Corrosion inhibitors

Water soluble Corrosion inhibitors

The presence of water, acids, acidic gases, high levels of oxygen, and brine creates an ideal environment for corrosion to occur. To combat this issue, TCOR 21XX series _a water soluble corrosion inhibitor_ has emerged as a vital solution in the oil and gas industry.

TCOR 21XX series contains surfactants that possess unique properties, allowing them to partition between the oil and water phases. These inhibitors have a hydrophilic group that adsorbs onto the metal surface, while the hydrophobic group forms a water-resistant organic film. This film acts as a protective barrier, preventing corrosive species from encountering the metal surface. We have designed these inhibitors to form a strong film on the metal surface, making them suitable for various metallurgies and providing excellent stability over a range of pH and temperature values.

TCOR 21XX series can protect the metal surfaces from corrosion caused by carbon dioxide (CO₂), hydrogen sulfide (H₂S), organic acids, oxygen, bacteria, and other corrosive agents present in the water phase.

Water soluble corrosion inhibitors can be classified into different categories based on their chemical composition, such as organic amines, imidazolines, quaternary ammonium salts, phosphonates, polymeric compounds, and green inhibitors.

In the oil and gas industry, corrosion poses significant risks to equipment and pipelines, leading to production disruptions and economic losses.

Oil soluble Corrosion inhibitors

In the world of oil production, ensuring the longevity of equipment and infrastructure is paramount. Corrosion, a natural process that can lead to devastating consequences, poses a significant threat to the efficiency and safety of oil production operations. Ferrous metals are susceptible to corrosion in the presence of air and water, a process that is accelerated by the presence of H₂S, sulfides, and other contaminants. Therefore, as H₂S increases the rate of corrosion, industries use H₂S scavenger to reduce the toxicity and corrosiveness of the environment (In order to know more about H₂S scavengers, click here.).

Chemical Tasfyeh Company have developed Oil-soluble corrosion inhibitors under the name TCOR 29XX series. This class of compounds specifically designed to prevent or mitigate the damaging effects of corrosion in the oil production process. Unlike traditional water-based inhibitors, oil-soluble inhibitors are formulated to seamlessly integrate into the hydrocarbon-rich environment, providing superior protection against the corrosive elements present in oil and gas production.  Totally, oil soluble corrosion inhibitors:

• Enhanced Protection: Oil-soluble corrosion inhibitors offer a higher level of protection against corrosion due to their compatibility with the oil and gas mixture. This ensures that critical components, such as pipelines, well casings, and production equipment, remain safeguarded against degradation and premature failure.
• Cost Efficiency: By preventing corrosion-related downtime and equipment replacements, oil companies can save substantial costs in maintenance and repairs. Additionally, the prolonged lifespan of infrastructure contributes to more sustainable and economically viable operations.
• Improved Operational Efficiency: The consistent use of oil-soluble inhibitors helps maintain the integrity of production processes, leading to uninterrupted operations and optimized efficiency.

Phosphate based Corrosion inhibitors for oxygen scavengers

Chemical Tasfyeh Co. manufactures mono and diester ratio of phosphate esters. A high monoester content produces a more even distribution of the inhibitor (packing of adsorbed molecules) on the surface of the metal (surface film). Hydrophobic tail of surfactant and the degree of ethoxylation is also important. It determines the wetting, surface tension reduction and emulsification attributes of the phosphate ester. Chemical Tasfyeh company’s corrosion inhibitor ranges may be used on their own, or blended into cost effective formulations.

Depending on the design of the hydrocarbon tail of the phosphate esters, I can prepare an anti-corrosion solution in oil and disperse in water or a water-soluble anti-corrosion. The phosphate esters are recommended for controlling corrosion in sweet and sour conditions, and high shear applications. The esters are recognized as forming highly persistent films on metal surfaces. They are also useful for mitigating the effects of naphthenic acid corrosion in refineries

Hydrostatic Testing

Hydrostatic testing is an essential process in various industries, including oil and gas, plumbing, and manufacturing. It involves subjecting pressure vessels, such as pipelines, gas cylinders, boilers, and storage tanks, to high-pressure fluid to assess their strength and identify potential leaks. The integrity of these systems is crucial to prevent catastrophic failures that can result in significant damage and safety hazards. In this article, Chemical Tasfyeh Co. will explore the importance of hydrostatic testing, the role of corrosion inhibitors in preventing electrochemical corrosion, and the best practices for managing hydro-test waters.

