3. The Market…
For every gallon of crude oil processed in a refinery ~ 2.5 gallons of water are required.
A large refinery will process around 10 million gallons of wastewater a day at an annual cost of ~ $40,000,000.00

4. The Market…

5. Overview

Discuss current market trends and opportunities

6. Typical Applications and Industries
Refinery wastewater
Chem & PetroChem
High FREE Oil content
This flowsheet is typically seen in the following applications:
Refinery Wastewater plants
Washdown stations: (Places where a process involving oil is washed into a drain ie. Truck wash stops, oil tank cleanout stations etc. This also includes oil tanker ballast washdown stations.)
Food & Dairy
Chem & PetroChem
Any wastewater stream with high FREE oil content.
CITGO Lake Charles, LA

8. Oleophilic = Oil Loving
Oil drum skimmer is used to recover the layer of free oil before chemical addition

9. Chemical Addition Add a pinch of coagulant We’re using Alum
This will drop the pH to about 3.7, breaking the emulsion
Add a dash of caustic
This raises the pH back up prior to adding a flocculant
Finish with a touch of polymer to taste
Helps aide in flocc formation
