Economic evaluation of reverse osmosis desalination system coupled with tidal energy

Changming LING, Yifei WANG, Chunhua MIN, Yuwen ZHANG

Frontiers in Energy 2018, Volume 12, Issue 2,   Pages 297-304 doi: 10.1007/s11708-017-0478-2

Abstract: A reverse osmosis (RO) desalination system coupled with tidal energy is proposed. The mechanical energy produced by the tidal energy through hydraulic turbine is directly used to drive the RO unit. The system performances and the water cost of the conventional and tidal energy RO systems are compared. It is found that the proposed tidal energy RO system can save water cost in the range of 31.0% 41.7% in comparison with the conventional RO system. There is an optimum feed pressure that leads to the lowest water cost. The tidal RO system can save more costs at a high feed pressure or a high water recovery rate. The optimum feed pressure of the tidal energy RO system is higher than that of the conventional RO system. The longer lifetime of the tidal energy RO system can save even more water cost. When the site development cost rate is lower than 40%, the water cost of the tidal energy RO system will be lower than that of the conventional RO system. The proposed technology will be an effective alternative desalination method in the future.

A model study on affordable steel residential housing in China

Xin CHENG, Xianzhong ZHAO, Yiyi CHEN, Zhenyu LI

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 3,   Pages 288-296 doi: 10.1007/s11709-012-0171-9

Abstract: The main research purpose of this paper is to acquire a series of designed concept of “affordable housing” in key geographical areas of East China through the development of innovative, economical, flexible, reproducible and affordable residential houses using intensive steel solutions. Toward this goal, both the residential housing conditions and the development of steel residential building in China are widely investigated. Affordable housing in China is then, based on the investigation, defined as green humanized multi-storey housing comprised of medium-small type dwellings whose construction cost is not much higher than that of traditional reinforced concrete buildings and the maintenance cost is low. Taking this definition as a guiding ideology, detailed architectural and structural design of a steel affordable housing model in terms of a collective housing form with repeatable living units has been carried out. Comparisons of project cost and energy consumption between the designed steel residential housing and the corresponding reinforced concrete building show that the former is not more expensive and consumes less energy than the latter.

Environmental and economic assessment of vegetable oil production using membrane separation and vapor

Weibin Kong, Qi Miao, Peiyong Qin, Jan Baeyens, Tianwei Tan

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 2,   Pages 166-176 doi: 10.1007/s11705-017-1616-4

Abstract: Solvent extraction of crude oil from oilseeds is widely applied for its high production capacity and low cost. In this process, solvent recovery and tail gas treatment are usually performed by adsorption, paraffin scrubbing, or even cryogenics (at low tail gas flow rates). Membrane separation, which has a lower energy consumption than these techniques, spans a broad range of admissible concentrations and flow rates, and is moreover easily combined with other techniques. Vapor recompression has potentials to reduce the heat loss in association with distillation and evaporation. In this study, we proved the possibility of combining membrane separation and vapor recompression to improve the conventional vegetable oil production, by both experiments and process simulation. Nearly 73% of energy can be saved in the process of vegetable oil extraction by the novel processing approach. By further environmental assessment, several impact categories show that the optimized process is environmentally sustainable.
