What requirements should be considered in the design of tower equipment?

The following should be met: ① High production capacity. It can also operate stably at high mass transfer rates under larger gas and liquid loads or when their fluctuation ranges are wide ； ②Low fluid resistance and low operating costs (this is particularly important in distillation and absorption processes involving materials sensitive to heat and with high volatilities) ； ③It can provide a sufficiently large interphase contact area, enabling mass transfer between the gas and liquid phases under full contact and thus achieving high separation efficiency ； ④To meet the specific requirements arising from the properties of the materials – such as corrosivity, heat sensitivity, tendency to foam, as well as periodic changes in temperature ； ⑤Well-structured, safe and reliable, with low metal consumption and low manufacturing costs ； ⑥Not prone to clogging, easy to operate, and convenient for installation, adjustment, and maintenance ； ⑦Make full use of thermal energy. In summary, tower equipment should meet these requirements to the greatest extent possible, striving to minimize the total cost of the equipment plus the operating expenses (mainly energy consumption) while achieving the specified processing capacity and product purity.
