CASHEW NUT SHELL LIQUID (CNSL)
Cashew Nut Shell Liquid
Cashew Nut Shell Liquid (CNSL) is a natural oil extracted from cashew shells. Its main component is anacardic acid, which has a molecular structure consisting of a phenol ring, a hydroxyl group (-OH), and a carboxyl group (-COOH).
Under the effect of heat, the oil undergoes chemical transformations that form unsaturated carbon-hydrogen bonds and trigger polymerization, enhancing its thermal properties and expanding its industrial applications.
Key Characteristics of Cashew Nut Shell Liquid
- High heat retention, suitable for industrial combustion systems
- Stable combustion performance, comparable to FO oil
- Flexible blending capability with FO oil
- Natural and abundant raw material source in Vietnam
- Helps businesses optimize fuel costs
Industrial Applications of CNSL
CNSL is currently widely used as a fuel source in many industries, including:
- Silicate manufacturing plants
- Ceramic tile industry
- Metallurgical industry (aluminum)
- Industrial boilers
Thanks to modern production technology, cashew nut shell liquid is increasingly refined to meet high quality standards and ensure stable performance in industrial systems.
A Substitute and Blending Solution for FO Oil
In practice, CNSL is commonly used as a blending solution with FO oil to optimize both performance and cost.
Benefits of using CNSL
- Improves heat retention compared to using 100% FO oil
- Reduces overall fuel costs
- Allows flexible adjustment of blending ratios based on operational needs
The blending ratio tends to increase over time due to the economic and technical advantages that CNSL offers.
