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. The technique can significantly reduce the clean-in-place (CIP) cycle time and reduce the need for CIP chemicals. At the same time, it can recover product and reduce wastage.
Integrated in the production process to maximise efficiency, the Ice Pigging™ machine can significantly reduce the time and water used in flushing a pipework system. 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™ machinery can be integrated into the manufacturing facility to automatically create tailored ice slurry to meet production requirements and it can be located to clean and recover product from multiple production lines.
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.
Ice Pigging™ is highly effective at removing materials and substances in pipes that require a particularly high quality clean. In processes where there is a need to recover high value product, Ice Pigging™ delivers a fast and effective solution. 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.
