The present paper deals with the thermoeconomic analysis of a CO2 compression system using waste heat into the regenerative organic Rankine cycle. The compressor power required for CO2 compression in the Carbon Capture and Storage has been supplied from a regenerative organic Rankine cycle which is used in thermal power plant. By using the turbine power supplied from the heat drawn and waste flue gas and the intercooler heat exchangers, 8% of the CO2 separated from the waste flue gas compressed in the gas compressor. Thermoeconomic analysis of the system is performed by calculating thermodynamic and economic properties of the system. Energy and exergy efficiencies of cycle have been calculated as 17.2% and 51.6%. The average exergetic cost of waste heat flue gas as a fuel input in the integrated to the system is calculated to be 12.34 $/GJ or 947.5 $/h. The unit exergetic cost of electricity from the ORC system is calculated to be 17.47 $/GJ or 0.063 $/kWh. The unit exergetic cost of compressed CO2 gas is calculated to be 84.9 $/GJ or 184.3 $/h at 310 K and 15,244 kPa. The cost of compressed CO2 in the plant is calculated to be 18.36 $ per tonne of CO2. The total exergy destruction cost rate of the plant and the most destructive component of the flue gas heat exchanger is calculated to be 297.8 $/h and 219.1 $/h, respectively.

Wind energy is one of the renewable energy that has been widely used round the world which is abundant, renewable, and generally available. The present paper established to study the possibility of generating electric power by wind turbines for three important cities in Iraq located in terms of altitude from sea level and climate, namely (Mosul in north, Baghdad in middle and Basra in the south of Iraq). The calculations depend on the hourly meteorology data's like wind speed, wind direction and air temperature taken from (Iraqi meteorological organization and seismology) since 2005 to 2015. Noting that, the calculations had been done for three variable types of wind turbine found in global markets which differ in capacity, cutin velocity, cut-off velocity, blade diameter and initial cost. The main aims for present paper can be divide in three stages. First, it studies the possibility of using wind turbines for the selected cities. Then, it estimates the amount of annual electric power generation (EPG) and it's contribution to minimize the environmental pollution if the same power generated by gas turbine which regarded the diffuse method in Iraq. Finally, an economic analysis is also carried out for each turbine. Life cycle assessment software (SimaPro V 7.2) has been used to obtain the amount of emissions produced per kWh electricity power by gas power plant. (P1-P2) method has been used to estimate the economic data's for the project. The results of the research will decide the most appropriate zone to do the projects and the best turbine to give maximum EPG and its ability to reduce emissions with giving financial gain and payback period as an economic value to encourage the investors to apply like this project.

Environmental impact and life cycle assessment of economically optimized thermal insulation materials for different climatic region in Iraq

Environmental pollution is one of the biggest problems facing the world, even it is the most dangerous. Therefore, it becomes necessary to combine all efforts to reduce or eliminate it. Iraq is at the forefront of countries that suffer from major environmental problems. The present study aims to perform a comparative environmental assessment for three commonly available thermal insulation materials in Iraq namely expanded polystyrene (EPS), extruded polystyrene (XPS), and rock wool (RW) to select least environmental impact material. A cradle to gate life cycle assessment is performed to assess the environmental impact of each insulation material taking into account manufacturing, transportation, and installation and disposal stages. A life cycle assessment program SimaPro is used to model thermal insulation materials during its life cycle. A life cycle impact analysis method CML 2001 has been selected to assess the environmental aspects associated with two global damage categories as ozone layer depletion and global warming and two regional damage categories as acidification and eutrophication. Economically optimized amount of each insulation material is selected to represent the functional unit of life cycle assessment. The results illustrate that the EPS has the lower contribution in all environmental impact categories for all climatic regions. So, the EPS can be select as a proper thermal insulation material for the building sector from an economic and environmental perspective. The results of LCA are used to determine the amount of CO2 can be reduced per meter square of the exterior wall by using the economical amount of EPS during the lifetime of insulation material. The environmental impact results show that using EPS will contribute in CO2 emission reduction at about 81.5 % in all climatic regions in Iraq.
