Pilot tests of CO2 capture in brick production industry using gas–liquid contact membranes

Abstract

It is generally accepted that carbon capture and storage strategies will play a crucial role for mitigating CO 2 emissions at short-and mid-term scenarios. In this study, a membrane gas absorption process was assessed as potential candidate method for CO 2 capture in a Greek brick production industry. The membrane contactor pilot unit was installed near the flue, where a slip stream of the flue gases was continuously sampled and fed in the hollow fiber membrane module. A 0.25 M aqueous diethanolamine solution was used as a typical solvent for CO 2 capture. The % CO 2 removal was chosen as a typical performance indicator and the liquid to gas flow ratio was chosen as the main controlling variable of the process. The test results indicate that almost complete CO 2 removal can be attained with a liquid to gas flow rate around 1, demonstrating the high potential of the proposed technology.

A Step in Carbon Capture from Wet Gases: Understanding the Effect of Water on CO2 Adsorption and Diffusion in UiO-66

“…The management and abatement of greenhouse gases, with their effect on climate change can be considered as one of the great worldwide challenges of our century. Along with better energy efficiency and the replacement of fossil fuels by renewable energy, carbon capture and storage (CCS) is an important tool to meet this challenge. , Furthermore, if the geologically stored carbon is captured from the atmosphere (direct air capture, DACCS) or from bioenergy conversion (BECCS), then both DACCS and BECCS, as negative emission technologies, are important means to remove historical emissions. , The first brick in the CCS chain is capture, which is often considered the most expensive block . This explains why significant research and development is devoted to finding economic alternatives to the canonical amine scrubbing approach, where the thermal regeneration step tends to be highly energy consuming.…”

Adsorption-based methods can be considered of interest, although they equally suffer from their own disadvantages such as insufficient CO 2 product purity.…”

Modelling, simulation, and membrane wetting estimation in gas‐liquid contacting processes

“…In the past, experimental results of both reacting and non‐reacting solvents were presented for the efficient removal of CO 2 from the lumen side . In this study only physical absorption is considered for the modelling case in order to avoid the complexity of reacting fluids properties and possible heat transfer aspects (see e.g.…”

From quarry to carbon sink: process-based LCA modelling of lime-based construction materials for net-zero and carbon-negative transformation

“…Only a few articles explored strategies involving solvents, sorbents, mineralization, and alkalinization of waste materials, resulting in relatively modest technological advancements. [12][13][14][15] Nevertheless, since 2020, we have witnessed ground-breaking innovations in traditional lime manufacturing, with a particular focus on kiln designs incorporating direct separation technology (DST), enabling the direct capture of CO 2 during the calcination of CaCO 3 . 16 Noteworthily, EU initiatives, such as LEILAC1 and LEILAC2 (https://www.leilac.com/), boasting a combined budget of 55 million euros, have been dedicated to the development of the CALIX kiln equipped with DST technology.…”
