Biogaz+ control and optimization software for biogas plant operations
Opis oferty
The subject matter of this Invitation is Biogaz+ software designed to control and optimize biogas plant operations. Based on many years of experience in research on methane fermentation processes, the Ecotechnologies Laboratory of the Poznań University of Life Sciences provides technological supervision services for biogas plants. The supervision consists in controlling and interpreting process parameters. In order to deliver special value, the supervision should be enhanced with a series of chemical analyses of the fermenting pulp. Some of these studies can be performed onsite by biogas plant operators while others require sophisticated equipment available at universities and other institutions. Also, when controlling specific parameters of substrates used in biogas plants (biogas efficiency rates and prices), some measures can be taken to optimize the functioning of the biogas plant to make it more profitable.
Considering the above, the author developed a program which combines all of these analyses into a singe coherent system. It runs online in a Web browser at www.biogazplus.pl. The program uses the installation database (quantities of substrates consumed, process parameters, biogas and electricity production) which is supplemented by the biogas operator and is updated on a daily basis, and the findings from laboratory research generated in the University laboratory (analyses of FOS/TAC, ammoniacal nitrogen, dry mass, C/N ratio etc.). The financial tab presents the profitability of each substrate based on substrate costs and revenue. The figures are calculated using the biogas efficiency rates and current prices of electricity and certificates. This allows to optimize the biogas plant’s economic performance. By analyzing all parameters listed above, the biogas plant supervision manager can precisely control the stability of the process, prevent inhibition (by monitoring the increase in the concentration of the inhibiting factor, he/she can timely recommend applicable preventive measures to be taken), and optimize the batch mixture for the biogas plant and the economic balance of the entire installation. The whole dataset is presented in a legible, transparent form.
