Carbon Dioxide Capture from PowerPlant Flue Gas using Activated Carbon ab 49 EURO Efficient Low Utility Cost and Energy Conservative Technology to Chemically Adsorb Carbon Dioxide from Flue Gas
Single stage absorption chillers (water/lithium bromide) can operate using low grade heat, thus single stage absorption chillers can operate using low temperature geothermal resources. An EES computer model was written for the single stage absorption chiller based on overall heat transfer coefficients, mass flows, salt balances, energy balances and other assumptions. The single stage model was calibrated with well known and available data from US and Japanese manufacturer. The system was considered to work in hot and humid climate like Abu Dhabi and Shanghai. The results show that in the case when cooling water is 28°C hot the initial and annual total cost is high. However, as cooling water temperature decreases the initial and annual total cost decreases sharply (when cooling water is at 20°C the reduction is around 35% of total annual cost). The results show great influence of cold and hot water on the performance and total annual cost of absorption chiller. A second part of a computer model contains a Total Equivalent Warming Impact (TEWI) analysis. TEWI considers both, the direct refrigerant effect and the primary energy impact on the equivalent carbon dioxide (CO2) emission.
Carbon credits are a key component of national and international attempts to mitigate the growth in concentrations of greenhouse gases (GHGs). One Carbon Credit is equal to one ton of Carbon. Carbon trading is an application of an emissions trading approach. Greenhouse gas emissions are capped and then markets are used to allocate the emissions among the group of regulated sources. The idea is to allow market mechanisms to drive industrial and commercial processes in the direction of low emissions or less "carbon intensive" approaches than are used when there is no cost to emitting carbon dioxide and other GHGs into the atmosphere. Since GHG mitigation projects generate credits, this approach can be used to finance carbon reduction schemes between trading partners and around the world. There are also many companies that sell carbon credits to commercial and individual customers who are interested in lowering their carbon footprint on a voluntary basis. These carbon offsetters purchase the credits from an investment fund or a carbon development company that has aggregated the credits from individual projects.
Agricultural soils represent a potentially significant low cost sink for carbon dioxide with multiple potential co-benefits to farm productivity and profitability.Since agricultural soils can store more carbon, a modest increase in carbon stocks across the large land areas used for agriculture would represent a significant GHG mitigation. Sugarcane accompanied with good farming practices has the potential to sequester considerable amounts of carbon and so contribute to climate change mitigation.
The power sector is experiencing profound changes worldwide as policies are enacted to address the linkages between energy use and environmental degradation, energy security, and economic development. This research examines the interactions between a carbon dioxide (CO2) cap and a renewable energy quota, using the United Kingdom s power sector as a case study. Simulation scenarios show that energy efficiency underpins the success of both programs. Energy efficiency investments can eliminate the need for new nuclear plants and make compliance with the CO2 cap significantly cheaper. With higher fossil fuel prices, there is limited interaction between the two programs as the CO2 cap swamps the renewables target because renewables are favored in the least cost solution. The renewables quota must be included in the regulatory mix under periods of low fossil fuel prices otherwise firms will switch from coal to gas generation. The modelling shows that both programs are required in order to deploy renewables as well as reduce CO2 emissions across a wide range of market and policy outcomes. The programs need to be jointly administered to reduce duplicative costs to industry.
Nanotechnology is one of the extensively high advanced technologies of the world and emerging in haste with its entire span and has a diversified use. Titanium dioxide (TiO2) has been extensively studied as a photocatalyst in nanotechnology for different applications such as water and air remedy, because of its relatively high photocatalytic activity, robust chemical stability, relatively low production costs, and non toxicity. Nano-structured TiO2 was synthesized using sol-gel method with and without presence of nano porous polymer . Photocatalytic efficiency of the samples have been characterized by several techniques (SEM, EDS, UV Spectroscopy and XRD). This photocatalytic process might be effective to remove this color and minimize the cost of an effluent treatment plant.
Construction sector plays a major role in affecting environment due to heavy energy consumption and emission of carbon-dioxide gases from machines during manufacture of conventional building materials. Adapting energy efficient technologies can reduce the emissions from co2. Even though there are many building materials available in the market for constructing low rise building, author has investigated on mud as sustainable alternative building material for conventional building materials. Mud has crucial factors for sustainable construction practices and effective reduction in mitigating global warming. The cost effective construction technologies would emerge as the most acceptable case of sustainable technologies in India both in terms of cost and environment.
Over the years, a revolution in the Means of Transportation has exploded and developed from the Era of Camels and horses to the invention of the internal combustion Engine and the Diesel Engine, so there were a new source of energy was used which is Petroleum to run these engines, but in the Last 10 Years the cost of the Petroleum has increased rapidly by the Major Growth In the Universal population and the increase in the amount of moving cars per day, also there is A Major Problem that is facing the world this is the air pollution that is produced from the Crude oil Production and Ignition which evacuate Harmful gases as Carbon Dioxide and toxic As Carbon monoxide that affects human health, so a new Source of energy must substitute the Petro diesel which is Biodiesel which is clean, renewable fuel Biodegradable and non-toxic and Produce low emissions comparing with Petroleum Diesel which cause a lot of pollution.
