2natural gas Deng acidic materials can form corrosive liquids, causes the corrosion of pipeline and equipment.In addition, under certain pressure and temperature, some component and aqueous water in natural gas also can form gas hydrates, and when serious, these hydrates can stop up pit shaft.Therefore will be through the operation of desulfurization and decarburization for raw natural gas.Before desulfurization, need to carry out pretreatment the most C5+ in the unstripped gas in natural gas are removed, and in prior art, pre-processing device heavy hydrocarbons content after processing is high, does not reach requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas separated pre-processing device, can effectively remove most C
5 +composition.
The utility model adopts following technical scheme: the separated pre-processing device of a kind of gas, comprise compressor, first grade desulfurizing tower, two-grade desulfurizing tower and three grades of desulfurizing towers, first grade desulfurizing tower, two-grade desulfurizing tower and three grades of desulfurizing towers are arranged in parallel, and by separate valve, control turnover gas; The air inlet of first grade desulfurizing tower, two-grade desulfurizing tower and three grades of desulfurizing towers is connected with the gas outlet of a gas-liquid separator, and the air inlet of described gas-liquid separator is connected with the gas outlet of compressor by a regeneration gas cooler and valve.
Further, described compressor outlet place is provided with valve combination, and described valve combination is comprised of 4 valves, after wherein two valves are one group of series connection, between group and group, forms parallel-connection structure.
Further, wherein between one group of valve, draw tube connector and be connected with the air inlet of first grade desulfurizing tower, two-grade desulfurizing tower and three grades of desulfurizing towers by valve, between another group valve, draw reserved tube connector.
Further, this equipment also comprises auxiliary desulfurizing tower, the air inlet of described auxiliary desulfurizing tower is connected with reserved tube connector, after the gas outlet of auxiliary desulfurizing tower is connected with an electric furnace, by valve, is connected with the gas outlet of first grade desulfurizing tower, two-grade desulfurizing tower and three grades of desulfurizing towers.
Compared with prior art, beneficial effect is the utility model:
