Abstract
A clean-in-place system for piping systems uses a pig train having a dry ice and glycol section. The pig train is moved through the piping system as part of a cleaning sequence. The system and method of the disclosure provide an alternative, effective clean-in-place system that significantly reduces water, chemical and energy usage as well as significantly reducing the related environmental impact.
