【Q&A Question 290】November 4, 2017: What are the key points for the proper maintenance of hydrogenation catalysts? Strictly control the dry point, gum content, and water content of the crude oil ； Strictly control the bed temperature rise ； Ensure an adequate hydrogen partial pressure and a certain space velocity in the catalyst bed ； The reduction in temperature and pressure must be carried out at the specified rate ； Ensure gas flow through the catalyst bed under all circumstances ； When adjusting the volume and temperature, the operations must be done smoothly ； Maintain the H2S content in the circulating hydrogen at ≮0.1V%. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) For management purposes, if you need to view content from a few days ago, please access it through the summary post below. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html (Source: Haichuan Chemical Industry Forum)
