Dimethyl Sulfide

What is Dimethyl Sulfide?Dimethyl sulfide

Dimethyl sulfide (DMS), also known as methylthiomethane, is an organosulfur compound. It is a methyl sulfide, in which the sulfur atom is substituted by two methyl groups, with the chemical formula of (CH3)2S. It is a highly flammable straw-colored liquid, with a boiling point of 37 degrees Celsius, or 99 degrees Fahrenheit. This is a compound that is easily recognized by its foul odor, that is often described as “cabbage like”. Unlike many other organosulfur compounds, this disagreeable odor is present in even low concentrations of DMS. Dimethyl sulfide is the product of dimethylsulfoniopropionate (DMSP) breakdown, and is also the result of bacterial metabolism of methanethiol.

Hydrogen Sulfide – H2S

What is Hydrogen Sulfide?

Hydrogen sulfide is a chemical compound with the chemical formula H2S. This means it is made of two hydrogen atoms, and one sulfide. It is a colorless gas with an obvious identifying characteristic; it has a distinct rotten egg odor. Slightly denser than air, it can be incredibly explosive. When burning with oxygen, hydrogen sulfide burns blue, to form sulfur dioxide, and water. It is somewhat soluble in water, and acts as a weak acid. [Read more…]

My Reason, What’s Yours?

I am admittedly, and shamefully, a former climate-change denier. There. I said it! I believed that global warming was real, but thought that humans played little to no role in the process. It has happened before, and we need to stop obsessing over something we have no control over. I was not a person you would consider to be environmentally conscious, at all; in fact, those “tree-huggers” often annoyed me, with their suggestions that I make changes in my own life, to stop this process I didn’t think I had a role in.

State By State Air Permitting Resources

With so many air permitting agencies across the nation it can be a bit confusing. What permits are required in your state? In your county? In your country? This list compiles many of the major permitting agencies for each U.S. state as well as many of the federal agencies. You may also find that your state has grants that may be available for you. We have shared information on many of the common air pollution prevention and air quality grants, those for water quality and other forms of pollution control are available on many of the state websites. Many of the grants for air pollution control are specific to energy usage and the implementation of an energy efficient Regenerative Thermal Oxidizer (RTO) is often the first step to qualification.

Clean Air Act Permitting and Air Permitting Related Services often fall into the Following Categories:

  • Permit Application and Exemption Submittals to Regulatory AgenciesAir Permitting
  • Permit Condition Negotiations
  • Air Dispersion Modeling Studies
  • Compliance Audits, Assessments and Program Assistance
  • Notice-of-Violation Technical Support
  • New Source Performance Standards (NSPS)
  • National Emissions Standards for Hazardous Air Pollutants (NESHAPS)
  • Prevention of Significant Deterioration (PSD)
  • Title III – Air Toxics/Hazardous Air Pollutants (HAPs)
  • Maximum Available Control Technology (MACT) and Best Available Control Technology (BACT) studies
  • Title IV – Acid Rain (Regulation 75)
  • Title V – Operating Permit Program
