Essays on Carbon Capture

Introduction

Carbon Capture and Sequestration (CCS) is a group of technologies that received recognition in 21 century. CCS process consists of collection and concentration of CO2 emitted from combustion of fossil fuels with further transportation to special storage locations. The reason for storing carbon dioxide away is related Greenhouse effect and its influence on global warming process. The main goal of carbon capture technologies is to stabilize the levels of greenhouse gas in the atmosphere. It is expected that implementation of CCS technologies will make it possible to reduce the total emission of CO2 up to 54% (to 450 ppmv). ( ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Introduction

Coal is a very cheap and abundant provision of energ. In fact, it is the most abundant fuel in the United States; U.S. has the highest coal reserve in the world, with up to 25% of the known world coal present in America and being mined in 26 out of the U.S. 50 states (fe.doe.gov, 2013). However, this abundant energy is seldom used because it is a very dirty energy. According to Hong & Slatick (1994), up to 204.3 pounds of carbon dioxide per million Btu is emitted when coal having 78% carbon content is completely burned to attain a ...

Abstract

The concentration of carbon dioxide has been abnormally increasing over the years. In the year 2016, its concentration exceeded the limitations, and has been considered as a dangerous situation. As a response to the increasing carbon dioxide content in the Earth’s atmosphere, different processes are being suggested in order to lower the concentration. Carbon Capture and Storage, or CCS, is one of these processes. Generally, there are three different phases of this process: the pre-combustion, the oxyfuel, and the post-combustion. These three phases have different processes in which the carbon dioxide content is being separated from the other ...

Abstract

Carbon Capture and Storage Technologies (CCS) is a technological method that is used to reduce the emission of carbon dioxide into the atmosphere from a variety of sources including industries and fossil fuels production and power sources. This type of technology involves the capture of dioxide either after burning or before burning and then transporting via ships or pipelines and then directing it into the deep underground for storage purposes. This type of technology has been in existence since the 1970’s and has rapidly evolved over time. In fact, the increased impact of the greenhouse effect due to increased amounts ...

Introduction

Global warming and pollution has led companies to rethink their activities concerning green methods of production. Carbon dioxide emissions are the leading cause of global warming and the dangers of global warming have been documented for a long time. Governments have come up with restrictions on emissions, which have forced companies to re-think the way they do production. Quest carbon capture and storage project is one example of how companies are re-thinking their strategy and practice towards carbon emissions. This project is developed by Shell for its Athabasca oil sands project (AOSP) in Alberta. It is the first carbon capture ...

Carbon Capture Technologies

Introduction Aside from oil, coal is regarded as one of the most important fossil fuel resources being utilized in the global energy mix. However, the use of coal in power generation has resulted in serious air pollution around the world. The use of coal has resulted in the release of almost 14 billion tons of carbon dioxide into the atmosphere, with a majority of these pollutants emanating from power generation activities. Carbon dioxide sequestration technologies seek to address the release of carbon dioxide into the atmosphere that add to the growing problem of ...

Global Warming: Cause and Mitigation

Global Warming: Cause and Mitigation Global warming is the change in the climate due to the rise in the temperature of the earth’s atmosphere and the oceans. Ocean and climate are linked to each other and so oceans bear the effect of climate change as evidence by increase in the sea level and change in the temperature. This rise in the temperature of the earth’s surface caused increased global warming of the climate. This change in the climate in turn impacts the health of marine species, ecosystem and also humans. Similarly the greenhouse gases produced by ...

Introduction

Carbon dioxide is the main byproduct in a brewery. Accordingly, we have identified source of carbon dioxide, as an exhaust gas produced in a brewery. This report explains how such a source of carbon dioxide can be harnessed for future use.

Air extraction technology to capture atmospheric carbon dioxide

We understand that due to excessive burning of fossil fuels there is abundance or more than expected amounts of carbon dioxide in the atmosphere. Accordingly, carbon dioxide can be extracted from atmospheric conditions using various technologies. This technology of carbon dioxide capture is a step wise process, which is called air extraction (Zeman and Lackner, 2004). In this technology, the ambient air ...

Retrieved October 1, 2013, from http://pubs.acs.org/doi/abs/10.1021/ie049962v Power plants are usually advised to apply Carbon dioxide capture in the final storage as an alleviation option to climate changes. Various carbon dioxide captures concepts apply sorption and desorption cycle as a method of separating Carbon dioxide from flue gas as well as oxygen from air. However, it is required that all carbon capturing processes must be in a position to handle the massive flow of carbon ...
