Zusammenfassung:The invention provides a full-desorption process for treating impurity-containing byproduct hydrochloric acid. The full-desorption process comprises the following steps: S10, a first desorption process; S20, a negative pressure dehydration process; S30, an impurity removal process; S40, a second desorption process; and S50, an entrainer concentration process. The full-desorption process for treating impurity-containing byproduct hydrochloric acid is provided with two desorption processes, the negative pressure dehydration process and the entrainer concentration process are configured; after the two desorption processes are combined, the two desorption processes can be used independently or cooperatively according to the influence of environmental conditions; when the desorption processes are used in cooperation with the method, the defects that some impurity-containing byproduct hydrochloric acid cannot be subjected to conventional full-analysis treatment and conventional full-analysistreatment is high in ene
