Industrial Refrigeration for Biogas Plants

Chillers for Biogas Plants

A further use of chillers/chillers is in biogas plants: a gas mixture, derived from organic substances and highly energetic and ‘green’. The role of the chiller is to cool the biogas before it enters the cogeneration engine. Reliability and safety are the pluses that chillers must guarantee.

Examples of applications: biogas production for cogeneration plants.

Main requirements: reliability, security and continuity of work 24 / 365 days a year.

Biogas Chillers: at a glance

Let us look in detail at how chillers for biogas plants work, starting with the general operation of this type of energy source.

Anaerobic digestion is a complex biological process in which, in the absence of oxygen, organic matter is converted into biogas, a renewable and sustainable energy source.

There are specific players that build turnkey biogas plants and companies that provide the cogeneration and biogas treatment package.

The biogas needs to be cooled down to around 5° C: it is in this context, and before it enters the cogeneration engine, that the cooling chiller comes into play, which is used to dehumidify and cool the biogas. As these are aggressive environments, the cooling systems must be safe, robust and ensure smooth operation with little need for maintenance, as the process is continuous 24 hours a day.

Turnkey Industrial Refrigeration Plants

A refrigeration system is more than a single chiller: heat exchangers, hydraulic connections, additional cooling devices also come into play to support your production process.

RW / EFC ax Liquid Free-Cooling Chiller

The secret of this system is the combination of the refrigeration section and the free-cooling section depending on the time of day and year: the first mode allowed by these liquid chillers takes advantage of the normal operation of a refrigeration circuit, the second allows cold outside air to be directly conveyed to the fluid to be cooled: maximum efficiency, minimum energy use due to the clear separation between the two sections.

PAD-V Adiabatic Cooler Condenser

Adiabatic liquid coolers and gas condensers PAD-V series are offered where the focus is particularly on rational use of water and energy thanks to a dual operating principle, during hot and cold seasons, and thanks to the control panel that optimizes system operating parameters.

Low-Temperature Industrial Chiller for a Biogas Player

The biomass sector is one of the most interesting for its implications related to energy recovery: Frigofluid supplied an industrial chiller to an international broker, with final installation in Colombia.

Preliminary Assessment

Many interlocutors come to us with a very general idea of their industrial refrigeration needs: this is normal. That's why we stimulate the sharing of technical information.

Customized Design

We believe that integration with the best accessories on the market and the careful and 'unified' selection of internal components can make the difference.

Custom Chillers and Turnkey Plants

Production facilities and the characteristic of the installation area also have important effects on the design: because one cannot stop at the listed solutions.
