RT, which expert is familiar with the process flow for solvent recovery of aramid 1313? For example, what equipment is needed to achieve solvent recovery? What is the material of the equipment usually? What is used for the inner components?
It seems that the aramid factory also faces many problems regarding solvent recovery. The manufacturer encountered this issue: the dichloromethane distillation column used in solvent distillation was equipped with 316L bulk packing, but within less than a month, all of the packing was gone. But different factories may have different processes, and they encounter different problems as well.
