Tank Tales - 4 cases of failures, damage and inspections of storage tanks
By John Butterfield | 09 November 2020
Some tank failures are well known by the public: 1. The distilling tank with molasses, which killed 21 in Massachusetts in 1919; 2. The Bhopal tragedy in 1984, where people were exposed to methyl isocyanate gas with 3787 or more deaths; 3. The sulfuric acid storage tank failures in 2001 in Delaware City , where one person was killed, eight others were injured, and significant damage ensued to aquatic life.
Correctly specifying materials in chemical process industries
By John Butterfield | 02 November 2020
The rapid failure of several 316 stainless steel pipes in a heat exchanger raised questions as to whether a manufacturing fault or service conditions were to blame. This second in a series of three case studies conducted by Dr. Elayaperumal examines the corrosion of stainless steel tubes in chloride solution and why duplex would have been the best material of choice.

A new way to manage aging, leaking tanks
By John Butterfield | 12 October 2020
It is crucial to stay up-to-date with the upgrades and repairs required for tanks containing combustible fluids. Depending on how long a tank has been around, it can be more susceptible to leaks. This means it could need regular patching. While traditional methods for repairing tanks may provide a fix, it is only a temporary one.

Challenges for butterfly valves in solar thermal systems
By John Butterfield | 14 September 2020
The four offset butterfly valve from the manufacturer Quadax is used worldwide in solar thermal systems and offers important advantages in terms of reliability and cost efficiency. The number of solar power systems is increasing worldwide: Back in the mid-eighties, when the first solar plants went into operation in the Californian desert, they had a capacity of just 350 MW. However, thanks to technical innovations, solar systems now achieve a capacity of 3,000 MW.
Getting more out of assets
By John Butterfield | 07 September 2020

Estimations consider most – at least more than 60% – of existing pipelines to be older than 45 years by now. Already in 2002 according to the large-scale 2-year study in the United States the annual costs alone in the U.S. were estimated at approx. $7 billion dollars to monitor, replace and maintain gas and liquid transmission pipelines.
Plant modernization in the metal industry
By Roy van IJzendoorn | 10 October 2017
‘Virtual commissioning’ provides the possibility of testing and verifying the perfect functioning of automation systems and optimizing controls and process steps before the ‘real’ commissioning takes place in the metal industry. Various successfully accomplished projects at the Gienanth iron foundry in Eisenberg, Germany, have demonstrated that commissioning times can be markedly reduced by simulating the equipment and functions beforehand – in a ‘digital factory’.
