Explanation
Average measured billing difference per car over three month* ia 1. 000 lbs/car (0.57%). Connoco has short-shipped and are allowed 1% difference
under contract.
Based on actual weight of reactor cleanings in plant*
Based on Lab analysis of effluent streams. Based on weights of material moved to dump from plant.
Based on sample analyses from exhaust. Based on average solids removed from trap. Based on analysis of wash water streams. Based on plant experience October through December,
1973.
Based on flow rates and Lab analysis of vent stream. Calculated from free VCl analysis of slurry.
Based on flow rates and Lab analysis of vent stream. Calculated based on volume and average vacuum of 21" Based on Lab analysis of stream.
Based on Lab analysis ox dry resin.
Based on Lab analysis of effluent.
Reflects leaks, pump priming and inaccuracies in sampling various vent points. Program has been set up to continue analytical work and obtain better data for balance.
