Fuel Heating Value Determination

The heating value and other properties of fuel gases, such as natural gas and biogas, can vary significantly with time and both gas suppliers and their customers may need to know the heating value of a supply on a periodic, such as monthly, or on a spot basis.

 ORTECH provides a heating value and natural gas property determination service to a number of our clients and is certified separately by Measurement Canada to carry out these determinations on both natural gas and biogas.  These determinations require the analysis of methane in a sample but also the composition including analysis of fixed gases and trace amounts of other hydrocarbons which may contribute to the overall heating value.  Generally, Gas Producers Association and ASTM methods are used.

 Landfill Gas and Biogas Analysis

Heating values, gas composition and the physical properties of landfill gas and biogas are determined in the same way as they are for natural gas, although these gases primarily contain methane, carbon dioxide and air compared with natural gas which is principally methane.  ORTECH can also conduct extensive field or laboratory sampling and analysis of these gases for all types of contaminants both before and after combustion.

 Natural Gas Analysis

In addition to determining the heating value of natural gas based on the analysis of fixed gases and hydrocarbons, ORTECH can determine the physical properties such as moisture content, sample pressure, air contamination, density, specific gravity, Wobbe Index, gas compressibility and condensation temperatures.  Additional analyses of contaminants in the natural gas which may affect pipeline distribution, pipeline corrosion, deterioration of combustion equipment and combustion characteristics include reduced sulfur compound odorants, particulate matter, metals, siloxanes and condensable organic material.  The analysis for specific organic chemicals enables the condensation dew point to be calculated.

Fixed Gas Analysis

ORTECH specializes in the sampling and analysis of fixed gases (oxygen, carbon dioxide, carbon monoxide, nitrogen, permanent gases and moisture primarily) in a variety of processes and products.  Examples are the assessment of consumer products such gas detectors and the analysis of off-gassing samples.

Another example is the continuous field sampling and analysis of these gases from combustion sources at industrial facilities, coal-fired generating stations, incinerators, cement plant and steel works.  These programs may also include sampling and analysis of related gases such as sulfur dioxide, hydrocarbons and nitrogen oxides as well as the certification of plant analyzers used for greenhouse gas monitoring and reporting.

Biomass/Biogas Analysis

With increasing emphasis on the use of biomass as both a source of energy and as a nutrient such as the application of manure on agricultural fields, regulations require that the biomass is sampled and analyzed before it is used.  These analyses may include an odour evaluation to determine the odour release potential or analysis for specific hazardous contaminants such as metals and pathogens.

ORTECH has the expertise to collect biomass samples based on standard protocols and manage the required analytical programs either in their own laboratories or in laboratories which have expertise with specific contaminants.

Sample Collection

ORTECH has extensive experience in the collection of natural gas, landfill gas and biogas field samples for analysis.  This includes sampling at high pressure gas mains which enter facilities such as industrial plant and gas turbine generating stations.  These facilities require strict adherence to safety procedures and a thorough knowledge of how the samples should be collected based on the analyses required.  If preferred, ORTECH can provide the equipment and training to allow staff at the facility to collect and ship the samples to ORTECH for analysis.

Reduced Sulphur Compound Analysis

Reduced sulfur compounds are frequently responsible for odour complaints from facilities such as sewage treatment plants, steel works, pulp & paper mills, and composting.  Some of these compounds are added to natural gas, which otherwise has no odour, so that dangerous leaks can be detected by odour.  For each of these situations ORTECH can collect air samples and analyze them in the laboratory for a series of reduced sulfur compounds which include hydrogen sulfide, carbon disulfide, mercaptans, organic sulfides and thiophenes.  Portable field analyzers for hydrogen sulfide analysis are also available.  In many cases the emissions of reduced sulfur compounds can be correlated with odour emissions and the potential for odour complaints assessed.

ORTECH has provided Material Testing services for over 30 years.

Our services include the direct analysis of materials for a variety of chemical and physical components as well the collection of off-gas samples from the materials followed by analysis for volatile compounds and odour.

  • Off-Gas Testing of Materials: Consumer and related products frequently discharge volatile organic compounds and other volatile compounds into the air during a process called off-gassing, particularly when these products are new. Examples are furniture and fabrics which can cause health problems in households or the workplace.  ORTECH uses various techniques to collect these compounds either on-site at residences, offices and other locations or in the laboratory using material samples.  Once the air samples have been analyzed the results can be compared with indoor air quality standards and guidelines to confirm if the discharges may be the cause for concern from a health perspective or the source of unpleasant odours.
  • Fuel Gas Testing: ORTECH has a laboratory which is dedicated to the analysis of fuel gases for major components (methane, carbon dioxide, nitrogen, moisture, oxygen) as well as for minor components (other hydrocarbons, reduced sulfur compounds, carbon monoxide) and physical properties (heating value, compressibility, density, Wobbe index).  These fuel gases include natural gas, landfill gas and biogas from sources such as the anaerobic digestion of biosolids.
  • Odour Release Potential of Materials: Odours may be released from a variety of industrial, commercial and consumer products. Frequently there is a need to quantify these odour emissions so that the material can be modified or reformulated to reduce the odour impact. Examples are the reformulation of paint at an automobile paint facility to address off-site odour complaints or to prevent packaging material odours from contaminating food products. Odour testing may also be conducted on merchandise recovered from a fire or flood to determine if it can be salvaged.  Samples for odour evaluation may be recovered from the material using a variety of techniques. Evaluation of the samples involves a determination of the odour detection threshold value and other odour parameters using an odour panel with an olfactometer. An odour panel is a group of six or more people screened to have a “normal” level of odour sensitivity and who are trained to assess odours. An olfactometer is a scientific device which is used to accurately dilute an odorous sample before it is presented to the panelists.
  • Biomass Material Sampling and Analysis:  To comply with new and existing legislation in Ontario and elsewhere, ORTECH undertakes sampling and analysis of various biomass materials.  Examples are materials which must be analyzed include those specified under Ontario Regulation 267 to determine the odour classification of non-agricultural source material used as a nutrient for land application and Ontario Regulation 101 to determine the classification of municipal compost.
