Summary
Product identification
Butaclean* 4702 corrosion inhibitor
Description and use
Butaclean 4702 is a concentrated, water-based, semi-polar, high molecular weight blend of organic filming inhibitors used to protect against corrosion. It provides corrosion protection by adsorbing onto metal surfaces to form a protective monomolecular film. It protects against corrosion caused by hydrochloric acid, carbonic acid, hydrogen sulfide, and other inorganic and organic acids, along with oxygen.
Butaclean 4702 is effective in hydrocarbon streams over a wide pH range, with best results obtained in the mid to low pH range.
Typical applications
Butaclean 4702 is specifically designed for use in butadiene, isoprene, and elastomer units.
Treatment
Proper treatment levels depend on the severity of conditions at a given installation. A SUEZ representative will assess each application to provide cost-effective recommendations for treatment rates and control procedures.
Feeding
- Feed at the rate specified by the SUEZ representative, following a system survey.
- If the system is untreated or fouling deposits are present, begin feeding at low rates and gradually increase to the recommended maintenance dosage.
- May be fed neat directly from the shipping container or diluted with water.
- For consistent protection, feed continuously via a chemical proportioning pump.
- Injection point should be at least 15 pipe diameters upstream of overhead condensers.
- Dispersion can be achieved using a dispersion quill or spray nozzle and a reflux slipstream.
- Acceptable metallurgy for feed systems is stainless steel. Avoid carbon steel.
Evaluation
Treatment effectiveness is evaluated using corrosion test coupons, corrosimeter probes, tail water analyses for iron and copper, and visual inspection of equipment.
Safety precautions - Typical properties
A Material Safety Data Sheet (MSDS) with physical properties and detailed safety information is available by contacting your SUEZ representative.
