Advance Chemical Cleaning Methodology for Plate Heat Exchanger Scaling and Fouling Removal in Place

The heat exchanger like plate heat exchanger has extensive industrial application for exchange of heat energy applications because high thermal performance, minimum space requirement, and approachability to all areas with their lower capital and minimum operating costs as compared to others heat exchangers types. In plate heat exchanger scaling formed, when a mineral film coats the entire surface of a heat exchanger plate. The calcium-based salts are general form of scaling such as calcium sulfate or calcium carbonate and it's problematic because these calcium-based salts are reverse soluble salts. The salts are soluble in water at higher temperatures but the calcium based salt doing in opposite way and decreases the water solubility. Under some conditions, the plate heat exchanger also face the fouling issue which difficult to diffentiate with scaling during operational stage. Fouling and scaling is the deposition of unwanted material on a plate surface of a small channels of compact plate heat exchanger which badly affect the exchange of heat and reduction in flow. Fouling deposits narrowing the passages of plate surface gap area which increases the pressure drop. It's also reduces the effectiveness and increases the accompanying energy for operational and maintenance costs. In this paper different types of scaling and fouling formation mechanism are shown in different terminology. The advance chemical cleaning methodology develop to clean the different type of scaling and fouling without affecting the production losses, equipment damage with human and environment safety. The advance chemical cleaning in Place (CCIP) methodology for plate heat exchanger is based on acidic cleaning with different chemistry.
