Bio-CNG Production in India - Challenges in Technology Vendor Identification

Bio-CNG Production in India - Technology Vendor Identification

1. Project Description

This project aims to identify?novel technologies for the conversion of agro-residue and waste into?Renewable Natural Gas (RNG) plant and Bio-CNG?and evaluate technology vendors utilizing a modular, plug-and-play digester model.?The biogas is further purified to meet the standard IS 16087:2016, and compressed and stored under high pressure in cylinder cascades for use in transportation and industrial applications.

The plant will prioritize:

• Feedstock Flexibility: Ability to handle a variety of organic materials (starch and cellulosic) from agricultural, and farm waste products like Napier Grass, Bagasse, Rice Straw, Maize Straw, Wheat Straw, and Soybean Thrash for optimal yield.?
• Minimal Pre-treatment: Technologies that eliminate complex pre-treatment steps like enzymatic hydrolysis.
• Cost-Effectiveness: Focus on balancing capital and operational costs for a viable RNG production facility.
• Continuous Stirred Tank Reactor (CSTR) technology is used in biogas plants to process manure and dung. CSTRs are closed tanks that contain a continuously agitated and mixed content. The CSTR process involves charging organic substrates into primary digesters through a buffer tank or solid feeder, then feeding the primary digester with fresh substrates. The mixing inside the primary digester is optimized, and microorganisms are introduced and maintained at optimal conditions. This allows for efficient biogas production. The biogas can then be used to produce electric and thermal energy, or purified to separate CO2 from bio-methane for chemical and alimentary industries
• The purity specifications for biogas (biomethane) as per IS 16087:2016 (Reaffirmed Year: 2020) outline the quality standards that biogas must meet to ensure its suitability for various applications. Below are the key purity specifications typically included in this standard: Methane Content: The methane content in biogas should typically be within a specified range to ensure its energy value and suitability for use as a renewable fuel. This range may vary depending on the intended application of the biogas.Impurities Content: The standard may specify maximum allowable levels of various impurities such as carbon dioxide (CO2), hydrogen sulfide (H2S), moisture content, and other trace contaminants. These impurities can affect the performance of biogas equipment and may need to be minimized to meet quality requirements.Odorization: Depending on the application, biogas may need to be odorized to provide a warning smell in case of leaks. The standard may specify requirements for the addition of odorants and the intensity of odorization.Pressure and Temperature: Specifications may include requirements for the pressure and temperature of the biogas at the point of delivery to ensure consistency and compatibility with downstream equipment and distribution systems.Particle Content: The standard may also address the presence of particulate matter or solid contaminants in the biogas, which can cause fouling or damage to equipment and may need to be filtered or removed.Safety Requirements: In addition to purity specifications, safety requirements such as explosion limits, flammability, and toxicity may also be addressed to ensure the safe handling and use of biogas.
• These purity specifications are designed to ensure the quality, safety, and performance of biogas for its intended applications, including power generation, heating, transportation, and industrial processes. Compliance with these standards is essential for the widespread adoption and acceptance of biogas as a renewable energy source.
