Cleaning In Place ( CIP)
Cooling water and process streams that are used for cooling or heating frequently caused fouling of heat transferring equipment. The fouling deposit causes decreasing of heat duty of this equipment. Therefore, for maintaining of the original heat duty, this equipment must be more or less frequently cleaned. Two different cleaning methods may be listed:
Mechanical cleaning (deposits are removed by brusher, abrasive balls, high pressure water, ultra- vibrations, etc).
Chemical cleaning (deposits are removed due to action of chemicals by means of dissolving).
Both methods may be applied either with or without dismantling of the heat exchangers. However, when dismantling of heat exchangers is difficult or impractical and/or when mechanical cleaning for some reason can not be used, then cleaning-in-place (CIP) version of the chemical cleaning may be the only practical way to clean this equipment.
