Essays on Coal Combustion

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). ( ...

Introduction

Waste is generated as a result of a lot of physical, chemical, and biological processes. Dumping it at some appropriate place is one option. However, ecological effects of throwing away waste products are becoming a serious concern these days. In order to minimize waste, the best strategy is to transform it into valuable products . Plenty of research studies have been carried out to utilize waste effectively. The aim of this report is analysis of the proposed methods for the utilization of common forms of wastes for useful purposes. We also recommend better alternatives to help create a lesser negative ...

Abstract

The most widely used fossil fuel around the world is coal. This is a component that carries both organic and inorganic components and hence its combustion over the years has led to environmental problems such as acid rain and sulfur dioxide emission. To combat this eco-system problem several combustion methods have been introduced and one of the most efficient means that has come to the attention over the years as a significant way is the Oxy alkalinolysis. In the past, there have been various desulfurization processes, which have been introduced. However, most of them have not given excellent results are ...
