Chemical Screening
Chemical screening is a preliminary analytical process to identify the chemical compounds present in a sample. This process is usually performed quickly to provide a general overview of the chemical composition, whether for research purposes, quality control, or the detection of hazardous substances.
Scope
Chemical screening is necessary in production processes, refineries, transportation pipelines, and storage tanks. The main objectives of this testing are to:
- Determine the effectiveness of chemicals under actual operating conditions.
- Optimizing the use of chemical additives (cost efficiency).
- Prevents production problems such as emulsion, corrosion, paraffin deposition, and H₂S hazards.
- Supports flow assurance and asset integrity management.
Types of Chemical Screening Tests
General Methodology
Laboratory Bottle/Beaker Tests
For initial screening of chemical effectiveness.
Jar Test Simulation
Chemical interaction test under semi-process conditions.
Dynamic Flow Loop Test
