Quench Systems

You can wash the Quench Settler with co-axial nozzles on a mount on ‘dummy manways’ at each end of the vessel. In addition, we circulate a hot chemical formulation for 8 -12 hours, in two stages. The chemical mobilises and temporarily emulsifies the heavy crack-gas tar deposits, to pump out to temporary tanks. We then rinse the Settler with clean water and is ready for opening.

Decontamination of Quench Towers is using a top-to-bottom cascading wash. By using this partial-fill, cascade approach, you can generate more turbulent flow, with greater cleaning action. In addition, there is much less spent solution, requiring storage and treatment.

CORE chemically decontaminate Quench Water Exchangers, in-situ. This is as a pre-treatment prior to extraction, which eliminates Benzene issues, and reduces jetting time at the wash-bay. The exchangers can be chemically washed in-situ and then returned to service without pulling, reducing maintenance costs.

We can treat all stored washing effluent in a CORE Mobile Wastewater Treatment Unit, and clean water sent to drain.
