Safe Removal of Ethyl Mercaptan generated during rubber de-vulcanizing process at DSI (D Samson Industries) plant in Bogahagoda
FEPL was invited to extract residual Ethyl Mercaptan discharged after de vulcanizing process at DSI plant in Boghagoda, Galle in Sri Lanka.
This particular plant processes used rubber to reclaim its original state thereafter to convert it to more durable form.

Several Autoclaves are used in the process and a gas called Ethyl Mercaptan is released during de-vulcanizing operation which is later incinerated to avoid any de-gradation of environment. However, a small percentage trapped in the de-vulcanized rubber is released into the environment when the product is taken out of autoclave for further processing. This was quite a challenge and a solution was needed urgently by DSI. FEPL undertook the challenge and designed a system which collects all the residual Ethyl Mercaptan before it being discharged into the environment at a very high elevation.
The area where de-vulcanized rubber is stored was fully enclosed. The service point of an extraction blower was designed to keep inside concentration of Ethyl Mercaptan below threshold limit.
The extraction blower is being connected to 150 feet high stack to shoot up Ethyl Mercaptan into the sky
Connecting the final piece of duct to 150 feet high stack
The project was a grand success and issues plant had to face in operation were completely resolved.
