FR Series ProGuard – Automated Back Wash Refinery Feed Filter System
Mesh backwashable filters are designed to remove solids from liquids by capturing solids on a semi-permanent filter element. At a predetermined pressure differential, the system reverses flow through each filter element in the system. The rotating arm cleans each filter element and removes the contaminants while filtering to provide continuous operation to provide cost effective continuous protection for the life of catalytic reactors.

The ProGuard automatic backflushing filter is specifically designed for the robust requirements of refinery streams for catalyst bed protection. It is important to remove particulate from the hydrotreater and hydrocracker feeds to protect the catalyst bed in the reactors and maintain the run life on catalyst beds at minimal cost.
For refineries to take advantage of opportunity crudes, the design of the filtration solutions needs to consider the higher variability in contaminants and the importance of optimized filtration systems cannot be overstated.
The ProGuard solution is designed to stand “Guard” and protect the catalyst beds. The solution can be tailored to the needs of the plant to suit the specific application.
