Large drying system modification for energy-saving
Chunwang Yi, Mancai Xu · Xiandai huagong · 2005
Large drying systems in polymer plants in China have had problems in general in design.For example,the electricity consumption of the first blower was too high,the drying ability was not enough for the nitrogen because of too quickly decreasing of water-absorbing ability during the recycling process,the heat energy of nitrogen couldn't be exchanged.To overcome the shortcomings above,the drying system was modified,including a new type of dehydrator used,a new drying tower with two sections adopted,the watt of the first blower lowered,and a heat-exchanger added.
