overview
Bio CNG, also known as Compressed Biogas (CBG), is a renewable energy source produced from the anaerobic digestion of organic waste materials such as agricultural residues, food waste, sewage sludge, or energy crops. It is a clean and sustainable alternative to traditional fossil fuels like natural gas.
When organic waste undergoes anaerobic digestion, bacteria break down the organic matter and produce a mixture of gases, primarily methane and carbon dioxide. This biogas can be further processed to remove impurities, moisture, and carbon dioxide, resulting in a purified methane-rich gas known as Bio CNG or CBG.
To produce 5 tons per day (TPD) of Bio CNG or CBG, a bio-refinery or biogas plant is required. The plant typically consists of the following components:
Feedstock Collection System:
Organic waste materials such as agricultural residues, food waste, or energy crops are collected and transported to the biogas plant.Pre-Treatment:
The collected feedstock undergoes pre-treatment to remove any contaminants or non-biodegradable materials. This ensures a consistent and high-quality feedstock for the anaerobic digestion process.Anaerobic Digestion:
The pre-treated feedstock is then introduced into anaerobic digesters. In these digesters, bacteria break down the organic matter in the absence of oxygen, producing biogas.Biogas Upgrading:
The raw biogas generated from anaerobic digestion contains impurities, moisture, and carbon dioxide. To convert it into Bio CNG or CBG, the biogas undergoes upgrading processes such as compression, desulphurization, and removal of moisture and carbon dioxide.Methane Enrichment:
The upgraded biogas is further processed to enrich the methane content, resulting in Bio CNG or CBG. This process involves removing excess carbon dioxide and trace impurities, resulting in a high-purity methane fuel.Compression and Storage:
The purified Bio CNG or CBG is compressed to the desired pressure and stored in high-pressure cylinders or tanks for transportation and distribution.Distribution and Utilization:
The produced Bio CNG or CBG can be used as a direct replacement for compressed natural gas (CNG) in various applications, including transportation, cooking, heating, and power generation.how it works?!
The production of 5 TPD of Bio CNG or CBG requires a consistent and reliable supply of organic waste feedstock, efficient anaerobic digestion processes, and adequate infrastructure for gas upgrading, compression, and storage. It is an environmentally friendly and sustainable solution that helps reduce greenhouse gas emissions and dependence on fossil fuels.
