WBA Training | Diagnostics & Prevention of Process Disruption | Wednesday 31 July
July 31 @ 1:00 pm - 5:00 pm
£195.00 – £295.00Online course on Anaerobic Digestion Diagnostics and Prevention of Process Disruption
Who should participate: AD plant operators, developers, consultants, researchers, engineers and anybody engaged in getting the maximum profit from a biogas plant.
Required professional level: the participant should have at least some basic knowledge of chemistry and anaerobic digestion technology.
Lecturer: Prof. eng. Mario A. Rosato, author of “Managing Biogas Plants – A Practical Guide” (CRC Press, 2017).
Programme
Critical review of the current methods for managing biogas plants and outline of the rational method
- Scope and general vision of this course
- The most common methods for biogas plant management, and why to avoid them:
- BMP from tables
- BMP from theoretical formulas (Buswell, Baserga, pFOM)
- BMP as a function of the BOD test
- Titration (a.k.a. FOS/TAC, a.k.a. VFA/TA)
- Electrical conductivity
- Control of the digester with pH or ORP electrodes
- Chemical analysis of the trace elements and (or) inhibitors
- Introduction to the rational method for biogas plant management
- Measuring the VS (or COD) of the feedstock
- Measuring the BMP of the feedstock (a brief comparison between the norms VDI 4630:2006, UNI 11703:2018 and IWA Draft 2016)
- Measuring the specific biological activity of the inoculum (SMA test and the need for its normalisation, hydrolytic, proteolytic and lipolytic activity, comparing additives and pretreatments)
- Measuring the digestion efficiency
- Measuring and energy optimisation of the digester’s stirring
How to optimise the digestion process and prevent its disruption
- Frequent causes of process disruption and how to avoid them. Some study cases.
- Laboratory techniques in anaerobic digestion
- Basics of metrology and error propagation: How to measure accurately, even with coarse instruments
- Difference between accuracy and precision
- Practical application of the error analysis
- Measurement devices for the gas flow and volume from fermentation processes
- volumetric methods
- barometric methods
- Batch and continuous volumetric methods: when to employ one or the other
- Critical review of the literature
