Temperature at startup of catalytic feedstock oil
Thread Content
What temperature do you control during the startup of the catalytic feed oil?
Is it the temperature of the feed entering the unit, the temperature of the three-way circulation of the feed, or the temperature of the feed entering the lift pipe?
Between 190 and 230, we usually stay around 210
The temperature of the crude oil entering the nozzle is the temperature we want
Studies have shown that, while maintaining the same reaction temperature, for every 20-degree decrease in the preheating temperature of the raw materials, the reagent-to-oil ratio can be increased by 0.262； An increase in the oil-to-catalyst ratio helps to improve the microreactivity of the catalyst. Under the properties of light feedstocks, we can control it as low as 180, while for heavy oil it is 220.
Will going any higher affect the agent-to-oil ratio? We usually keep it at 230 degrees
250 degrees Celsius is ideal; it should not be lower than 220 degrees Celsius
Depending on the properties of the raw materials, the temperature should be between 180–250°C; we control it at 180–220°C.
