Biogas – Case Study

December 2020 – Biogas Case Study

Location: Medora, Indiana

Customer: Archaea Energy

Employees: 65

Industry: Renewable Energy

Project Type: Biogas

Equipment Type: Blower and Flare Skid Package

Executive Summary: Gulf Coast Environmental Systems was tasked with finding a solution that would assist with VOC abatement and biogas processing at a landfill in Medora, Indiana.

Customer Summary: This customer, Archaea Energy, is a long-standing partner to GCES, purchasing multiple solutions to support their landfill applications which processes the landfill biogas into clean Renewable Natural Gas (RNG). Founded by landfill owners and technology developers in the energy sector, they partner with other landfills to harness the power of their biogas. They source, build, and manage projects through the entire lifecycle of the project. GCES has been supporting Archaea in this goal since 2018 with several sites already operational and many more in development across the US. Archaea chose GCES to assist in the creation of these landfill gas to energy plants because of our extensive background in waste to energy projects with nearly 500 units currently in operation.

biogas industriesProject Summary: 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. When condensed into a small space, methane is considered an explosive gas and should be handled with extreme caution. While a minimal amount of oxygen is present in this particular stream of waste gas which eliminates risk of the process concentration becoming combustible, it is important to note that the methane is still highly flammable. 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…]

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…]

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…]
