ABSTRACT:
A refiner steam separation system according to the present invention includes a blowline for transporting a mixture of fiber material from a refiner to an inlet of a steam separator. Waste steam is discharged from the separator through a waste steam outlet. Cleaned fiber material is discharged from the separator through an exit, which prevents a substantial portion of the waste steam from passing through the exit. A relay pipe communicates with the exit and a dryer duct, and transports cleaned fiber material therebetween. A resin input communicates with the relay pipe, and supplies resin therein. The resin is mixed with the cleaned fiber material prior to the cleaned fiber material being dried in the dryer duct. The present invention is also directed to a method of reducing VOC emissions generated during refining cellulosic fibrous material.
