ITCO Blend™ - Acid Corrosion Inhibitor is an organic free flowing liquid. It is essentially a high molecular weight amine derivative formulated to give optimum results. It contains Nitrogen but does not contain Lead, Arsenic or Chlorinated Hydrocarbons. This product is completely miscible with Hydrochloric Acid, Sulphuric Acid, etc. and it does not form sludge with the oils.
Acid Corrosion Inhibitor is used when acid attack such as Hydrochloric acid alone or mixed with Hydrofluoric acid is of extreme severity. This corrosion inhibitor is used when corrosive duty such as hydrochloric acid of 15% strength is used at temperature of 120°C at 1000 pounds of pressure per square inch. Such corrosive duties are encountered while acid fracturing of Limestone base is done. The corrosion rate expressed as loss in weight for N-80 steel, will not exceed 20 mg. Per square centimeter per 6 hours of exposure to above corrosive environment.
Acid Corrosion Inhibitor can also be used effectively in acid cleaning of Water Desalination Plants which have heat exchangers made of copper and cupro-nickel alloys.
The hydrochloric acid solution inhibited with Acid corrosion Inhibitor is best circulated through the equipment to be cleaned.
When circulation is not possible, the equipment should be filled with the inhibited acid and allowed to react for sufficient time to remove the objectionable deposits. To estimate the proper acid concentration, time etc. samples of the deposits to be removed can be tested in the laboratory prior to cleaning. If heating of the equipment or acid solution is desired to speed up the cleaning action, it should be done prior to the starting of the cleaning operation.
Manual on acid cleaning would be made on request.
The dosage of Acid Corrosion Inhibitor depends on the temperature and type of the acid used.
For 5% HCl up to a temperature of 85°C, 0.2% w/v is suggested i.e. 1000 litres of 5% HCl would require 2 Kg of the inhibitor.
When the temperature exceeds 85°C up to 115°C, a dosage of 0.3% w/v is suggested.

ITCO Blend™ - Emulsifier is an excellent surfactant to emulsify the acids (Typically 15 wt% Hydrochloric Acid) and light hydrocarbon phase (crude oil or diesel). Injection of the acid in this form (acid –in- diesel emulsion) will minimize acid-rock contact, which will result in the formation of deep worm holes. Emulsifying the acid will increase its viscosity and improve acid distribution in reservoirs. The foam will flow into the high permeability zones, causing the acid to flow into the light zones.
The acid-in-diesel emulsion consists of diesel (continuous phase) Hydrochloric acid (dispersed phase) and an emulsifier diesel act as a diffusion barrier between the acid and the rock, slowing the reaction rate of the acid with carbonate rock. This gives the acid the ability to penetrate deeper into the formation by creating wormholes and enhancing well productivity.
