Gulf Coast Environmental Systems designs, engineers, manufactures, and offers service to a wide range of pollution control solutions, treating countless different compounds and Volatile Organic Compounds (VOCs). We have put together a collection of detailed articles that explain the most common VOCs we face in our industry, and outline some of the ways we abate them. GCES is constantly adding to this list, so be sure to check back, often.
Industrial air pollution gets a lot of slack in the media, because it has been directly linked to climate change. Regulatory agencies on nearly every continent have taken further steps to reduce the amount of emissions allowed by industrial processes, and the only method of reducing the pollutants in exhaust emissions is with industrial air pollution control equipment.
In many manufacturing processes, volatile organic compounds (VOCs) are produced as a byproduct of production or processing. Industrial air pollution control equipment is used to process or abate those dangerous chemicals and compounds, so they do not end up in the air, soil, and/or water. This encompasses just about every manufacturing process you can think of; food, beverage, packaging, steel, natural gas, oil, cosmetics, automotive, paint, pharmacy, printing, et cetera. The price to install this equipment varies greatly, from tens of thousands of dollars, to millions of dollars, depending on the size of the process streams, and what types of VOCs and hazardous air pollutants the streams contain. This equipment is mandatory in most cases, and is the responsibility of the facility to purchase.
Because of the associated cost, pollution control equipment is often something facilities are not excited to purchase. But what if pollution control equipment was on the profit side of your budget sheet, instead of the expense side? There are a few ways pollution control equipment can help pay for itself, and sometimes even produce a profit for the facility.
- Methane Abatement
- Heat Recovery
- Solvent Recovery
- Carbon Trading
- Tax Incentives
- VOC & NOx Trade
- RNG + Green Energy
LANDFILL – BIOGAS | NOVEMBER 2018
Gulf Coast Environmental Systems was tasked with finding a pollution control solution that could handle two combined PSA reject gas vent streams.
In this case, Pressure Swing Adsorption (PSA) systems are cleaning biogas from a landfill. Potentially dangerous gases like methane (CH4), carbon dioxide (CO2), sulfides, and ammonia, are created by the decomposition and evaporation of organic compounds as well as chemical reactions between waste components. These gases and other hydrocarbons are often considered greenhouse gases and play a huge role in global warming. According to the EPA, in the United States landfills are the third most prevalent source of methane and other greenhouse gases. Another risk when dealing with methane is the flammability of the gas which is incredibly high. When condensed into a small space, methane is considered an explosive, and should be handled with extreme caution. The fact that a minimal amount of oxygen is present in this particular stream of waste gas eliminates risk of the process concentration becoming combustible that could lead to flashback. However, poorly designed or maintained landfills run the risk of higher levels of oxygen entrainment leading to elevated danger and uncontrolled greenhouse gas emissions. [Read more…]
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 gases are released by landfills?
Landfills consist of a complex mix of gases and VOCs, and are a source of major pollution, and potential revenue… which we will address later in this article. Dangerous gases like methane (CH4), carbon dioxide(CO2), sulfides (SOx), and ammonia, are created by the decomposition and evaporation of organic compounds, as well as chemical reactions between waste components. Methane and carbon dioxide are the most prevalent, making up between 90 and 98% of all gases and VOCs released.
Why are these chemicals a concern?
These gases and VOCs are considered greenhouse gases, and play a huge role in global warming. According to the EPA, in the United States, landfills are the third most prevalent source of methane, and other greenhouse gases. Another risk when dealing with methane is the flammability of the gas, which is incredibly high. When condensed into a small space, methane is considered an explosive, and should be handled with extreme caution. Landfill gas explosions are not uncommon.
In addition to pollution and the risk of exploding, these VOCs pose a serious risk to human health. They have been linked to eye, throat and lung irritation, nausea, headache, nasal blockage, sleeping difficulties, weight loss, chest pain, and even asthma. Some recent studies indicate a connection between air pollution, and Alzheimer’s, diabetes, and slow fetal development. [Read more…]
