Comparative analysis of cryogenic distillation and chemical absorption for carbon capture in integrated natural gas liquefaction processes

Latest technological advances and insights into capture and removal of hydrogen sulfide: a critical review

“…In addition, cryogenic distillation requires complex and expensive specialized equipment with high maintenance costs such as refrigeration units, distillation columns and heat exchangers. 371 Furthermore, there are also safety concerns regarding cryogenic distillation as the process involves handling extremely cold materials, which can be hazardous if not properly managed. There is also a risk of leaks or equipment failure, which could result in the release of toxic gases or other safety hazards.…”

“…Last but not least, the process also has a significant environmental impact due to the high energy consumption and the potential for leaks or release of toxic gases. 371…”

“…Cryogenic distillation technology is a process used to separate different components of a gas mixture by cooling the mixture to very low temperatures and then distilling it. 371 Cryogenic distillation technology is one of the most efficient methods used for the simultaneous removal of CO 2 and H 2 S from natural gas streams. 372 Commercially, cryogenic separation is widely utilized for CO 2 separation to fulfill the pipeline requirements.…”

Energetic–Environmental–Economic Assessment of Integrated Different Carbon Capture and Compression Processes for High CO2 Concentration Gas

“…To identify how they would affect TCC, sensitivity analyses of these two critical market factors are performed in this part. The studied ranges of electricity and steam prices are based on the reported values. , Figure a provides the cost changes of the PD and CD processes under different electricity prices, in which the steam price is fixed at $22.86/ton according to the practical industry data. As expected, the TCC of the CD process is more sensitive to electricity prices than the PD process, revealing significant increases with growing prices.…”

Highly efficient capture of CO2 through the synergy of intramolecular amines within piperazine‐derived alcoholamines

“…Carbon capture, utilization, and storage (CCUS) technology is considered to provide an efficient route to achieve carbon neutrality. 7 Among various CCUS technologies, aminescrubbing-based chemical absorption has always been the most practical technology as it offers advantages over other CCUS processes, such as distillation, 8 membrane separation, 9 and adsorption 10 in terms of rapid separation rate, high capture capacity, and long-term reusability, [11][12][13][14] making it more economical and efficient. The absorbent is the key to chemical absorption.…”
