Ice Pigging is a highly efficient line-cleaning and product-recovery technique. Ice slurry is pushed through production pipelines to clean and recover product.
It differs from conventional solid pigging in that the Ice Pig is capable of navigating complex pipework, which may incorporate changes in pipe diameter, bends, valve systems, heat exchangers and other obstructions with no risk of becoming stuck.
The Ice Pig is composed of fine ice crystals and a carrier fluid containing an additive used to maintain the correct fluid characteristics. In most cases the additive can be an ingredient already used in the product.
