Quantitative Risk Assessment of Biogas Plant – Determination of Assumptions and Estimation of Selected Top Event

Periodica Polytechnica Chemical Engineering

Biogas plants are a specific facility from the QRA (Quantitative Risk Assessment) methodologies' point of view, especially in the case of the determination of the event frequency of accident scenarios for biogas leakage from a gas holder and subsequent initiation. QRA methodologies determine event frequencies for different types of accident events related to vessels made of steel. Gas holders installed at biogas plants are predominantly made of other materials and are often integrated with the fermenter. It is therefore a specific type of gas holder, differing from that which is commonly used in the chemical industry. In addition, long-term experience is not available for the operation of biogas plants, unlike in the chemical industry. The event frequencies listed in the QRA methodologies are not relevant for the risk assessment of biogas plants. This work is focused on setting the prerequisites for QRA of biogas storage, including for example: information on hazardous chemical ...

Assessment of biogas potential hazards

Renewable Energy, 2011

Biogas produced from anaerobic fermentation of organic substances represents an alternative renewable energy source. Its utilization would contribute to substantial reduction of the solid waste volume in land-filling and incineration. Biogas so produced could be utilized on site or it could be injected into the natural gas distribution network. Microbiological and chemical compositions of different biogas types were determined in order to conduct qualitative and quantitative risk assessments of the potential health hazards associated with biogas use for cooking. Biogas types that could be allowed for injection in the natural gas pipelines were listed with recommendations, while outlining the European biogas injection policy. Results indicated that the injection of the processed biogas in the distribution network did not present any additional chemical or microbiological risk to consumers when compared to natural gas, provided that the biogas resulted from the fermentation of non-dangerous waste. However, since this study did not examine the microbiological and chemical composition of biogas originating from wastewater sludges and/or industrial wastes, the injection of this type of biogas into the gas distribution network should not be allowed unless a similar risk evaluation study is conducted for each case.

Impact assessment of biogas projects in latvia

International Journal of Sustainable Development and Planning, 2014

During the last 5 years, more than 30 cogeneration plants where biogas is burned have been built in Latvia. The biogas plants help Latvia to comply with the European Parliament and Council Directive 2009/28/EC [1] on the promotion of renewable energy initiated on 23 April 2009. The directive states that the share of renewable energy must reach 40% of the total fi nal energy consumption by 2020. By using biogas produced in biogas plants, the share of renewable energy in Latvia has increased. At the same time, the production of biogas is new for this country; therefore, there has been a lack of a systematic approach in the planning procedure of biogas plants. An environmental evaluation of biogas plants during the planning process is essential. According to Latvian legislation, an Environmental Impact Assessment screening has to be performed during the biogas plants planning step. Within the research, quantitative and qualitative criteria for biogas projects evaluation are developed.

Potential hazards posed by biogas plants

Renewable and Sustainable Energy Reviews, 2021

One effective method of clean energy generation is to use biogas. The biogas production technologies are now highly developed, especially at the level of local biogas plants. Unfortunately, it has been impossible to avoid inservice fatal accidents. Therefore, the design and construction of new technological installations intended for biogas large-scale production have to take account of the plant safe operation. In the first place, this applies to the course of industrial processes and to potential failures that may occur in them due to the flammability and toxicity of biogas constituents. This paper is focused on the hazards that biogas poses to human health and life. It presents the hazard zones arising due to possible scenarios following a release of biogas from a biogas plant. Probit functions and numerical modelling of the spread of thermal radiation due to a fire and of the toxic cloud arising therefrom are used to calculate the probability of serious injury to health and a loss of life depending on the distance from the gas release site. It is estimated that for a high-pressure tank containing 3000 m 3 of biogas under the pressure of 10 MPa the life-threatening zone due to a potential fire of released gas has the range of about 30 m. There is about 10 m hazard zone related to the gas explosion, and the zone with the risk of poisoning due to the gas cloud toxic concentration has the range of about 20 m from the failure site.

