Valves enhance fluidized-bed polymerization: Part 1 – Reactor cycle gas system

Valves have a critical role in ensuring that the fluidized-bed type of gas-phase polymerization is stable, flexible and controlled. Any valve leakage poses both an environmental and safety issue due to risk of fire, toxicity, and the volatility of gaseous hydrocarbons.

Cut turnaround costs by focusing maintenance where needed

One of the biggest challenges is determining what devices will be adjusted, repaired or upgraded, and ensuring that key devices are not ignored.

Breaking through the textile industry

Circulose dissolving pulp uses cellulose from discarded textiles that is then spun into soft and breathable new textile materials like viscose and lyocell. Renewcell and Valmet have worked closely on this groundbreaking innovation from the first pilot trials to the first-of-a-kind industrial-scale production line.

8 ways to lower the total cost of valve ownership

The concept of total cost of ownership (TCO) is not an unfamiliar term when discussing investment decisions in process industries. It has become a valuable tool to help buyers make more informed purchase decisions.

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.

Safe offshore production – part 3: processing information

There are efficient technologies available which can optimize the plant shutdown time as well optimize the needed visits in the platforms. Real time condition monitoring, using open technology asset management tools and analyzing the condition monitoring information works very efficient way and the following examples describes better this idea.

Fugitive emission standards – remedy or futility?

Plant owners are being forced to spend more time and money to stay in compliance with the lower emission mandates. Several reports state that 50 to 60% of emissions from a plant are attributed to external leakage from valves.

Is right valve for the process the next big innovation?

Is excellence in valve selection from huge market offering the next major innovation that process industry is calling for?

Over 50 years of valve controllers

Reliability and performance with 50 years of valve controlling experience.

Ensuring the highest performance

Many requirements for our products come from international standards and from customer specifications. The standards and specifications usually require demanding tests and a deep understanding of related issues. The primary focus of these requirements are safety, the environment and operational performance. The design and set-up for all this testing requires the development of unique and specialized equipment, as well as deep knowledge of process automation and data acquisition.
