If the sulfuric acid content in the finished chlorosulfonic acid is too high, how can this be resolved?

The quality of the chlorosulfonic acid products manufactured by our company never improves; it remains between 95% and 96%, with a sulfuric acid content of over 3.0%. Could some experienced colleagues suggest ways to solve this issue? How to reduce the sulfuric acid content. The problem emerged in recent days; production had been normal before, with the purity of the chlorosulfonic acid product remaining between 97% and 98%. Sulfuric acid content between 1.5 and 2.1: handshake
It is generally caused by a high moisture content in hydrogen chloride gas, and sometimes it is caused by a high level of acid mist in sulfur trioxide gas.
I wonder if there are any other reasons?
Reply to 3# Jiumen Tidu: Generally, one first analyzes the moisture content in hydrogen chloride gas, which is relatively simple; then, the results are compared with previous analysis data to determine if there are any fluctuations. The method for analyzing moisture in gas can be based on that used for analyzing moisture in gases produced in sulfuric acid production.
Thank you, really grateful. Well, it’s true that the moisture content is too high
