Guangzhou Petrochemical successfully developed a mobile online hydrogen sulfide analysis system

Recently, the mobile online hydrogen sulfide analysis system innovatively developed by Guangzhou Petrochemical was put into use for the first time in the hydrocracking unit, and after 3 consecutive days of online monitoring and manual comparison, the mobile online hydrogen sulfide analysis system data is consistent with the trend of manual analysis data, marking the successful

Hydrogenation catalysts used in production plants in the petrochemical industry generally need to be pre-vulcanized to activate catalyst activity

In order to quickly detect the hydrogen sulfide concentration during the pre-vulcanization process of the catalyst, reduce the safety risk of sampling analysis, and improve the efficiency of sampling and analysis, the inspection center and technical service providers set up a technical research team to jointly develop a mobile online hydrogen sulfide analysis system for catalyst pre-vulcanization to achieve unattended real-time monitoring

The technical research team carefully inspected the on-site process conditions of each device, formulated the design scheme of the hydrogen sulfide analysis system, and implemented the working methods, operating methods, materials of the pretreatment system, selection of components and other contents and details of the analysis system one by one to ensure the reliability

After the mobile catalyst pre-vulcanization online hydrogen sulfide analysis system completed the integrated assembly, it began to conduct multiple rounds of accuracy and stability tests in the laboratory of the inspection center, and all the indicators met the requirements

In the next step, Guangzhou Petrochemical will continue to summarize its experience and promote the use of online hydrogen sulfide analysis system in various hydrogenation units to achieve fully automatic real-time detection
