Gas Poisoning

Under the general policy of the national energy-saving emission reduction and sustainable development, the domestic iron and steel enterprises surge in the by-product gas power generation project. There exist many dangerous and harmful factors in by-product steel gas power generation process and which easily caused casualties and the pollution of the environment. The study on risk analysis and evaluation are still relatively dearth about the by-product gas generating process of domestic steel enterprises. The boiler system on a Combined Cycle Power Plant was analyzed and evaluation by ICI/MOND fire and explosion toxicity index method and the method of fault tree analysis, which combined with the actual situation of steel plant Combined Cycle Power Plant. The results show that the combustion system is more dangerous, and the hazard index levels are reduced to lower level after safety compensatory measures except the unit toxicity index higher. The shielding device or gas alarm failure was the main cause of gas poisoning. According to the analysis some feasible measures was put forward. The study has positive guiding significance for risk management and safety administration decision of the Combined Cycle Power Plant.

 Given increased consumer interest in green products and practices, this paper will focus on examining sustainable practices within the shipping, packaging and delivery supply chain.  “Green” shipping, packaging, and delivery focuses on transporting products from providers (e.g., manufacturers, retailers) to customers to reduce CO2 emissions, landfill waste, and overall negative impact to the environment. For example, (a) the use of electric powered vehicles in the delivery supply chain has the potential to reduce CO2 emissions; and (b) using recycled cardboard or materials that are biodegradable would reduce landfill waste. This paper examines the potential benefits of these green practices in the delivery supply chain.  Our results are that a case can be made for use of electric-power vehicles and their potential benefit to reduce CO2 emissions in an environment where power generation in non-coal based.  In other words, using electric cars in all delivery supply chains isn’t always a solution; firms must recognize the significant impact of the power generation process in their operating area.   From a packaging perspective, there is documented consumer interest on using environmentally friendly material for consumer products.  However, depending upon the market segment size, this might not always result in better financial outcomes for companies.

Operational Risks

Growing popularity of biomass power generation process is connected to its label of green and cheap renewable energy. As the second-largest producer of crude palm oil, Malaysia has abundance of biomass residues from palm oil industries and other renewable organic matters which can be converted to bio-chemicals to generate electricity. However, despite institutional arrangements, policy frameworks, funding mechanisms and incentives to support the growth of the biomass industry, there are several risks which may prone to reduce efficiency of biopower boiler especially empty fruit bunch as the fuels that cannot be ignored. Boiler is one of the primary equipment of power generation plants, in a significant role in converting biofuel to electricity. With increasing numbers of potentials of biomass as raw materials for renewable energy uses, new risks may be found. Yet there has been very little research into these risks and how to prevent them. Lack of understanding of modern risk identification methods, such as HAZOP, with the biopower industry is one of the reasons for the industry’s slow growth. An industry evolves through life cycle stages and at each stage presents risk factors such as overheating, oxygen corrosion and clinker. This paper identifies several key risks associated with EFB fired biopower boiler in Malaysia. The overview of risks not only provide a perspective from which an industry’s viability can be evaluated but also help the operators to better understand key risks and improve boiler capacity as well as plan their risk mitigation strategies more effectively.

To improve efficiency and service life of a fuel cell, it is important to understand the dynamic behavior of oxygen molecules in the cell. In other words, we need to know the oxygen concentration distribution over electrode planes and inside diffused layers in addition to its time variation. We applied the Pressure-Sensitive Paint (PSP) technique to this problem, attempting to measure distribution of partial pressure oxygen along micro channels of a fuel cell. To prevent the effect of water produced by the power generation process, we developed a water-repellent PSP that can withstand heat and humidity produced by power generation. Using this paint, partial oxygen distribution along the micro channels was successfully visualized, although there were noticeable effects of local temperature distribution on the absolute accuracy for the conditions with higher current densities.
