Question: Why is emergency steam required for the feed to the catalytic riser? Answer: It is to ensure that the catalyst in the lift pipe remains fluidized after the feed is interrupted, and to prevent accidents caused by oil and gas flowing into the regenerator. http://bbs.hcbbs.com/static/image/hrline/1.gif http://bbs.hcbbs.com/static/image/hrline/2.gif The answers will be announced automatically in two days.

To ensure that the catalyst in the riser remains fluidized after feed interruption, and to prevent accidents caused by oil and gas flowing into the regenerator.
“It also prevents oil and gas from flowing into the regenerator, which would otherwise cause yellow smoke to emerge from the chimney or lead to more serious accidents. ”It refers to emergency situations where the outlet of the settler is blocked (such as when the oil-gas butterfly valve gets stuck), and feed cannot be stopped in time; as a result, the pressure in the settler system exceeds that in the regenerator. The oil and gas from the settler push all the catalyst stored in the stripping section into the regenerator where it burns, causing yellow smoke to emerge from the chimney in mild cases, and explosions in severe cases
To ensure that the catalyst in the riser remains fluidized after feed interruption, and to prevent accidents caused by oil and gas flowing into the regenerator.
Ensure normal flow between the two catalyst vessels even when the feed is cut off
To ensure that the catalyst in the riser remains fluidized after feed interruption, and to prevent accidents caused by oil and gas flowing into the regenerator.
To ensure that the catalyst in the riser remains fluidized after the feed is interrupted, and to prevent accidents caused by oil and gas flowing into the regenerator
Accident steam is fed into the riser to ensure that the catalyst within the riser remains fluidized after feed interruption, thereby preventing clogging. It also prevents oil and gas from flowing into the regenerator, which would otherwise cause yellow smoke to emerge from the chimney or lead to more serious accidents.
To ensure that the catalyst in the riser remains fluidized after the feed is interrupted, and to prevent accidents caused by oil and gas flowing into the regenerator
Answer: Accident steam is fed into the lift tube to ensure that the catalyst within it remains fluidized after feed is interrupted, thereby preventing clogging. It also prevents oil and gas from flowing into the regenerator, which would otherwise cause yellow smoke to emerge from the chimney or lead to more serious accidents.
To ensure that the catalyst in the riser remains fluidized after interrupted feeding, so as to prevent clogging. At the same time, it prevents oil and gas from entering the regenerator, avoids yellow smoke coming from the chimney, and prevents more serious accidents
