As per attached schematic drawing, I need to design a Styrene storage tank of least inventory of 145 m3 to store styrene monomer at max ambient temp of 35 oC. What I have designed is a 145 m3 (H=6.4 m & D=5.4m) vertical fixed roof tank made from carbon steel with design press of 10 mbarg; the tank is equipped with :
I was extremely wondering if anybody could advice me the followings:
1-Is the design press OK?
2-What I have considered is a bared tank, Is it needed to be insulated?
3 -In order to observe safety issues , and maybe eliminate any polymer generation (of course styrene will contain more than 15 ppm TBC), do I need double or triple smaller tank , instead??
4-is Carbon steel ok for SM?
5-Do I need to inject air to the tank to keep O2 concentration in 10-15 ppm thus accelerating TBC performance and inhibiting the polymer formation? If so any advice??
6-What about any requirement of double hull tank for better cooling?
