Abstract

The invention provides a bis(fluorosulfonyl)imide impurity removal and purification system and a bis(fluorosulfonyl)imide impurity removal and purification method. The system comprises a light-component stripping tank, a gas-liquid separator, a product buffer tank, an impurity removal reactor, and a film evaporator. The light-component stripping tank is connected to a reaction product liquid supply source. The gas-liquid separator is connected to the light-component stripping tank and also connected to the light-component product recovery device. The product buffer tank is connected to the light-component stripping tank and also connected to the gas-liquid separator. The impurity removal reactor is connected to the product buffer tank and also connected to an impurity removal reactant supply source. The film evaporator is connected to the impurity removal reactor, connected to a gas-phase separation system, and also connected to an impurity collection tank. The bis(fluorosulfonyl)imide impurity removal and purification system and the bis(fluorosulfonyl)imide impurity removal and purification method according to the invention make it possible to remove impurities from bis(fluorosulfonyl)imide continuously and efficiently and purify it.
