Is cashew nut shell liquid a flow improver for heavy crude?
In the present study, a bio-based additive, i.e., Cashew Nut Shell Liquid (CNSL) has been tested as a flow improver for heavy crude. CNSL was obtained from waste cashew nut shell by means of mechanical extraction, and it was completely characterized. Similarly, the crude oil used in the study was characterized for its physio-chemical properties.
How to extract cashew nut shell liquid?
1. When extracting cashew nut shell liquid from cashew nuts, three basic techniques are typically used. The roasting method, the hot oil bath method, and using a solar cooker are the three options. In addition to removing the corrosive CNSL, roasting also renders the shell brittle, which speeds up the breaking process.
How is CNSL obtained from waste cashew nut shell?
CNSL was obtained from waste cashew nut shell by means of mechanical extraction, and it was completely characterized. Similarly, the crude oil used in the study was characterized for its physio-chemical properties. Also, the crude oil was subjected to Saturates, Aromatics, Resins and Asphaltene analysis and Fourier Transform Infra-Red analysis.
What is cashew nut shell liquid (CNSL)?
Cashew nut shell liquid (CNSL), a byproduct of the cashew industry, stands out as a unique renewable starting material amongst others due to its peculiar structural feature, low cost, and availability.
