What Is Refractory Removal?
Refractory removal is a critical step in maintaining the performance and safety of furnaces, kilns, boilers, and reactors. At Silver Raven, we utilise advanced high-pressure water jetting and mechanical methods to safely remove refractory linings without damaging underlying structures. Our non-destructive techniques minimise dust, vibration, and downtime while ensuring thorough preparation for relining or maintenance. By combining precision equipment with certified expertise, we deliver safe, efficient, and cost-effective refractory removal that protects assets and enhances operational reliability.

Benefits of Refractory Removal Service
Safety has been the principle motivator in the changing approach to improve methods for removing coked refractory from FCCU’s. The revolutionary Silver Raven remotely controlled blasting system has been designed primarily to provide a safer method for removing coke impregnated refractory from inside refinery reactor risers. The system can also be used in numerous similar applications where it is necessary to remove spent refractory linings or hard deposits from vessels or pipes.
The Fluid Catalytic Cracking Unit (FCCU) is one of the most important facets of an oil refinery. This paper seeks to explain the advantages of using a new technology that steps beyond the current archaic use of jack hammers to remove coked refractory from the inside of FCCU Risers.
In Fluid Catalytic Cracking Units (FCCU), risers and components are built from carbon steel lined with refractory material typically 25mm thick, but up to 125mm in high-stress areas. These linings resist high temperatures (~700°C), corrosion, and insulate the steel shell. Over time, coke deposits from cracking reactions impregnate the refractory, compromising insulation and flow conditions. Linings must be replaced every 4–8 years. Traditionally, jack hammers are used to remove refractory, but this method is slow, dangerous, and often damages the steel and hex mesh. The extreme hardness of coke-impregnated linings (150–170 MPa) can make removal nearly impossible, sometimes requiring entire FCCU sections to be cut and replaced an expensive process that prolongs costly refinery shutdowns.
