Firstly, analysis of the energy equilibrium among the heat evaluated from fuel consumption rate and that distributed to different parts of the main engine system was carried out, an experimental unit employing the waste heat of the cylinder jacket water was then set up on the afterdeck nearby central air conditioning room. Two adsorption towers with the same size and capacity were design in consideration of the heat and mass transfer characteristic of the water vapor within the adsorbent bed of the silica gel and that of the composite compounded with calcium chlorate. Daily amount of water produced from the extracting unit and that from desalination plant were compared in terms of the main indices prescribed by the National Standard for Drinking Water. Results show that the waste heat of the cylinder jacket cooling water under normal working condition is enough to meet the need of the heat powering the extracting unit, silica gel with pores larger than mesopore is a better adsorbent in marine environment, the composite has a better performance in water vapor adsorption, but performance in both silica gel and the composite will be weakened on board. Results also reveals that the indices of water from the extracting unit and the desalination plant are all within the permissible range prescribed by the national standard. Conclusions are drawn that the monolith of the adsorbent and the flexible connection should be used to dampen the influence from the vibration and bumping of the ship.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"91 1","pages":"1632-1636"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88997096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So we scaled up the concentrating experiment to a pilot-scale. Specifically, the cross flow velocity and volume reduction factor were optimized again for a higher flux and a lower system energy consumption. A mathematical model was established to obtain the optimal parameters. An estimation of energy and water saving effect were also developed. The optimal ultra filtration conditions obtained were: molecular weight cut-off at 10,000 Dalton, trans-membrane pressure at 3 bar, feed temperature at 50¡æ, cross-flow velocity at2 m/s, and volume reduction factor at 0.9. The average permeate flux under these conditions was 43.21 l/m2.h. The total solids content was increased from 25.47 g/l in the feed to 128.36 g/l in the concentrate. The permeate had low total solids content of 11.03g/l, Chemical Oxygen Demand of 9180 mg/l, and Biochemical Oxygen Demand of 5870 mg/l. Such qualities would allow the permeate to be reused in the APMP process after lightly biochemical treatment. With this new concentration process, about6201.7 kWh energy can be saved and 22.5 m3 effluent discharge can be reduced for each ton of pulp produced.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"27 1","pages":"2435-2438"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84425087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
