Glass Technology

Finland has formed a unique energy saving and emission reduction concept in the process of realizing the leap from agriculture to industrialization, which has been shown in the utilization of raw materials, optimizing fuel structure, recovering waste heat and waste disposal. These concepts and aspects have been widely used in the glass industry, from the early glass technology reform to the present stage of technological innovation for the development of Finnish glass industry to provide an important guarantee. Finland experience provides experience and reference for the development of glass industry in China, which has important strategic significance in the increasingly severe environment of energy crisis.

In this paper, a detailed description of a project designed to recovery and utilize waste heat in a cotton manufacturing enterprise in Shandong, Jin Mao Textile Co., Ltd(China) is presented: both energy saving and emission reduction(ESER) aspects have been thoroughly considered. First of all, an accurate analysis of the status of the previous cotton mill for production process was developed, to identify possible improvement opportunities; then an energy saving reformation of waste heat recovery in cotton mill was proposed and designed. After that, by means of a comprehensive feasibility analysis, the ESER indices were calculated assuring good environmental benefits of the plant modification investment. The modifications to the system make it possible to achieve consistent annual savings of coal, electricity and waste heat, CO2, SO2 emissions through effective recovery and utilization of the waste heat that was discharged into the atmosphere in the original production. Implementation of the reformation system fulfilled the waste heat recovery and utilization. And also create good environmental benefits.

Carbon Emission Reduction

The carbon emission and energy consumption of using slag as a secondary raw material in cement production was quantified and analyzed in this study. Moreover, the carbon emission reduction and energy saving potential of slag-based cement (SBC) production were identified based on the comparative analysis between SBC and traditional Portland cement (TPC). The results showed that the carbon emission of SBC is about 6.73%, which was lower than that of TPC. Compared with TPC, the energy consumption of SBC is slightly increased by 2.05%. In addition, it was found that the combustion of coal and the power generation were the main sources for carbon emission in the life cycle of slag utilization, which account for 83.39% and 10.16% of the total carbon emission. Therefore, reducing the consumption of energy and increasing the recovery rate of waste heat in cement production were the most effective methods to improve the environmental performance of SBC. In addition, the improvement potential analysis was carried out for SBC. The results indicated that if the recovery rate of waste heat could reach to that of the international advanced level (15.6%), the carbon emission and energy consumption of SBC would be reduced by about 2.20% and 5.71%, respectively. If the proportion of renewable energy utilizationin power generation increased to that of the average international level, the carbon emission and energy consumption of SBC would be declined by 5.26% and 9.35% respectively.

This paper studied the preparation of chemical raw materials–methanol using blast furnace gas obtained from steel production process. The energy saving and emission reduction effect and the economic benefit brought by the co-hydrogenation process of a mixture of CO and CO2 (CHP) has been compared with those brought by the respective hydrogenation process of CO and CO2 (RHP). The result shows that the CHP brings more economic benefit than the RHP, and the CHP brings more energy saving and emission reduction effect than the RHP.

The urban heating is closely linked with peoples life. The chosen of heating scheme is affected by the index of energy-saving and emission-reduction. In this thesis the computational model of the indexes for different range were built and the indexes of four schemes were calculated. The results predicted the energy-saving and emission-reduction of each scheme and provided references for the government to formulate assessment criteria.
