Ice Pigging™ employs the special properties of a multiphase ice and liquid mixture. This allows the ice to flow like a liquid and move like a solid. An additive in the ice is used to control the composition of the ice slurry allowing it to flow like a liquid. The ice slurry is injected directly into the pipe system via a normal process connection point. It can then be moved through the pipe network under pressure.
The Ice Pigging™ technology is highly flexible, making it suitable for a diverse range of products and manufacturing industries including aerospace, automotive, chemical and pharmaceutical, electronics, paint and coatings.
As part of a preventative maintenance regime, Ice Pigging™ can provide a solution for pipes that suffer from restricted flow due to product build-up and other unwanted materials, such as biofilm. Ice Pigging™ can remove highly cohesive and high viscosity materials that conventional water flushing will not remove.
Ice Pigging™ is a rapid process, achieving excellent cleaning results compared with conventional water flushing.
“Ice Pigging™ has proved to be a ‘game changer’ for us. Ice Pigging™ has now been adopted for other production sites,” Johnson Matthey
The Issue: A manufacturing customer making high value compounds had concerns about the time being taken to achieve the high level of clean they needed in their production lines. They wanted to reduce the long flushing times associated with water.
The Solution: An AQL500 was installed at their factory site to service multiple production lines. An AQL200D was added to provide the Ice Pigging™ cleaning service to an occasionally used production line in a neighbouring building.
