Equipment (tank train) – where to go? (10)

This post was last posted by High-End Atmosphere on 2014-5-5 15:11 Editor Dear loyal listeners and great friends of Haichuan, I am going out tomorrow and may not be able to access the Internet for a day, so I sent the posts that were originally scheduled to be updated every Tuesday and Friday in advance today. You can discuss more and communicate more. The great Labor Day has passed. Please take heart and let everyone speak freely. Only by sparking more wisdom can the alluring charm of Haichuan be reflected. Haha, let’s start today’s chattering. Arrangement of the tank group in the tenth phase of the device. The inner tank group of the device refers to the containers arranged on the edge of the device and in the device. Here, the flammable gas and liquefied hydrocarbon media are mainly concentrated. In the project device, in order to minimize the fire prevention distance of the device area frame, the factory building and the scope of the explosion hazard zone, try to centrally arrange the equipment for flammable gas and liquefied hydrocarbon media. Outside the device, I have talked about it before in the first series of "Building Regulations & Petrochemical Regulations". Inside the device, storage tanks are also classified according to their size. First, combustible gases or combustible liquids less than or equal to 1,000 cubic meters can be arranged within the frame, larger than 1,000 cubic meters and less than 5,000 cubic meters, and groups of single tanks with a volume of no more than 3,000 cubic meters are concentrated at the edge of the device. Liquefied hydrocarbons can be arranged within the frame within 100 square meters, and tank groups with a single tank volume of 100 to 500 square meters and less than 300 square meters can be arranged at the edge of the device. The spacing shall be in accordance with the spacing specified in the "Fire Protection Spacing for Equipment and Building Layout" table in 50160. The pumps related to the storage tank should be arranged outside the fire dike. The specific fire separation distance from the device is not limited. Since I am talking about flammable liquid liquefied hydrocarbon pumps, I will talk about it because during this period, many friends asked about the layout and distance of liquefied hydrocarbon pumps when they re-read the previous series. Let’s talk about the special pump for the tank group first. The dedicated pump area of ​​the tank group is different from the pump for installing the tank group. The distance for installing the tank group is not limited as long as it is outside the fire dike. ； However, the dedicated pump area for the tank group is different. It is definitely arranged outside the fire dike first, but it is larger than the Class A A pump area. ； Category A and B and Category B are larger than 12m, and those with a volume of less than 500 cubic meters and fixed roof storage tanks are larger than 10m. ； The distance from floating roof and internal floating roof storage tanks and Category C and A fixed roof storage tanks should not be less than 10m, and the distance from internal floating roof storage tanks and Category C and A fixed roof storage tanks less than or equal to 500 cubic meters should not be less than 8m. What is mentioned above is mainly the word "area". When the dedicated pump is a separate pump or a separate pump for one use and one standby, there is no distance restriction and it only needs to be outside the fire embankment. Let’s talk about flammable liquids and liquefied hydrocarbon pump rooms. In a pump room, pumps with operating temperatures above and below the auto-ignition point and liquefied hydrocarbon pumps need to be arranged in different rooms, separated by firewalls. In addition, we always see that some pump rooms are very large and have several pumps placed in the middle. Because the distance between the pumps for Class A, B, and A flammable liquids and liquefied hydrocarbon media whose operating temperature is higher than the auto-ignition point should not be less than 4.5m from the doors and windows of the pump room, the main consideration is fire conditions. If there are only one or two pumps, they can be arranged in the same pump room together with other pumps for flammable liquids. It is not suitable to set up pits and trenches in the Class A and Class B A liquid pump rooms, and ventilation should be provided at the top and bottom according to the nature of the medium. Category A, B, and C process equipment should not be placed above this type of pump room. This issue is too theoretical. There is no way to avoid it. When it comes to the issue of distance, it is inevitably boring. Finally, I will give you some pictures of the tank set. Here are a few tall spherical tanks, some with sprays and without sprays. Take a look at the ones that are spraying. If you have good pictures, please share them. ---------------------------------------I am the dividing line--------------------------------------------- Equipment - where to go?
