Oil/Gas Complex Conceptual Design/Economic Analysis:Oil and Sng Production. R and D Report No. 114,Interim Report No. 4.

摘要

Results are presented of a conceptual design and economic evaluation for a commercial complex to mine high-sulfur coal and produce substitute natural gas (SNG),fuel oil,naphtha,and liquefied petroleum gases (LPG) using hydroliquefaction technology for the coal conversion portion of the complex. The design uses the solvent refined coal (SRC) hydroliquefaction and entrained slagging gasification programs,with adaptation to the specific Oil/Gas objectives. Pseudo catalytic SRC II hydroliquefaction techniques are used in which a portion of the hydroliquefier effluent is recycled to the hydroliquefier reactor to provide a higher content of ash constituents,longer reaction time,and greater hydrogen consumption to produce products that are primarily gases and liquids at ambient conditions. The design basis was developed in cooperation with ERDA. Process flowsheets and heat and material balances are presented. (ERA citation 02:053620)
