Chilean Copper Producer Need for Improved Raw Material Flow Measurement

Emerson’s Michael Pearson, part of the metals and mining industry team from a Rosemount measurement perspective, shares a story of a Chilean copper producer. This producer needed a way to improve monitoring the flow of raw material inputs in their production process.

With copper prices fluctuating regularly, many downstream metal processing facilities are faced with a growing number of challenges. Pressure to increase throughput and reduce costs is growing, and many plants lack the measurement infrastructure needed to effectively achieve these demands.

In many cases, measurement points were never engineered into the original plant. In other cases, measurements have been added, but without real-time monitoring or any effective way to get the measurements back to the control room. These non-existent and “stranded” measurements can often cost companies thousands of dollars in non-optimized processes and wasted resources.

Advances in wireless technology have enabled many operations to gain the additional insight needed to track their resources better. The best part is that use of wireless drastically cuts. In a previous post, I mentioned the story of Barrick Zaldivar, who added wireless flow measurements to their leaching pads to improve operational performance and business results. Now, I’d like to tell you about another producer who is incorporating wireless flow technology.

This Chilean copper producer operates a facility, which produces over 300,000 tons of cathode copper and 200,000 tons of precious metals, in addition to copper concentrate and acid. In an effort to reduce raw inputs to their processes they desired to monitor flow of a variety of resources, namely, diesel, air, oxygen, nitrogen, natural gas, water and purified water.

The company had many challenges in these flow measurements. Either the measurement points did not exist or they had power in place but no way to integrate the measurement data into their control system. To overcome these issues, the company worked with the Emerson team on ways to incorporate wireless measurement devices. The copper producer’s project team worked with the Emerson wireless application team to incorporate these IEC 62591 WirelessHART devices:



By incorporating these additional measurements, the copper producer now has a real-time view into the use of the raw material inputs. This view provides their engineers an opportunity to optimize their use by reducing their consumption. This helps to increase the efficiency of the overall production process.

Now that wireless technology has proven itself effective and positively impacting efficiency, I think we will see more and more mining companies looking to this technology to help optimize operations and solve real problems.

Social Media and Communities in Asia

I’ll be doing fewer blog posts this week as I travel around many of the Emerson Asia offices sharing ideas on social media and communities.

While in Qingdao, China last week, I had the opportunity to meet Emerson’s Major Chu, who has a highly successful Emerson Flow blog written in the Mandarin language. As social media does so well, it felt like I already knew Major well, before we met face-to-face for the first time.

The team in China has recently opened a Chinese-language community inside the Emerson Exchange 365 community. We hope to see additional languages come online over the next year.

This week, I’m visiting several of the Emerson offices in India.

I hope everyone has a great week and I’ll return to a normal posting schedule next week.

Another Bust in Solar Power

Emerson’s Alan Novak, who leads the alternative energy industry team, describes the continued downward economic pressure on solar power panel manufacturers.

Emerson's Alan NovakIn several previous posts, we’ve discussed the challenges facing solar panel manufacturers due to both declining panel prices and the uncertainties of government subsidies (usually in the form of feed in tariffs, or above market rates paid for excess solar power supplied to the electrical grid). They are not unrelated issues: as cheaper solar panels become available, more people install them, which leads to greater than expected demand for the subsidies. Given the current state of economies around the world, these subsidies are coming under increasing pressure.

The latest example of this interaction comes from the UK which has offered generous feed in tariffs for installers of small (<4kW) solar panel systems.

As the price for panels has dropped

Requiring a reduction in subsidies and sending the industry into another “bust”:

From: www.guardian.co.uk/environment/2012/may/01/solar-panel-demand-subsidy-cut

As highlighted recently in The Guardian article on this subject, solar PV installations have dropped nearly 90% since the government halved the subsidy offered for solar power on April 1st.

This lack of consistent policy is one of the major factors affecting development throughout the alternative energy industry. Policies (mandates, subsidies, etc) which are adjusted as administrations change, or even year to year as economic conditions dictate, make it very difficult to attract investment capital or create long term business plans.
