Abstract: A demister includes demister filters that are rinsed in place with sprayed liquid during the normal operation of the demister. The filters remain in place and the demister continues to operate during the rinsing process. The disclosure also provides a method of rinsing the filters during the continued operation of the demister. The demister filters that can be moved between an operational position to an extended cleaning position where they can be cleaned without fully removing them from the demister. The filters are slid out through an open door to provide access for cleaning. The disclosure also provides a method of moving the filters out of the demister to extended positions and cleaning the filters in the extended positions.

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.

Abstract: An air material separator may be used to separate scrap from a conveying air flow while having a relatively low weight and short height so that the separator may be positioned within today's single-story manufacturing or processing facilities. The air material separator of the invention includes a generally cylindrical inlet chamber having a spiral wall that directs the inlet flow circumferentially and downwardly. An outlet chamber is positioned below the inlet chamber and includes a conical, perforated wall that allows the conveying air flow to escape through the perforated wall. The scrap carried by the conveying air flow cannot pass through the perforated wall and moves down and out an outlet at the bottom of the conical wall. The overall height of the device is substantially less than prior art air material separators.
