Suitable tray numbers of various towers are as follows:absorber 46,deabsorber 43,stabilizer 40 and reabsorber 14.Beyond these limits,the energy consumption and investment will add with little effect on the global profits.

• 塔板数也并非愈多愈好 ,各塔的板数不宜超过以下限度 :吸收塔 46块 ,解吸塔 43块 ,稳定塔 40块 ,再吸收塔 14块。 超过此限 ,对总体经济效益的影响很小 ,但增加了能耗和投资。
