Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestion
The reason for carryover of silica and phosphate in the high pressure steam were rightly identified and the ammonia plant resumed normal operation after replacing rotor of high pressure PAC steam turbine. The ammonia plant continued with high load operation at 110% afterwards without noticing any process related abnormality for one further year.
