Handbook on control technologies for hazardous air pollutants: HAP manual

The paper is based on an examination of engineering design and study type (+ or {minus} 30%) cost estimation procedures for 10 add-on control techniques for hazardous air pollutants (HAPs). The examination updated and revised the first edition of the EPA's HAP manual to reflect advances in point source control techniques and provide recent capital and annual cost data for each point source control technique. The HAP manual is designed to assist permit reviewers by providing basic engineering and cost equations for common gaseous and particulate control techniques. These equations enable the user to obtain approximate design values and capital and annual costs of the proposed equipment, which can then be compared to the permit applicant's values.
