Heavy Slack Wax (2-5% Oil Content): Manufacturing, Uses, Applications, and Benefits

Heavy Slack Wax, with 2-5% oil content, is a crucial material in various industries due to its unique properties and versatility. This blog will delve into the detailed manufacturing process of heavy slack wax, its numerous uses, applications, and benefits. We will also highlight Peak Universal Business as a reliable supplier of this essential material.

Understanding Heavy Slack Wax (2-5% Oil Content)

What is Heavy Slack Wax?

Heavy slack wax is a byproduct of the petroleum refining process, specifically obtained during the production of lubricating oils. It is a semi-solid substance composed of a mixture of paraffin wax and oil. The “2-5% oil content” refers to the proportion of oil present in the slack wax, which significantly influences its properties and applications.

Chemical Composition

Heavy slack wax consists primarily of long-chain hydrocarbons. The exact composition can vary, but typically includes:

  • Paraffin Wax: Hydrocarbon chains (C20-C50) that provide structural stability and high melting points.
  • Oil: A smaller proportion of lighter hydrocarbons (C10-C20) that impart flexibility and lower the melting point.

Physical Properties

  • Color: Typically yellow to brown
  • Odor: Mild petroleum smell
  • Melting Point: 45-65°C (113-149°F), depending on the specific oil content
  • Density: Approximately 0.90 g/cm³
  • Viscosity: Medium to high, influenced by oil content
  • Solubility: Insoluble in water, soluble in organic solvents like benzene and toluene

Manufacturing of Heavy Slack Wax (2-5% Oil Content)

Production Methods

The production of heavy slack wax involves several key steps within the petroleum refining process. The primary methods include:

  1. Vacuum Distillation
  2. Solvent Dewaxing
  3. Filtration and Separation

1. Vacuum Distillation

The initial step in producing heavy slack wax is vacuum distillation, a process that separates crude oil into different fractions based on their boiling points.

  • Crude Oil Heating: Crude oil is heated to a high temperature in a distillation column. Under atmospheric pressure, this would cause thermal cracking, but vacuum distillation allows separation at lower temperatures.
  • Fractional Distillation: The heated crude oil is introduced into a vacuum distillation tower, where it separates into various fractions. The heavier fractions, including waxy distillates, are collected at the bottom.

2. Solvent Dewaxing

Solvent dewaxing is the key process for extracting wax from the heavy distillate fractions obtained from vacuum distillation.

  • Mixing with Solvents: The waxy distillates are mixed with solvents such as methyl ethyl ketone (MEK) or toluene, which dissolve the oil and separate it from the wax.
  • Cooling: The mixture is cooled to very low temperatures, causing the wax to crystallize and precipitate out of the solution.
  • Filtration: The solidified wax is separated from the solvent-oil mixture using filtration. The filtrate (oil and solvent) is collected separately.

3. Filtration and Separation

After the solvent dewaxing process, the wax is further processed to achieve the desired oil content and purity.

  • Filtering: The slack wax is filtered to remove any remaining solvent and oil impurities.
  • Centrifugation: In some cases, centrifugation is used to further purify the wax by spinning it at high speeds to separate out any remaining oil.
  • Final Refining: The wax undergoes final refining steps, such as bleaching and deodorizing, to improve its color and odor.

Uses and Applications of Heavy Slack Wax (2-5% Oil Content)

Heavy slack wax with 2-5% oil content is used across a wide range of industries due to its unique properties. Here are some of its most common uses and applications:

1. Candle Manufacturing
