摘要

国内新开发的一些含汞气田中天然气汞含量较高，进而天然气生产过程中产生的气田污泥中汞含量也偏高，且含汞气田存在大量堕需处理的含汞污泥。结合气田含汞污泥的特点，在国内率先开展气田含汞污泥处理工艺技术的研究，这对我国含汞气田的可持续发展、环境保护及操作人员安全具有指导作用。常用的含汞污泥处理工艺主要有热处理工艺、固化或稳定化处理工艺等。本文基于常用污泥处理工艺的分析和气田污泥特性，提出了气田含汞污泥热处理方案，主体采用热处理工艺，所提出的含汞污泥热处理方案具有污泥处理彻底化、无害化、高能量利用率、低能量损失产生和汞回收率高等特点。本范文的研究成果有利于有效控制气田污泥汞污染问题，可根据气田实际情况建立含汞污泥热处理方案的现场试验装置，具有一定的工程应用价值。

Heat treatment technology of mercury containing sludge

Abstract

The mercury content of Tanaka gas in the newly developed gas is higher, and the mercury content in the gas field produced in the process of natural gas production is also high. According to the characteristics of gas mercury containing sludge, the first in China to carry out field study on the technology of sludge treatment of mercury, which plays a guiding role in the sustainable development of our country, mercury gas environmental protection and safe operation. The commonly used mercury containing sludge treatment process is mainly heat treatment process, solidification / stabilization treatment process, etc.. This paper used sludge treatment technology analysis and put forward based on the characteristics of sludge gas field, gas mercury containing sludge heat treatment scheme, main use of heat treatment, heat treatment of mercury containing sludge pmix sludge treatment completely harmless, high utilization rate, low energy loss and high energy recovery of mercury. The research results of this paper can be used to effectively control the mercury pollution of the gas field sludge, and it can be used as a field test device for the heat treatment of mercury containing sludge.
