On August 23, Baotou Chemical, following the principle of producing goods based on demand and switching to different product grades as needed, and taking into account the operating conditions of the reactors, organized its employees to carry out this online conversion. By gradually reducing the amount of butylene added and increasing the amount of hydrogen added in advance, it was possible to shorten the time required for the grade switch. A standardized operating procedure was strictly followed, with employees instructed to carry out the conversion step by step, in accordance with established protocols and standards. This approach helped to prevent significant fluctuations in production due to operational errors, thus laying a solid foundation for completing this grade conversion efficiently, with high quality and at a high level.
