Feasibility of designing double-layer liquid chlorine storage tanks at low temperature and normal pressure
Thread Content
In recent years, various safety standard specifications such as those for personal and social risk analysis have been introduced. As a result, the impact area of accidents involving existing pressurized liquid chlorine storage tanks is quite large, typically ranging from 1 to 2 kilometers. According to accident simulation calculations, pressure is one of the main factors contributing to this large impact area, which significantly affects the layout and overall design of enterprises that use liquid chlorine. To address this issue, we invite everyone to contribute their ideas and discuss the possibility of designing liquid chlorine storage tanks as double-layer tanks operating at low temperatures and under normal pressure. Given the corrosive nature of liquid chlorine and other associated hazards, it is important to prevent more serious safety accidents due to improper design; therefore, it is necessary to consider what key safety features should be included in such tanks...
It’s been a year, and no one has responded to the original poster’s post. Personally, I think this is a good approach. There are now many designs for low-temperature, normal-pressure tanks using liquid ammonia, but none have been seen for liquid chlorine yet. Since liquid chlorine is a highly toxic chemical, a double-layer fully sealed tank must be used in designs operating at low temperature and normal pressure.

Recently, I came across a company that, due to safety concerns related to temperature, designed its liquid chlorine storage tanks as low-temperature tanks in order to control the storage temperature – thereby reducing the saturated vapor pressure. This problem was solved… though it meant higher investment in safety measures
