Abstract

The embodiment of the invention provides a method, a device, equipment, a medium and a product for measuring the content of organic chlorine in crude oil, and the method comprises the following steps: obtaining a target crude oil sample, and scanning the target crude oil sample to obtain a target nuclear magnetic resonance spectrum; determining the content of target organochlorine in the target crude oil sample according to the target nuclear magnetic resonance spectrum and a pre-constructed organochlorine content analysis model, wherein the organochlorine content analysis model has a mapping relation between the nuclear magnetic resonance spectrum and the organochlorine content; and outputting the target organic chlorine content through the organic chlorine content analysis model. The organic chlorine content can be rapidly and accurately measured, and when the organic chlorine content exceeds the standard, related technicians are timely guided to correspondingly adjust the device process so as to avoid corrosion of equipment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular, to a method, device, equipment, medium and product for measuring organic chlorine content in crude oil. Background technique [0002] Crude oil contains trace amounts of organic and inorganic chlorides. During crude oil processing, due to the hydrolysis and decomposition of organic chlorides, hydrogen chloride gas may be generated, which may cause equipment corrosion problems, such as HCl-H at the top of the atmospheric tower and the top of the vacuum tower in the distillation unit 2 S-H 2 O corrosion problem, catalytic cracking fractionation tower scale corrosion problem, etc. Although there are anti-corrosion measures such as "one removal and three injections" that can slow down the chlorine corrosion rate, the problem cannot be completely solved, and the chlorine corrosion problem still occurs from time to time. Therefore, domestic and fo...
