Because it is a cleaner fuel than oil or coal and not as controversial as nuclear power, gas is expected to be the fuel of choice for many countries in the future. Positive contribution of NG on environmental pollution must also be considered in economical aspects. NG is widely available. CO 2 emission of NG is lower than both diesel fuel and gasoline, which makes NG engines favorable also in terms of the greenhouse effect. The correlation equations for production and consumption trends of natural gas (VNG) versus year (Y) are:","PeriodicalId":11841,"journal":{"name":"Energy Sources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84187353","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}

The pyrolysis characteristics of the samples were analyzed using TG/DTG curves. Differential thermogravimetric data were analyzed by a model assuming first order kinetics.

It was observed that lignite, which is commonly used for heating in Turkey, is a significant component of SO 2 and PM formation. Variation of SO 2 and PM data in the city centers that consume natural gas was compared with the data of some city centers that do not consume natural gas. It was observed that SO 2 and PM averages of the city centers that started to consume natural gas have regularly diminished.","PeriodicalId":11841,"journal":{"name":"Energy Sources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78986305","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}

The measurement methods are compared within the context of reservoir wettability. It is suggested that for reservoirs with predominant water-wetness, unsteady-state experiments could be run under the suggested Peters and Khataniar (1987) stability criteria. Steady-state experiments could also be run for comparative and in turn quality control purposes. In addition, a combination of unsteady-, steady-state and centrifugal experiments could be adopted to generate trustful results for reservoirs with intermediate wettability, but only if one has a reliable initial relative permeability to oil (k ro ) at a representative initial water saturation (S wi ). As such, it is recommended to use an unsteady-state technique for the initiation of the displacement experiments, a steady-state method for mid-range saturations, and the centrifuge for tail-end saturations. It should be noted that for the centrifugal method, comparable centrifugal and viscous forces are required to mimic displacement processes. Coyne's procedure could also be used for comparative and quality control purposes.","PeriodicalId":11841,"journal":{"name":"Energy Sources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81918144","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}
