Pretratment BioTrac, Heat and Chemical Recovery

Pretreatment is one of the most critical and challenging process step. The BioTrac is a continuously operated system, designed for “steam explosion” of the biomass.

Chemical

Valmet has wide experience in flow control and automation solutions for the chemical industry. We cover the entire life cycle of processes, including new installations, rebuilds and services.

Chip washing

Producing quality MDF requires chips that are as free from impurities as possible. Debarking and screening are not enough. Chip washing is essential for producing board of low mineral content. The growing use of purchased chips, e.g. from sawmills, results in an ever-increasing need for chip washing. Existing impurities, in the form of metal, stones and sand, must be removed before the chips enter the process.

Mechanical Seals

To minimize the environmental impact Valmet has developed a new mechanical sealing system including double acting seals and closed loop water system which minimizes the water that enters the process. With this function you save fresh and waste water which results in reduced water costs and thermal energy savings due to less water to evaporate in the dryer.

Chip Bin

The chip bin acts as a buffer and it will also heat the chips with steam and secure good feeding of the raw material to the plug screw feeder. Valmet have developed a new type of chip bin to secure even and effective heating of the chips as well as provide good feeding to the plug screw feeder. Valmet chip bin's is also suitable to handle recovered steam coming from e.g the steam separator.
