Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit
When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... En savoir plus
