This presentation will focus on the benefits of an integrated solution whereby all aspects of the downstream carbon capture components including gas compression, conditioning and measurement are engineered as a complete offering. Lead time, project execution risks, and process efficiency are all improved as a fully integrated offering. The core technology of the downstream carbon capture operations are typically procured from separate companies under the direction of an EPC (Engineering, Procurement and Construction) company. In best efforts the of the EPC companies, assessments can take time and miss critical details in assessing the core units of the downstream equipment pertaining to the compressor, gas conditioning, and measurement equipment.

Gas conditioning equipment contains deoxygenation, dehydration, and other equipment targeting removal of impurities to reach the offtake agreement specifications. This gas conditioning package is located between the upstream and downstream sections of the compressor and is critical to the performance of the compressor. Engineering decisions during the design stage of the process can have substantial impacts on the operation of the overall capture plant. Measurement equipment is typically located at the supercritical stage of the process downstream of the downstream compression section. The mass flow meters of the supercritical CO₂ are well positioned in the supercritical phase. There are measurements of impurities that are placed about the same mass flow meters. This poses some challenges in the accuracy of measurement as some of the impurities are easier to measure in the gas phase of CO₂ as compared to the supercritical phase.

As the integration of these core pieces of equipment can take several months during the project, it can be advantageous to utilize the experts that support the same technology to design the best solution for the overall offering to compress, condition and measure the CO₂ fluid stream. The engineering of the integrated solution can take place outside of the schedule of the project and allow for standardization of aspects that would normally not have time to do within the project. This further reduces lead times and project risk. The process design aspects can be addressed in a structured manner to increase standardization efforts while assuring highest operating efficiency through proper placement of equipment and full use of waste heat from the process to reduce operating costs.
