Embodiment 1
[0046] A sample of natural gas produced in an oil and gas field, after extraction and desulfurization with amine solution, the total sulfur was 375mg / Nm 3 , of which the hydrogen sulfide content is 12mg / Nm 3 , adopt the inventive method to carry out desulfurization test, test result is as follows:
[0047] The test temperature of natural gas desulfurization is 24°C, after being treated by the experimental device of the method of the present invention, the total sulfur of natural gas is 5mg / Nm 3 .
Embodiment 2
[0049] A petrochemical company catalytic unit produces dry gas 15000-20000 Nm 3 / h, total sulfur 100-200mg / Nm after extraction and desulfurization by amine solution 3 , wherein the hydrogen sulfide content is less than 10mg / Nm 3 , adopt the method of the present invention to build a set of gas material removal device of organic sulfur, device operation result is as follows:
[0050] The operating temperature of the dry gas desulfurization extraction tower is 25-40°C, the pressure is 0.8-1.1MPa, and the total circulation flow rate of the desulfurizer is 12-15m 3 / h, send regeneration tower rich desulfurizer flow rate 2-3m 3 / h, the operating pressure of the regeneration tower is 0.12MPa, the temperature at the bottom of the regeneration tower is 115-120°C, the temperature at the top of the tower is 90-95°C, and the total sulfur in the dry gas after desulfurization does not exceed 10mg / Nm 3 .
[0051] In summary, with the aid of the above-mentioned technical scheme of the p...
