Corrosion inhibitor

Types: Low Temperature Corrosion inhibitor, High Temperature Corrosion Inhibitor, Neutralizing Corrosion Inhibitor, Neutralizer.

Low Temperature Corrosion inhibitor

This oil soluble corrosion inhibitor is used to control refining crude distillation system aqueous phase corrosion mainly caused by HCl and H2S. It helps to extend equipment run lengtht, reduce refinery Capex investment and lower daily maintaining cost.

Product features and effects:

a、Carry oil droplets to form a hydrophobic layer to prevent aqueous corrosion.

b、Adopt to wide pH environment and can effectively protect metal surface when pH changes.

c、Prevent corrosion byproducts deposition, reduce corresponding under-deposit corrosion.

d、Help tot product downstream heat exchangers or tubes.

Injection and Dosage:

It can be diluted with solvent or overhead gasoline and injected with chemical pump. It need to be injected into overhead evaporate line before where dew point corrosion occur and make sure chemical are well distributed at overhead. SANTACC sales and technical representative will provide you more detail information regarding the application method and dosage.

Physical and Chemical Properties:

High Temperature Corrosion Inhibitor

This chemical is specially designed for preventing or reducing naphthenic acid caused corrosion between 200-400℃ in refining process. It helps to control high temperature corrosion in organic phase environment, protecting equipment for longer run-length, reduce contaminant for related fuel product stream.

Features and advantages:

a、Specially design for high temperature naphthenic acid corrosion control.

b、Form uniform, persistent protection film on equipment and pipeline surface to provide good corrosion inhibition.

c、Do not have known negative effect on downstream unit or other chemical additive.

Injection and Dosage

It can be added with corresponding process stream and injected with chemical pump. It needs to be injected into pipeline before where corrosion occurs and use injection quill to make sure chemical are well distributed. Dosage depends on the stream properties and corrosion severity. SANTACC sales and technical representative will provide you more detail information regarding the application method and dosage.

Neutralizing Corrosion Inhibitor

This chemical contains integrated neutralizer and corrosion inhibitor to control pH and prevent aqueous phase corrosion. .It was mainly used for refining crude distillation overhead HCl, H2S caused aqueous phase corrosion control.

Product features and effects:

a、Strong ability of neutralizing can effectively control dew point area acid. corrosion.

b、Easy maintain overhead pH in appropriate range, forms water soluble salts and low salt deposit and related under-deposit corrosion risk.

c、Good synergy between neutralizer and corrosion inhibitor to provide corrosion control.

d、ormulated with demulsifer to prevent oil/water emulsion in overhead condensate water.

Injection and Dosage:

This chemical can be diluted to 5-20% water solution and injected into overhead evaporate line with chemical pump. Dosage is decided based on condensate water Fe ion content. SANTACC sales and technical representative will provide you more detail information regarding the application method and dosage.

Neutralizer

It is a formulated amine type of chemicals specifically designed to control low pH caused corrosion problem at crude distillation overhead, especially at dew point area. By neutralizing the corrosion species, it helps control overhead pH and corrosion to extend equipment run length, reduce maintaining cost.

Product features and effects:

a、Effectively control overhead condensate water pH

b、Fast dissolve in water and neutralize HCl to control pH to solve dew point HCl caused corrosion.

c、Forms low melting point salt with HCl and exist as liquid in tower to reduce deposition and under deposit corrosion risk.

Injection and Dosage:

This chemical should be injected purely or diluted with water into overhead evaporate line with chemical pump. An appropriate inject quill should be used for better distribution in the system and stainless steel should be used for injection pipeline. Dosage should be decided based on overhead water HCl amount and controlled for condensate water pH between 5.5 and 7.5. SANTACC sales and technical representative will provide you more detail information regarding the application method and dosage.
