‘On-site calibration — doing more with less’

Day-to-day activities, such as carrying out maintenance or emergency repairs, commissioning new equipment or conducting on-site checks, need to be simplified because of the reduction in personnel and increase in workload. As this guide from GE Measurement & Control explains, use of the most advanced on-site instrumentation is imperative in order to maintain and calibrate today’s intelligent, high-precision equipment; this aspect applies to all process applications.

Hi Pollution Monitoring In Cement Industry!.

Hi Pollution Monitoring In Cement Industry!.

The rising use of waste based fuels in the cement industry, both for economic and Environmental objectives, combined with the strengthening of air emission regulations around the world is pushing many operators to face a wider list of pollutants to monitor this, with associated costs. 

The design of appropriate solutions meeting local regulation is the key to maximize the cost benefit of the fuel while maintaining good relationships with local authorities and populations.

Besides the usually requested parameters, like SO2, NOx, CO, total particulate matter, and NH3, additional parameters can also be measured such as HCl, HF, Dioxins & Furans (PCDD/PCDF), Mercury (Hg) and VOC/TOC.

The monitoring of each gas pollutant, when required, can pose specific difficulties, but in general keeping the cost low means trying to operate a multi components analyzer able to measure all of them, except Dioxins & Furans and Mercury which requires very specific technologies and dedicated sampling devices.

Various manufacturers have developed a broad range of analyzers and sampling systems dedicated to meet cement operator needs according to their local regulation. 

Some of these solutions are described below:

The MIR 9000H developed by Environnement S.A (France) is a new generation of heated NDIR analyzer able to simultaneously measure  traditional components such as NOx, SO2, CO, CO2 and O2, in addition to H2O and pollutants like NH3 and HCl, representing a very cost effective, turnkey solution. 

This analyzer was designed to be operated without any chiller, drying membrane, or catalytic oven, allowing the flues gas directly into the measurement cell without any kind of disturbance. 

The entire system being heated to 180°C (~360°F), no condensation can occur even in extremely wet conditions with up to 40% moisture. 

This analyzer’s robust design is particularly suited to demanding wet stack gas mixtures, including those with potentially high NH3, HCl and HF content. Indeed, this analyzer is completely immune to NH3, HCl and HF: both its integrity and its metrological performances being unaffected.

As a cost effective heated analyzer, the MIR 9000H is also an ideal solution for process control to monitor ammonia slips in SCR/SNCR processes. 

In these processes, either ammonia or urea can be used. It is important to stress out that in the case of urea, MIR 9000H takes into account the N2O which is created as a by product. MIR 9000H can also cope with formaldehyde, a compound which can be produced with some types of fuels and cause problems to NDIR measurements.

For low SO2, HCl or NOx concentrations, the SEC-MIR9000 system combining an exclusive membrane based drying technology (sampling) and state of the art NDIR multigas analyzer remains the perfect solution.

It allows for the measurement of a wide range of pollutants, including also CO, CO2, HF and TOC, as well as N2O and formaldehyde for interference corrections purposes.

The SEC-MIR9000 system, while being technically speaking an extractive system, also exists as an in-sit setup (MIR IS). 

Very low NOx concentrations can also be measured with a chemiluminescence CEMS bench, either as an option of an NDIR system, or as a standalone analyzer.

FTIR: Environnement S.A was the first company to introduce the FTIR technology for CEMS application and remains a leader. 

This technology allows the monitoring of a wide range of pollutants, including SO2, NOx, CO, CO2, NH3, HCl, HF and VOC/TOC, with low measurement ranges, making it the ideal solution for the strictest regulations.

Dioxin is an increasing source of suspicion by neighbour populations in regards to waste or alternative fuels combustion. 

The AMESA-D continuous sampler allows for a continuous coverage of dioxin emission and is already considered the standard for monitoring dioxins/furans around the world.

Beside the emissions of PCDD/PCDF there are other emissions of compounds which are not or not so easy to be monitored continuously. 

E.g. mercury can be monitored continuously, but for plants with low concentrations in the range of µg/m3 the accuracies of the existing mercury CEMs depend very strong on the experiences and maintenance efforts of the operators. 

Otherwise the results are not accurate enough. Additional the availability of such systems is restricted.

The continuous Hg Sorbent Trap Measurement System (STMS) AMESA-M represents a cost effective alternative to mercury analyzers, especially when the limit or detection is low and that complex and expensive technologies are necessary. 

The system is based on the adsorption trap method described in the performance specifications 12B of the MACT standard for the continuous monitoring of mercury emissions and is suitable for nearly every application.

The AMESA-M system requires very low maintenance and is adapted to the different flue gas conditions and requirements given by the operators: its availability under difficult flue gas conditions could be kept by values of almost 100 %.

