Embodiment

[0034] The purification gas dehydration process applied to high-sulfur natural gas involved in the present invention comprises the following steps:

[0035] (a) The wet purified gas from the absorption tower of the desulfurization unit enters the lower part of the absorption tower of the dehydration unit and is in reverse contact with the dehydration solution from bottom to top, thereby removing the moisture contained in the wet purified gas;

[0036] (b) The dehydrated solution that has absorbed moisture comes out from the bottom of the absorption tower, and after being preheated by a heat exchanger, enters the flash tank to flash the hydrocarbon components in the dehydrated solution, and then enters the regeneration tower through filter filtration;

[0037](c) In the regeneration tower, part of the water in the dehydration solution turns into steam, and leaves the system from the top of the regeneration tower. The regenerated dehydration solution comes out of the reboiler, an...

Abstract

The invention discloses a purified gas dehydration technology applied in natural gas with high sulfur content. The purified gas dehydration technology applied in natural gas with high sulfur content contains steps of: removing moisture from wet purified gas, regenerating a dehydration solution and the like. The invention can be used to effectively dehydrate purified gas and reduce dehydration cost, and requires simple processes.

Description

technical field [0001] The invention relates to a purification gas dehydration process applied to high-sulfur natural gas. Background technique [0002] The removal of gas H2S can generally be divided into two categories: dry method and wet method. Wet methods include absorption method and wet oxidation method, which have high desulfurization load, but generally have disadvantages such as large power consumption, bulky equipment, high operating costs, and harsh control conditions. Dry methods include iron oxide method, zinc oxide method, activated carbon method, molecular sieve method, etc. Dry method is suitable for low-sulfur gas treatment, and is widely used for its simple process, convenient operation, high desulfurization precision and low energy consumption. The existing desulfurization processes mainly include the following types: [0003] Absorption method: Absorption method includes chemical absorption method, physical absorption method and physicochemical absorpt...
