Fouling Testing for Crude Oil and Petroleum Products

Large Crude Jar

HTRI experts use our proprietary fouling rigs to research and assess fouling of petroleum and petroleum products. We provide data that can help keep heat exchangers running longer, cleaner, and more efficiently. Our crude oil fouling testing program has developed reliable and repeatable techniques that assess the in-tube fouling potential for crude oil and petroleum products. Results are provided in a detailed, customized report. More information can be found on the Fouling Testing page.

Our knowledge is your power.


Evaluating Fouling Development on Heat Exchangers

HTRI Edgeview®, an inventive solution for fast, accurate evaluation of heat exchanger performance, was developed to identify operating regimes that exhibit reduced fouling tendencies in shell-and-tube heat exchangers. Edgeview has been used effectively to evaluate measured fouling development in operating facilities. The solution leverages more than 55 years of HTRI research expertise. HTRI Consulting Services utilize Edgeview to deliver an effective, customized solution that incorporates the unique requirements of each client.

Preventing Fouling

Vapor infusion is an environmentally friendly alternative that reduces fouling and protects heat exchangers and process equipment that use water as a process stream. It safely generates scrubbing, transitory bubbles to reduce the formation of foulants on heat exchanger surfaces while imparting targeted and reduced chemical treatments. HTRI is the exclusive worldwide provider for vapor infusion technology for heat exchanger and water processing applications using fluid flow (including liquid or gas).
