Landfill RNG Case Study

CASE STUDY
THERMAL OXIDIZER
LANDFILL – BIOGAS | NOVEMBER 2018

Industry: Landfill/Waste Management
Project Type: Biogas
Project Goal: Building a biogas facility to develop pipeline quality natural gas
Equipment Type: Carbon Adsorber and Thermal Oxidizer

EXECUTIVE SUMMARY:
Gulf Coast Environmental Systems was tasked with finding a pollution control solution that could handle two combined PSA reject gas vent streams.

PROJECT OVERVIEW:
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…]

25 Days to a Greener Holiday Season

The holiday season is a time of joy, family, and giving. It is also a time of great waste, spending, and polluting. We here are GCES wanted to put together some tips to help make this holiday season just a little bit greener.

 

Greener Holiday Season
Handmade and DIY gifts are not only more thoughtful, but they help reduce emissions, significantly. Manufacturing, packaging, transport… all of these steps release dangerous compounds into the atmosphere, that are directly tied to climate change.

Is There Money Hiding in Your Landfill?

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. Methane from Landfills

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…]

Earth Day Tips

With Earth Day being in the month of April, we here at GCES spent a lot of timelearning ways we can reduce our own carbon foot prints. We shared what we learned, including great articles, tips, and videos so our followers could learn with us. With all that research, we were able to put together a pretty awesome series of tips, we titled “Easy Ways to Save The Planet.” These daily posts were designed to help people reduce the amount of energy they use, waste they create, and save money! While we have the industrial side of it covered, here, these are things you can easily emulate. It doesn’t get any better than that!

 

With this being Day 1 of our, series we decided to keep it simple with #Recycle. Looking for ways to improve on the basics of cardboard, glass and paper? Well look no further, those little K-cups of coffee can be recycled! It is estimated that 17 million K-cups end up in US landfills every year. Keep watching for more easy ways to save the planet from your pollution control partners at GCES.  [Read more…]
