THE SITUATION

A plastic recycler in their recycle process milled together carpet tile trimming composed predominately of nylon and PVC, with sufficient intensity to create a process temperature of 350-400 degrees F, while generating a densified, homogeneous plastic compound, which is the targeted recycled material. The process causes plastisols within the PVC to vaporize; creating a mist and an opaque exhaust stream. The visible emissions did not meet the stringent opacity requirements.

THE SOLUTION

The company tried several technologies with little or no success.
The manufacture contacted CECO Filters to discuss their concerns. After they consulted with CECO engineers they decided to rent a CECO Mist Collector trial unit to run tests on its effectiveness in removing the visible emissions. The trial unit was designed for the highest efficiency possible using Brownian diffusion fiber bed technology that results in less than 5% opacity.

THE RESULT

After six weeks of satisfactory results meeting the opacity controls limits the company purchased a complete CECO CMC Mist Collector system. Following a successful installation and documented performance results CECO Filters received an additional order for another collector for their secondary plant.
