A worker checks the temperature of molten paraffin scale in a large vat.

Definition

Noun: 1. A partly refined paraffin wax: "Paraffin scale" refers to a specific intermediate product in the petroleum refining process. It is a crude or semi-refined form of paraffin wax, which is a white, odorless, solid mixture of hydrocarbons. This substance is obtained during the chilling and pressing of petroleum distillates and requires further purification to become fully refined paraffin wax.

Usage Examples

• The refinery produces paraffin scale as an intermediate before final purification.
• This batch of paraffin scale has a higher oil content than the previous one.
• The chemical plant purchases paraffin scale to process into finished candles and coatings.

Advanced Usage

• In industrial contexts, the quality of paraffin scale is often measured by its oil content and melting point, which determine the level of further refining required.
• The term is primarily technical and is used within the petroleum, chemical manufacturing, and wax production industries.

Variants and Related Words

• Paraffin wax (n): The fully refined, finished product used for candles, lubrication, and sealing.
• Slack wax (n): A related, often less refined, intermediate product with a higher oil content than paraffin scale.
• Microcrystalline wax (n): A type of wax derived from petroleum but with different crystalline structures and properties than paraffin wax.

Synonyms

• Crude paraffin wax
• Semi-refined paraffin
• Scale wax

Related Terms (Industry-Specific)

• Dewaxing: The refining process that removes wax (like paraffin scale) from lubricating oils.
• Sweating: A traditional purification process where paraffin scale is slowly heated to separate different melting-point fractions.
