Description
This paper reviews the different types of gas cleaning equipment in terms of energy consumption and focuses upon new equipment designs which are capable of giving greater collection efficiency at lower energy uses. Newer designs which will be evaluated are wet scrubbers using electrostatic augmentation, crossflow packed scrubbers using flux forces and condensation, and scrubbers using waste thermal energy.
These are energy efficient scrubbers that in many applications can operate at hydraulic power of less than 3 hp per 1000 ACFM (1.3 w per 1.0 m³/hr) and give good removal efficiencies on particles having an aerodynamic cut diameter of 2 microns and smaller and extending into the submicron range. An example showing a comparison of first costs and annual costs of operating scrubbing systems required to give cleaned air meeting environmental protection requirements and hygienic threshold limits will also be included.
