  • Wastewater treatment plant monitors Greenhouse Gas emissions - Case study

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • So Your Greenhouse Gas (GHG) Monitoring Plan is Complete... Now What?!?

    U.S. EPA's Greenhouse Gas Mandatory Reporting Rule (GHG MRR) codified at 40 CFR Part 98 required that facilities subject to the rule have a complete written GHG Monitoring Plan by April 1, 2010. At a minimum, the GHG Monitoring Plan must identify (1) methods used to collect GHG emissions information and supporting data, (2) personnel responsible for collecting the data, and (3) quality assurance, ...

  • Typical process weighing applications

    Process weighing relates to the weighing of a powder material as part of a production process. The technology includes continually monitoring a material in a silo, discharging material by weight or rate, or even weighing products on the move. This article gives an overview of most of the typical process weighing applications that are used in all sorts of industries: level or inventory measuring ...

  • Electrofilter protection by fast monitoring of CO in flue gas – Case Study

    Electrostatic precipitators Many industrial operations produce exhaust gases that contain dust, fly ash (unburned constituents), fumes (including fine elemental particles such as cadmium, sulfur and lead) and mist (such as coal tar), which cause an unwanted impact to human health and the environment. One widely used method of removing such contaminants from a gas stream is to use an ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • Generator gas analyzer for monitoring of hydrogen cooled turbo generators

    Hydrogen cooled generators require safety measures that reliably prevent the formation of explosive gas mixtures during normal operation as well as maintenance periods. Thermal conductivity technology based gas analyzers are used for that task. A standardized CALOMAT 6 analyzer system - Set GGA - has been especially designed for this measuring task. Regarding redundancy and explosion ...

  • Controlling the addition of Chlorine into a Process

    There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...

  • Co-Metabolic Processes

    Introduction: Co-metabolism is one form of secondary substrate transformation in which enzymes produced for primary substrate oxidation are capable of degrading the secondary substrate fortuitously, even though the secondary substrates do not afford sufficient energy to sustain the microbial population. An emerging application involves the injection of water containing dissolved primary ...

  • Process analytics throughout the entire natural gas pipeline supply chain – Case Study

    Natural Gas (NG) Natural Gas is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful by products into the air. While natural gas is formed primarily of methane, it can also include smaller amounts of higher ...

  • Process & Emissions Optimization - Case study

    There are many locations that should be measured and monitored with a portable emissions analyzer to maximize product quality, combustion efficiency, safety, and emissions reduction in a cement plant including the following: Rotary Kiln gas outlet O2, CO, NOx, CO2, SO2, CxHy, temperature ...

  • Maxum process gas chromatograph measures and optimizes synthetic rubber production – Case Study

    Rubber Rubber is a collective term for macromolecular substances of natural rubber (NR) or synthetic rubber (SR) origin. Natural rubber use dates back to the Mayas but was first recognized as technical material in 1851 by Charles Nelson Goodyear. He presented a new material produced from the milk of rubber trees, which had been treated with sulfur and vulcanized to strengthen the ...

  • Wastewater Plant Relies on Thermal Flow Meter for Co-Gen Power Gas Blending Process
