Although this method can remove acid gas well, it still has the disadvantages of large organic sulfur and water content, high operating cost, complicated operation, and environmental pollution.
[0004] For example: Invention Patent ZL98111874.4, one-step removal of mercury, arsenic, pentamethylbenzene, hexamethylbenzene, chlorides (organic chlorides and inorganic chlorides) in natural gas has no obvious effect, and has no obvious effect on organic sulfur mercaptans, sulfide, thiophene, tetrahydrothiophene and other 26 kinds) are also deficient, such as thiophene and tetrahydrothiophene, which have poor effect on sulfur dioxide in inorganic sulfur

Embodiment Construction
[0028] Embodiment adopts the method of the present invention to carry out the purification of natural gas
[0029] see figure 1 , The purification tank 1 is installed in the furnace body, the furnace body is equipped with an electric heating element 3, and the purification tank 1 is heated externally, and the purification tank 1 is equipped with a purifying agent 2. The upper part of the purification tank 1 is connected with raw material natural gas 6 and regeneration exhaust gas pipe 8, and the lower part of the purification tank is connected with purified natural gas pipeline and regeneration nitrogen and air pipeline 7. Water and gas separators are respectively connected in series on the raw material natural gas inlet pipeline, the nitrogen or air inlet pipeline during regeneration, and the waste gas exhaust pipeline during regeneration.
[0030]The natural gas to be purified is passed through the water-gas separator from the upper part of the purification tank 1 with the ...

The invention belongs to the technical field of natural gas purifying, and particularly relates to a natural gas purifying agent and a using method thereof. A molecular sieve is adopted as the natural gas purifying agent, and the purifying agent is prepared by sintering, by weight, 19%-21% of SiO2, 19%-21% of NiO2, 19%-21% of MnO2, 19%-21% of Fe2O3, 9%-11% of Al2O3, 0.1%-0.5% of ZnO, 0.5%-2% of Fe3Al and the balance a binding agent. According to the purifying agent, impurities such as chloride (organic chloride and inorganic chloride), water, organic sulfur (26 kinds of organic sulfur such as sulfur alcohol, sulfur ether, thiophene and tetrahydrothiophene), inorganic sulfur (such as hydrogen sulfide and sulfur dioxide), carbon dioxide, petroleum, mercury, arsenic, pentamethylbenzene and hexamethylbenzene which are contained in natural gas are removed through a one-step method, the purifying efficiency is higher, the effect is better, better safety and reliability are achieved, adopted purifying equipment and operation mode are all very simple, occupied space is small, the investment is little, the cost is low, and the purifying agent is suitable for industrial application.
Description
technical field [0001] The invention belongs to the technical field of natural gas purification, and in particular relates to a natural gas purification agent and a using method thereof. Background technique [0002] Natural gas is widely used as raw material and gas source for heat treatment in the chemical and heat treatment industries. However, since most natural gas is produced from crude oil or natural gas mines, the natural gas mines are initially desulfurized and enter the city for use. If the odor is not enough , but also odorization treatment to ensure the safe use of gas by residents. Natural gas includes chlorides (organic chlorides and inorganic chlorides), organic sulfur (mercaptan, sulfide, thiophene, tetrahydrothiophene, etc. 26 kinds), inorganic sulfur (hydrogen sulfide, sulfur dioxide, etc.), in addition, it also contains a large amount of impurities such as water, carbon dioxide, petroleum, mercury, arsenic, pentamethylbenzene, hexamethylbenzene, which will...
