Weekly Topic-20090302-Can LPG tanks and oil tanks be placed together? Why?
Thread Content
Recently, my company plans to build 3 liquefied gas tanks with a capacity of 2,000 cubic meters each, and 2 oil storage tanks with a capacity of 30,000 cubic meters each. Due to the small land area, there isn’t enough space to build the two types of tanks separately ； Some people have suggested building liquefied gas tanks and oil tanks together; let’s discuss whether this is feasible Why? Please provide the most reasonable plan—what should we do? Your support is the driving force that pushes us forward! ! We earnestly ask everyone to participate actively in the discussions. Our moderators will assign different levels of scores or rewards based on the depth of the discussions, and they will also review the scores given by members! ! ! On Saturday, a “Classic Reply” will be selected from all responses, awarding 3 Charm points. At the end of the month, participants take part in the monthly evaluation; those who win are rewarded with 5 Charm points.

They must absolutely not be placed together. Because there are significant differences between the two in terms of usage and fire protection. 1. Pressure aspect: High pressure in the liquefied gas tank ； The oil tank pressure is low. 2. Fire protection: LPG tanks do not require a fire dike, whereas oil tanks must have one. 3. Fire hazard: LPG cylinders are large, while oil tanks are relatively small ； The requirements for installing instruments and carrying out maintenance work with open flames differ between the two. Recommendation: LPG cylinders should be placed as far as possible at the edge of the factory area ； The oil tank should be placed as close as possible to the process unit area.

Due to the limited land area. If the fire separation distance specified in the regulations is exceeded, the oil storage can be located underground! The fire separation distances between liquefied gas filling stations and buildings, warehouses, and substation areas, as well as the distances between storage tanks, should be in accordance with the relevant standards.

I don’t think it’s possible, because there are differences in the properties of the oil and liquefied gas stored in oil tanks and liquefied gas tanks, and the fire safety requirements aren’t exactly the same. The potential risk level of fires also varies; if possible, it’s best to keep them separate. If that really doesn’t work, maybe the suggestion for the third floor could be considered!
It’s definitely not possible. The fire protection design codes for the petrochemical industry specify this clearly. Additionally, I would like to correct the view expressed on the lower floor: fire walls must be installed when the volume of liquefied gas storage tanks exceeds 6,000 cubic meters. Someone mentioned placing oil storage tanks underground, but with two tanks of 30,000 cubic meters each, how difficult would construction be? And what about the fire protection system? It’s still recommended to follow the standards; if there isn’t enough land, then find a way to expand the facility outside the factory area. (Lack of knowledge regarding storage tanks; this is merely my personal opinion.) This post was last edited by beileim1 on 2009-3-13 at 16:51.]
Haha, I’m really excited to come and receive the award! Thank you.
Each refined oil storage tank has a capacity of 30,000 m³; it is relatively impractical to build them underground, so this suggestion is good. Could the poster consider reducing the 3 oil tanks to 2? This post was last edited by zcs002 on 2009-3-16 09:44]
They should not be arranged together. According to Article 5.2.4 of GB50160, III: Storage tanks for liquefied hydrocarbons should not be placed in the same group as storage tanks for flammable liquids.
