Carbon capture for decarbonisation of energy-intensive industries: a comparative review of techno-economic feasibility of solid looping cycles

《化学科学与工程前沿（英文）》 2022年 第16卷 第9期   页码 1291-1317 doi: 10.1007/s11705-022-2151-5

摘要： Carbon capture and storage will play a crucial role in industrial decarbonisation. However, the current literature presents a large variability in the techno-economic feasibility of CO2 capture technologies. Consequently, reliable pathways for carbon capture deployment in energy-intensive industries are still missing. This work provides a comprehensive review of the state-of-the-art CO2 capture technologies for decarbonisation of the iron and steel, cement, petroleum refining, and pulp and paper industries. Amine scrubbing was shown to be the least feasible option, resulting in the average avoided CO2 cost of between 62.7 €·tCO2−1 for the pulp and paper and 104.6 €·tCO2−1 for the iron and steel industry. Its average equivalent energy requirement varied between 2.7 (iron and steel) and 5.1 MJth⋅kgCO2−1 (cement). Retrofits of emerging calcium looping were shown to improve the overall viability of CO2 capture for industrial decarbonisation. Calcium looping was shown to result in the average avoided CO2 cost of between 32.7 (iron and steel) and 42.9 €·tCO2−1 (cement). Its average equivalent energy requirement varied between 2.0 (iron and steel) and 3.7 MJth⋅kgCO2−1 (pulp and paper). Such performance demonstrated the superiority of calcium looping for industrial decarbonisation. Further work should focus on standardising the techno-economic assessment of technologies for industrial decarbonisation.

以净零排放为目标的封存驱动型CO2提高采收率方法 Article

刘月亮, 芮振华

《工程（英文）》 2022年 第18卷 第11期   页码 79-87 doi: 10.1016/j.eng.2022.02.010

摘要：

将全球气候变化控制在1.5 ℃以内需要降低温室气体排放，主要是减少二氧化碳（CO2）的排放。可通过驱油过程将CO2封存在油藏地质体中，因此，CO2驱油与封存被视为降低CO2排放的重要手段之一。本研究提出了一种新型的CO2提高采收率（EOR）方法，即封存驱动型CO2提高采收率，其主要目标是通过在油藏中封存尽可能多的CO2来实现CO2净零排放甚至负排放，同时最大限度提高原油采收率。该方法以二甲醚（DME）作为一种高效化学助剂，用于辅助传统CO2 驱提高原油采收率，同时提高CO2封存率。结果表明，DME可提高CO2在原油中的溶解度，有利于CO2的溶解封存；可抑制因CO2的抽提作用造成的原油轻质组分“逃逸”，这对原油可持续开发至关重要。封存驱动型CO2 EOR方法在提高波及效率方面优于传统的CO2 EOR，尤其是在采油后期更为明显；同时，封存驱动型CO2 EOR比传统的CO2 EOR可更有效地提高原油采收率。此外，通过封存驱动型CO2 EOR封存的CO2量远超采出原油燃烧产生的碳排放总量。通过优化开发方案，如水气交替注入，可实现更高的原油采收率和CO2封存率目标。

《机械工程前沿（英文）》 2018年 第13卷 第1期   页码 17-24 doi: 10.1007/s11465-018-0480-3

摘要：

Shaft part rolling is an efficient and green near-net shaping technology offering many advantages, including high production efficiency, high material utilization rate, high product quality, and excellent production environment. In this paper, the features of shaft part rolling are introduced along with the working principles of two main shaft part rolling technologies, namely, cross wedge rolling (CWR) and skew rolling (SR). In relation to this technology, some R&D achievements gained by the University of Science and Technology Beijing are summarized. Finally, the latest developments in shaft part rolling are presented, including SR steel balls, precise forming of camshaft blank by CWR, SR phosphorous copper balls at room temperature, and CWR hollow axle sleeve. Although the shaft part rolling technology has been widely used in China, it only accounts for about 15% of applicable parts at present. Nevertheless, this technology has broad application prospects.

Degradation of chlorinated phenols by nanoscale zero-valent iron

CHENG Rong, WANG Jianlong, ZHANG Weixian

《环境科学与工程前沿（英文）》 2008年 第2卷 第1期   页码 103-108 doi: 10.1007/s11783-008-0009-9

摘要： Chlorophenols (CPs), as important contaminants in groundwater, are toxic and difficult to biodegrade. Recently nanoscale zero-valent iron received a great deal of attention because of its excellent performance in treating recalcitrant compounds. In this study, nanoscale zero-valent iron particles were prepared using chemical reduction, and the reductive transformations of three kinds of chlorinated phenols (2-CP, 3-CP, and 4-CP) by nanoscale zero-valent iron under different conditions were investigated. The transformation process of the CPs was shown to be dechlorination first, then cleavage of the benzene ring. The removal efficiency of the CPs varied as follows: 2-CP > 3-CP > 4-CP. The reactivity of CPs was associated with their energy of lowest unoccupied molecular orbit (). With the increase in initial concentrations of CPs, removal efficiency decreased a little. But the quantities of CPs reduced increased evidently. Temperature had influence on not only the removal efficiency, but also the transformation pathway. At higher temperatures, dechlorination occurred prior to benzene ring cleavage. At lower temperatures, however, the oxidation product was formed more easily.

Effects of hydraulic retention time on net present value and performance in a membrane bioreactor treating

Dawei Yu, Jianxing Wang, Libin Zheng, Qianwen Sui, Hui Zhong, Meixue Cheng, Yuansong Wei

《环境科学与工程前沿（英文）》 2020年 第14卷 第6期 doi: 10.1007/s11783-020-1280-7

摘要： Abstract • The membrane bioreactor cost decreased by 38.2% by decreasing HRT from 72 h to 36 h. • Capital and operation costs contributed 62.1% and 37.9% to decreased costs. • The membrane bioreactor is 32.6% cheaper than the oxidation ditch for treatment. • The effluent COD also improved from 709.93±62.75 mg/L to 280±17.32 mg/L. • Further treatment also benefited from lower pretreatment investment. A cost sensitivity analysis was performed for an industrial membrane bioreactor to quantify the effects of hydraulic retention times and related operational parameters on cost. Different hydraulic retention times (72–24 h) were subjected to a flat-sheet membrane bioreactor updated from an existing 72 h oxidation ditch treating antibiotic production wastewater. Field experimental data from the membrane bioreactor, both full-scale (500 m3/d) and pilot (1.0 m3/d), were used to calculate the net present value (NPV), incorporating both capital expenditure (CAPEX) and operating expenditure. The results showed that the tank cost was estimated above membrane cost in the membrane bioreactor. The decreased hydraulic retention time from 72 to 36 h reduced the NPV by 38.2%, where capital expenditure contributed 24.2% more than operational expenditure. Tank construction cost was decisive in determining the net present value contributed 62.1% to the capital expenditure. The membrane bioreactor has the advantage of a longer lifespan flat-sheet membrane, while flux decline was tolerable. The antibiotics decreased to 1.87±0.33 mg/L in the MBR effluent. The upgrade to the membrane bioreactor also benefited further treatments by 10.1%–44.7% lower direct investment.
