The invention provides a method for detecting a loss way and the loss quantity of desulphurized organic components in a flue gas desulphurization system, and a technology for desulphurizing regenerable flue gas by using the method. The method comprises the steps of: respectively adjusting a solution to be tested and a plurality of standard solutions until to strong acidity; respectively heating and oscillating the solution to be tested and the plurality of standard solutions; respectively detecting carbon elements in the plurality of standard solutions, so as to form a linear relation between the concentration of the desulphurized organic components of the standard solutions and detection result data of a carbon element; detecting a carbon element in the solution to be tested; and obtaining the concentration of the desulphurized organic components in the solution to be obtained according to the linear relation. By adopting the method, the loss reason, the loss way and the loss quantity of the effective desulphurized components can be rapidly judged. Thus, a detection technology support and basic test data are provided for adjustment of technologies of recycling of a desulphurized organic amine component, and determining of the opportunity and the quantity of supplying fa resh desulphurized solution to maintain balanced and stable operation of the desulphurization system.

Description

technical field [0001] The invention relates to the technical field of detection and analysis, more specifically, to a method for detecting the loss path and amount of desulfurization organic components in a flue gas desulfurization system, and a method for detecting the desulfurization organic components in the flue gas desulfurization process. A renewable flue gas desulfurization process that monitors the loss of components in real time. Background technique [0002] In the prior art, the flue gas desulfurization process usually uses a desulfurization solution (such as organic amine desulfurization solution, etc.) to absorb sulfur oxides (such as sulfur dioxide and sulfur trioxide) in the flue gas at a lower temperature, and then Desorb the sulfur oxides absorbed in the desulfurization solution at a high temperature to obtain sulfur oxide gas with higher purity, and at the same time obtain a desulfurization solution that restores the ability to absorb sulfur oxides, that i...

Problems solved by technology

This type of analysis method is complex and cumbersome to operate, the material consumption of chromatographic columns and other detection instruments is large, and the inspection process is long. Usually, it takes 6 to 12 hours to analyze a sample, which is difficult to meet the needs of real-time monitoring of the on-site operation status of the desulfurization system.

In addition, for the existing gas chromatography-mass spectrometry (GC-MS) analysis method, during the detection process, moisture will greatly damage the expensive capillary chromatographic column, and the pretreatment of sample distillation and separation is complicated and time-consuming. Ion source, capillary column, sampling system, quadrupole mass spectrometry separation system and other instruments have high maintenance frequency and high cost, and the inspection cycle and analysis cost are relatively high
