WSB PROTECTOR II

Abstract

Sulfite based products are excellent oxygen scavengers, in removing dissolved oxygen from feedwater and boiler water treatment.

Their main advantage is that performing fast reaction, and present application low cost

The drawbacks are that:

WSB PROTECTOR II corrosion inhibitor is designed to overpass those problems by introducing into the formulation metal passivator and polymeric scale inhibitor, of the new generation type.

So WSB PROTECTOR II corrosion inhibitor passing the “evaluate your scale inhibitor” test, and repairing the magnetite protection films is a low cost, new generation total boiler water treatment, especially for boilers using soft or desalinated make-up.

Features

WSB PROTECTOR II reacts with oxygen in water almost instantaneously, even at low temperatures. This rapid rate of reaction provides greater protection to the boiler and feedwater section, especially where complete mechanical deaeration is not provided.

WSB PROTECTOR II is a liquid blend of sodium bisulfite and specially selected catalytic agents which will not interfere with steam generator operations.

WSB PROTECTOR II benefits include:

·         Highly effective, low cost, liquid, non-steam volatile oxygen binding media on basis of sodium ascorbate and sodium Bisulfite.

·         This product is especially suitable for use in non thermally deaerated feed waters, in the food and pharmaceutical industry and for direct steaming.

·         Increases equipment life by minimizing pitting corrosion.

·         Reduces energy cost by minimizing insulating iron oxide or Calcium based deposit.

·         Reduces deterioration of the steam and condensate lines by minimizing oxygen infiltration from the boilers.

·         The catalyst accelerates oxygen removal.

·         Helps protect the pre-boiler system and the boiler from unscheduled downtime due to oxygen corrosion

·         Enhances metal passivation of iron and copper, minimizing metal corrosion and resultant boiler deposition; can result in extended equipment life

·         Does not require specialized feed systems — liquid product minimizes housekeeping and mixing problems

·         Contributes no measurable solids to the boiler, so blowdown levels on sulfite programs can often be reduced — a significant energy savings

·         Highly effective alkalization media and corrosion inhibitor for steam and condensate systems.

·         Non contains free caustic, so does not induces carry over or caustic attack, under overfeed conditions, or when incoming oxygen levels will be lowered

·         Ingredients are in compliance with FDA and USDA regulations pertaining to boiler water additives

·         Non induces dangerous or corrosive gases to the steam like MEK or Hydrazine.

·         Ready to react as it is and does not require thermal activation like Methyl Ethyl Ketoxime and Carbohydrazide does.

These data are to be seen as typical values and should not be considered as specifications.

Feeding

Recommended feeding method is continuously to the feedwater line, either as a dilute solution or neat.

The dosage is dependent upon feedwater analysis as well as boiler operating conditions.

Handling precautions Wear suitable gloves and safety goggles. In case of contact immediately flush with plenty of water. After eye contact seek medical advice.

In case of spillage, absorb with sand or other absorbent materials and sweep up. Then flush the area with water.

Before use review the Material Safety Data Sheet for additional information..
