Embodiment 1
[0020] the solution
[0021] The test results show that the absorption capacity and purification degree of the solution are significantly improved by using the solution formula, the consumption of regeneration steam is reduced, the energy consumption is low, and the operation flexibility is large.
Embodiment 2
[0023] A natural gas processing unit, CO in crude natural gas 2 Content about 6% (v%), H 2 S content about 12% (v%), organic sulfur content about 230mg / Nm 3 , The formula of the technical solution is: 30% by weight of N-methyldiethanolamine, 10% by weight of diisopropanolamine, 10% by weight of TBEE, 5% by weight of water, and the remaining components are sulfolane. In the treated natural gas, H 2 S content about 15mg / Nm 3 、Organic sulfur content is less than 150mg / Nm 3 , CO 2 The content is about 2.7% (v%), and the product gas meets the national standard.
