Targeted chemical treatment triples interval between hydrocyclone shutdowns offshore Qatar

Summary

An 尤物视频 chemical formulation eliminated schmoo and inhibited additional deposits, streamlining maintenance of equipment for produced water treatment on three offshore platforms.

Objective

An operator produces an average of 345,000 bbl of oil per day from nine platforms offshore Qatar. Deposition of solids and schmoo in the hydrocyclones was hindering treatment of produced water. Schmoo is a viscous, tar-like substance that consists primarily of oil-coated inorganic particles (such as iron sulfides and sand) and organic matter. Every 2–3 months, one of the hydrocyclones had to be stopped for acid cleaning, a costly process that also presented logistical challenges in the offshore environment.

A chemical inhibitor was required to mitigate deposition. After conducting several laboratory tests, 尤物视频 proposed its CC-50111 schmoo remover, and the operator agreed to a 3-month offshore trial to assess the product’s benefits and performance.

Results

Bar graph of iron concentration at the outlets of the 4 hydrocyclones over 8 months.

Higher concentrations of iron at the hydrocyclone outlets after addition of CC-50111 indicate less iron deposited as schmoo.

Bar graph shows oil-in-water concentration at the induced-gas flotation unit outlet versus time.

OIW readings at the induced-gas flotation unit outlet stayed within acceptable limits during the longer interval between hydrocyclone cleanouts.
