“…A purification unit mounted in series and ordered this time so that the raw biogas passes through filters (3) of wood shavings, steel wool and activated carbon has made it possible to obtain a gas with a proportion of H2S approaching 0 (Orhorhoro et al, 2018). This result is the same as that obtained for the experiments carried out in this section.…”

Biogas upgrading in Africa remains a huge challenge for producers of small installations due to the high cost of acquisition of all-in-one installations designed and used in developed countries. This study brings a clear idea on some purification methods accessible to these small producers while proposing those optimal for decarbonation and desulphurization of biogas. Starting from the analysis over time of the biogas resulting from the anaerobic digestion of cow dung, the system of NaOH filters and steel wool mounted in series is the one proposed for optimality (with purification capacities respective CO2 of the order of 95.9063 Ã‚Â± 0.0864 % and H2S of 100 %). Better still, the use of a steel wool filter in series with activated carbon (based on coconut shells or bamboo) makes it possible to increase the desulfurization capacity of the latter up to 100 %.

“…Concerning the purification of H2S with activated carbon made from coconut shells, (Zulkefli et al, 2019) obtained an adsorption capacity of 0.582 mg H2S/g. (Orhorhoro et al, 2018) obtained a purification capacity of at least 98%. This validates the purifying capacity found in our study.…”

“…Biochemical Technology: Biochemical technology involves the breakdown of hemicellulose fraction. The two biochemical process options are anaerobic digestion (AD) and aerobic fermentation (Orhorhoro et al, 2016a;Orhorhoro et al, 2018a). In AD process, high moisture content (85-90%) biomass is converted into biogas by microorganisms in the absence of oxygen (Orhorhoro et al, 2017b;Orhorhoro et al, 2017bc).…”

“…The raw biogas is purified before it can be used, and this is because of the presence of impurities such as hydrogen sulphide, dust, water, siloxane and halogenates hydrocarbons. These impurities if not removed can cause health problems, corrosion problems in processing, handling and storage facilities/equipment (Orhorhoro et al, 2018a).…”

Nigeria just likes every other country in sub-Sahara Africa is faced with solid waste generation and management. Solid waste is dump indiscriminately and seen in huge heaps on any piece of unused land, around buildings, drainage system, institutions, playing ground, roads side, and in the open market places in major cities and towns. Living with solid wastes littered around seems to be an acceptable way of life among the people in this part of the world. This research work reported intensive review on solid wastes generation and management in this region using Nigeria as a case study. The application of knowledge of solid waste generation and management approach is crucial for inculcating a change of attitude towards improving the management of generated solid waste in this region. From the review, it was observed that biodegradable solid waste that can be managed via the biogas technology and landfill technology have the highest percentage fraction while the remaining fraction that comprised of non-biodegradable and combustible solid waste can be managed via other technology such incineration, gasification, pyrolysis, etc. Besides, the inefficient management of generated solid waste by individuals, households, institution, consumers and waste management companies can be attributed to inadequate information on waste management benefits, insufficient academic research and industry linkages, financial constraint, economic constraint, cultural constraint, lack of planning and projection, social constraint, lack of producers' involvement in waste management as well as poor implementation of government policies and lack of comprehensive legal framework.

Although CO2 has zero heating value for combustion in air/oxygen, biogas is still a high-quality fuel gas due to methane content which can be as high as 70% in biogas produced from municipal solid wastes, making biogas a potential energy source for household consumption (Tester et al, 2005;Olmedo et al, 2014).…”

The rate of MSW generation is increasing and at present, there is no single engineered landfill designed to address the challenges posed by MSW generation in Nigeria. Unmanaged open dump sites and uncontrolled MSW disposal is currently practiced in Nigeria, thus this research work which is focused on the effects of landfill gas flow trajectories at three distinct temperature phases on the stress-strain-displacement properties of a gas extraction. Conservation mass equation was derived for solid, liquid, and gaseous phase. A PVC plastic with a linear elastic isotropic property was used. Von Mises Stress was used as the default failure criterion. The material yield and tensile strength were 52 N/mm^2 and 30 N/mm^2. Other properties of the material include; elastic modulus of 3000 N/mm^2, poisson's ratio of 0.394, mass density of 1020 g/cm^3, shear modulus of 318.9 N/mm^2, and thermal expansion coefficient of 79/K. The results obtained reveal that the rate of gas generation in a landfill is dependent on the increase in temperature and pressure within the landfill system, usually causing subsurface pressures in the landfill to be higher than either the atmospheric pressure or indoor air pressure.
