Different methods to isolate process line from process instrument.

How to isolate a process line from process instrument with a DBB valve

Block and Bleed and Double Block & Bleed isolation systems are used in process instrumentation to isolate your instrument from the main process line. The isolation valve(s) stop the flow from the upstream, while the bleed valve removes any pressure or residual product that remains in the downstream section or in the section between the two valves.

Use of block and bleed valves is mandatory in many industrial processes for isolating the measuring instrument from the process line. This allows maintenance work to be performed on the instrumentation without the need to shut down the entire operation. There are two approaches to the installation of a block and bleed or a double block and bleed setup.

Mechanical engineers discuss a Power-to-X application.

What is the significance of the VDMA network “Power-to-X for Applications” for mechanical & plant engineering?

This year marks the 130th anniversary of the Mechanical Engineering Industry Association (VDMA). A one-of-a-kind group uniting the mechanical engineering industry. In celebration, we talked to a dear colleague and member of the VDMA network “Power-to-X for Applications”, Björn Bofinger.

Get ready to be surprised by the enthralling insights he shared. If you don’t know much about the VDMA network “Power-to-X for Applications”, this is your intro! Now, let’s find out how the network supports the mechanical and plant engineering industry in meeting today’s and tomorrow’s challenges when it comes to power-to-X applications.

Green sustainable icon with chemical plant complies with TA-Luft amendment in the field of valves.

New chemical plant complies with the stricter TA-Luft amendment in the field of valves

The amended Technical Instructions on Air Quality Control (TA-Luft) regulation came into effect on December 1, 2021. The updated regulation specifies stricter new limits for fugitive emissions from chemical plants. This is a tough challenge for the chemical industry.
In my article, I describe a case study of the challenge engineers faced in selecting compliant valves when building a new chemical plant in Germany.

Hydrogen molecules with EU stars stand for interview with Dr- Kantz regarding European Hydrogen Union.

Future importance of Hydrogen & Power-to-X in industrial applications at the EU level

Welcome to today’s interview! It features an insightful conversation I had with Dr. Carola Kantz, deputy managing director and a valuable member of the VDMA “Power-to-X for Applications,” on the future importance of hydrogen and Power-to-X (P2X) in industrial applications at the EU level.

The topic breaks down into four chapters and touches the core areas of interest with explicit description: (1) Hydrogen in the context of Power-to-X; (2) Legislations for climate protection; (3) Building a hydrogen economy; (4) Involvement of the mechanical & plant engineering sector.

TA-Luft amendment – What will change for you as a plant planner and plant operator in the area of valves

The Technical Instructions on Air Quality Control or TA-Luft governing Germany’s industrial plants were recently updated. The goal of the TA-Luft is to reduce emissions and improve air quality.

In this article I will give you an overview of the TA-Luft amendment and explain the specificities and requirements applicable to industrial valves. Furthermore, I analyze the changes to the old TA-Luft to identify challenges and solutions.

Plant operators and plant planners can’t miss out on this info to run compliant facilities.
