Fugitive Dust

This article describes a new approach, which aims to create bespoke modelling methods that are more refined for site-specific predictions.

Measuring Oil in Produced Water

Separation and produced water re-injection or discharge forms an integral part of subsea processing strategy. Its wider acceptance within the oil and gas industry, however, will depend on the availability of a reliable and continuous measurement of the quality of the water being injected or discharged.

Flaring’s Burning Issues

Capturing flared or vented gas presents an opportunity for oil and gas operators to reduce environmental impact as well as providing the prospect of generating an additional revenue stream.

Arctic Metrology

The polar environment is under a constantly increasing interest: climate change comes first and comes faster in the arctic. Multitudes of observations are needed to understand the environment and its evolution. The traceability of data becomes fundamental for the comparability of the many and different measurements’ results.

The True Cost of Water

Without adequate water supplies and an understanding of the true value of water, many businesses would be incapable of operating. Defining the true value of water helps businesses make intelligent decisions regarding how they source, use, reuse and dispose of water in order to maintain profitable economics of operation.

Analytical Challenges

Benzene Monitoring

Environmental concerns continue to exert downward pressure on the detection limits of monitoring systems. Benzene, along with other aromatics, is coming under increasing scrutiny in the European Union, and the United States is also re-examining current permissible levels.

Chromatography - The Science of Separation [Jun 2010]

Chromatography is the science of separation, with the analyte of interest being in a mobile phase, passing through a series of stationary phases. This allows the analyte to be isolated for quantification through a wide variety of techniques. This article looks at how chromatography is used to separate the noble gas krypton from air.

Heavy Metals' Monitoring

Much of the focus on measuring heavy metals in the ambient atmosphere has been to establish monitoring sites at locations close to local sources of heavy metals in industrial and urban areas. However, there is also a specific legislative requirement to monitor heavy metals in rural areas where concentrations are considerably lower. The Rural Heavy Metals Monitoring and Deposition Network determines the concentrations of heavy metals in samples of ambient air and rainwater collected at remote rural sites across the UK, which are not unduly influenced by local sources of anthropogenic emissions. This article describes the operation of this monitoring network and how the data are used to determine background levels of heavy metals in the UK (and thereby demonstrate compliance of the UK with the relevant EU legislation for rural areas), and in the quantification of heavy metal deposition from the atmosphere.

Air Pollution - Monitoring Particulates

Clean air is an essential requirement for the health and wellbeing of both the human race and the environment we live in, but achieving it is a constant battle with air pollution. According to the World Health Organisation (WHO), more than two million premature deaths each year can be attributed to the effects of urban outdoor and indoor air pollution, a shocking statistic indeed.

Ammonia Sensors and Their Applications

According to the European Environment Agency (EEA), almost 10 million metric tons of ammonia are produced and used per year in Western Europe, making it one of the most common of all High Production Volume (HPV) industrial chemicals.

Continuous Emissions Monitoring

The topic of monitoring stationary sources emissions is very broad and many books have been published on the subject. This article is aimed at giving an overview of some of the techniques employed.

Equilibrium sampling in soil, snow and aquatic ecosystem measurements

This application note describes the equilibrium sampling method to be used with the Vaisala CARBOCAP® Carbon Dioxide Probe GMP343 for measurements of CO2 concentrations and fluxes in soil, snow or aquatic ecosystems. Some practical hints are provided for the different environments to ensure successful and trouble free measurements. This application note has been prepared in cooperation with Lammi Biological station, Department of Ecological and Environmental Sciences and Department of Forest Ecology at University of Helsinki.

Continuous Particulate Emissions Monitoring

The subject of Continuous Particulate emission monitoring to satisfy regulatory requirements is of relatively new interest as a result of recent changes in legislation. Historically regulators were concerned with the visual impact of the discharge from a stack and therefore emission limits were expressed in terms of colour or opacity. However with the advent of emission limits for a process being defined in terms of mass concentration (expressed in mg/ m3) the issue of continuous particulate monitoring has become a new and growing regulatory requirement.

Continuous Emissions Monitoring

There has never been such a wide range of analysers and systems available for continuous emissions monitoring from industrial processes as there is today. In the UK there are many manufacturers and distributors offering CEMS (continuous emissions monitoring systems) using a variety of technologies. These include Ultraviolet (UV) and Infrared (IR) absorption, Fourier Transform Infrared (FTIR), Differential Optical Absorption Spectroscopy (DOAS), chemiluminescence and photoacoustic spectroscopy (PAS) for gaseous species as well as various techniques for particulate monitors.

Advances in Sorbent Technology

Whether you are already using sorbents in some format, or whether this application is a new concept to you, it is interesting to see how the simple sorbent tube started out - the work and research involved to create a device many of us in the occupational hygiene field now take for granted.
