Evaluation of the performance and economic viability of a novel low temperature carbon capture process

Abstract

A novel Advanced Cryogenic Carbon Capture (A3C) process is being developed due to its potential to achieve high CO 2 capture efficiencies using low cost but high intensity heat transfer to deliver a much reduced energy consumption and process equipment size and cost. These characteristics, along with the absence of process chemicals, offer the potential for application across a range of sectors. This work presents a techno-economic evaluation for applications ranging from 3% to 35% CO 2 content.

Review of Cryogenic Carbon Capture Innovations and Their Potential Applications

“…Willson et al [25] proposed the use of a moving packed bed of cold bed material to capture CO 2 without using multiple packed beds operating in cycles. The moving packed bed captures CO 2 frost on the surface of the bed material.…”

“…The estimated specific energy of CO 2 capture was calculated by Willson et al for a number of different applications, the most effective application being biogas upgrading with a specific energy of 263 kWh/tonne CO 2 (0.95 MJ/kg CO 2 ) [25].…”

Production of Biomethane From Agricultural Waste Using a Cryogenic Carbon Capture Process

“…The bed is then recirculated through a further heat exchanger for cooling to the desired inlet temperature. More details on the A3C process can be found in [8].…”

“…Therefore, this paper presents a novel advanced cryogenic carbon capture (A3C) technology that overcomes some limitations of previous cryogenic systems by using a moving bed of metallic beads as a heat transfer medium and frost capture surface. Prior work detailed in [8] modelled the performance and estimated costs of a 720 Nm 3 /h biogas application of the A3C process using Aspen Plus®. The work assumed that the biogas consisted of the two major gases methane and carbon dioxide at 65% and 35% vol., respectively.…”

Biomethane production using an integrated anaerobic digestion, gasification and CO2 biomethanation process in a real waste water treatment plant: A techno-economic assessment

“…Among the different options to upgrade biogas, such as chemical/physical absorption, membrane and cryogenic technologies [9] [10], the Power to Gas (P2G) concept has received increased interest in the recent years [11]. The idea behind the P2G technology is that electricity can be utilised to hydrolyse water and the produced hydrogen will react with the CO 2 in the biogas to form methane though the biological Sabatier reaction, Eq.…”
