On line seminar
Date: 19th Jan. 2021, from 14:00 to 17:00 CET ( held in English)
This seminar is a new session of the one held on 10th December 2020, to accomodate for those who were not able to attend the first session.
Who should participate: consultants, researchers, engineers and anybody engaged in getting the maximum profit from a biogas plant.
Required professional level: participants should have at least some basic knowledge of chemistry and anaerobic digestion technology.
- 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
- Measurement of the VS (or COD) of the feedstock
- Measurement of the feedstock’s BMP (a brief comparison between the norms VDI 4630:2006, UNI 11703:2018 and IWA Draft 2016)
- Measurement of the specific biological activity of the ’inoculum (SMA test and the need for its normalization, hydrolytic, proteolytic and lipolytic activity, comparing additives and pretreatments)
- Measurement of the digestion efficiency
- Some 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
- Hands-on: virtual practice on measuring BMP with the AMPTS II
Speaker: Prof. Eng. Mario A. Rosato, author of “Managing Biogas Plants – A Practical Guide” (CRC Press, 2017), has a wide ranging experience in anaerobic digestion, with a specific experience in plant diagnostics and process control. As a biogas expert, he actively participated in the working group that created the new UNI 11703:2018 standard for biomethane potential assessment (BMP).
