Although the DOE-furnished data acquisition was not fully automated and bugs remained in the program, the system was operated and the data were compared with that obtained by Paraho data processing. On-stream analyses were not operational during the computer operation. The Hewlett-Packard (HP) gas chromatograph had provided valid data earlier. Maintenance and repairs of subsequent malfunctions by DEI, HP, and LETC personnel failed to provide valid on-stream GC analyses. The software program and options, controlled by LETC, could not be completely debugged during the short operating period. Routines, devised by DEI, were established to circumvent the program bugs and to obtain valid data. Data were obtained for fifteen 24-hour test days during June-July, 1978 and compared with Paraho's. Air and gas flows compared within 1 the accuracy of measurement. Total carbon and weight balances generally agreed within to 2%. Results from these comparisons show that both systems - the DOE-furnished data acquisition and Paraho data processing - do provide valid data.
