Green Evaluation Of Water Treatment Chemicals In Oil Field

Based on the state-of-art review of green design and evaluation method, an integrated evaluation method is proposed for water treatment chemicals according to their green degrees (environmental properties) and treatment performances, and is used to evaluate water treatment chemicals in Daqing Oil Field.The water treatment chemicals investigated in this work include flocculating agent, germicide, corrosion inhibitor and scale inhibitor. The green properties of water treatment chemicals are determined according to pollution resulted from their uses in oil field and their production processes, while their treatment performences are done from the experimental effects in oil field. The evaluation results are given for flocculating agents, germicides, corrosion inhibitors and scale inhibitors used in Daqing Oil Field.The integrated evaluation method can guide the production processes of water treatment chemicals, and is also helpful to evaluate other chemicals in oil field.