The hydrostatic testing process is a widely accepted industry standard for evaluating the structural integrity of pressure vessels. By subjecting these vessels to high-pressure fluid, typically water, any weaknesses or defects can be identified. This testing ensures that the equipment is capable of withstanding the expected operating pressures and prevents the risk of failure during operation.

The consequences of a pressure vessel failure can be severe, leading to property damage, injury, or even loss of life. Hydrostatic testing provides an opportunity to detect potential leaks or weaknesses before the equipment is put into service, allowing for necessary repairs or replacements to be made. It also helps in meeting regulatory requirements and ensuring compliance with industry standards.

During hydrostatic testing, pressure vessels are filled with water, which serves as the electrolyte for electrochemical corrosion cells. Carbon steel alloys, commonly used in these vessels, are prone to corrosion when exposed to water. Corrosion inhibitors play a crucial role in preventing this corrosion, ensuring the integrity and longevity of the equipment.

Corrosion inhibitors are chemical additives that can be added to the hydro-test fluid to prevent corrosion. They work by forming a protective film on the metal surface, inhibiting the electrochemical reactions that lead to corrosion. By effectively managing corrosion, these inhibitors help extend the lifespan of the equipment and minimize the need for repairs or replacements.

There are various types of corrosion inhibitors used in hydrostatic testing, each with its unique properties and mechanisms of action. Some common types include:

1. Contact Corrosion Inhibitors: These inhibitors form a protective film on the metal surface, creating a barrier between the metal and the corrosive environment. They can be organic or inorganic in nature and are typically safe, non-toxic, and environmentally compliant.
2. Vapor Corrosion Inhibitors (VCI): VCIs are chemicals that volatilize and form a protective vapor phase around the metal surface. They work by adsorbing onto the metal, creating a molecular barrier that inhibits corrosion. VCIs are particularly useful in enclosed spaces or during storage when direct contact with the metal is not possible.
3. Oxygen Scavengers: Oxygen scavengers are chemicals that react with dissolved oxygen in the water, removing it from the system. By reducing the oxygen concentration, these scavengers effectively inhibit corrosion, as oxygen is essential for the formation of rust.
4. Microbial corrosion inhibitors: they are substances that can prevent or reduce the corrosion of metal surfaces caused by microorganisms. They can attach to metal surfaces and form a layer called a biofilm, which can change the chemical and physical properties of the metal and make it more susceptible to corrosion.  One way to mitigate microbial corrosion is using of biocides. Biocides are chemicals that can kill microorganisms. They can be applied to the metal surface or added to the medium where the microorganisms are present. For example, some common biocides used for microbial corrosion inhibition are chlorine, bromine, iodine, quaternary ammonium compounds, and glutaraldehyde.
5. Combination Inhibitors: Some corrosion inhibitors combine multiple mechanisms of action to provide enhanced protection against corrosion. These inhibitors may include contact corrosion inhibitors, VCIs, biocides and oxygen scavengers, offering a comprehensive approach to corrosion prevention.

When selecting corrosion inhibitors for hydrostatic testing, several factors should be considered. These include the water quality, the specific application, and the compatibility with other chemicals used in the system, such as biocides or scale inhibitors. It is important to choose inhibitors that are suitable for the operating conditions and can provide long-term protection.

The inhibitors should be applied according to manufacturer recommendations and local regulatory requirements. The dosage of the inhibitors will depend on factors such as water quality, chloride content, and the desired level of protection. Regular monitoring of inhibitor performance is essential to ensure effectiveness and make any necessary adjustments.

Hydrostatic test corrosion inhibitors are used in different industries:

• Oil and gas industry, for testing and preserving pipelines, valves, vessels, and other equipment that are exposed to corrosive solutions
• Water treatment industry, for testing and protecting boilers, heat exchangers, storage tanks, and other systems that use water or glycol as a medium
