This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes. rank coal characteristics, which influence the design and the performance of the process, rendering these coals good gasification feedstocks and in most cases better overall than bituminous coals. Gasification processes and technologies, the main topics of this chapter, are treated in more detail.
All coal gasification-based conversion processes require removal of hydrogen sulfide (H 2 S; an acid gas) from the syngas as part of the overall plant configuration. Typical acid gas removal (AGR) processes employed for gasification design are either a chemical solvent system (e.g., amine gas treating systems based on MDEA, for example) or a physical solvent system (e.g., Rectisol or Selexol). The basis of the environmental assessment will be: 1) the published literature on gasification processes and related control technologies; 2) data which are being generated by other EPA contractors working in related areas (e.g., low/ medium Btu gasification environmental assessment; coal liquefaction environ- mental assessment, etc.); 3) data.
Experimental systems. As reported in IARC Monograph Volume 34 (), coal-gasification samples from the process stream and waste by-products were found to be mutagenic in various strains of Salmonella typhimurium in the presence of an exogenous metabolic activation system. The mutagenicity was found primarily in the fractions containing polycyclic aromatic hydrocarbons and their alkylated. Gasification processes that use hydrogen fuel cells on site can substantially increase their efficiency compared with traditional coal-fired power. However, depending on the end-use of the.

This evaluation provides estimates of performance and cost data for advanced technology, high-Btu, coal gasification facilities. The six processes discussed reflect the current state-of-the-art development.
Because no large commercial gasification plants have yet been built in the United States, the information presented here is based only on pilot-plant by: 6.
The coal gasification processes, including aspects of technical procedure and economic factors, are outlined. Topics of discussion include coal High-Btu coal gasification processes book chemistry, low and medium Btu gasification processes, and high Btu gasification processes.
Information is also included on solar gasification processes and pollution control techniques. Get this from a library. High-Btu coal gasification processes.
[Christopher F Blazek; Nathaniel R Baker; Raymond R Tison; Institute of Gas Technology.; Argonne National Laboratory.]. The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes.
The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are. This book provides an excellent overview of current technologies for the gasification of coal, oil, gas, biomass and waste feedstocks.
Starting from the basic theory, it reviews the potential feedstocks and their suitability for different types of gasification Edition: 1. Book chapterFull text access. Chapter 2 - Non-gasification Uses of Coal Pages Publisher Summary Coal is used primarily as a fuel for large industrial boilers, especially for electric power generation.
The most common type of coal-fired power plant is pulverized coal combustion (PCC). So, this section will cover emissions and controls for coal conversion processes on a qualitative level only. Gasification - All of the major operations associated with low- medium- and high-Btu gasification technology (coal pretreatment, gasification, raw gas cleaning, and gas beneficiation) can produce potentially hazardous air.
An Eulerian-Eulerian computational fluid dynamics (CFD) model of the gasification processes in a coal bubbling fluidized bed (BFB) is presented based on the experimental setup taken from the literature.
The base model is modified to account for different parameter changes in the model setup. The exiting gas compositions for the base model have been averaged over time and validated with Cited by: Process to make high-BTU gas from coal.

Bureau of Mines. Coal Gasification Program. This book provides an excellent overview of current technologies for the gasification of coal, oil, gas, biomass and waste feedstocks.
Starting from the basic theory, it reviews the potential feedstocks and their suitability for different types of gasification process. Commercial and near-commercial processes are described individually and various features discussed in detail.5/5(2).
Gasification is a key technology in converting coal, biomass, and wastes to useful high-value products. Until renewable energy can provide affordable energy hopefully by the yeargasification can bridge the transition period by providing the clean liquid fuels, gas, and chemicals from the Cited by: 2.
Each of three types of coal gasification processes is presented in a separate section of the recommended standard, distinguished not only by operating process and technology but also by the nature and extent of potential exposures: (1) high-BTU product co,al gasification, (2) coal gasification (low- or medium-BTU product)File Size: 4MB.
Carbon gasification reactions form the basis of many important industrial processes, such as the combustion of coal and the produc tion of synthesis gas, fuel gases and activated carbons.
They are also involved in metallurgical processes and in the regeneration of coked catalysts. Thus. This chapter deals with coal gasification, which is a process that converts carbonaceous materials, such as coal, petroleum, petroleum coke, or biomass, into carbon monoxide and hydrogen. Coal gasification as a power-generation technology is gaining popularity due to the ready global availability of the raw material (coal), as well as positive environmental issues associated with this technology.

Hasan Reza. A process for the manufacture of high-btu gas from coal has been developed by the Bureau of Mines. The process consists of fluid-bed gasification of the coal, followed by the gas treatment steps of gas purification and methanation.
This book addresses the science and technology of the gasification process and the production of electricity, synthetic fuels and other useful chemicals. Pursuing a holistic approach, it covers the fundamentals of gasification and its various applications. Carbon gasification reactions form the basis of many important industrial processes, such as the combustion of coal and the produc tion of synthesis gas, fuel gases and activated carbons.
They are also involved in metallurgical processes and in the regeneration of coked catalysts. The use of coal is required to help satisfy the world's energy needs. Yet coal is a difficult fossil fuel to consume efficiently and cleanly.
We believe that its clean and efficient use can be increased through improved technology based on a thorough understanding of fundamental physical and chemical processes that occur during by: It was assumed that the gasification process would be carried out in a gasification reactor with t/h of raw coal processing capacity.
