COAL AND GAS PIPELINE FEASIBILITY STUDY VOLUME II TECHNICAL & ECONOMIC EVALUATION

摘要

This study concerns three sequential coal processing operations:beneficiation, gasification, and transportation. In the final step, clean coal is transported pneumatically by means of a fuel gas stream produced during gasification. The three processes are a means of providing clean, reasonably priced fuels to the major demand areas of the United States.nThree benefication techniques were considered, dry air table cleaning, wet deep cleaning through heavy media cyclone and floatation cell systems, and a conceptual air classification/screening system.
