Cryo Collect

CO2 Capture Technology

Carboliq is designed to capture CO2 from the lean off gas of the biogas upgrading unit in order to produce pure, food-grade quality liquid CO2. Due to the versatility and flexibility of the design, various gas sources from various industries are used to recover and liquefy CO2 at different quality specifications.

Our purification and liquefaction process consists of a series of units including compression, drying, condensation (using only natural refrigerants) and stripping.

The units preceding compression in our purification and liquefaction process can be adapted according to the impurities and composition of the treated feed gas.

Besides providing an additional revenue stream by producing liquid bioCO2, Carboliq improves the carbon intensity score of the facility by reducing the methane slip in upgrading. In addition, on-site CO2 recovery increases the independence of CO2 consumers.

Lift Technology

Lift aims to boost energy from a low to a high temperature via two cascaded refrigeration cycles. This boost provides both cold and hot usages which otherwise were direct consumers of energy.

The innovation of this technology consists in its modularity as it can operate in 3 different modes according to the season and the energy needs: Heating mode alone, cooling mode alone, heating and cooling mode. Every mode is also capable of operating at a large temperature range.

Besides being an interesting technology for the industry, Lift is also an attractive design for residential applications as it can provide flexible heating and cooling for water and air conditioning.

• Modularity in 3 different modes

• High efficiency

• Low GWP refrigerants

• Residential and industrial applications

• High temperature ranges between 70-90°C
