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.

Cooling down a reactor for process reliability
There are a great number of polyolefin reactors available, each with having their own advantages and disadvantages in polyolefin production. Therefore, efficient heat removal remains a key concern in the design and operation of the polyolefin reactors.
Sizing success with Nelprof – unlocking butterfly valve potential
Valve sizing is a critical step for achieving precise, reliable and stable flow control as well as improved process performance, especially when using Valmet’s butterfly valves in demanding control applications. Butterfly valves are valued for their compact design and versatility, but their performance depends heavily on correct sizing and selection. This is where Valmet’s valve sizing and selection software, Nelprof™, makes a real difference.

How to improve turbine efficiency
In the power and gas turbine market, competition among turbine and compressor manufacturers has become more challenging. Decisions are driven mainly by price and efficiency. Saving costs by selecting the correct application-based control and safety valves has become more important. New valve technologies and new valve designs help increase turbine efficiency and reduce costs while improving safety, for example, by installing a faster pressure relief in the case of a trip in a compressor or a gas turbine compressor.
