What We Do at NMIS
Our Process: Burners, incinerators, combustors, and dryers typically require downstream process vessels that quench, cool, scrub or absorb the gases. These process vessels are moderate to severe service and require lining systems that incorporate membranes to protect the steel or FRP Shell and various acid brick, carbon, graphite or specialty ceramics to protect the membrane.
- Visual observations and physical testing provide plant reliability or plant inspectors additional perspective on the operational life cycle of brick-lined process equipment.
- Observation Reliability Reports with repair recommendations allow for budget control.
Membranes typically cannot withstand the process conditions on their own physical resistance properties. However, when membranes are correctly specified and protected from exposed process conditions with a combination of brick courses and mortar components – membranes become integral to the system.
