Common Mistakes. . .
CNSL Resin Manufacturing Process Owners make while making Vacuum Pump Selection !!!
- Wrong Sizing of the Vacuum Pump
- Mismatch in Pumping Speeds of the Booster and Backup vacuum pump leading to overheating of machines.
- No prefilter to backup pump leading to process particulate carryover and chocking of the backup pump
- No installation of intermediate condenser to trap and condense process vapours at a higher pressure.
- Choice of the right capacity of the Booster pump to deliver consistent and high pumping speeds to process for consistent deep vacuum
- Right instrumentation giving appropriate feedback at the right time.
- Common Integrated Electric Control Panel with PLC logic to control combination vacuum pumps simultaneously based on closed loop feedback.

THE TECHNOLOGY of Cashew Nut Shell Oil Distillation
Cashew Nut Shell Liquid (CNSL)Â or Cashew Oil or Cashew Nut Shell Oil is a dark reddish brown viscous liquid, extracted from a soft honeycomb structure inside the cashew shell. It is a natural and renewable biomaterial. Thus, it offers much advantage over synthetics. CNSL is often considered as cost effective and better modern materials for unsaturated phenols. Cardanol is basically a monohydroxy phenol with a long carbon chain in the meta-position. It has the potential as a substitute for phenol in resin phenolic-based chemical products. Main Process of Cardanol extraction from Natural CNSL comprises the conversion of natural CNSL into technical CNSL in which anacardic acid is de-carboxylated into cardanol.
Cardanol is distilled from Cashew Nut Shell Liquid.Cardanol can be manufactured in batch or continuous distillation process. A batch of Decarboxylated CNSL is heated to 250°C under high Vacuum in a reactor. After removal of initial impurities such as water and other low boilers Cardanol distillation begins and the vapour that is getting evaporated under vacuum is collected in a condenser and consensed with the right utilitis and collected in reciever.
Technical CNSL is obtained mainly from cardanol (60–65%), cardol (15–20%), polymeric material (10%), and traces of methyl cardol. Cardanol is sent to distillation for further purification.
Vacuum plays an important role in the evaporation process. Now days, water ring pump (WRP) is used in this process but these vacuum systems require lot of water as sealant fluid that circulate inside pump casing and in every minute process carry over contaminates the sealant water that’s why there is need of change of sealant water at regular interval of time. The treatment of waste water generated from WRP becomes difficult to treat and that makes the process less economical.
Everest Dry Screw vacuum pump has been used successfully in this process, No water contamination occurs as no sealing fluid is required that makes the process economical and keeps the environment clean.Automated scheduled flushing cycles are performed with suitable solvent at regular intervals to make the system maintenance free, hence adding value to the complete supply chain.

TESTIMONIALS
Everest Vacuum is a leading vacuum systems solution provider with great after sales service & support, they have done brilliantly well in understanding our
complete product & process requirement, designed a customised solution for us & supported us in commissioning of the product in the right fashion. We had to upgrade our installations from Stem/Water Jet ejectors to Dry Screw Vacuum Pumps looking into the enormous advantages that it would offer in terms of consistent deep vacuum & environmental friendly technology. We are very glad that we dealt with such a company who demonstrated high standards of professionalism along without losing sight of customer requirements. We would like to work with them again in the future & wish them all the best.
