Technology Evolution in Membrane-Based CCS

Abstract

In recent years, many CO2 capture technologies have been developed due to growing awareness about the importance of reducing greenhouse gas emissions. In this paper, publications from the last decade addressing this topic were analyzed, paying special attention to patent status to provide useful information for policymakers, industry, and businesses and to help determine the direction of future research. To show the most current patent activity related to carbon capture using membrane technology, we collected 2749 patent documents and 572 scientific papers. The results demonstrated that membranes are a developing field, with the number of applications growing at a steady pace, exceeding 100 applications per year in 2013 and 2014. North American assignees were the main contributors, with the greatest number of patents owned by companies such as UOP LLC, Kilimanjaro Energy Inc., and Membrane Technology and Research Inc., making up 26% of the total number of published patents. Asian countries (China, Japan, and Korea) and international offices were also important knowledge sources, providing 29% and 24% of the documents, respectively. Furthermore, this paper highlights 10 more valuable patents regarding their degree of innovation and citations, classified as Y02C 10/10 according to the Cooperative Patent Classification (CPC) criteria.

Structural Characteristics and Environmental Applications of Covalent Organic Frameworks

“…In recent years, adsorption-(entrapment) and membrane (size exclusion)based purification have attracted immense research and industrial interest due to their low energy consumption as well as simple and environmentally friendly operation. Various amorphous materials such as hyper-cross-linked polymers (HCPs) [1,2], porous organic polymers (POPs) [3,4], conjugated microporous polymers (CMPs) [5][6][7], and activated carbon [8][9][10]; and crystalline materials such as metal-organic frameworks (MOFs) [11][12][13][14] and zeolites [15][16][17][18][19], have shown excellent preliminary separation performance. Covalent organic frameworks (MOFs) [11][12][13][14] and zeolites [15][16][17][18][19], have shown excellent preliminary separation performance.…”

Covalent organic frameworks (COFs) are a class of crystalline framework material synthesized from purely organic building blocks.…”

Innovative Gas-Liquid Membrane Contactor Systems for Carbon Capture and Mineralization in Energy Intensive Industries

“…Novel technologies for CCUM involve the use of gas-liquid membrane contactors for post-combustion capture. Hollow fiber membrane contactors are well established in the field of gas separation/bubbling/extraction applications since very large and well-defined surface areas can be obtained in hyper compact membrane modules [ 21 , 22 ]. Using a hydrophobic microporous membrane two different modes of operation can be identified depending on operating pressure ( Figure 1 ): (a) the membrane contactor mode ( Figure 1 a), in which an immobilized gas-liquid interface is formed at the pores’ mouth in the liquid side, by keeping the liquid pressure higher than the gas pressure and lower than the breakthrough pressure, that is, the pressure where liquid enters into the pores of a hydrophobic membrane (P br > P liq > P gas ) and (b) the membrane bubbling reactor mode, ( Figure 1 b), in which gas enters in the liquid phase in the form of nano-bubbles, by keeping the gas pressure higher than the liquid pressure (P gas > P liq ).…”
