Could you please advise if you are able to perform the Water Clarification Assessment as per below requirements?Kindly confirm your ability to perform it by today and advise if you require any further information in order to submit your quotation accordingly.
Objective
Evaluation of the impact of the back-produced ASP fluids on the PWT process, more precisely on the water clarification process. Evaluation of different flocculent/coagulant chemistries.
Deliverables
Results of the jar tests (max.12 max for the screening step and max. 6 for final tests with water quality analysis) and recommendations on the best performing water clarifiers according to the experimental conditions.
Workflow
1. A screening step on one ASP case at a fixed oil content: a maximum of 4 chemicals at 3 different concentrations can be tested. The evaluation will be carried out by observing the precipitation of the polymer and the quality of the water. At the end of this stage, one or two best chemicals will be selected.
2. Based on the screening results, 3 different ASP cases will be evaluated with the best selected candidates. The residual oil content after Jar test will be measured by liquid/liquid extraction with dichloromethane and UV measurement, and the sludge volume will be estimated.
Protocol
- Water clarifiers screening through Jar tests (adapted ASTM D2035)
- Introduction of clarifier into 400 ml of produced water at 300 rpm,
- 20 minutes of static conditions.
- Temperature: room temperature
- Efficiency is assessed with visual inspection, turbidity on a sampling and oil content by solvent extraction and UV analysis
- Sludge volume estimation by filtration
