Abstract
Disclosed is an improved process for the production of a sulfur trioxide conditioning gas, which consists in compensating the faulty 'ambient gas temperature' in a simple and effective manner, such that all of the subsequent functions can take place at the established optimum temperature and can no longer be adversely affected by fluctuations in the ambient air temperature.
