In todays environment of security awareness there is a heightened concern over maintaining the integrity of plant operations.
The causes of undesired interference with plant and industrial installations ranges from plant operator ignorance or error to vandalism and then the ultimate concern, terrorism.
Equipment behind a plant’s security fence is less vulnerable than equipment on a remote installation, like an unmanned pump station for example. However, the desire to reduce interference from all causes, warrants consideration of all potentially vulnerable devices.
The valves used in a plant are particularly important devices. Opening or closing a valve at the wrong time could cause a catastrophic leak, contamination or hazardous situation that may put personnel and equipment at risk.

The BP refinery in Whiting, IN has 80,000 valves in its leak detection and repair (LDAR) program. There are approximately 20 process units in the refinery, on an average five-year-turnaround cycle and 200-300 valves on every turnaround work list. BP executed an EPA consent decree in 2012 and has been working on improvements around LDAR and emissions since 2011.

More than 93% of Edmonton, Alberta’s nearly 880,000 residents recycle, keeping 60% of waste out of the landfills. But that wasn’t good enough for this city, which prides itself on its environmental efforts. So, in its efforts to find a way to divert even more of that waste and reduce CO2 emissions, the city worked with Enerkem and the provincial government (Alberta Innovates – Energy and Environment Solutions) to create the world’s first industrial-scale facility to produce biofuels from municipal solid waste. Inaugurated in June 2014, this facility will make it possible for the city to achieve a 90% conversion rate by 2016, by turning trash into methanol and ethanol. While other municipalities have been able to convert waste into power, to date there is no other industrial-scale facility that turns waste into biochemicals.

At VMA’s annual Market Outlook Workshop held in Boston this past August, Glen Ives, chair of Deloitte Canada, reported on the state of the mining industry and the trends affecting its profitability and future.
“I am an economic bull,” he said. “I look at China and see an economy that's growing and will double in the next 10 years. I look at the U.S. and see an incredibly strong economy that the rest of the world underestimates. Latin America is also growing. I believe there will be continued economic growth across the globe, and that means increased commodity demand.”

In the U.S., regulations governing lead content of the components of potable water systems have seen considerable changes as safety restrictions tighten. The federal law in effect since January 2014 dictates much lower lead content for certain systems and components than in the past.
Manufacturers of potable water equipment and systems — including drinking water fountains, R/O (reverse osmosis) systems, coffee machines and commercial kitchen equipment — as well as equipment maintenance contractors, are affected. Many remain uncertain how the new regulations will impact their manufacturing and purchasing.
