Cured-in-Place Pipe (CIPP) Emission Capture System


Cured-in-place pipe (CIPP) is a popular sanitary sewer, storm water, and drinking water pipe repair technology. CIPP is one of the most widely used methods for pipeline repair, making up approximately 50 percent of all water pipe repair sites across the U.S. It is also used in Australia, United Kingdom, Germany, and other countries. Until recently, emissions from CIPP were believed to be just steam and vapor. Purdue University researchers discovered that CIPP emissions also contain organic solvent, partially cured resin particles, among other materials. Current emission monitoring uses gas meters to check for worksite chemical levels in the air; however, research has shown that multiple phases of materials exist. Gas meters can only identify gas phase contaminants and cannot capture emissions from multiple phases of materials. There is need for a system that captures emissions from CIPP. To determine worksite exposure risks, chemicals in the pipelines must be identified.

Technology Summary

Researchers at Purdue University have developed a system for capturing the multi-phase mixture emitted from CIPP technology. To capture a sample, the system is setup at the exhaust pipe for the CIPP process and at locations where fugitive emissions are released. This system allows for the real-time capture of emissions, sampling of the emissions, and monitoring of the air stream.
