Pressurized tanks

[engr2GW]

Hello,

I have heard about pressurized tanks, I believe covered under API 650? but I have not seen widespread use in the onshore oil and gas side, especially for tank batteries and shale oil. I work mostly in the Eagle Ford. Is there a reason or some reasons that it is not commonly being used? is it one of those technologies that really work but so expensive that folks just stick with what they're used to, i.e. API 12 tanks?

Thanks for you insight.

As much as possible, do it right the first time...

IMO, it may be based on several factors, such as the process requirement, fabrication convenience, economy, etc.
API 12 is applied for the shop fabricated tank while API 650 (up to 2psi) or 620 (up to 15psi) can be used for the field erection tank.

For tank batteries, quantity has a quality all its own. Individually engineered field erected tanks have a schedule associated with them that is not generally conducive to gathering tanks based on the storage requirement per site. For storage tanks, it is more common to use some internal storage pressure to minimize evaporation losses, and may be required for emissions regulations.

API 12F tanks are an attractive option for many purchasers, as they can be a single line item purchase order. If you seek larger than the shop fabricated API 12F tanks, there are standard field erected API 12D (welded) or API 12B (bolted) solutions that may meet your needs.
