The Challenge AER-200 Respirometer System for anaerobic applications
The CHALLENGE AER-200 Respirometer System consists of one or more biological reaction vessels, gas flow measuring cells, and a computer. The gas measuring base contains eight flow cells and associated interconnecting circuitry. As gas flows through each cell under the influence of a slight pressure caused by gas production in the reaction vessel, bubbles of a fixed volume are formed in the lower ...

How is carbon dioxide gas measured?
Background Carbon dioxide gas is a gaseous compound produced by the reaction of carbon and oxygen. Its chemical formula is CO2. A carbon dioxide molecule consists of two oxygen atoms and one carbon atom. Carbon dioxide is an inorganic substance that is not flammable and generally does not support combustion. It is non-toxic at low concentrations, but when the concentration of carbon dioxide in ...

Tech Note: Flare Gas Measurement Innovation; Retain Flow Metering Accuracy Even if Gas Composition Changes
It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also known ...

LGD F200 - Designed for easy zeroing and span adjustments
Regular zeroing and span adjustments to gas analyzers in the field are suggested and required for a variety of reasons. Compliance to environmental standards, e.g. those outlined in the US EPA (40 CFR) or EN 14181 is an important factor. Special application conditions, e.g. a varying gas matrix or compensating for pressure effects can be additional reasons, where a zeroing and span adjustment ...

A matter of degrees
LumaSense Technologies’ E2T product manager, David Ducharme, explains why accurate temperature measurement is critical in a modified Claus sulphur reactor. There are two critical temperatures required for the safe and efficient operation of a sulphur furnace. The first is the refractory temperature, which is critical for hightemperature alarms and automated shutdown systems in the furnace. ...

Understanding the atmospheric measurement and behavior of perfluorooctanoic acid
The recently reported quantification of the atmospheric sampling artifact for perfluorooctanoic acid (PFOA) was applied to existing gas and particle concentration measurements. Specifically, gas phase concentrations were increased by a factor of 3.5 and particle‐bound concentrations by a factor of 0.1. The correlation constants in two particle–gas partition coefficient (KQA) estimation equations ...

Sub-metering of natural gas-flexible flow measurement delivers improved accuracy and substantial savings
Introduction Unlike oil, natural gas exists in abundance in the United States. Of the natural gas consumed in the United States in 2011,95% was produced domestically. The U.S. Energy Information Administration projects U.S. natural gas production to increase from 23.0 trillion cubic feet in 2011 to 33.1 trillion cubic feet in 2040, a 44% increase. Almost all of this increase in domestic natural ...

Detailed off-gas measurements for improved modelling of the aeration performance at the WWTP of Eindhoven
At wastewater treatment plants (WWTPs), the aerobic conversion processes in the bioreactor are driven by the presence of dissolved oxygen (DO). Within these conversion processes, the oxygen transfer is a rate limiting step as well as being the largest energy consumer. Despite this high importance, WWTP models often lack detail on the aeration part. An extensive measurement campaign with ...

An Alternate Method for Determining the Klinkenberg Correction
Gas slip phenomena in low-permeability media are typically accounted for by means of the conventional Klinkenberg correction. This correction is derived from gas permeability tests conducted under different pore pressures. An alternative method for obtaining the Klinkenberg correction is given which uses the results from gas permeability tests conducted with different gases under the same pore ...

Calibration of gas mixers in the low flow range
Most dynamic gas mixers use flow regulators to create defined gas mixtures. QCAL Messtechnik uses thermal mass flow controllers ( MFC ) from various, renowned manufacturers. These MFCs are reliably calibrated proven by a calibration certificate – traceable to National Standards. But these calibrations are limited. The whitepaper describes 2 methods to extend the application range of gas mixers ...
