CO₂ recovery engineering for biogas and dry ice
Solveno Technologies supports your CO₂ recovery project from the first feasibility assessment to system integration and implementation. We work with CO₂-rich off-gas from biogas upgrading and gas recovered during dry ice production.
Low electricity consumption is central to our system design. We assess your gas stream, required liquid CO₂ quality and operating profile to develop a suitable technical solution and evaluate its business case. Our engineering connects process requirements with equipment selection, site interfaces and the practical delivery of your installation.

CO₂ project engineering: from feasibility to operation
We define the engineering scope around your project stage. A first assessment can establish feasibility and investment assumptions before detailed design or equipment supply is commissioned.
Feasibility and business case: We review gas flow, composition, inlet conditions, operating hours and the intended CO₂ application. We assess electricity costs, usable liquid output and total installed investment. For biogas projects, the assessment includes potential CO₂ sales; for dry ice recovery, the liquid CO₂ purchases that can be replaced.
System selection and design: We select the configuration and develop the agreed engineering package. Depending on scope, this includes PFDs, P&IDs, piping, equipment layout and technical documentation. Energy consumption and recovery are assessed together under the specified operating conditions.
Site integration: For biogas upgrading, we coordinate the CO₂ off-gas interface and any proposed methane-containing return stream with the upgrading installation. For dry ice production, we assess gas collection and the return of recovered liquid CO₂. Utilities, storage, controls and installation responsibilities are defined with your team.
Construction, commissioning and handover: For projects including equipment supply, we support construction, quality control, installation and commissioning within the agreed scope. Acceptance criteria and handover documentation are defined before delivery.
Operational support and maintenance: Maintenance and support arrangements can be agreed for the supplied installation, taking account of its operating profile and site requirements.

We assess electricity costs, usable liquid output and total installed investment.

Low electricity consumption
Energy efficiency is a central design priority. We assess electricity consumption per tonne of usable liquid CO₂ alongside recovery yield, product specification and your operating conditions.
Natural-refrigerant technology
Our recovery systems use R744, CO₂ itself, as a natural refrigerant. Cooling conditions and refrigeration requirements are considered as part of the complete installation.
A project-specific business case
We connect technical assumptions with electricity costs, annual output, CO₂ sales or avoided purchases, maintenance and site investment. This makes the main economic drivers visible before investment decisions.
Technical expertise for your CO₂ project
Connected engineering disciplines
Our engineering brings together process requirements, PFDs, P&IDs, piping, equipment layouts and technical documentation. Electrical design is coordinated with a specialist partner.
Modular equipment, defined interfaces
We combine our recovery equipment with project-specific integration. Connections to upstream production, utilities, storage and controls are defined with the parties responsible for each part of the site.
Engineering informed by installation development
Our own CO₂ recovery development connects design work with assembly, access, maintenance and operation. These practical considerations inform the engineering of your project.
Engineering around your gas stream and site
A standard recovery unit still needs project-specific integration. Gas composition, available space, cooling conditions, electrical supply and liquid CO₂ storage influence the final design and installed cost.
For CO₂ recovery from biogas upgrading, engineering focuses on the CO₂-rich stream after methane separation. For CO₂ recovery from dry ice production, it focuses on collecting and reliquefying production gas for reuse.

Start with your project data
Share the source of your CO₂, gas flow and composition, inlet pressure and temperature, annual operating hours, electricity price and intended liquid CO₂ use. Indicate whether you need a feasibility assessment, integration engineering or a project including equipment supply.
We use these inputs to identify the next engineering step and the information still required for a technical and economic assessment.
