OXYGEN SCAVENGER PLUS 25 LTR - Wilhelmsen
NALFLEET™ Oxygen Scavenger Plus™ is a catalysed, liquid Oxygen Scavenger based on Diethylhydroxylamine (DEHA). Its volatile properties ensure distribution throughout the boiler and condensate system, and hence protects against oxygen corrosion in all parts of the system.
It minimizes oxygen induced corrosion and pitting, iron oxide deposition and scaling of feed-water lines, de-aerators, and internal steam boiler with these advanced boiler oxygen scavengers. This boiler water treatment is mainly available in two variants - powder and liquid.

Boiler Water Solid Condensate Treatment. Accepta 6309 is a solid form oxygen scavenger amine product containing DEHA.. This is a proprietary compound of diethylhydroxylamine (DEHA) which is designed to remove dissolved oxygen from the systems, while providing metal passivation.As a volatile organic it will also protect the steam distribution system from oxygen corrosion.
Choosing The Best Oxygen Scavenger for Your Boiler System
Chemical oxygen scavengers are therefore used to remove or "polish" these small amounts of oxygen remaining after the bulk of the oxygen has been removed through physical means. There are a number of different chemical oxygen scavengers that are commonly used for treatment of boiler systems.
Boiler Oxygen Scavengers are used to remove dissolved oxygen from the boiler feed water and boilers. Dissolved oxygen in the boiler is very corrosive at higher temperatures and pressures. This may lead to localized pitting and premature boiler tube failure or excessive feedwater leaks.
CORROSION INHIBITORS – Boiler Systems (Amines & Oxygen
Bio-Source provides the following Oxygen Scavengers for boiler water applications – external (preboiler), internal, and condensate treatment: DEHA (Diethylhydroxylamine) – DEHA is an excellent chemical product used to prevent corrosion by exhibiting characteristics that have gained it widespread use in industrial water treatment.

Dearators work by heating the water and venting the gases. This operation reduces oxygen in the makeup water by more than 99 percent, leaving behind oxygen concentrations measured in the parts-per-billion range. At feedwater and boiler water temperatures, even this level can create severe corrosion.

Home Chemicals Water Treatment Chemicals Boilers Oxygen Scavengers A chemical oxygen scavenger is used to remove the residual oxygen from the boiler feed water in order to protect not only the boiler but also control corrosion in the hotwell (or feed tank) and the condensate return lines.
- What is an anionic polyacrylamide used for?
- There is a wide range of uses for anionic polyacrylamides and these include wastewater treatments aids, retention aids, and strength agents in papermaking, hydraulic stimulation, and enhanced oil recovery in oil field applications, mineral processing, and as soil conditioners in agricultural uses.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
