POC-scale testing of a dry triboelectrostatic separator for fine coal cleaning. First quarterly technical progress report, September 27, 1995--December 31, 1995

PDF Version Also Available for Download.

Description

The Pittsburgh Energy Technology Center (PETC) developed a triboelectrostatic separation (TES) process which is capable of removing mineral matter from coal without using water. A distinct advantage of this dry coal cleaning process is that it does not entail costly steps of dewatering which is a common problem associated with conventional fine coal cleaning processes. It is the objective of this project to conduct a series of proof-of-concept (POC) scale tests at a throughput of 200--250 kg/hr and obtain scale- up information. Prior to the POC testing, bench-scale test work will be conducted with the objective of increasing the separation ... continued below

Description

The Pittsburgh Energy Technology Center (PETC) developed a triboelectrostatic separation (TES) process which is capable of removing mineral matter from coal without using water. A distinct advantage of this dry coal cleaning process is that it does not entail costly steps of dewatering which is a common problem associated with conventional fine coal cleaning processes. It is the objective of this project to conduct a series of proof-of-concept (POC) scale tests at a throughput of 200--250 kg/hr and obtain scale- up information. Prior to the POC testing, bench-scale test work will be conducted with the objective of increasing the separation efficiency and throughput, for which changes in the basic designs for the charger and the separator may be necessary. The bench- and POC- scale test work will be carried out to evaluate various operating parameters and establish a reliable scale-up procedure. The scale-up data will be used to analyze the economic merits of the TES process. During the past quarter, a number of project tasks have been initiated. All documents required for project startup (i.e., work plans, management plans, etc.) have been submitted to DOE for approval. A bench-scale TES unit and an apparatus for studying tribocharging mechanisms have been designed and are currently being fabricated. One of the three coal samples to be used for bench-scale testing has been acquired.
