Abstract

The large amount of CO 2 that can be mitigated by geologic storage had gained interest during the last 15 years. Acceptance of CCS under CDM is still under discussion(IEA, 2008) however there are several pilot or field scale projects and monitoring surveys that are underway which will make the technology better known and resolve the risks involved. This study involves assessment of possible geologic sites for CO 2 storage and calculation of CO 2 emissions from thermal power plants with capacities "500 MWe, cement factories, steel industry, sugar factories and refineries in Turkey. In emission calculations IPCC methodology is used. Coupling of sources and sinks resulted in a decision to use the emissions from a cement factory which is about 130 km from the selected oil field, Caylarbasi. The cement factory does not have capture facilities yet, but during modelling it was assumed that CO 2 is available at the factory site. According to the results of the model study, during the project life of 20 years, enhanced oil recovery effect of CO 2 lasts 8 years and 2 million barrels of oil will be produced and the remaining 12 years are modelled as CO 2 storage phase which shows 220 million Sm 3 of CO 2 can be stored.The transportation phase was designed with two alternatives, pipeline transport and transport by tankers. Economic evaluation at 100$/barrel of oil value, it will be possible to produce for 6 years. For the following years during CO 2 storage, incentives are necessary to cover operating costs so that project will continue for 20 years. Since the initial investment is already made, only the operational costs must be financed. Natural CO 2 field in Dodan is another possibility for geologic storage, the field has already produced 7 billion Sm 3 of CO 2 for the BatiRaman EOR project. Total capacity is about 10 billion Sm 3 . Other possible storage sites are deep saline aquifers, which were encountered in Thrace region, Central Anatolia and South Eastern Turkey and salt caverns of the soda mines. The experience of the Turkish oil industry for use of CO 2 in EOR application in BatiRaman field will be utilized if and when such an application is required.

Abstract

Timber residues due to its use for the construction industry and others provided by the secondary forest and its high content of lignocellulosic material for energy purposes, our objective was to evaluate the forest residues of six species to obtain carbon as clean energy. , which represents great interest for the energy industry. Through the methodology of the study of inventories and sampling of wood residues from sawmills that was in the four cantons of the province of Pastaza, through instrumental techniques of physical, chemical and thermal analysis, the parameters studied were the biomass potential and residue, density, humidity, ashes, volatiles, fixed carbon and higher calorific value (immediate analysis), carbon, hydrogen, oxygen, nitrogen and sulfur (CHONS), which allowed obtaining the thermochemical properties, reaching the main results of energy potential, of these three species that can be used for clean energy, due to the amount of ash found in the analyzes below 1% and volatiles (60-80%) of these residues, which clearly shows that it prevents the formation of scale in equipment and damage, in relation to its fixed carbon content on average of 14.78% and its superior calorific value 19.72 Mj/kg, assessing the fact industrial reliability for its energy use that will generate 515.62 GW of clean energy in electrical thermal power annually to meet the needs of vulnerable areas of the Amazon region.
