different temperatures, hydrocarbons are divided into various fractions, some of which include heavy hydrocarbons used in paraffin production.
-
Dewaxing
After distillation, the dewaxing process takes place. In this stage, waxy hydrocarbons present in petroleum mixtures are separated from liquids. This is typically done through cooling and crystallization, allowing the waxes to solidify and be easily separated from the liquids.
-
Hydrogenation
To improve the quality of paraffin, a hydrogenation process may be employed. In this stage, hydrogen is added to the hydrocarbons to saturate any double bonds present in the carbon chains. This process increases the stability and reduces the reactivity of paraffin.
-
Refining and Purification
The final stage of paraffin production involves refining and purification, during which additional compounds and impurities are removed from paraffin. This is usually done using physical and chemical methods to produce high-quality paraffin with desired specifications.
What is Solid Paraffin?
Solid paraffin is a type of hydrocarbon that exists in a waxy, solid form. This material is typically derived from soft wax and is used across various industries due to its moldability and high thermal stability. Solid paraffin is mainly used in candle production, insulation coatings, and cosmetic products.
The characteristics of solid paraffin include a melting point ranging from 46 to 68 degrees Celsius and low reactivity with many chemicals. These properties make solid paraffin resistant to heat and moisture, recognized as a suitable option for various products.
Types of Solid Paraffin
Solid paraffin is divided into two main types: macrocrystalline and microcrystalline.
-
Macrocrystalline (Light Paraffin)
Macrocrystalline paraffins have larger crystalline structures and typically contain less oil. This type of paraffin is used in candle making and wax products and is considered an ideal option due to its stability and high burning quality.
-
Microcrystalline (Heavy Paraffin)
Microcrystalline paraffins have finer crystalline structures and contain more oil. This type of paraffin is used in cosmetic and personal care industries due to its adhesive and flexible properties, as well as for insulation in various products.
What is Liquid Paraffin?
Liquid paraffin, also known as liquid petroleum, is a clear and colorless hydrocarbon obtained from the refining of petroleum. This substance is primarily made up of saturated hydrocarbons and has a boiling point of approximately 265 degrees Celsius. Due to its non-toxic and safe nature, liquid paraffin is used in many industrial and pharmaceutical applications.
The characteristics of liquid paraffin include being non-polar and having high stability at various temperatures. These properties allow liquid paraffin to be used as a lubricant and moisturizer in the pharmaceutical industry and as an insulator to prevent moisture ingress in the food industry.
Applications of Liquid Paraffin
Liquid paraffin has many applications across various industries, particularly in pharmaceuticals and cosmetics. In the pharmaceutical industry, it is used as a lubricant and laxative to alleviate constipation. Additionally, it serves as a base for many cosmetic and personal care products, including creams and lotions.
In the food industry, liquid paraffin is used as a protective and insulating agent to prevent moisture ingress and maintain the quality of food products. It can be applied in food packaging to help preserve freshness and longevity.
Differences Between Solid and Liquid Paraffin
