1. Remote monitoring of biogas plants: Brazilian cases
Good morning, everyone, my name is William, I work at CIBiogás.
I am here to present two of our projects focus on remote monitoring of biogas plants.
Before talking about our projects, I will briefly contextualize the biogas potential in Brazil.

2. ELECTRICAL POWER MATRIX BRAZIL – 2018
Total of 163 GW Eletrictrical Power
According to the National Electric Energy Agency of Brazil, the installed power in the country in 2018 was 163 GW, less than 1% of this amount came from biogas, approximately 149 MW.

According to the Brazilian Biogas Association, the country has a production potential of 52 billion m³ of biogas / year, equivalent to almost 100 GWh / year, enough to supply approximately 22% of the energy consumed in Brazil in 2018, 472 GWh.

4. BIOGAS BARRIERS IN BRAZIL
Lack of technological development in the biogas sector in Brazil
BIOGAS BARRIERS IN BRAZIL
Lack of skilled labor and suppliers specialized in biogas
High importing costs
But why biogas did not develop in Brazil. 4 are the main reasons:
Lack of technological development
Lack of specialized manpower and suppliers
High costs of importing equipment from other countries
Lack of regulations and public policies to encourage biogas
Lack of specific regulations and public policy

5. MOST COMMON DIGESTER IN BRAZIL
Therefore, the reality of most biogas plants in Brazil is this. Low-technology, low-cost digesters that operate on low solids substrates and consequently low productivity of biogas.

6. 6 80 450 CASE 1 – ITAIPU BIOGAS PLANT
The first CIBiogás project that I will present is a biomethena plant, installed in the Itaipu hydroelectric area. This plant processes 6 tons / day of organic waste, producing 450 m³ of biomethane per day and supplying a fleet of 80 vehicles from Itaipu. 6 80

7. CASE 1 – ITAIPU BIOGAS PLANT
In this plant a remote monitoring and actuation system was developed, which allows the monitoring and operation of all stages of the process using a web platform compatible with PCs and mobile apps. Parameters such as temperature, pressure, flow, composition, etc. are monitored.
The objective of this project was the development of the biogas chain in the region (man power, suppliers, knowledge, market stimulus, etc).  
However, this project does not represent the reality of most biogas plants in Brazil, and the developed supervisory system needed to be adapted to attend these demands.

8. CASE 2- ENTRE RIOS DO OESTE/PR
The second project I am going to present is an agroenergy condominium that is in the startup phase, with commercial start up to June / 2019.
The project is called Entre Rios do Oeste, the same name as the city where it is being implanted. Its technical arrangement is the implantation of digesters in 17 pig farms with a total amount of animals of 39,000 pigs. These farms will be connected by a 21-kilometer gas pipeline that directs the biogas produced to a power plant for electric power generation, with an installed power of 480 kW, which will be used by the public buildings of the city of Entre Rios do Oeste, enough to supply all the consumption, with a surplus of 40% of electric energy. 17

13. Dashboard User Rural Properties LoRa WAN node Measuring sensors Router
For this project it was necessary to develop a monitoring system of low cost, because we have 17 biogas plants separated by 21 kilometers of pipeline. The solution was to instal biogas sensors (pressure, temperature and flow meters) to enable automation and remote monitoring of the biogas dispatch system to the power plant. These sensors were connected to a LoRa node device that sends the data through a radio protocol to a LoRa Gateway device installed in the Power Plant whitch collects, stores, sends and makes available the information to a web system that will be accessed by users for viewing the data.
