| dc.description.abstract | Upgrading and compressing of natural gas provides a safer and cheaper alternative energy source for transportation, electrical production and also increases its storage capabilities. The global use of natural gas is growing quickly. This is primary attributed to its favorable characteristics and to the environmental advantages it enjoys over other fossil fuels such as petroleum, oil and coal.one of the key challenges in supplying natural gas is the form (phase) at which it should be delivered. Natural gas like biogas maybe supplied to the consumer by upgrading to reduce contaminates and finally as a compressed gas or through pipe lines. when there is a considerable distance involved in transporting natural gas. The present study focuses on development of a gas cleaning and compressing step for a product gas produced in a biogas plant. Removal of contaminants from biogas can therefore significantly improve the gas quality. The study shows that the Theoretical potential of waste and residues for biogas production is around 230kg/day of caferia food wasted which is produced about 9.987m 3 /day biogas and 3.74 kwh/day using the energy conversion method from a biogas plant. This work addresses the simulation and experimental investigation of biogas Upgrading and compression from biomethane production of 10m 3 biogas plant of food waste. The purification study was investigated using combined chemical methods of (activated carbon, NaOH, KOH, Wood charcoal and silica gel) improving the calorific value of biogas. Experiment results revealed that the chemical solution used effectively in reacting with CO , H 2 S, H 2 O in biogas (over 80–96%) removal efficiency, creating CH enriched biogas. The experimental result shows these innovative technologies reduce the acidic content H 4 S by 96 % and removes the CO by 80-90 %. Thus, the Methane content has been increased from 56.7 % to 87 %. The CO 2 content reduces from 36 % to 10 %. First the process flow sheet is constructed based on the common process configuration. Then the key parameters taken from 2 literature are simulated using MATLAB 2017 to determine amount of chemical needed for each g of gas produced in streams of the plant. | en_US |
