DTC型采出水净化剂研究进展概述

二硫代胺基甲酸盐（DTC）是一种高效、多功能采出水净化剂，它由二硫化碳与伯胺或仲胺反应生成二硫代胺基甲酸，然后再与碱反应而制备。其作用机理是与采出水中的铁或其它溶解金属反应形成絮体，絮体迅速聚结形成网状而包裹油，从而使油去除。DTC具有净化作用快，除油功效高，适用于分离、重力沉降和浮选等水处理过程。目前，国外DTC型冷水剂已发展到第三代。

A brief introduction to the progress of DTC type decontaminant for produced water treatment

Dithiocarbamate (DTC) is a type of high-efficiency, multy-function decontaminant for produced water treatment. DTC is the product of reaction between base and dithiocarbamic acid which had been produced by the reaction of carbon bisculfide and primary amine or secondary amine. The action principle of removing oil is the net-like flocculate,which had been rapidly accumulated and formed by the reaction between DTC and iron or other dissolved metal,may envelop oil. DTC is characterized by fast cleaning treatment,high-efficiency removing oil,suitable for water treating processes such as separation,gravity sedimentation and floatation. UP to date,the third generation of DTC type decontaminant for produced water treatment overseas has been developed.
