Anti-Corrosive Industrial Coatings

Anti-Corrosive Industrial Coatings

Introduction:

Anhydrous Ammonia NH3 is a popular coolant used in different types of industrial refrigeration systems. For many years now, ammonia refrigeration had been considered as the standard in variety of food and beverage industry. It is also being used in recent times in different types of air-conditioning equipment, electric power plants, and pharmaceutical industries. Besides, Ammonia is also used in cold storage ware-houses, floral industry and large industrial plants. 

 It is important to note that Ammonia is a lethal gas and if proper safety and monitoring procedures or equipment is not available, hazardous effects are bound to happen. Experts say that there is extensive use of NH3 as refrigerants is friendly to your environment, and will destroy the ozone or have any role to play in the greenhouse gas. However, Ammonia causes metallic corrosion in the valves, pipes and different types of equipment used in construction.

Structure of Ammonia

Ammonia or NH3 is quite in demand industrial chemicals that are extensively used in different types of industries and commerce. In natural form, Ammonia is known to exist in the humans as well as the environment around us. NH3 plays critical role in different types of biological processes, nucleotide synthesis and amino acid synthesis. In soli NH3 is one of the products bacteria. Organic matter after decomposing gives bacteria.  NH3 is also the part of decomposition of different types of organic matter.

Ammonia & Its Attributes

·         Ammonia is not very highly flammable. However, Ammonia containers can easily explode on high exposure to heat.

·         Shipped for long distances in the form of liquid in steel containers.

·         Ammonia gas under pressure becomes cooled liquid.

·         On dissolving in water, Ammonia dissolves to form Ammonium Hydroxide, NH3 (OH). The NH3 (OH) is a caustic solution and shows poor base qualities.

·         Ammonia is corrosive in nature and it has alkaline properties.

·         Ammonia is a gas with suffocating odor and pungent smell at room temperature.

·         In its purest form, Ammonia is Anhydrous Ammonia and it readily absorbs high moisture content.

Risks Associated with Ammonia Exposure

On exposure to Ammonia, individuals may tend to suffer from the eyes irritation, besides irritation to respiratory and throat organs. Ammonia with few hundreds ppm, there is very high possibility of irritation in the eye’s mucous membrane. At around 1000ppm of Ammonia, human vision might be seriously affected. Furthermore, the high risk of fatality will double at 2500 ppm.

 

Furthermore, ammonia accidents in industrial units can result into severe damage to equipment, property loss, and material loss. In many cases, Ammonia Explosions have also resulted causing serious material as well as human loses. It is quite significant to note that Ammonia has high combustible value.

Corrosion Causes Ammonia Leak

Proper safety is always required when storing Ammonia as the gas can easily explode on mixing with air. Efforts should be made to minimize the accidental release of the Ammonia gas. Ammonia can also leak easily from the pipes that burst due to the electrolytic corrosion.

Ammonia also shows strong corrosive nature with copper and zinc. Ammonia can be stores in specialized steel containers at low temperatures. This will help in avoiding the embitterment.  Mild steel can be easily cracked due to presence of carbon dioxide or other types of impurities.

Ammonia leak is a common problem in the Beverage Bottling Industry, Foods & Snack Industries, Meat Packing Industry, Confectionaries, Dairies & Creameries, Produce and several more.

What are the Minimum Safety Exposures of Ammonia?

The Occupational Safety & Health Administration (OSHA) Limit:

 25 parts-per-million (ppm) for 8-hours shift and a short-term limit (15 minutes) of 35 ppm

International standards for ammonia exposure show the synch with those in US. There are harmful effects of Ammonia and include irritation and other important factors.

The Environmental Protection Agency (EPA) controls ammonia in the Clean Air Act & General Duty Clause [Section 112(r)(I)] and Risk Management Program (RMP) Rule [40 CFR 68]. Factory and work areas showing over 10,000 pounds of ammonia need a hazard assessment, a prevention program, besides a contingency program. Such factory and work areas need to give emergency response program and submit a risk management plan to the EPA.

   

Automotive Solutions: Anti-Corrosive PAINT Technology for Ammonia Plant

Research shows that Nitro Cellulose and/or Synthetic Enamel Paints are efficiently used for protection against the rust. However, the real facts are that these tardy paints do not provide any kind of UV Resistance, Chemical Resistance or for that matter any kind of protection from the environmental damages.

It is for this reason that industries and factories require solid and high quality coating.  Automotive Solutions is an experienced paint solutions company offering innovative anti corrosive paint systems that will provide foolproof protection against all types of corrosion resistance.  At Automotive Solutions, we have 3 Coats and 5 Coats System. We also have state of art rust preventive coatings for implementation to any of the areas. We have the expert team that has experience in offering innovative Ammonia Plants Auto Corrosive Coatings in different parts of the country like Delhi, Noida, Gurgaon, Punjab, Haryana, and Faridabad.
