Simulation of VOCs Adsorption Energy Storage Module for Ship Based on Aspen Adsorption
In order to control the unorganized VOCs emissions generated during the painting process of marine painting industry in outdoor venues such as shipyards and wharfs,a VOCs mobile adsorption energy storage mod-ule with a processing capacity of 2000 m3/h was designed to solve the problem of unorganized VOCs emissions in outdoor environment.At the same time,Aspen Adsorption software is used to simulate the longest working time and processing efficiency of VOCs mobile energy storage module in a single cycle according to the properties of adsorbent.The penetration curve is obtained,and the amount of organic matter that can be stored by a single ener-gy storage module is calculated.The results showed that when the VOCs adsorption energy storage module was loaded with 2.2 m3 adsorbent,the adsorption time of up to 40 hours could be satisfied under the intake conditions of 2000 m3/h and 300 mg/m3,and the adsorption efficiency was guaranteed to be above 96%.Each cubic adsor-bent can absorb about 12.5 kg of VOCs.Each energy storage module can store about 26.26 kg of VOCs after ad-sorption and saturation,and can provide 9.729×105 kJ energy after desorption and combustion.The VOCs mobile adsorption energy storage module can cope with the disorganized emissions generated by the ship painting field,and can provide energy for the regenerative oxidation furnace RTO,reducing the energy consumption during RTO operation.
