Operating conditions: medium flow rate of 1200 kg/h, equivalent to a flow rate of 650 Nm3/h; inlet gas temperature of 50°C; inlet gas pressure of 3–5 kPa; HF content of 700 ppm. It is required to use a scrubber tower to wash hydrogen fluoride; the material of the scrubber tower should be PP, and the packing can be regular plastic corrugated plates or bulk packings such as Pall rings. The hydrogen fluoride content in the raw gas after washing is no more than 1 ppm. Since hydrogen fluoride reacts with water to form hydrofluoric acid and aqua regia, which are deadly to subsequent equipment, the lower this concentration, the better; ideally, it should be at the PPB level.
