3 mins readApr 02, 2019Sulfur dioxide (SO2) EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x).

Sep 11, 2018The Halemaumau plume in Kilauea Crater at Hawaii Volcanoes NP contains extremely high levels of sulfur dioxide, about 500-1,000 tones/day. The NPS sulfur dioxide advisory program alerts the public and park staff if air quality conditions reach unhealthy levels.

May 08, 2018“Interpreting the satellite SO 2 data for events like this is complicated because there are multiple SO 2 sources that combine to form the volcanic sulfur dioxide plume. Kilauea volcano has several sources of sulfur dioxide degassing: the summit caldera (a significant source since 2008); the Pu’u ‘O’o vent on the East Rift Zone; and now the new eruption site in Leilani Estates,” said

This report summarizes the annual progress of EPA’s Clean Air Markets Programs such as the Acid Rain Program (ARP) and the Cross-State Air Pollution Rule (CSAPR). EPA systematically collects data on emissions, compliance, and environmental effects, these data are highlighted in our Progress Reports.

Jan 21, 2021Ozone (O3) Air Quality Standards The Clean Air Act requires EPA to set national ambient air quality standards (NAAQS) for ozone and five other pollutants considered harmful to public health and the environment (the other pollutants are particulate matter, nitrogen oxides, carbon monoxide, sulfur dioxide and lead).

Carbon dioxide is a natural gas found in our atmosphere. It is colorless, odorless, and tasteless - indistinguishable by individuals. By volume, dry air contains approximately 78% nitrogen, 21% oxygen, 1% argon, but only 0.04% carbon dioxide and small amounts of other gases.. At 0.04% CO2 (400 parts per million) under normal conditions, you will never have to worry about Carbon Dioxide.

QUALITY INDEX SYSTEM Dividing the Interfacial Tension(IFT) by the Neutralisation Number(NN) provides a numerical value that is an excellent means of evaluating oil condition. This value is known as the Oil Quality Index(OQIN) or Myers Index Number(MIN). A new oil , for example has a OQIN of 1500. OQIN = IFT 1500=45.0(typical new oil)

Also consider testing the water in your process as well. Brewers and vintners are keenly aware that water purity is just as important to end quality as the gas that they are using in your process. In fact, hydrocarbons like benzene are more likely to appear in the water in

Feb 22, 2017How to tell if there is a gas leak. Many homes use natural gas for heat, hot water, and home appliances. Natural gas has no smell, which means a small leak would be impossible to detect.

SO2 in the air sample is absorbed in 0.03 normal hydrogen peroxide (H2O2) reagent (ad- justed to about pH 5).1011 The stable and nonvolatile sulfuric acid formed in this process is titrated with standard alkali. The method requires only simple equipment and can be performed by analysts having lesser skills; it is pre- ferable to the West-Gaeke

Developed, engineered and manufactured in the United States, the AerosphereTM CO2 Monitoring System provides easy to use plug-and-play capabilities to install near any potential carbon dioxide leak. This effective and versatile solution provides easy detection and notification of a carbon dioxide leak in any restaurant, convenience store, grow

Drilling, fracking, and associated infrastructure cause significant and dangerous air pollution. Throughout the well pad construction, drilling, fracking, and production, many chemicals leak and are released into the air and travel into the homes, playgrounds, schools, medical facilities, and communities of nearby residents. For many years since fracking began in Pennsylvania, residents have

Leakage of such high temperature steam posed a significant safety risk for all those on site and the leakage was also negatively influencing the quality of the process. In addition, the steam leakage was causing extremely high maintenance costs due to down time.

Nitrogen Oxides (mainly NO and NO 2), or NO x, is the generic term for a group of highly reactive gases, which contain nitrogen and oxygen in various amounts and chemical configurations.Most of the nitrogen oxides are colorless and odorless. However, one very common pollutant, nitrogen dioxide (NO 2) along with other particles in the air can often be seen as a reddish-brown layer of smog over
