Synergetic Management Theory for Coal-Based Energy Engineering and the Engineering Practice of Shenhua

Wen Ling

《工程管理前沿（英文）》 2016年第3卷第1期页码 1-8 doi: 10.15302/J-FEM-2016005

摘要： To deal with problems in synergetic development of coal-based energy engineering, this paper, guided by the philosophy of engineering, proposes the synergetic management philosophy of “factors coordination, systems synergy, dynamic optimization and three-dimension planning.” The paper also establishes the synergetic management system characterized by systems factor synergy, resource-environment synergy and systems boundary extension and supported by the “two-wheel driven” management innovation and technological innovation. In addition, the paper presents a multi-objective dynamic optimization model for energy engineering, designed based on Shenhua’s own engineering practice, to analyze Pareto optimal solution in three scenarios: best resource allocation, minimal environmental impact and maximal value creation. This provides important reference to synergetic development strategies and decision-making in engineering management.

Synergistic utilization of coal and other energy – Key to low carbon economy

Weidou NI, Zhen CHEN

《能源前沿（英文）》 2011年第5卷第1期页码 1-19 doi: 10.1007/s11708-010-0136-4

摘要： In China, coal is a dominant component of energy mix, and it is expected to remain as such over the next 30 to 40 years. Coal is expected to be used even more in power generation. The direct combustion of coal already has been causing severe pollution and ecological degradation, and it is quite difficult to address the need to reduce greenhouse gas (GHG) given the direct combustion of coal. Therefore, the polygeneration system based on coal gasification, which is one of the major examples of synergistic utilization of coal, is proposed. It is a comprehensive solution to meet the energy challenges China is facing. Furthermore, the synergy of fossil fuels (especially coal) with renewable energy, the synergy of different kinds of energy for energy storage, the synergy of centralized and distributed supply of different kinds of energy, and the synergy of different kinds of energy in smart energy grid (power, gas, heat, and water) are the keys to making China a low-carbon economy. Carbon dioxide (CO ) mitigation in China should begin from the coal-chemical industry given their accumulated relevant experiences. The mitigation process should gradually be transformed into the “IGCC+ polygeneration+ CCUS”. The objectives of this paper are to describe the synergistic utilization of coal, and to analyze the synergy of coal with other energy resources, and to propose the scientific and technological problems to achieve these synergies.

Life cycle assessment and economic analysis of HFC-134a production from natural gas compared with oil-basedand coal-based production

《化学科学与工程前沿（英文）》 2022年第16卷第12期页码 1713-1725 doi: 10.1007/s11705-022-2210-y

摘要： China is the largest producer and consumer of HFC-134a (1,1,1,2-tetrafluoroethane) in the world. Coal-based route is mainly adopted to produce HFC-134a, which suffers from large waste and CO₂ emissions. Natural gas is a low-carbon and clean energy resource, and no research has been found on the environment and economy of producing HFC-134a from natural gas. In this study, CML 2001 method was used to carry out the life cycle assessment of natural gas (partial oxidation)-based and natural gas (plasma cracking)-based routes (abbreviated as gas(O)-based and gas(P)-based routes, respectively), and their environmental performances were compared with coal-based and oil-based routes. Meanwhile, considering that China is vigorously promoting the transformation of energy structure, and the application of electric heating equipment to replace fossil-based heating equipment in industrial field, which has a great impact on the environmental performance of the production processes, the authors conducted a scenario analysis. The results showed that the gas(O)-based route had the most favourable environmental benefits. However, the gas(P)-based route had the highest potential for reducing environmental burdens, and its environmental benefit was the most favourable in scenario 2050. Additionally, the economic performance of the gas(P)-based route was significantly better than that of gas(O)-based and coal-based routes.

