How to eliminate erosion and abrasion caused by catalyst fines in FCCU?

This entry describes how an installed Neles erosion/abrasion resistant ceramic valve solution has helped a customer improve FCC unit performance and profitability. In this particular case eroding 2″ to 10″ valves in a refinery’s fluid catalytic cracking (FCC) unit were causing problems that degraded both productivity and profitability. Neles application engineers analyzed the problem and provided a solution that quickly paid itself back many times over.

Precise control with high vibration

A corn processing plant in the US was experiencing difficulties with a critical valve used for controlling fiber-laden corn syrup in its ethanol manufacturing process. Two factors in particular were making it tough to achieve consistent control.

Know your installed base like the back of your hand

Honestly, if you don’t know which field devices you have, where they are located and the job they are doing, then how can you expect to improve your equipment and plant reliability?

3 steps to ensure ESD valve reliability beyond certification

Final elements, such as ESD valves, are a critical part in the safety lifecycle. When they are not working properly, the safety of the entire plant is in jeopardy. To ensure overall plant safety, correct ESD valve selection plays a vital role. A lot of uncertainty prevails around the relatively new standards IEC 61508 and IEC 61511 and how they should be interpreted for safety valves. This blog post looks closer at this issue and sheds some light on what is an essential but confusing subject.

Gaining deeper insight to solve valve cavitation

Since cavitation is one of the most significant causes of wear, it is important to control the impact of the fluid flow. Using advanced computational fluid dynamics (CFD) to model cavitation helps you reach quicker, more efficient results and deeper insight for your designs, avoiding any premature failure of your control valves.
