“…The pyrolysis step was carried out using continuous apparatus (horizontally placed pyrolysis chamber equipped with a slowly rotating helix) for biochar production (Maroušek 2014) which utilizes waste flue gases from the biogas cogeneration unit for the pyrolysis (410°C, hydraulic retention time of 10 min). For the PE, the solid pyrolysis residue was pelleted using a Falach 50 briquette press with a custom-made adapter (FALACH s.r.o., Czech Republic) operating at 50 kg h -1 as described in Maroušek et al (2015b). This step was followed by an analysis of the European norms (European Committee for Standardization, as stated in Mardoyan and Braun 2015).…”

There are thousands of pulp and paper mills worldwide. The utilization of the waste they produce is a problem of particular importance. Many methods have already been put forward for the management of the mixture of lime mud and cellulose fibre residues. The chemical nature of its management presents a challenge because it requires costly catalysts and long retention times or raises criticisms about its environmental impacts. Several technoeconomic analyses (including various modifications to anaerobic fermentation; combustion; pyrolysis and composting) have been carried out on an almost commercial scale to holistically assess the wide portfolio of management issues. The data obtained indicate that it cannot be clearly concluded that one particular method is the best for dealing with all management issues. However, the conclusions do provide an insight into how processing technologies can be adapted in specific cases.

“…Implementation of the greenhouse gas emission policies would cause increases in the price of energy due to high costs of carbon capture and storage (CCS) technologies. To reduce the negative impact of CCS on energy prices, new technologies that reduce the energy demand of the process have been extensively researched (Bandyopadhyay 2010; Damartzis et al 2014) or alternative methods of CO 2 emissions reduction have been analyzed (Maroušek et al 2014). This paper addresses the presentation of a mobile amine carbon capture pilot plant.…”

As a part of the strategic research program ''Advanced technologies for energy generation: Development of a technology for highly efficient zero-emission coal-fired power units integrated with CO 2 capture'', a mobile CO 2 absorption pilot plant was erected. The main purpose of the pilot plant was to demonstrate the postcombustion technology in conjunction with a coal-fired power plant. The pilot plant captured CO 2 by chemical absorption in amine-based solvents, which was considered to be the best adapted technology to the requirements of coal-fired power plants and suitable for retrofitting to existing units. The pilot plant captured up to 1000 kg/day of CO 2 from the power plant's flue gases with CO 2 recovery exceeding 90 %. The flexible process flowsheet of the pilot plant offered high potential for the validation of various improvements, which were designed to reduce the process energy demand and to increase the CO 2 recovery. This paper summarizes the initial operation experience at the TAURON Łaziska Power Plant in Poland. Selected first results obtained are presented and discussed. The initial campaigns utilized 20 and 30 wt% monoethanolamine (MEA) solutions recognized as baseline solvents that were suitable for comparative purposes. The initial campaigns at the pilot plant successfully demonstrated reliable operation and promising results.

“…The two main procedures for converting biomass into bioenergy/electricity are fermentation and anaerobic digestion. The fermentation residue processing is shown in [13] and [14] to yield a biochar that technologically and economically outperforms many of the conventional solid biofuels. Biotechnological partition enables minimization of the anaerobic fermenter dimensions and reduction of the retention time by enhancing and accelerating biogas production [10,11].…”

Summary Depleting fossil fuels and the pollution resulting from their consumption indicate an urgent need for clean and dependable alternatives such as renewable energies. Biomass is a free and abundant source of renewable energy. Municipal solid waste (MSW) as one of the main categories of biomass has always been an issue for metropolitan cities. It has, however, a high potential for biogas production. In this study, the technical and economic aspects of generating electrical power through solid oxide fuel cells (SOFCs) powered by injecting biogas derived from Tehran's MSW, as a case study, are investigated. The main objectives of the current study are to identify the power generation capability of the process and find out if it can result in a competitive energy resource. The total amount of obtainable methane through anaerobic digestion of MSW and then the achievable power generation capacity by using the obtained biogas are computed using the electrochemical relations inside the SOFC. The economic calculations are carried out to estimate the final price of the generated electricity, taking into account the major capital and ongoing costs of the required equipment. The effect of variations of MSW composition on the power generation capability and final electricity price is also studied. Moreover, the application of a gas turbine (GT) with the SOFC as a hybrid SOFC–GT system to recover the produced heat by SOFC and its effect on the power generation capability and the final electricity price are investigated. Results indicate that around 997.3 tons day−1 biomethane can be generated using Tehran's MSW. By using the SOFC, the produced biogas can generate 300 MWAC electrical power with a final cost of $0.178 kWh−1. By using the hybrid SOFC–GT, the electrical power capacity is increased to 525 MWAC, and the final electricity cost drops to $0.11 kWh−1, which indicates its competitiveness with other common energy resources in the near future, especially by considering different governmental subsidy policies that support renewable energy resources. The considerable environmental benefits of the proposed procedure, from both MSW management and CO2 emission reduction points of view, make it a promising sustainable energy resource for the future.
