ABSTRACT
The effectiveness of cleaning is dependent on ‘physical action’ or ‘force applied’ by a cleaning solution. Therefore, high turbulent systems are desired for efficient cleaning. For obtaining ‘physical action’ at fouled surfaces and smooth flow at normal surfaces, some “smart material” is required that acts like a fluid squeezing through complex geometries but behaves as ‘tough’ as it is a solid scraper which cleans the fouled surfaces. The ‘crushed ice in water’ or ‘ice pig’ is able to achieve many of the desirable characteristics of desired smart material. Ice pigging is an innovative method of removing fouling from topologically complex and demanding ducts. The process involves pumping ice slurry, a mixture of ice particles and liquids containing a freezing point depressant, through the fouled duct. The slurry acts in a similar manner as solid pig, displacing material downstream by applying shear. Hence, mechanical cleaning effect to the duct walls is achieved.
Key words: Freezing Point Depressant, Ice Pig, Ice Particle Size, Ice Slurry and CIP.
