Embodiment Construction

[0078] The sample detection schematic diagram of the present invention is as figure 1 shown. A branch with a test sample pool is set on the material pipeline, and an online mid-infrared spectrometer is used to detect the material in the sample pool.

[0079] The detection steps are as follows:

[0080] (1) Calibration model establishment

[0081] Use gas chromatography to measure the content of olefins, alkanes and alkynes in 100 Fischer-Tropsch synthetic oil samples; then scan each sample through the sample cell for mid-infrared spectroscopy, and select the C=C bond at 3100-3010cm -1 It is the characteristic spectral region; the C-C bond is at 2975~2800cm -1 It is the characteristic spectral region; C≡C bond is at 3300~2150cm -1 is the characteristic spectrum area, the response value of the above-mentioned characteristic spectrum area is correlated with the content of olefins, alkanes and alkynes measured by gas chromatography in the sample, and the calibration model is r...

Abstract

The invention relates to adsorption equipment capable of being monitored on line. The adsorption equipment comprises an on-line mid-infrared spectrum detection system, a branch with a test sample poolis arranged on a material pipeline needing on-line monitoring, and an on-line mid-infrared spectrometer is adopted to detect materials in the sample pool. The adsorption equipment capable of being monitored on line can carry out real-time on-line detection on the concentration of materials in the adsorption equipment.

Description

technical field [0001] The invention belongs to the technical field of adsorption separation, and in particular relates to an adsorption device capable of online monitoring. Background technique [0002] Adsorption equipment is a commonly used separation equipment. Adsorption equipment includes fixed bed adsorption equipment and simulated moving bed equipment. The simulated moving bed equipment has the advantages of high production efficiency, less consumption of organic solvents, large mass transfer driving force, and convenient automatic continuous production. It is widely used in petrochemical, food industry and pharmaceutical fields. It is a complex industrial process and affects Non-linear, non-equilibrium, non-ideal, multi-degree-of-freedom periodic process with many factors. [0003] The simulated moving bed divides the fixed adsorption bed into many sections, which are filled with adsorbents, and the liquid between the sections cannot be directly circulated. Each ...
