CO₂ liquefaction plays a crucial role in carbon capture and storage initiatives. By capturing CO₂ emissions from industrial processes, we avoid releasing that CO₂ into the atmosphere, thus not incrementing GHG concentration. The subsequent step of CO₂ liquefaction allows for different kind of usage: from safe transportation and permanent storage underground or in depleted oil and gas reservoirs, to its integration into various industrial processes.

As Pietro Fiorentini, we can integrate CO₂ recovery and liquefaction systems with upgrading plants. This allows to capture and transform the off-gas coming from biogas upgrading into high-quality valuable product. With the use of advanced technologies such as membrane upgrading and a new distillation process, our systems can successfully purify and liquefy CO₂ avoiding methane slip form the upgrading process. The final product is liquid food-grade CO₂ that can be used in the food and beverage sector as a green substitute of the fossil CO₂ previously used.

Advantages of the new RTCP machine learning system:

• The Controller Peripheral does not need to know the pressure measurement at the Critical Point in order to set regulation correctly.
• This means there is no longer any need for a communication channel between the two devices, and all related issues are therefore eliminated at source (e.g. to do with point to point communication, energy consumption).
• The M.L. Algorithm protects against partial loss of data from one or both Peripherals
• It is evolutionary and adapts daily to new data
• It is analytical and recognises and filters faults in the data
• It is verifiable and offers the operator all the tools to monitor the performance and degree of reliability of forecasting
• It is controllable and allows the operator to define the level of autonomy of the system (control over sending of the Forecast Function to the Controller)

The new RTCP machine learning system consists of three subjects:

• Peripheral Controller: active subject, forecasts the pressure at the Critical Point and applies it for Regulation.
• Data Logger peripheral: passive subject
• Centre-side Machine Learning algorithm: active subject. Learns the behaviour of the network and models the Controller peripheral.

In fact this method eliminates inaccuracies due to a lot of assumptions, imprecise compromises and structural inconveniences resulting by traditional methods based on estimates and models.

The RTCP System is the innovative solution to adjust automatically and immediately the Critical Point pressure depending on changes in the water demand.

lt continuously monitors network situation and pressure values at critical point (CP) and in real-time acts on PRVs or pumps to minimize pressure and to prevent pressure transients in PMZ.

The water network becomes a reliable and efficient system able to provide the best customer service. lndeed optimal pressure values minimize water losses, energy costs and burst frequency, extending asset lifetimes and reducing operating costs.

This solution is the best practice for active pressure management as recommended by IWA practical approach.

The RTCP System consists of two functional blocks:

• Unit for acquisition and real-time transmission of the pressure measured at CP;
• Control unit which acts on PRV set point to change PMZ inlet pressure keeping the desired pressure value at critical point.

The RTCP System does not require other technologies (eg. remote servers) and does not need periods of auto-learning necessary to other solutions. lndeed, thanks to real-time transmission of CP pressure values, the RTCP System has the actual pressure value in any moment and not an estimated value that will never be exact. Since it is based on real values and not statistical values, the pressure adjustment is the best possible.

The RTCP algorithm is able to recognize a sudden demand of water responding with appropriate supply.

Cryo-polished biomethane liquefaction is an innovative technology that offers significant advantages in the production and utilization of renewable natural gas. This process involves the cryogenic treatment of biomethane, which enhances its purity and energy density, making it a more efficient and environmentally friendly fuel source.

One of the primary benefits of cryo-polished biomethane liquefaction is the increased purity of the final product. The cryogenic process effectively removes impurities such as carbon dioxide, hydrogen sulfide, and other contaminants, resulting in a biomethane stream that meets the highest quality standards. This improved purity translates to higher energy content and reduced emissions when the fuel is combusted.

Additionally, the liquefaction process allows for more efficient storage and transportation. Liquefied biomethane occupies significantly less volume compared to its gaseous counterpart, making it a more practical choice for long-distance transportation and storage in confined spaces.
