Re: [MW:4199] ...can be designed in accordence with API 650...?

Hi Manohar

 

API 650 tanks are generally for storage service at atmospheric pressure. Also the bottom of the API 650 tanks are uniformly and fully supported.Hence not applicable in this case.

In your case it is an agitated vessel which will have certain amount of internal pressure according to the intended service conditions.So this is a pressure vessel which can be designed as per ASME section VIII div I with special process design of agitator assembly. Leg supports with lugs can be designed as per the methods described in process equipment design books such as Brownell&Young.

The entire design of the vessel can be performed using design softwares such as PVelite.
