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.
