740 views

LPG has a higher calorific value compared to biogas. While biogas typically contains 55-65% methane and has a calorific value around 21 MJ/kg, LPG, consisting mainly of propane and butane, boasts a calorific value of approximately 46 MJ/kg. This makes LPG a more energy-efficient fuel option.

FAQs & Answers

  1. What is the calorific value of LPG? LPG has a calorific value of approximately 46 MJ/kg, making it a high-energy fuel commonly used for heating and cooking.
  2. Why does LPG have a higher calorific value than biogas? LPG contains propane and butane which have higher energy content per kilogram compared to the methane-rich composition of biogas, resulting in a higher calorific value.
  3. Can biogas be used as an alternative to LPG? Yes, biogas can be used as a renewable alternative to LPG, but it has a lower calorific value and may require different handling and storage conditions.
