DEHUMIDIFICATION IN BLAST CLEANING OPERATIONS

The paper describes dehumidification as a means of controlling the environment. It describes how dehumidification impedes the corrosion of steel and inhibits flash rusting, how to use dehumidification, and the impact of dehumidification on coating work costs. The dehumidifiction solution to the problem of corrosion is to reduce the moisture content of air to a safe level, typically 50% relative humidity or less at the steel temperature. A flow of air through the working area is required, and this air has to be dehumidified. In selecting the right type of dehumidifier for the job, emphasis should be put on the low temperature performance of the machine. Refrigeration dehumidifiers, and absorption or chemical dehumidifiers are discussed. It is noted that dehumidification is an easy to use, and not labor-intensive technique that is profitable in application.
