Gas Stabilizer 

it is a tool that optimizes the performance of capturing biogas by minimizing the emission of bad odors and maximizing the quantity of fuel resource (CH4) available for energy recover

Problems: 

a. Variability of CH4 methane concentrations in the biogas sent to the recovery plant

b. It is not possible to know in real time which lines are active in the collection of biogas (production lines)

c. When traditional collection systems are not sufficiently efficient, "free emission" biogas cause bad smell

d. Lack of energy production caused by the inefficiency of traditional biogas collection systems

e. Variable yields of biogas powered energy recovery plants: the variability of the biogas composition can decrease yields, shorten maintenance times and reduce the life of the energy recovery plant (e.g. cogeneration engine)

f. Regulation of biogas collection systems carried out manually by specialized technical personnel with the aid of portable analysis instruments

g. Hours of work used by specialized technical staff to perform adjustments of the biogas collection systems in manual mode

h. Bi-weekly periodicity of the activities for carrying out the adjustments of the biogas collection systems in manual mode

i. Plants that produce "poor biogas" (with low CH4 methane content) often do not perform any energy recovery

j. In some plants such as landfills, the production of biogas tends to decrease naturally over time both in quantitative terms (e.g. tons produced) and in qualitative terms (e.g. lower% vol of CH4 contained in biogas)

k. Old collection systems, systems with efficiency problems

Solutions: 

a. Keeps the parameter of the CH4 methane concentration present in the biogas sent to the recovery plant constant (over the range of values ​​set automatically)

b. It monitors the efficiency of collection of each individual production line by continuously measuring the depression applied to it and reporting any anomalies on which to intervene

c. Optimizes the collection of biogas by minimizing (if not negligible) the odor emission for the benefit of energy recovery

d. Optimizes the collection of biogas allowing the achievement of scheduled production

e. Keeps the composition of the biogas sent to the energy recovery plant constant (over the range of values ​​set automatically), increasing its yield, prolonging its useful life and regularizing the scheduled maintenance periodicity

f. Performs the regulation of the biogas collection systems in automatic mode also remotely thanks to the provision of a continuous analysis system and a software for setting the regulation parameters

g. Automatically adjusts each collection line, even remotely

h. Performs the regulation of the biogas collection systems continuously and automatically even remotely

i. It can be combined with poor gas recovery systems (like oxidizers can be) which, in order to function, require a constant supply of the fuel mixture both in quantitative and qualitative terms

j. Maintains the efficiency of collection on the values ​​(set automatically) compatible with the maximum production standard

k. It can also be applied in existing and old collection systems, to which it brings increases in biogas extraction efficiency

Strenghts of Gas Stabilizer  

- Optimization of the quantity and quality of biogas fuel for energy recovery plants with consequent increase in production;

- The simplicity of the equipment to be installed both in existing plants and in new construction plants;

- The simplicity of management, maintenance and adjustment;

- It is made up of modular instrumentation and adaptable to the different systems;

- Automation, which guarantees greater efficiency and greater coverage of action;

- The acquired data are saved and archived and allow the analysis of the functioning and production trend over time;

- The characteristics of continuous self-regulation on values ​​set to reach the optimal value of energy potential making it available for treatment and recovery;

- Continuous monitoring of the collection system allows you to check all the lines and identify any operating problems by signaling the malfunction. Maintenance can therefore be targeted, precise and efficient;

- The 'remote control' of the control system allows verification and management from anywhere and at any time of the day.

Enviromental and Economic return

- The optimization of the uptake determines the reduction of the bad smell linked to the presence of "free emissions" of biogas;

- Biogas contains variable percentages of methane CH4 classified by the scientific literature as very active "greenhouse gas"; the optimization of the collection of biogas determines an improvement from the point of view of the atmospheric emissions of gases responsible for the intensification of the greenhouse effect, as it reduces CH4 emissions; in particular if the captured methane is to be used as fuel (instead of dispersed in the atmosphere) it should be remembered that the CO2 produced by the combustion of methane allows to balance the balance of carbon dioxide emitted into the atmosphere: in fact the CO2 emitted from the combustion of biogas is the same CO2 set by plants (or taken indirectly by animals through plants), as opposed to what happens for CO2 emitted ex novo from the combustion of fossil fuels;

- The increase in the collection of biogas in quantitative terms (average increase from 5% to 30%);

- The improvement and stabilization of the quality of the biogas destined for treatment and recovery;

- The increase in the production of electricity and / or heat;

- The decrease in the workforce used for manual adjustment activities and for routine maintenance (by virtue of targeted interventions highlighted by continuous diagnostics);

- The 'remote control' of the control;

- The increase in earnings from energy recovery (average increase from 5% to 30%);

- The possibility of facilities and incentives for installation, based on the country and the historical installation period
