Solvent refining of Indiana V coal and North Dakota lignite. Final report
High Sulfur Indiana V coal was solvent refined in a bench scale unit to determine operating conditions necessary to produce low ash product with less than 0.9 wt% S. Necessary background information was generated prior to recommending further processing of this coal at the Wilsonville SRC pilot plant. North Dakota lignite was processed in the same unit to determine its suitability for further study at the pilot plant level. Three sets of operating conditions utilizing three different mixtures of carbon monoxide and hydrogen were evaluated. On the basis of these results, further testing of lignite at Wilsonville was deferred. The report summarizes operability information and product distribution data, hydrogen, carbon monoxide and water consumption, as well as elemental analyses of products and product fractions.
This article introduces the general situation of Beijing-Tianjin Products Pipeline,analyzes the influence of solid matter on products quality and the necessity to pig the pipeline. The authors describe the pigging practice of the pipeline and put forward suggestions in pigging operation.
