The hydrogen chloride gas is a strong irritant and non-combustible gas, and has strong corrosivity after being dissolved in water. The product is packed in a special high-pressure steel cylinder and is in a liquid state. The special steel cylinder is a steel seamless gas cylinder, and the inside of the steel cylinder is polished. The bottle valve is a corrosion-resistant stainless steel diaphragm valve. Currently, there are two main types of hydrogen bromide charges: firstly, the filling is carried out by pressurizing through a pump or a compressor, and secondly, the filling is carried out by heating, raising the temperature and vaporizing.
The first filling method has the following problems: (1) the use of a pressurizing device (a pump or a compressor) is increased, and the risk of hydrogen chloride leakage is increased while the equipment investment is increased; (2) during the use of the pressurizing device, the temperature of the hydrogen chloride is also increased, and the corrosiveness of the hydrogen chloride is increased. The second filling method has the following problems: (1) when filling the dress through heating to step up, it is higher to the control requirement of temperature, and high temperature high pressure can improve the corrosivity of hydrogen chloride simultaneously, and the risk is revealed in the increase, reduces the life of equipment and pipeline.
