• Construction and Demonstration of a Portable Chemical Processing Unit for Purifying and Recovering Waste Gas Treating Chemicals from the Petroleum Industry
  The objective of this project was to develop and demonstrate a new technology that allows the petroleum industry to economically regenerate waste gas treating chemicals, reduce the total waste volume, and save energy required to manufacture and dispose of process chemicals. This process employs high vacuum distillation under conditions of flow and temperature to ensure that no further degradation occurs. It effectively purifies the treatment chemicals to such a level that they can be used as makeup or fresh chemicals in the gas treating process.

• Development and Application of a Multiple-batch Leaching Procedure
  Preliminary studies were conducted to determine the test conditions in a multiple-batch leaching procedure used to evaluate waste leachability. The results of applications of the multiple-batch procedure to a variety of wastes are described in this report. The leaching procedure includes six batch extractions using three different leaching media at two liquid-to-solid ratios. A wide range of leaching conditions was selected to simplify comparisons with other leaching tests and to indicate potential changes in the leachability of water under different test conditions.
