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.

IPC Classes  ?

• B01D 46/00 - Filters or filtering processes specially modified for separating dispersed particles from gases or vapours
• B01D 46/69 - Regeneration of the filtering material or filter elements inside the filter by means acting on the cake side without movement with respect to the filter elements, e.g. fixed nozzles
• B01D 46/79 - Regeneration of the filtering material or filter elements inside the filter by liquid process

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.

IPC Classes  ?

• B08B 9/02 - Cleaning pipes or tubes or systems of pipes or tubes
• B08B 9/055 - Cleaning the internal surfacesRemoval of blockages using cleaning devices introduced into and moved along the pipes moved along the pipes by a fluid, e.g. by fluid pressure or by suction the cleaning devices conforming to, or being conformable to, substantially the cross-section of the pipes, e.g. pigs or moles
• B08B 9/057 - Cleaning the internal surfacesRemoval of blockages using cleaning devices introduced into and moved along the pipes moved along the pipes by a fluid, e.g. by fluid pressure or by suction the cleaning devices being entrained discrete elements, e.g. balls, grinding elements, brushes
