液氨是低压液化气体,通常用气瓶运输和贮存。气瓶是流动性压力容器,掌握其安全技术,对于压力容器管理和化工生产操作都是至关重要的。 1.液氨充装系数的确定 从理论上讲,低压液化气钢瓶的充装量等于30℃时气体的液相密度和钢瓶容积的乘积。一般情况下,正确使用时瓶内介质的温度 Liquid ammonia is a low-pressure liquefied gas, usually transported and stored in cylinders. Gas cylinders are fluid pressure vessels, mastering their safety technology, and are vital for both pressure vessel management and chemical production operations. 1. Determination of filling factor of liquid ammonia Theoretically, the filling amount of LPG cylinders is equal to the product of gas phase density and cylinder volume at 30 ℃. Under normal circumstances, the correct use of the media temperature inside the bottle
