Bitumen Tank Cleaning

Tank Cleaning ahead of Bitumen Tank Repairs

Client Issue

Tank Cleaning ahead of Bitumen Tank Repairs

Repairs were required to a 2.5 million litre capacity bitumen tank and the client needed the tank to be cleaned to facilitate these works.

The tank out flows and the position of man-lid meant that 60m³ of bitumen could not be drained from the tank prior to cleaning. The working temperature of the bitumen tank was 180 degrees.

Enva Approach

Tailored Programme of Works

The client specified internal tank cleaning up to .75 metres.

Enva surveyed the tank and devised a tailored programme of works which was agreed with the client. The works included the removal of solid bitumen from the floor, internally scaffolding and the removal of bitumen residue from the pipes and walls. The floor and walls were then sandblasted up to .75 metres.

Results

Over 75 tonnes of Bitumen Removed from Tank

• 60 tonnes of solid bitumen from tank floor
• 26 tonnes of bitumen residue from tank walls
• Sand blasted the tank floor and walls to .75 metres

Following the completion of Enva’s programme of works, the tank repairs were then carried out and the tank was ready for use.
