Over the past 30 years, China’s cement industry has experienced rapid development. In this study the authors estimate the emissions trend, emissions control policies, and costs of the policies in China’s cement industry under various economic growth scenarios. First, the authors develop a bottom-up energy system — multi-pollutant abatement planning (MAP) model for China’s cement industry based on the existing productivity, a set of retrofitting options and new investments, alternative fuels, and various available emission control technologies. Second, the authors identify key drivers of cement demand to develop scenarios for future cement demand (2012–2030) and corresponding output peak time under high/low economic growth conditions. Third, the authors consider three scenarios including current policies without carbon control (BAU), moderately low carbon scenario (MLC), and radically low carbon scenario (RLC). The scenarios are being built up with different emission control goals and also compared by costs with estimation of marginal abatement cost curve for cement industry. Finally, based on the estimates the authors suggest a cost-efficient green/low carbon development roadmap for China’s cement sector, considering best available technological options and policy instruments. The study estimates the benefits of co-controlling air pollutants and CO2 emissions, and proposes an innovative mechanism to deal with air pollution and climate change.

Despite a number of efforts to evaluate the utility of water-diesel emulsions (WED) in CI engine to improve its performance and reduce its emissions in search of alternative fuels to combat the higher prices and depleting resources of fossil fuels, no consistent results are available. Additionally, the noise emissions in the case of WED are not thoroughly discussed which motivated this research to analyze the performance and emission characteristics of WED. Brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) were calculated at 1600 rpm within 15%–75% of the load range. Similarly, the contents of NOx, CO, and HC, and level of noise and smoke were measured varying the percentage of water from 2% to 10% gradually for all values of loads. BTE in the case of water emulsified diesel was decreased gradually as the percentage of water increased accompanied by a gradual increase in BSFC. Thus, WED10 showed a maximum 13.08% lower value of BTE while BSFC was increased by 32.28%. However, NOx emissions (21.8%) and smoke (48%) were also reduced significantly in the case of WED10 along with an increase in the emissions of HC and CO and noise. The comparative analysis showed that the emulsified diesel can significantly reduce the emission of NOx and smoke, but it has a negative impact on the performance characteristics and HC, CO, and noise emissions which can be mitigated by trying more fuels variations such as biodiesel and using different water injection methods to decrease dependency on fossil fuels and improve the environmental impacts of CI engines.

Around 600 Mt carbon dioxide equivalents (CO2e) of anthropogenic greenhouse gases (GHG) emission originates from energy production and consumption in Indonesia annually. Of this output, 40 Mt CO2e comes from cement production. This makes the cement industry a key sector to target in Indonesia’s quest to reduce its emissions by 26% by 2020. Substantial opportunities exist for the industry to reduce emissions, mainly through clinker substitution, alternative fuels, and the modernization of kiln technologies. However, most of these abatement options are capital intensive and considered as noncore business. Due to this, the private sector is unlikely to voluntarily invest in emission reduction unless it saves money, improves revenue, enhances the strategic position of the firm, or unless governments provide incentives or force adoption through regulatory and policy controls. In this study, we review the profile of the Indonesian cement industry and assess the carbon management and climate policy actions available to reduce emissions. The case highlights opportunities for improved carbon management in emission-intensive industries in developing countries.

The use of fossil fuel is increasing drastically due to its consumption in all consumer activities. The utility of fossil fuel depleted its existence, degraded the environment and led to reduction in underground carbon resources. Hence the search for alternative fuels is paying attention for making sustainable development, energy conservation, efficiency and environmental preservation. The worldwide reduction of underground carbon resources can be substituted by the bio-fuels. The researchers around the world are finding the alternate fuel that should have the least impact on the environment degradation. This paper aims at finding an alternative for diesel and reducing the pressure on its existing demand. This study aimed at using two types of oil mixtures namely cashew nut shell oil and camphor oil mixed with diesel, turpentine oil mixed with diesel in different proportions as fuel in twin cylinder four stroke diesel engine. Performance and emission analysis have been performed by using exhaust gas analyzer in the oil samples. It was observed that 40% cashew nut shell oil and 10%camphor oil mixed with 50% diesel, 50% turpentine oil mixed with 50% diesel shows the better engine performance and also less emissions.

Performance And Emission

For economic and social development of any country energy is one of the most essential requirements. Continuously increasing price of crude petroleum fuels in the present days coupled with alarming emissions and stringent emission regulations has led to growing attention towards use of alternative fuels like vegetable oils, alcoholic and gaseous fuels for diesel engine applications. Use of such fuels can ease the burden on the economy by curtailing the fuel imports. Diesel engines are highly efficient and the main problems associated with them is their high smoke and NOx emissions.  Hence there is an urgent need to promote the use of alternative fuels in place of high speed diesel (HSD) as substitute. India has a large agriculture base that can be used as a feed stock to obtain newer fuel which is renewable and sustainable. Accordingly Uppage oil methyl ester (UOME) biodiesel was selected as an alternative fuel. Use of biodiesels in diesel engines fitted with mechanical fuel injection systems has limitation on the injector opening pressure (300 bar). CRDI system can overcome this drawback by injecting fuel at very high pressures (1500-2500 bar) and is most suitable for biodiesel fuels which are high viscous. This paper presents the performance and emission characteristics of a CRDI diesel engine fuelled with UOME biodiesel at different injection timings and injection pressures. From the experimental evidence it was revealed that UOME biodiesel yielded overall better performance with reduced emissions at retarded injection timing of -10° BTDC in CRDI mode of engine operation.

Abstract In this study, exergy, energy, performance and emission analysis were investigated for the repurpose used cooking oil (RUCO), Jatropha curcas (JC), Pongamia Pinnata (PP) and petroleum diesel fuel (PDF) fueled compression ignition engine under various engine loads. In this study, 20% of each biodiesel was tested in single cylinder, four stroke, diesel engine, given that open literature shows the potential use of biodiesel of up to 20% in a diesel engine without modification. The diesel engine was used to investigate their performance, combustion and emission characteristics of diesel-repurpose used cooking oil, Jatropha curcas, and Pongamia Pinnata fuel samples at different compression ratios and load condition. The results showed that thermal efficiency is higher with the PDF compared to DRUCO20, DJC20, DPP20 biodiesel blends. The exhaust gas temperature decreased and specific fuel consumption of the engine were increased by adding RUCO, Jatropha curcas, Pongamia Pinnata to petroleum diesel fuel. Engine ecological analysis showed that blended fuel reduces the average hydrocarbons (HC), carbon monoxide (CO) and NO X than petroleum diesel fuel. While DRUCO20 showed better performance and reduction in ecological analysis but higher ecological of CO 2 is comparable with DCJ20 and DPP20.
