Factors Influencing the Selection of Biogas Plant Size
In this article, the first part provides an overview of biogas plant size selection before dwelling on factors influencing the selection of the biogas plant size. These factors include feedstock supply, capital availability, environmental analysis and consciousness, and local government policy, among others.
Factors Influencing the Selection of Biogas Plant Construction Site
When carrying out biogas construction and implementation, there are key areas that need to be considered before setting up the project. One of them is where the site will be set up for biogas plant construction. This article highlights the factors influencing the selection of the biogas plant site. The site selection for biogas production should be convenient for both biogas production and for consumers.
An Overview of Biogas Plant Construction
Construction of any part or structure is the joining of many sub-parts into one main structure. In a biogas plant, construction is the most critical part of the making of a project because it entails the actualization of the idea to be a tangible project. Biogas plant construction is comprised of many activities, all interlinked into one major activity. This section covers the following areas: Biogas construction considerations, biogas plant construction materials, and biogas key construction parameters.
Excavation and Layout of a Fixed-Dome Biogas System
This article aims at providing a clear and step-by-step guideline on the excavation process and foundation for a biogas plant. Pointing out the possible options that would be best in the construction. This article goes over the following steps: excavation and methods to be used in pit digging, identification of a central point, base construction, laying of the bricks, designing of hooks, inlet, and outlet piping as well as plastering, supporting, and curing the wall.
Construction of Fixed-Dome Digester, Mixing and Expansion Biogas Chambers
This article aims to take a look at the process of constructing a dome and expansion chamber. The step by step guideline has been instrumental in the construction of a reliable and production efficient plant. The guide takes the following approach, starting with dome construction which involves fixing of a gas pipe, building of the dome, closing of the dome and plastering the dome. Lastly, the article offers a guide on how to make a good and long lasting expansion chamber
