Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study

During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

Tech update: Plant instrumentation - food engineering

Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

New monitoring technology helps reveal Arctic secrets

A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

Japanese Organics Recycling Association Formed

Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

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 ...
