What are TVOC gases?
TVOC is a grouping of a wide range of organic chemical compounds to simplify reporting when these are present in ambient air or emissions. Many substances, such as natural gas, could be classified as volatile organic compounds (VOCs). VOCs are of concern as both indoor air pollutants and as outdoor air pollutants.
Does TVOC include natural gas?
Oil and gas industry VOC emission sources include: Storage Tanks – Crude Oil, Condensate and Produced water….THE ABCS OF VOCS.
| Volume of natural gas: | 500,000 | standard cubic feet (SCF) at 60°F & 14.7 psia |
|---|---|---|
| Gas stream VOC mass: | 4,007 | lbs |
What does TVOC stand for?
Total volatile organic compounds
Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants. If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC. Unfortunately, TVOC isn’t uniformly defined.
What does TVOC mean in air quality?
Total Volatile Organic Compounds
The summation of all VOCs is called the Total Volatile Organic Compounds (TVOC). The volume of gas per classification and the sum of all gases (TVOC) are important reflections of the relevant organic compounds found in indoor air.
What are safe TVOC levels?
The table below shows that less than 0.3 mg/m3 are considered low TVOC concentration levels. And levels between 0.3 mg/m3 to 0.5 mg/m3 are acceptable….Are all VOC’s harmful?
| TVOC Level mg/m3 | Level of Concern |
|---|---|
| 0.3 to 0.5 mg/m3 | Acceptable |
| 0.5 to 1 mg/m3 | Marginal |
| 1 to 3 mg/m3 | High |
What causes TVOC?
Sources of VOCs aerosol sprays. cleansers and disinfectants. moth repellents and air fresheners. stored fuels and automotive products.
Where are VOCs found?
VOCs are often components of petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning agents. VOCs are common ground-water contaminants. Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids.
Is high TVOC bad?