Environmental Assessment of the Life Cycle of Electricity Generation from Biogas in Polish Conditions

Energies

Life cycle analysis allows for the assessment of the qualitative and quantitative relationship between selected areas of human activity and the consequences for the environment. One of the important areas is the production of electricity and heat, for which the main raw material in Poland is hard coal. An alternative may be to use biogas as a fuel for energy purposes. This article presents the assessment of environmental hazards caused by the production of energy from biogas. The analysis took into account the change of the substrate from maize silage, commonly used in Polish biogas plants, to waste from the domestic agri-food industry. The evaluation covered the acquisition of substrates, their transport to a biogas plant, generation of electricity from biogas, and management of the generated by-products. The analysis was done in terms of both the impact and sensitivity categories. It was found that the emission of pollutants related to the acquisition of the substrate plays a key ...

SAFETY PRECAUTIONS AND REGULATION ON INDUSTRIAL BIOGAS PLANT: TURKISH MARKET

International Journal of Ecosystems and Ecology Sciences (IJEES), 2016

Biogas, as one of the renewable energy sources, has become increasingly an important alternative energy source. Plants, which treat waste to produce energy, have moved to industrialized size with intensive studies in recent years. Efficiency and safe operation of these plants are very important for plants sustainability. For this purpose, safety measures must be standardized and applied to whole process from manufacturing to energy production within a biogas plant. In this study, all potential risks and necessary precautions taken against these identified risks are listed in a continuously running biogas plant. Moreover, it is also emphasized the necessity of drafting a regulation and the content of this regulation on this issue within Turkey.

Analysing the Impact on Health and Environment from Biogas Production Process and Biomass Combustion: A Scoping Review

International Journal of Environmental Research and Public Health

The increasing demand for renewable energy production entails the development of novel green technologies, among them the use of biomass for energy generation. Industrial processes raise new issues regarding emerging risks for the health of people working in biogas plants and of nearby communities. The potential epidemiological and environmental impacts on human health related to biogas plants were assessed by means of a review of the available literature. Nineteen papers published between 2000 and 2022 were identified through electronic database search using search strings. The selected works are epidemiological studies and environmental monitoring studies, which aimed at investigating what are the health risk factors for biogas plant workers and for people living in the surrounding communities. The results of the epidemiological studies revealed a potential exposure to endotoxins and fungi that are associated with respiratory symptoms. Furthermore, the results from the environment...

Development of an EIA screening phase for biogas projects in Latvia

Environmental Impact, 2012

One of the main priorities among European Union member states is to promote renewable energy. Latvia also has to comply with the European Parliament and Council Directive 2009/28/EC on the promotion of renewable energy initiated on 23 April 2009. The directive states that the share of renewable energy has to reach 40 % of total final energy consumption by 2020. Part of this share can be achieved with the energy produced by burning biogas in cogeneration plants. Each domestic activity generates an environmental impact. Before the activity commences, the potential impact of activities has to be assessed. One of the tools that is widely used and is included in the Latvian legislation is the Environmental Impact Assessment (EIA). Environmental impact assessments are applied to different objects, where there is a risk that the construction or operation may have a negative impact on the environment, as well as on human health. According to Latvian legislation, the activities, depending on their potential impact, are divided into two parts: the activities for which an EIA has to be completed and activities for which a screening has to be performed. The aim of the screening is to evaluate whether the activities can cause significant effects on the environment. Solely on the basis of the results of the screening a decision is made whether to perform the EIA procedure or not. The definition of the significance of the impact is essential. The defined criteria in the European Union legislation are included in the legislation of Latvia. The criteria specify the minimum range of points to be covered during the screening. Biogas production through anaerobic digestion is considered as one of the most successful methods of dealing with increasing environmental pollution. Heat and electricity are produced by burning biogas in cogeneration plants. A wide variety of inputs can be used to produce biogas: livestock manure, crop
