Hydrochloric acid (HCL)

Hydrochloric acid gas is a colorless gas with a pungent, acidic odor and is heavier than air. It readily liquefies to form a colorless liquid and, in a wet or dissolved state, turns a blue substance red. It combines with metals, metal oxides and their hydroxides and has a density of 1.18 g/cm3.

Applications

• Hydrochloric acid is used in oil well acidification, boiler scale removal, urea reduction, and as a chemical intermediate. Other applications include steel washing, organic compound manufacturing, inorganic compound production, pH control and neutralization, ion exchanger regeneration, leather polishing, household cleaners, and the construction industry.

Maintenance risk

• The very low pH of this acid makes it highly corrosive. The chemical produces toxic gases that can damage equipment and pose a fatal hazard to workers. Controlling the gas from hydrochloric acid requires a precise system for tank venting. This corrosive, acidic liquid is extremely corrosive and its storage is a significant challenge. Due to the release of these gases, tank maintenance is a major concern. Tank entry should not be attempted under any circumstances and replacement parts should be kept to a minimum.

Maintenance method in plastonic tanks

• The storage of highly corrosive hydrochloric acid and its toxic vapors requires a special system that solves these problems by producing strong and corrosion-resistant tanks.
• The tank should be installed on a smooth and flat concrete, asphalt or steel surface. No ropes or devices should be used to secure the tank around it, and ladders should not be connected to the tank.
• The temperature of transportation and storage according to the standard should not exceed 37 degrees Celsius.
• The material of the connections used in the tanks for storing this material is polyethylene and polyvinyl chloride, and gaskets made of ethylene propylene diene monomer are used for sealing.
