Abstract

The invention discloses a system for separating and purifying mercury in natural gas. The system comprises a separating device and a purifying system, wherein the separating device is used for separating and enriching mercury in natural gas, so as to form a first-level mercury-containing mixture; the purifying system comprises a mercury reductant carrying device, a mercury vapor carrying device and an absorbing device; the mercury reductant carrying device is connected with the separating device and is used for reducing the mercury ions in the first-level mercury-containing mixture into mercury vapor; the mercury vapor carrying device is connected with the separating device and is used for conveying the mercury vapor to the absorbing device so as to form a second-level mercury-containing mixture. The system is simple in operation, is nontoxic and pollution-free and is capable of quickly and accurately measuring the mercury content in natural gas, so that a corresponding oil-gas exploration method can be designed for the mercury content in natural gas, the exploration cost is saved, the scale benefit and development can be realized and the gap of quickly separating and purifying mercury in natural gas in the present oil gas industry can be filled.

Description

technical field [0001] The invention belongs to the fields of oil and gas exploration technology and chemical industry, and in particular relates to a mercury separation and purification system and method in natural gas. Background technique [0002] Mercury vapor content in natural gas as an identification index of natural gas origin was proposed as early as 1974 by the former Soviet scientist Н.А. The mercury content in the atmosphere (the background value of mercury in the atmosphere is 1.5-2.0 ng / m3) is 2, or even more orders of magnitude. Chinese researchers studied the mercury vapor content in a large number of oil-type gas and coal-type gas in the early 1990s and concluded that the mercury content in coal-type gas is generally higher than that in oil-type gas, and the mercury content in coal-type gas is generally higher than that in oil-type gas. The vapor content is generally greater than 700 ng / m3, and the mercury vapor content of oil-type gas is usually less than 6...
