Cierra In-Tank Separation Recovery Process

Cierra Tank uses state-of-the-art “cold tapping and circulation” technology to create an opening into the tank through blind flanges. This process eliminates the necessity of hot work and having to open the manways.

Cierra Total Clean Solution

Cierra’s goal is to provide a completely cleaned tank with nominal exposure to personnel. To achieve this, Cierra begins with its In-Tank Separation Recovery Process. Then solids are removed using the same technology adapted for hot washing. Solids are pumped into a separation tank where they are centrifuged and then properly disposed. Detailed cleaning is then completed manually in areas behind legs and pipework.