Hi ‘Eight things to consider when choosing an outdoor humidity instrument’;

Outdoor humidity and temperature measurement is essential for applications such as energy management and indoor climate control. Just one outdoor humidity sensor typically optimises the energy efficiency of cooling equipment. However, if this sensor is not accurate, both energy efficiency and human comfort may be compromised. This application note from Vaisala discusses using solar radiation shields; guidelines for installing outdoor humidity instruments; the elements of a good radiation shield; the most common humidity parameters used in free cooling; and more.

(Hi) - EPA, U.S. to Cut Carbon Pollution from Existing Power Plants!.

(Hi) - EPA, U.S. to Cut Carbon Pollution from Existing Power Plants!.

The Clean Power Plan is a proposal to ensure a healthier environment, spur innovation and strengthen the economy.

After a major outreach effort, the EPA is releasing the Clean Power Plan proposal to cut carbon pollution from existing power plants, the single largest source of carbon pollution in the United States.

The proposal will protect public health, move the United States toward a cleaner environment and fight climate change while supplying Americans with reliable and affordable power.

"Climate change, fueled by carbon pollution, supercharges risks to our health, our economy, and our way of life. EPA is delivering on a vital piece of the Climate Action Plan by proposing a Clean Power Plan that will cut harmful carbon pollution from our largest source--power plants," said EPA Administrator Gina McCarthy. 

"By leveraging cleaner energy sources and cutting energy waste, this plan will clean the air we breathe while helping slow climate change so we can leave a safe and healthy future for our kids. We don't have to choose between a healthy economy and a healthy environment--our action will sharpen America’s competitive edge, spur innovation and create jobs."

Power plants account for roughly one-third of all domestic greenhouse gas emissions in the United States. 

While there are limits in place for the level of arsenic, mercury, sulfur dioxide, nitrogen oxides and particle pollution that power plants can emit, there are currently no national limits on carbon pollution levels.

With the Clean Power Plan, EPA is proposing guidelines that build on trends already underway in states and the power sector to cut carbon pollution from existing power plants, making them more efficient and less polluting. 

This proposal follows through on the common-sense steps laid out in the Climate Action Plan and the June 2013 Presidential Memorandum.

By 2030, the steady and responsible steps EPA is taking will:

• Cut carbon emission from the power sector by 30 percent nationwide below 2005 levels, which is equal to the emissions from powering more than half the homes in the United States for one year.

• Cut particle pollution, nitrogen oxides and sulfur dioxide by more than 25 percent as a co-benefit.

• Avoid up to 6,600 premature deaths, up to 150,000 asthma attacks in children and up to 490,000 missed work or school days—providing up to $93 billion in climate and public health benefits.

• Shrink electricity bills roughly 8 percent by increasing energy efficiency and reducing demand in the electricity system.

The Clean Power Plan will be implemented through a state-federal partnership under which states identify a path forward using either current or new electricity production and pollution control policies to meet the goals of the proposed program. 

The proposal provides guidelines for states to develop plans to meet state-specific goals to reduce carbon pollution and gives them the flexibility to design a program that makes the most sense for their unique situation. 

States can choose the right mix of generation using diverse fuels, energy efficiency and demand-side management to meet the goals and their own needs. It allows them to work alone to develop individual plans or to work together with other states to develop multi-state plans.

Also included in the proposal is a flexible timeline for states to follow for submitting plans to the agency—with plans due in June 2016, with the option to use a two-step process for submitting final plans if more time is needed. States that have already invested in energy efficiency programs will be able to build on these programs during the compliance period to help make progress toward meeting their goal.

Since last summer, EPA has directly engaged with state, tribal and local governments, industry and labor leaders, nonprofits and others. 

The data, information and feedback provided during this effort helped guide the development of the proposal and further confirmed that states have been leading the way for years in saving families and businesses money through improving efficiency, while cleaning up pollution from power plants. To date, 47 states have utilities that run demand-side energy efficiency programs, 38 have renewable portfolio standards or goals, and 10 have market-based greenhouse gas emissions programs. 

Together, the agency believes that these programs represent a proven, common-sense approach to cutting carbon pollution—one in which electricity is generated and used as efficiently as possible and which promotes a greater reliance on lower-carbon power sources.

The announcement marks the beginning of the second phase of the agency’s outreach efforts. 

EPA will accept comment on the proposal for 120 days after publication in the Federal Register and will hold four public hearings on the proposed Clean Power Plan during the week of July 28 in the following cities:

Denver, Atlanta, Washington, D.C. and Pittsburgh. Based on this input, EPA will finalize standards next June following the schedule laid out in the June 2013 Presidential Memorandum.
