Everything You Need to Know About Landfill Gas

landfill

Landfill gas is an asset as well as a serious threat. If we extract it right on time and preserve it then it will act as a valuable asset and if we leave as it is then it will be a serious threat as it can explode at any time. Landfill gas is produced under […]

Biogas Cleanup Methods

Cleanup of biogas is primarily achieved by carbon dioxide removal which enhances the energy value of the gas to give longer, driving distances with a fixed gas storage volume. Removal of carbon dioxide also provides a consistent gas quality with respect to energy value. The latter is regarded to be of great importance from the vehicle […]

An Introduction to Greenhouse Gases

Greenhouse-Gas-Emissions

Greenhouse gases are generally any gas molecules or compounds in the atmosphere which interact with outgoing infrared radiation from the sun and thus contribute to the Greenhouse Effect by warming the atmosphere. The major constituents of the atmosphere such as nitrogen (N2) and oxygen (O2) do not interact with infrared radiation and, thus are not […]

Protecting Rainforests

Rising levels of carbon dioxide (CO2) in the atmosphere have been linked to climate change. Rainforests are part of the solution to climate change because they remove 4.4 billion tonnes of CO2 from the atmosphere every year. With the destruction of large sections of the rainforest to make way for cattle ranching, agriculture, logging or […]

Why Ocean Acidification Matters

There is a forlorn hope that spraying 7 billion tonnes per year of fossil carbon (in the form of carbon dioxide) from the combustion of coal, oil and gas into the atmosphere will have little impact on the chemical structure of the atmosphere and the oceans. Sadly, this is not the case. Since the industrial […]

Biogas Enrichment using PSA Technique

AD-plant

Pressure swing adsorption, also known as carbon molecular sieves, is one of most popular biogas upgrading techniques. A typical PSA system is composed of four vessels in series that are filled with adsorbent media which is capable of removing water vapor, CO2, N2 and O2 from the biogas stream. During operation, each adsorber operates in an alternating […]
