Evaluation of Boiler and Heat Recovery Steam Generator Chemical Cleaning Waste Treatment Options: Lab-Scale Feasibility Testing of a Vapor Compression Thermal Evaporation Technique
Chemical cleaning of boilers and heat recovery steam generators is intended to remove deposits that can lead to corrosion and overheating. As a result of changes in environmental regulations, more plants need an alternative method for managing the waste from these cleanings. This report presents lab test results for a vapor recompression thermal evaporation process […]
