“…The systems are usually installed in a trench in a ground and are fed batch-wise or semi-continuously without any internal agitation [26,48]. There is limited horizontal mixing, which ensures that minimum retention time is reached with the hydraulic retention time (HRT) ranging between 15 to 40 days [40,41,48,58,59]. A variety of feedstocks can be used in tubular digesters, generally in the TS range of 10% to 15% [26,40,41,48,58].…”

“…The digester has a flexible floating cover where the gas is stored, which either floats directly on the slurry or in a water jacket surrounding the digestion tank [43]. The cover rises as gas production increases and its weight enables the gas to be kept under constant pressure -usually between 0.7 and 0.9 kPa [43,59]. A partition wall is included in systems that have a high height to diameter ratio to prevent short-circuiting of the fresh feed and partially digested slurry exiting the outlet [59].…”

A partition wall is included in systems that have a high height to diameter ratio to prevent short-circuiting of the fresh feed and partially digested slurry exiting the outlet [59]. The gas holding cover was commonly made of mild steel but fibreglass and reinforced plastic covers are becoming more popular [26,48,59].…”

This paper aims to provide a broad review and assessment of the feedstocks and applicable biogas technologies that are feasible in Sub-Saharan Africa (SSA). Biodigesters and feedstocks available in SSA were identified according to scale and application -household, community, institutional, and commercial. Aside from livestock manure, suitable feedstocks for household, community, and institutional biodigesters include crop residues, night soil/domestic sewage, and the organic fraction of municipal solid waste (OFMSW). Significant untapped feedstocks exist from SSA agro-processing and food production industries. Biodigesters available in SSA for household, community, and institutional installations include variations of fixed dome, plug flow, and floating cover digesters.Commercial digester designs applicable to the region include continuously stirred tank reactors and fixed film digesters. The key factors that need to be considered in selecting suitable biodigester designs for specific applications include: feedstock availability, water supply, energy demand, local materials and labour, and the level of commitment to operate and maintain the biodigester effectively.

“…Fully grown cattle can produce an average of 20 kg of manure per head per day of which 4 kg is total solids (TS) and 2.6 kg of the fresh manure is volatile solids (VS). Cattle manure has the capacity to generate 200 to 500 litres of biogas per kg of dry manure depending on the process characteristics [2].…”

The Prospects for Biogas Integration with Fuel Cells in the United Kingdom

2015

View full text Add to dashboard Cite

Anaerobic digestion (AD) presence is emerging in the UK because it has numerous environmental benefits as waste management strategy and produces valuable biogas. This work shows that up to 5.5% of UK primary energy could be met by biogas, representing 14.4% of gas consumption. Fuel cells (FCs) are the most efficient and environmentally benign energy convertor of any device of equivalent scale and in addition are well suited for biogas utilization, which has worldwide led to the emergence of numerous integrated commercial applications. Thus, biogas coupling with fuel cells is proposed as a unique and virtuous AD scheme. A technoeconomic model has been developed for the two types of AD plants with the highest development prospects in the UK, namely livestock and food waste plants, whose performance and feasibility at different scales are scrutinized under several policy scenarios, some of which incorporate supportive mechanisms for the introduction of FCs. Results confirm that conventional AD projects can already be profitable in the current market environment, while projects involving FCs proved environmentally superior, virtually suppressing harmful pollutant emissions and decreasing the CO 2 emissions from using grid electricity and natural gas, at a reasonable avoided carbon cost in the best suited cases.
