  • Life cycle costing of a self-sufficient solar-hydrogen system

    In a renewable energy-based system, energy storage must match the energy demand with supply. Usually a lead-acid battery is utilised as a short-term energy buffer. A system, which has a combination of an electrolyser and a high-pressure hydrogen tank for long-term energy storage, is considered in this paper. The cost intensive components are sized considering the least cost and by performing a ...

  • Aerating recycled water on mushroom composting sites affects its chemical analysis and the characteristics of odor emissions

    Recycled water (RW) containing compost leachate can be a potent source of foul odor on mushroom composting sites. Samples of RW were repeatedly collected from storage tanks and pits of 14 mushroom composting sites in England and Ireland. Relationships between the effects of submerged aeration of the RW, the chemical and microbial characteristics of the RW, and the odors emitted were investigated. ...

  • Chemical Industry: Sale of by-Product HCl Covers Cost of Emission Control System Problem Case Study

    Some of the specialty chemical processes at a major chemical manufacturer’s plant result in considerable HCl loading in the off-gas.
