Anti-Corrosive Industrial Coatings

Why? - Anti Corrosive PAINT Technology for Ammonia Plant By : Automotive Solutions
Anhydrous Ammonia (NH₃) is commonly used as a coolant in large industrial refrigeration systems. While ammonia refrigeration has long been a standard in the food / beverage industry, it is also now found in pharmaceuticals production, in air-conditioning equipment for some public buildings and in electric power generation plants. Ammonia is a toxic gas, though, and the proper safety monitoring procedures and equipment must be in place at all times to avoid serious accidental injury or death…

Ammonia refrigeration is considered cost efficient, and has been credited with keeping the price of food at affordable levels in the U.S. It also plays a role in the floral industry, as well as in various types of cold storage warehouses and in ice production. Ammonia industry experts say its use in refrigeration systems is environmentally friendly, and it does not destroy ozone or contribute to the greenhouse effect linked to global warming.

A major problem in the process industry is the corrosion of metals in pipes, valves and other parts of the equipment constructions. This write up indicates acceptable combinations of more or less aggressive fluids and commonly used materials like ammonia.

What is Ammonia
Ammonia (NH 3) is one of the most commonly produced industrial chemicals. It is used in industry and commerce, and also exists naturally in humans and in the environment. Ammonia is essential for many biological processes and serves as a precursor for amino acid and nucleotide synthesis. In the environment, ammonia is part of the nitrogen cycle and is produced in soil from bacterial processes. Ammonia is also produced naturally from decomposition of organic matter, including plants, animals and animal wastes

Some chemical/physical properties of ammonia are:

At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor In pure form, it is known as anhydrous ammonia and is hygroscopic (readily absorbs moisture) Ammonia has alkaline properties and is corrosive Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. Ammonia gas is easily compressed and forms a clear liquid under pressure. Ammonia is usually shipped as a compressed liquid in steel containers. Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.

Exposure Risks – Ammonia
Reliable ammonia detection ensures both personnel safety and product quality. The nose may detect ammonia in concentrations as low as 5 ppm. Typical exposure symptoms are irritation of the eyes, throat and respiratory organs. At a few hundred ppm, irritation of the mucous membrane of the eyes occurs. Breathing is intolerable at about 1000 ppm and vision may be impaired. The risk of fatality rapidly increases at concentrations of around 2500 ppm.

In addition to personal injury, ammonia accidents can result in considerable equipment, materials, product and property losses. According to the EPA and Factory Mutual, ammonia releases have resulted in several catastrophic losses ranging up to several million dollars. Such losses have resulted from ammonia contamination to product, as well as explosions because ammonia is potentially combustible.

Ammonia Leak Can Be Due To Corrosion
Because ammonia may cause an explosion when mixed with air, proper safe guards should be taken to minimize accidental release of the gas. Leaks create a serious fire and life safety hazard. Leaks also be caused by:

Pipe failure due to electrolytic corrosion between dissimilar metals.
Materials of construction for ammonia are dependent on the operating temperature. Whilst mild steel may be used at ambient temperature special steels are required at low temperatures to avoid embitterment. Impurities in liquid ammonia such as air or carbon dioxide can cause stress corrosion cracking of mild steel. Ammonia is highly corrosive towards copper and zinc.

Therefore Selection of Right System for Paint is necessary to avoid corrosion between dissimilar metals.

Safe Exposure Levels - Ammonia
The Occupational Safety & Health Administration (OSHA) has set a limit of 25 parts-permillion (ppm) in the workplace during an 8-hour shift and a short-term limit (15 minutes) of 35 ppm. International standards for ammonia exposure are similar to those in the U.S. The effects of ammonia exposure range from irritating smells to life-threatening situations.

The Environmental Protection Agency (EPA) regulates ammonia under the Clean Air Act’s General Duty Clause [Section 112(r)(I)] and Risk Management Program (RMP) Rule [40 CFR 68]. Facilities with over 10,000 pounds of ammonia are required to develop a hazard assessment, a prevention program, an emergency response program and submit a risk management plan to the EPA.

Copper Corrosion is the degradation of metal caused by a reaction with the environment, such as oxidation and chemical attack of the metallic surface. Copper is susceptible to attack from sulfur-containing gases. The result is the formation of a nonproductive layer on the material surface. Unprotected copper tubing will continue to react with the contaminant and corrode. Under severe, prolonged conditions, the copper tubing continues to corrode until the integrity of the equipment is jeopardized. Unprotected copper in polluted industrial environments can lead to failure of the refrigeration system. Sulfur- and nitrogen-based electrolytes are often the cause of accelerated corrosion in industrial environments.
