“…Deployment at scales below 10 kg·s –1 would be unlikely as the total cost becomes dominated by capital costs. Advancements in process intensification, for example, rotating packed beds, , could potentially provide significant reductions in the capital cost and improve the economic viability of smaller scale absorption systems. In applications where capture costs of absorption may be considered expensive, there are potential opportunities for other technologies such as adsorption and membranes.…”

As more countries commit to a net-zero GHG emission target, we need a whole energy and industrial system approach to decarbonization rather than focus on individual emitters. This paper presents a techno-economic analysis of monoethanolamine-based post-combustion capture to explore opportunities over a diverse range of power and industrial applications. The following ranges were investigated: feed gas flow rate between 1–1000 kg ·s–1, gas CO2 concentrations of 2–42%mol, capture rates of 70–99%, and interest rates of 2–20%. The economies of scale are evident when the flue gas flow rate is <20 kg ·s–1 and gas concentration is below 20%mol CO2. In most cases, increasing the capture rate from 90 to 95% has a negligible impact on capture cost, thereby reducing CO2 emissions at virtually no additional cost. The majority of the investigated space has an operating cost fraction above 50%. In these instances, reducing the cost of capital (i.e., interest rate) has a minor impact on the capture cost. Instead, it would be more beneficial to reduce steam requirements. We also provide a surrogate model which can evaluate capture cost from inputs of the gas flow rate, CO2 composition, capture rate, interest rate, steam cost, and electricity cost.

“…Mass transfer performance intensification comparison of these two reactors was executed in some investigations. For instance, Tay et al 25 compared the mass transfer intensification performance of microreactors, rotating packed-bed reactors, hollow fiber membrane contactors, and high frequency ultrasonic reactors for CO 2 removal from natural gas under offshore conditions. This analysis was benchmarked by the intensification and size reduction factors, and operating penalties.…”

“…Hybrid processes have received much attention nowadays because of overcoming the demerits of standalone technology. − Absorption is classified into physical and chemical, and physical absorption depends on the solubility of CO 2 in absorbents and needs elevated pressure, while CO 2 can be easily captured using chemical absorbents at atmospheric pressure . Amine-based absorption is the most matured, widely implemented and cost-effective PCC process, ,, and frequently used amines for CO 2 capture are monoethanolamine (MEA), diethanolamine (DEA), N -methyldiethanolamine (N-MDEA), and 2-amino-2-methyl-1-propanol (AMP), respectively.…”

Process intensification for CO 2 absorption using microreactors has received growing interest from both academia and industry because of their great ability to overcome the mass transfer resistance across the phases boundaries, giving rise to significant improvement in process efficiency. Mass transfer is strongly linked with two-phase flow patterns of CO 2 -absorbent in microreactors and, subsequently, overall volumetric mass transfer coefficient (ka) intensification relies on hydrodynamics, microreactor structures and applied absorbents. Reviewed literature on this subject indicated that the Taylor flow pattern, spiral and meandering microreactor structures, and primary and secondary amines absorbents were preferred to use for the CO 2 absorption in microreactors. Moreover, ka models developed through offline and online characterizations were presented to analyze the contribution of liquid film and bubble caps in mass transfer. Economic analysis was executed to assess the operating feasibility of microreactors at industrial scale throughputs of feed gas and absorbent. The results indicated that the capital expenses of microreactors were significantly higher than those of conventional absorbers because of their extensive number of units and complex design of flow distribution network requirements with high throughputs. However, microreactors exhibited lower operating expenditures than conventional absorbers because of their excellent transport characteristics. Finally, the persisting challenges and remarking conclusions are presented relating to the implementation of microreactors for CO 2 absorption.

“…In recent years, the number of weather-related natural disasters has grown sharply as have the costs associated with related losses [ 1 , 2 ]. Storm disasters, such as typhoons, hurricanes, tornadoes, and storm surges, significantly impact offshore oil and gas production, and can cause operational shutdown, facility damage, casualties, ecological crises, and even serious social unrest [ 3 , 4 , 5 ]. During Hurricane Harvey (2017), about 25% of the oil and gas production in the Gulf of Mexico was shut down, and 105 production platforms (15% of the total) were closed, causing a fluctuation in oil and gas prices [ 6 ].…”

Modeling the Evolution of Major Storm-Disaster-Induced Accidents in the Offshore Oil and Gas Industry

Storm disasters are the most common cause of accidents in offshore oil and gas industries. To prevent accidents resulting from storms, it is vital to analyze accident propagation and to learn about accident mechanism from previous accidents. In this paper, a novel risk analysis framework is proposed for systematically identifying and analyzing the evolution of accident causes. First, accident causal factors are identified and coded based on grounded theory (GT). Then, decision making trial and evaluation laboratory (DEMATEL) is integrated with interpretative structural modeling (ISM) to establish accident evolution hierarchy. Finally, complex networks (CN) are developed to analyze the evolution process of accidents. Compared to reported works, the contribution is threefold: (1) the demand for expert knowledge and personnel subjective influence are reduced through the data induction of accident cases; (2) the method of establishing influence matrix and interaction matrix is improved according to the accident frequency analysis; (3) a hybrid algorithm that can calculate multiple shortest paths of accident evolution under the same node pair is proposed. This method provides a new idea for step-by-step assessment of the accident evolution process, which weakens the subjectivity of traditional methods and achieves quantitative assessment of the importance of accident evolution nodes. The proposed method is demonstrated and validated by a case study of major offshore oil and gas industry accidents caused by storm disasters. Results show that there are five key nodes and five critical paths in the process of accident evolution. Through targeted prevention and control of these nodes and paths, the average shortest path length of the accident evolution network is increased by 35.19%, and the maximum global efficiency decreases by 20.12%. This indicates that the proposed method has broad applicability and can effectively reduce operational risk, so that it can guide actual offshore oil and gas operations during storm disasters.
