osmosis concentrate and CaCO₃ recovery: A case study on the coalchemical industry

Jiandong Lu, Shijie You, Xiuheng Wang

《环境科学与工程前沿（英文）》 2021年第15卷第1期 doi: 10.1007/s11783-020-1301-6

摘要： Abstract • Forward osmosis (FO) coupled with chemical softening for CCI ROC minimization • Effective removal of scale precursor ions by lime-soda ash softening • Enhanced water recovery from 54% to 86% by mitigation of FO membrane scaling • High-purity CaCO3 was recovered from the softening sludge • Membrane cleaning efficiency of 88.5% was obtained by EDTA for softened ROC Reverse osmosis (RO) is frequently used for water reclamation from treated wastewater or desalination plants. The RO concentrate (ROC) produced from the coal chemical industry (CCI) generally contains refractory organic pollutants and extremely high-concentration inorganic salts with a dissolved solids content of more than 20 g/L contributed by inorganic ions, such as Na+, Ca2+, Mg2+, Cl−, and SO42−. To address this issue, in this study, we focused on coupling forward osmosis (FO) with chemical softening (FO-CS) for the volume minimization of CCI ROC and the recovery of valuable resources in the form of CaCO3. In the case of the real raw CCI ROC, softening treatment by lime-soda ash was shown to effectively remove Ca2+/Ba2+ (>98.5%) and Mg2+/Sr2+/Si (>80%), as well as significantly mitigate membrane scaling during FO. The softened ROC and raw ROC corresponded to a maximum water recovery of 86% and 54%, respectively. During cyclic FO tests (4 × 10 h), a 27% decline in the water flux was observed for raw ROC, whereas only 4% was observed for softened ROC. The cleaning efficiency using EDTA was also found to be considerably higher for softened ROC (88.5%) than that for raw ROC (49.0%). In addition, CaCO3 (92.2% purity) was recovered from the softening sludge with an average yield of 5.6 kg/m3 treated ROC. This study provides a proof-of-concept demonstration of the FO-CS coupling process for ROC volume minimization and valuable resources recovery, which makes the treatment of CCI ROC more efficient and more economical.

make the production of methanol/DME “GREENER”—Integration of wind power with modern coalchemical industry—

Weidou NI , Zhen CHEN , Zheng LI , Jian GAO ,

《能源前沿（英文）》 2009年第3卷第1期页码 94-98 doi: 10.1007/s11708-009-0012-2

摘要： The urgency and necessity of alternative fuels give an impetus to the development of modern coal chemical industry. Coal-based methanol/DME is the key element of this industry. Wind power, whose installed capacity increased at a rate of more than 100% in recent years, has the most developed technologies in renewable energy. However, there still exist many unsolved problems in wind power for on-grid utilization. A new integrated system which combines coal-based methanol/DME production with wind power is proposed in this paper. In this system, wind power is used to electrolyze water to produce H and O. The O is fed to the gasifier as gasification agent. The H is mixed with the CO-rich gas to adjust the H/CO to an appropriate ratio for methanol synthesis. In comparison with conventional coal-based methanol/DME system, the proposed system omits the expensive and energy-consuming ASU and greatly reduces the water gas shift process, which brings both advantages in the utilization of all raw materials and significant mitigation of CO emission. This system will be attractive in the regions of China which have abundant wind and coal resources.

新型煤化工的生命周期碳排放趋势分析

武娟妮,张岳玲,田亚峻,谢克昌

《中国工程科学》 2015年第17卷第9期页码 69-74

摘要：

近年来新型煤化工的发展势头强劲，不仅使煤转化过程的碳排放有大幅增长的趋势，更会带动整个产业链碳排放的增长。为了全面认识新型煤化工发展给气候变化带来的潜在影响，本文采用生命周期评价的方法，以煤制烯烃、煤间接液化、煤直接液化、煤制天然气作为新型煤化工的代表，分析了从煤炭生产到产品消费的整个产业链的碳排放现状和趋势。结果显示，从生命周期的角度认识煤化工发展带来的碳排放潜力，中期新型煤化工生命周期CO₂eq（CO₂当量）排放量是现状的10倍，远期甚至达到现状的21倍，新型煤化工发展呈现过热势头，这给我国的碳减排目标带来不容忽视的压力，其中尤以煤制天然气、煤经甲醇制烯烃和间接液化发展潜力较大；分析表明，整个产业链的碳排放主要来自于煤转化过程，约占54 %~63 %，然而该环节排放的CO₂纯度较高，适于碳捕集、利用和封存(CCUS)，可以显著降低新型煤化工快速发展给气候变化带来的影响；其次，新型煤化工上下游产业链碳排放约占37 %~46 %，其中用电导致的间接排放占7 %~15 %，可通过推广超临界和超超临界发电技术以及高压和超高压输电技术减排。

Management and Practice of Large-Scale Modern Coal Enterprises

An Wang

《工程管理前沿（英文）》 2014年第1卷第1期页码 13-17 doi: 10.15302/J-FEM-2014004

摘要： As the coal-dominated energy structure will remain unchanged in the short term, the sustainable development of the coal industry is still serving as one of the foundations for the sound development of the national economy. The construction of modernized mines based on "four orientations", that is, orientations of scale production, modern technology and equipment, informationized management and professional working team, has been rapidly enhancing its development in the recent decade. However, in the next decade or an even longer period, the industry, with the energy centre shifting to the West of China, will be exposed to new options and development in the layout, structure, model, technology, etc.

Air pollutant control and strategy in coal-fired power industry for promotion of China’s emission reduction

Weiliang WANG, Bo LI, Xuan YAO, Junfu LYU, Weidou NI

《能源前沿（英文）》 2019年第13卷第2期页码 307-316 doi: 10.1007/s11708-019-0620-4

摘要： Coal-fired power industry has always been the major power source in China. As coal-fired power industry consumes around a half of China’s coal production, it is always thought to be a big air pollutant emission source. As more and more strict legislations in coal-fired power industry have been issued by the government, the emission performance in coal-fired power industry has been drastically reduced recently. Based on a brief review of the development of emission control in China’s coal-fired power industry, the affecting mechanism among the development of installed capacities of emission control device, pollutant emission, and emission performances in coal-fired power industry is studied. According to a systematic study on the development of emissions of classified categories, the role of coal-fired power industry as a pollutant source is reevaluated. It is found that, coal-fired power industry has contributed the most to China’s emission reduction, and the barycenter of air pollutant emission has been transformed to other high energy consumption industries, like heat, iron/steel, and cement. Then some development strategies are suggested, such as maintaining the current emission standard in coal-fired power industry; expending the coal-fired power emission standards to categories of heat generation and supply, nonmetallic mineral production and ferrous metals smelting and processing; and controlling other heavy metal by consulting the method of Hg control.
