Hydrogen circulation machine control system and hydrogen-to-oil ratio adjustment
Thread Content
Which manufacturer’s control systems are used for the hydrogen circulation pumps in all these **devices? What is the typical hydrogen-to-oil ratio for the hydrogenation of gasoline, diesel, and paraffin oil? Is it adjusted frequently?
The hydrogen-to-oil ratio in the wax oil hydrogenation process is around 1000–1125:1. This ratio is controlled based on the sulfur and nitrogen content of the feedstock, the degree of reaction, and the amount of tail oil removed; it is not adjusted frequently
Around 1000; it’s not changed easily. Slight adjustments are made based on the actual production conditions~~~~
Diesel hydrogenation is generally around 600 to 700, I guess
Our factory is about to set the hydrogen consumption target! It has to be adjusted
The hydrogen-to-oil ratio is determined by the catalyst manufacturer; it’s sufficient to keep it above that value. It’s up to the circulating hydrogen supplier to consider your company’s bidding process
There is still a certain difference between the hydrogen-to-oil ratio and the specific consumption; the specific consumption of hydrogen depends to a greater extent on factors such as the composition of the raw materials and the degree of reaction.
The specific hydrogen consumption needs to be considered from several aspects related to hydrogen use in order to avoid wasting hydrogen; the hydrogen-to-oil ratio is not the key to reducing hydrogen consumption.
Hangqi, ITCC/SIS: over 1100, with a control range of 800–2000:1; when the feed composition remains constant, the variation is minimal
