Is there any distance requirement between the methanol storage tank’s fire dike and the multi-story framework of the methanol distillation tower?

Detailed Regulations Table 4.2.9, Petrochemical Regulations Table 4.2.12

There’s no requirement for a fire barrier around your methanol distillation tower, right? There are requirements regarding the distance between the storage tank and the methanol distillation tower

There are requirements regarding the distance between the storage tank and the distillation tower

Take a look at GB50160; it should contain it there

There’s something wrong with the way you phrased this question, as it’s not clear what the specifics of the project are, nor which specifications (or standards) should be used as a reference. Regarding your question specifically: According to the Building Code (GB50016), there are specified distances required between the fire dike surrounding methanol storage tanks and the multi-story framework of the methanol distillation tower. The multi-story framework of the methanol distillation tower is considered a structure, but it cannot be treated as an ordinary structure. The safety distance required for an open-type building without any enclosing structure is greater than that for a closed-type factory building (this can be confirmed through clause 4.2.9 of GB 51283) ； Referring to the Precision Standard (GB 51283) and the Petrochemical Standard (GB 50160), there is no specified distance required between the fire dike of the methanol storage tank and the multi-story framework of the methanol distillation tower; the relevant distance is measured from the outer wall of the tank to the outermost edge of the multi-story framework of the methanol distillation tower (or, in the case of any external equipment, to the outermost edge of that equipment – in any case, it’s the nearest outer edge). The relevant provisions are those mentioned on the second floor: 4.2.9 (GB 51283) and 4.2.12 (GB 50160).

There are still doubts: 1. According to the Building Code (GB50016), there is a required distance between the fire dike surrounding the methanol storage tank and the multi-story framework of the methanol distillation tower. Since the multi-story framework of the methanol distillation tower is considered a structure, why should the distance be greater than that required for enclosed factories? Which specific provision specifies the distance requirement between the multi-layer framework of the methanol distillation tower and the fire dike of the methanol storage tank? 2. There is no specific distance requirement between the fire dike of the methanol storage tank and the multi-layer framework of the methanol distillation tower; the distance in question is measured from the outer wall of the tank to the outermost edge of the multi-layer framework of the methanol distillation tower – in other words, to the nearest outer edge. So, if that framework does not belong to the methanol distillation tower and there are no Class A, B, or C equipment inside it, is there still a need for a certain distance from the framework? Do I still need a card? Looking forward to your advice!

What on earth are you trying to do? Does the device frame actually have a methanol distillation unit? You never discussed your project at all throughout. Actually, since you already have a methanol tank, just follow Document No. 76.
