Problems solved by technology

During flue gas oil recovery, dust removal, desulfurization, and denitrification must be carried out on the flue gas. This is a very complicated process. At present, the equipment used in on-site industrial applications and production implementation is too large, and the processing process is relatively complicated, which cannot meet the requirements. oilfield production needs
In particular, the currently used flue gas treatment devices do not treat NO X process, NO X and SO 2 When it meets water, it forms strong acid, which severely corrodes surface pipelines, equipment and downhole tubing, thus limiting the development and application of flue gas recovery

Abstract

The present invention relates to the utilization of fume in triple oil production in oil field. The fume desulfurizing and denitrifying dedust apparatus consists of blower, wind cooler, gas-liquid mixer, circulating pump and circulating tank connected together. The fume desulfurizing and denitrifying dedust method includes blowing the fume from steam boiler to the wind cooler for cooling, mixing the cooled fume with sodium carbonate solution the circulating pump pumps inside the gas-liquid mixer, and further absorbing with the treating liquid in the circulating tank. The apparatus of the present invention has compact structure, simple installation and operation, low cost, and high desulfurizing, denitrifying and dedusting efficiency.

Description

Technical field: [0001] The invention relates to a ground device and method used in oil field tertiary oil recovery technology and production process. Background technique: [0002] As oilfield development enters the middle and later stages, crude oil extraction is becoming more and more difficult, including CO 2 Drive, N 2 The application of tertiary oil recovery technology, including various oil flooding methods such as flooding and flue gas flooding, is increasing. Flue gas flooding oil recovery with CO 2 Similar displacement characteristics and N 2 The advantages of oil displacement, especially for heavy oil reservoirs, the comprehensive effect of enhanced recovery is better than that of N 2 and CO 2 , and the use of flue gas in oil field production is to turn harmful substances that pollute the environment into useful resources for oil field production, which is conducive to environmental protection, so its promotion and application value is higher. During flue ga...
