Fluid catalytic cracking (FCC) process is one of the most profitable processes at today’s refineries. However, high temperatures and corrosive medium can quickly turn a profitable process into a plant-wide downtime nightmare. As a dependency for downstream processes, reliability in the FCC is a must.
Increased uptime at extreme erosive condition
Relentless commitment on safety
Seamless conversion to intelligent digital positioning saves time and money
Reliable partner for FCC revamping
Reliable valves and services for fluid catalytic cracking
Erosion and abrasion caused by catalyst fines
FCC process steps (converter, flue gas, main fractionator, regeneration and vapor recovery) all present different challenges that require unique solutions. However, all require erosion resistance, control accuracy, rangeability and uncompromising reliability especially in safety-critical locations.
The slurries used in the FCC process are erosive. Valves that are poorly designed or use less than ideal materials of construction will wear quickly causing dangerous conditions and downtime.
Metalurgy, coatings and seat design make the difference between uptime and downtime
The FCC process is hot and abrasive. In order to achieve the greatest performance and uptime we focus on delivering the exact right material selection and trim coating materials. Our proprietary seat design is proven to reduce the collection of solids and keep valves operating reliably longer than the competition.
Neles™ has been developing severe service valves for more than 60 years. That experience helps to create operational efficiencies that minimize catalyst expenditures. Also, most critically, the valves are proven to stand the test of time allowing your refinery to operate safely and in compliance with environmental regulations.
Neles provides valves for traditional FCC designs proven to adeptly handle extremely erosive conditions. We also work with refineries at the cutting edge to revamp FCC units into residual FCC’s in which the challenges of heavier feedstock and all around more extreme service conditions must be overcome.
Accuracy and reliability in the most demanding applications
At Neles your investment is our responsibility. We provide severe service valves built without compromise to protect your process integrity and increase productivity and safety.
