The Wilsonville SRC pilot plant operated 511 hours, or was on-stream 69 percent of the time during August. The distillation section operated an additional 58 hr. All operational time was used to process Indiana V coal from the Old Ben No. 1 Mine. A material balance was in progress at the start of the month. This was completed on 1 August. To obtain short residence time data and product samples, the dissolver was bypassed starting 3 August. The bypass run was terminated because of mechanical problems on 4 August after samples were obtained. A period of operations to produce SRC with a lower sulfur content was completed on 21 August. The sulfur in the SRC was in the range of 0.7 percent. Both the Sharples and the Dorr-Oliver centrifuges were operated in series, with the Sharples underflow filtered in the Funda filter. Both machines operated satisfactorily for a period of 75 hr. The Sharples centrifuge reduced the solids content of the overflow to the expected level. Specification SRC was not obtained from the Dorr-Oliver centrifuge. It is believed that operation at about 525/sup 0/F would improve the performance of the Dorr-Oliver machine. An examination of the upper part of the dissolver was made by Oak Ridge personnel. No evidence of cracking or corrosion was found.
