Monitoring the oxygen content in bio-methane-to-grid supply

Orbital utilise the EC91 ATEX oxygen analyser from Systech Illinois to accurately monitor the oxygen content in the purified bio-methane gas prior to it being injected into the national grid gas network In September 2010, Orbital installed the gas monitoring and treatment plant on the UK’s very first large-scale bio-methane-to-grid production facility. This site was designed specifically ...

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 ...

Some notes about Fats and Oils in Food and about FAME and FAMEWAX

In Europe, the last transition periods named in REGULATION (EU) No 1169/2011 on the provision of food information to consumers are running out on Dec. 13th, 2016. Since then, a nutrition declaration is mandatory for nearly all packed food in Europe, wherein the amounts of fat, saturates, carbohydrate, sugars, protein and salt have to be included. The content of the mandatory nutrition declaration ...

Development of headspace–gas chromatography–flame ionization detection procedure to determine volatile fatty acids in zoo organic waste leachates

In order to determine volatile fatty acids (short chain monocarboxylic acids with 2 to 6 carbon atoms in a molecule) in leachates formed in organic waste piles a procedure based on static headspace (HS) coupled with gas chromatography (GC) have been proposed and optimized. The conditions of HS extraction and sample introduction into a gas chromatograph as well as of chromatographic separation ...

Sample conditioning issues emissions monitoring from combustion processes

ABSTRACT Preventing condensation within gas samples is important if accurate measurement of a soluble component is required - principally nitrogen dioxide within combustion products. Maintaining gas samples above the water or acid dew point is normally achieved by heating the sample transfer lines and gas analyser modules. This paper presents simple methods for the dew point calculation of ...

Pilot scale facility to determine gaseous emissions from livestock slurry during storage

Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...
