The answer key will be available after responding; scoring is based on answering the key points. 1. It damages the catalyst and increases the reaction pressure drop ； 2. High exchange blockage ； 3. Furnace tube coking
Answer: ① The function of the crude oil filter is to remove particulate impurities from the oil; this is especially important for devices that process oil on a secondary level, as such oils contain many particulate impurities； ②When the feed oil filter short-circuits, the feed oil will coking in the high-pressure heat exchanger, blocking it and reducing the heat exchange efficiency ； ③Furthermore, once particulate impurities enter the reactor, they will deposit within the bed layer, increasing the reactor pressure drop ； ④To ensure the stable and efficient operation of the device, it is necessary to prevent short circuits in the crude oil filter.
To filter out mechanical impurities in the crude oil,
It can cause an excessive pressure drop in the reactor due to blockage by solid particles in the feed
1. It damages the catalyst and increases the reaction pressure drop； 2. High exchange blockage ； 3. Furnace tube coking
Filters are used to remove impurities from the raw material; especially since processed oil contains many impurities, short circuits can lead to the formation of coke in the high-pressure heat exchanger, thereby blocking it and reducing its thermal efficiency； Entering the reactor, it will deposit on the bed layer, leading to an increase in pressure drop ； So, short circuits need to be prevented
①The function of the crude oil filter is to remove particulate impurities from the oil; this is especially important for devices that process oil further, as such oils contain a high amount of particulate impurities； ②When the feed oil filter short-circuits, the feed oil will coking in the high-pressure heat exchanger, blocking it and reducing the heat exchange efficiency ； ③Furthermore, once particulate impurities enter the reactor, they will deposit within the bed layer, increasing the reactor pressure drop ； ④To ensure the stable and efficient operation of the device, it is necessary to prevent short circuits in the crude oil filter.

It fails to provide filtering functionality and can easily damage the equipment
