Abstract
The invention is a system and method for recovering volatile organic gases emitted by solid pellets of a polyetheylene resin product. In the process for making the resin product, the pellets are sampled for product quality and blended to obtain a more uniform mixture, before being transferred to shipping or storage containers. During this process gas must be purged from the sampler and blender vessels to prevent it from building up to an explosive level. In the purging step, outside air is blown through the blender and sampler vessels to mix with the organic gases therein, and this mixture is passed to a furnace, to provide combustion air for the furnace.
