【Q&A Question 088】March 29, 2018: What is the function of the crude oil buffer tank? The function of the crude oil buffer tank is primarily to provide buffering, reducing the impact of external factors on the reaction feed pump and thus ensuring a stable feed flow ； Furthermore, when external feeding is interrupted, the oil in the crude oil buffer tank can provide a certain amount of time to carry out emergency response measures. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limits on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

1. Ensure thorough mixing of the feed material; 2. Act as a buffer in cases where the supply of raw materials is interrupted due to issues outside the system, preventing the feed pump from running dry and thus avoiding interruptions in feed supply to the equipment as well as damage to the pumps; 3. By prolonging the residence time of the incoming raw materials, it is possible to allow any water contained within them to separate properly, thereby preventing large amounts of free water from entering the reaction system and causing destructive effects on the catalyst; 4. To prevent the olefins in the raw materials from oxidizing upon contact with oxygen, which could lead to an increase in pressure in the reactor, this tank is protected using fuel gas or nitrogen.
Answer: The raw material buffer tank serves four main functions: 1. To ensure thorough mixing of the feed materials; 2. To act as a buffer in cases where the supply of raw materials is interrupted due to issues in external systems, thereby preventing the feed pump from running dry and avoiding disruptions in feeding to the equipment as well as damage to the pumps; 3. By prolonging the residence time of the incoming raw materials, it allows any water contained within them to separate properly, preventing large amounts of liquid water from entering the reaction system and causing destructive effects on the catalyst; 4. To prevent the olefins in the raw materials from oxidizing upon contact with oxygen, which could lead to an increase in pressure in the reactor, this tank is protected with fuel gas or nitrogen.

1. Ensure uniformity of the raw material components. 2. Act as a buffer when the supply of oil to the tank area is interrupted. 3. Prolong the residence time of incoming materials, allowing the water layer in the oil to separate and preventing free water from entering the reactor and causing the catalyst to be damaged. 4 To prevent the olefins in the feedstock from oxidizing upon contact with oxygen, which could lead to an increase in reactor pressure drop, the tank is protected using nitrogen or fuel gas.

To act as a buffer in cases where the supply of raw materials is interrupted due to issues in external systems, thereby preventing the feed pump from running dry and avoiding disruptions in feeding to the plant as well as damage to pumps; 3. To allow more time for the external raw materials to stay there, so that any water contained within them can be properly separated, preventing large amounts of free water from entering the reaction system and causing destructive effects on the catalyst; 4. To protect the tank from oxygen exposure, which could cause the olefins in the raw materials to oxidize and lead to an increase in pressure in the reactor, by using fuel gas or nitrogen for protection.

To act as a buffer in cases where the supply of raw materials is interrupted due to issues in external systems, thereby preventing the feed pump from running dry and avoiding interruptions in material supply as well as damage to pumps and machinery; 3. To allow sufficient time for the water contained in the raw materials to separate out, thereby preventing large amounts of free water from entering the reaction system and causing destructive effects on the catalyst; 4. To protect the tank with fuel gas or nitrogen, so as to prevent the olefins in the raw materials from coming into contact with oxygen and oxidizing, which could lead to an increase in pressure in the reactor.
