Moreover, the interdependent operating conditions like reactor temperature, moisture content of biomass, and air fuel ratio play a major role in the composition as well as calorific value of syngas. The gasification of oil-palm fronds (OPF) is not studied in the past, and there is no previous work on the expected composition or CV of syngas. Therefore, it is found necessary to predict the CV of syngas for different operating conditions, in order to be able to exploit the energy reserve of this abundantly available biomass waste. This paper presents the prediction of CV of syngas produced from downdraft gasification of OPF by making use of ASPEN PLUS simulation model. The results of the simulation showed how the CV varies with operating conditions: moisture content, air fuel ratio and oxidation zone temperature. The result of the model showed that the CV predicted vary in the range of 4.05 to 4.35 MJ/m3 for increase in the oxidation zone temperature from 500 to 1200°C. In addition, the CV showed a decrease with moisture content. Moreover, a closely similar pattern of change in CV is obtained, through comparison with results reported in literature for gasification of other types of biomass feedstock.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85438627","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}

High oil prices and dropping reserves alternative has inspired interest in chemical flooding technologies, particularly for application in mature water flooding. The more concern about this technique is surfactant development. A new sulfonate surfactant from non-edible vegetable oils is developed as an alternative source of petrochemical feedstock which is not desirable due to the environmental problems and high cost. The sulfonate surfactant was synthesized from C16–18 feedstock and evaluated in phase behavior, IFT for its capability to enhance oil recovery. The feedstock is composed mostly of unsaturated fatty acid derived from jatropha curcas oil which can be converted to fatty acid methyl ester. The methyl ester is epoxidized and hydrolyzed to hydroxyl groups, which subsequently were sulfonated to form a product named Methyl Ester Sulfonates (MES) or α-sulfonated methyl esters. The phase behavior between crude oil (37.7 deg API) and surfactant solution show the ability of the surfactant to create clear microemulsion free of gel, liquid crystals, and macroemulsiuon and also rapid equilibration to low-viscosity emulsion. Based on IFT experiments optimum surfactant concentration determine as 2500 ppm which result in a lowest possible IFT around 0.078 mN/m in presence of Na2CO3 as alkali. The results illustrate the possibility of developing new surfactants from vegetable oils which can obviate the need for using petrochemicals substances.","PeriodicalId":6411,"journal":{"name":"2011 National Postgraduate Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77364051","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}

However, there is need of solving the problem of interoperability due to everyday increase of data from different sources. Whereby, the resourceful information or data integration between human and machines are needed. Thus, more precisely, this paper addresses an ultimate problem of integrating and utilizing the accurate data on information systems. The proposed methodology of this paper includes: (1) grounded theory that focuses on particular interaction between human and machines, (2) developing the analysis; the research introduces the Software Development Life Cycle (SDLC) approach, from the development to implementation stages, (3) sources of data; for state-of-the-art research, we propose to use MetOcean (Meteorological and Oceanographic) data, and (4) Research instrument which is to set our research into practice where we will build Semantic Web application using Franz AllegroGraph and use SIMILE (Semantic Interoperability of Metadata and Information in Unlike Environments).
