You cannot turn on a computer or television, without seeing a story about climate change. Our planet is being choked by man-made emissions, and experts spend countless hours and dollars researching ways to reduce this plague, that we continue to bring upon ourselves. Changes have already been made in many industries, with hybrid vehicles, solar powered homes, and products made of recycled goods becoming ever more popular. But there are still huge questions when it comes to manufacturing and industrial fields. Nuclear power plants, steel companies, waste management facilities, coal mines… all industries that have come under fire in recent years, for producing dangerous emissions. The majority of recommendations to reduce these emissions involve cutting back on production, which could potentially have massive economic repercussions. But here is the thing, there is a simple solution, that has existed for decades. [Read more…]
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…]
What is Methyl Mercaptan?
Methyl Mercaptan, also known as Methanethiol, is a volatile organic compound known as an organosulfur, because it contains sulfur. Methyl mercaptan is a member of a series of compounds, in which there can be chains of up to 20 carbon-atoms attached to sulfur. The chemical formula for methanethiol is CH3SH; it is classified as a thiol. It is colorless, highly flammable, and has a strong rotten-cabbage-like odor. It is a colorless, low-boiling liquid, that is denser than water. When inhaled, Methyl Mercaptan is very toxic, and the dangerous gas is often overlooked when in low concentrations. It can undergo steam reforming to hydrogen-rich gas over cerium oxide-coated rhodium or aluminum oxide catalyst via the solid-gas reaction, under certain operating conditions. This process has potential use in toxic-waste treatment, such as removal of methanethiol present in industrial-waste off-gas. Because it is derived from decaying organic matter, Methyl Mercaptan is a weak acid, and is reactive with dissolved metals, in aqueous solutions. [Read more…]
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.

At GCES so much of our job focus is on VOCs. Over the years we have come to realize that VOCs and the treatment of them is very misunderstood. Our Technical Director, Chad Clark, has spent much of his career as a Mechanical Engineer dedicated to the advancement of VOC abatement. Having developed cutting edge technology and BACT improvements he is a true subject matter expert and has provided the following to help improve the understanding of VOCs and how to best abate them through the use of pollution control equipment.
