Aerodynamic noise attenuation in rotary control valves

Are rotary control valves a good choice to be used in dampening aerodynamic noise? Here’s what our expert blogger Ville Kähkönen explains.

FCCU in today’s refineries

Fluid Catalytic Cracking process is one the most profitable and flexible processes in today’s petroleum processing.

Things to consider in valve selection for catalytic cracking

Reliable and accurate control, on-off and ESD-valve performance is important for total process efficiency, productivity and safety. Here’s presented some of the key-applications and things to consider in selecting valves for a typical FCCU.

Keep the noise down - Rotary valve noise abatement in gas and steam flow control applications

Noise can be a problem in even low and medium pressure steam applications, resulting in issues like heavy vibrations or health, safety and environmental hazards.

Butterfly valve installed, problem solved - Reducing Dow’s operational costs under extreme process conditions

The Dow Chemical Company has been operating in Stade, Germany for more than 40 years. Nearly three million tons of basic and specialty chemicals are manufactured per year in this ultramodern integrated plant complex, placing high availability and safety demands on all components. That’s why Dow has installed a custom-designed butterfly valve, developed by Neles, to reliably shut off the DME reactor in Stade.

Fugitive emission control creates site efficiency

From end-user point of view, perhaps even more important than the selected standards and simple compliance with ever-tightening environmental regulations, are the other benefits provided by the low fugitive emission valve designs.

Improving process safety and cutting costs with process ball valve

How can a properly designed process valve extend plant availability and reliability?

Optimizing valve maintenance using condition analysis

Typically in shutdown situation the amount of valves to be maintained is limited in order to meet maintenance budget. Valve maintenance can be optimized by using condition analysis to focus maintenance actions to only devices needing attention.

Achieving better accuracy in flow control with a unique plug shape

Although Finetrol belongs to the eccentric plug valve category (IEC 60534-1 Sect 3.1.2.5), it has design differences that distinguish it from other eccentric plug valves currently available on the market. One of the special design features is a balanced plug that delivers benefits when it comes to better accuracy in flow control.

Understandable valve diagnostics

Digital valve controllers can provide diagnostic data about the valve assembly. But how many users can correctly interpret the data they get?