Optimization and simultaneous heat integration design of a coal-based ethylene glycol refining process

《化学科学与工程前沿（英文）》 2023年第17卷第9期页码 1280-1288 doi: 10.1007/s11705-023-2301-4

摘要： Coal to ethylene glycol still lacks algorithm optimization achievements for distillation sequencing due to high-dimension and strong nonconvexity characteristics, although there are numerous reports on horizontal comparisons and process revamping. This scenario triggers the navigation in this paper into the simultaneous optimization of parameters and heat integration of the coal to ethylene glycol distillation scheme and double-effect superstructure by the self-adapting dynamic differential evolution algorithm. To mitigate the influence of the strong nonconvexity, a redistribution strategy is adopted that forcibly expands the population search domain by exerting external influence and then shrinks it again to judge the global optimal solution. After two redistributive operations under the parallel framework, the total annual cost and CO₂ emissions are 0.61%/1.85% better for the optimized process and 3.74%/14.84% better for the superstructure than the sequential optimization. However, the thermodynamic efficiency of sequential optimization is 11.63% and 10.34% higher than that of simultaneous optimization. This study discloses the unexpected great energy-saving potential for the coal to ethylene glycol process that has long been unknown, as well as the strong ability of the self-adapting dynamic differential evolution algorithm to optimize processes described by the high-dimensional mathematical model.

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

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.

《工程管理前沿（英文）》 2016年第3卷第4期页码 377-383 doi: 10.15302/J-FEM-2016045

摘要： Restructuring of China’s energy mix is accelerating due to factors such as energy security, economic cost, climate change and environmental pressure. Efficient and clean utilization of coal-generated power therefore plays an increasingly important role in solving energy and environmental problems in China. Coal-fired power plants, with Shenhua Guohua Sanhe as one of the pioneers, followed trend of this era and adopted multiple ultra-low emission and energy efficient technologies, striving to be an industry leader in environmental protection, profitability and innovation. As a result, coal-fired power plants have seen ultra-low emissions of air pollutants and record-high energy efficiency, opening up a new era of more efficient and cleaner coal generation. By the end of 2015, Shenhua Group had had 45 ultra-low emission coal units, providing strong support for implementing of the national policy on ultra-low emission and energy efficient retrofit of coal-fired power plants across China.

Energy conservation in China’s coal-fired power industry by installing advanced units and organized phasing

Weiliang WANG, Junfu LYU, Zheng LI, Hai ZHANG, Guangxi YUE, Weidou NI

《能源前沿（英文）》 2019年第13卷第4期页码 798-807 doi: 10.1007/s11708-019-0633-z

摘要： Coal-fired power is the main power source and the biggest contributor to energy conservation in the past several decades in China. It is generally believed that advanced technology should be counted on for energy conservation. However, a review of the decline in the national average net coal consumption rate (NCCR) of China’s coal-fired power industry along with its development over the past few decades indicates that the up-gradation of the national unit capacity structure (including installing advanced production and phasing out backward production) plays a more important role. A quantitative study on the effect of the unit capacity structure up-gradation on the decline in the national average NCCR suggests that phasing out backward production is the leading factor for the decline in the NCCR in the past decade, followed by the new installation, whose sum contributes to approximately 80% of the decline in the national average NCCR. The new installation has an effective affecting period of about 8 years, during which it would gradually decline from a relatively high value. Since the effect of phasing out backward production may remain at a certain degree given a continual action of phasing out backward capacity, it is suggested that the organized action of phasing out backward production should be insisted on.

A review on research and development of iron-based sorbents for removal of hydrogen sulfide from hotcoal gases

Jianglong YU, Liping CHANG, Fan LI, Kechang XIE

《化学科学与工程前沿（英文）》 2010年第4卷第4期页码 529-535 doi: 10.1007/s11705-010-0519-4

摘要： In poly-generation and integrated gasification-combined cycle (IGCC) systems for clean energy conversion, it is essential to remove impurities such as sulfur species from hot coal gases prior to entering the subsequent units. This paper provides a comprehensive review on previous studies on high temperature removal of hydrogen sulfide from high temperature coal gases using iron-based sorbents. A two-step desulphurization process for hot coal gas cleanup is highlighted, which is integrated with direct production of elemental sulfur during regeneration of iron-based sorbents in the primary desulphurization step. Different kinetic modeling approaches for sulfidation and regeneration were compared. Limited research on activated carbon supported sorbents was also briefly summarized.
