Mobile Zone Spray Booth Recirculation System
Abstract
Army painting operations emit a large quantity of Hazardous Air Pollutants in the form of Volatile Organic Compounds (VOCs). Increasing regulatory pressure is beginning to impact these operations, which is resulting in the consideration of installing air pollution control devices. Controlling the ventilation of once-through paint booths is extremely costly. The Mobile Zone Spray Booth Recirculation System recirculates the air in the paint booth and exhausts less than 90 percent of conventional once-through systems, which is less costly to treat. The system uses a mobile cab that moves with up to four degrees of freedom and provides the worker with fresh climatized air. Design studies for the Mobile Zone Spray Booth Recirculation System were conducted at four Army installations to demonstrate its applicability and cost effectiveness. The system was installed at Fort Hood, Texas with a recuperative catalytic oxidizer as the control device. Testing of the VOC control conducted in 2002 showed control efficiencies of 93 and 96 percent for two different paint applications. The system has undergone modifications and corrections since the testing. The system has met seven of the eight objective criteria related to performance and cost but has yet to meet the three subjective criteria related to usability and acceptance.
