How to Store Hydrogen Chloride Aqueous Solution Safely
As we all know, hydrogen chloride is a colorless gas, and has a strong irritating odor. It also has an important characteristic that it is soluble in water. The hydrochloric acid is actually the aqueous solution of hydrogen chloride, because its aqueous solution is acidic, called chloric acid, which is commonly called hydrochloric acid. So how to store hydrogen chloride solution safely in real life? Now let's give you a detailed introduction.
For high purity hydrogen chloride, it is usually stored in a cool, ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30 C. It should be stored separately from alkali and active metal powder. Mixed storage should not be avoided. The storage area should be equipped with emergency leak handling equipment.
The main points for attention in the operation of high purity hydrogen chloride gas are: tight closure, adequate local ventilation and comprehensive ventilation. Operators must be specially trained to strictly comply with the hydrogen chloride operating procedures. Operators are advised to wear filtered gas masks (half masks), chemical safety glasses, chemical protective clothing and rubber gloves.
Of course, hydrogen chloride products in the storage process also need to avoid smoke, prevent gas leakage to the workplace air, avoid contact with alkali, reactive metal powder. Particular attention should be paid to avoiding contact with water. Light loading and unloading during handling to prevent cylinders and accessories from being damaged. Equipped with leak emergency treatment equipment.
For hydrochloric acid in aqueous solution of hydrogen chloride, its storage tank should be placed in a base made of cement bricks. The base height is generally half of the tank body. Put the hydrochloric acid tank body in the place of use, then fill it with brick cement, and pay attention to the sand filling on the contact surface between the barrel and the brick. After the cement brick foundation is fully solidified, the material is put into use.
Because some full plastic flanges of hydrochloric acid storage tanks are softer than steel plates, attention should be paid to strengthening when connecting with other flanges. Users should check the sealing performance of anti-corrosion storage tanks before using, and liquid can be added to observe whether leakage occurs. When the inlet of the hydrochloric acid tank is higher than the bottom of the tank, the inlet should bend to the tank wall to let the incoming liquid fall down along the tank wall to reduce the impact on the bottom. If the level of the hydrochloric acid tank can not be controlled, the overflow outlet should be installed on the hydrochloric acid tank in order to prevent the overflow of the liquid and cause unnecessary damage.
Hydrogen chloride manufacturer is the largest hydrogen chloride supply base in Zibo area. Its high-purity hydrogen chloride gas is of high quality and reasonable price. It is welcomed by downstream demand manufacturers and is trustworthy.
