AbstractGood dust control in a solvent plant includes control at the grain receiving pits, the storage area, the grain drier preparation building and the meal handling area. The techniques and equipment required are fairly stan‐dardized. The four types of collectors available are the cyclone, wet scrubber, filter and electrostatic precipita‐tor. Most State Air Pollution Codes are set up on the basis that a certain emission rate of dust into the atmosphere is allowed for a given amount of product being handled. In most cases collector efficiencies must be greater than 90% to meet the code. This makes the use of cyclones questionable.
