The olefins ethylene and propylene are two of the most widely produced chemicals in the world and serve as input compounds in a number of polymers and emulsifiers. Crude oil was often used as a raw material in their production; however, in recent years, unstable oil prices along with the growing use of natural gas and coal as raw material sources have driven production from methanol, especially in China.
In order to achieve optimal process yields in MTO plants, the use of gas chromatography is required to monitor trace amounts of components in process fluid including CO, CO2, H2, and various hydrocarbons at various measuring points. Selecting the proper gas chromatographs for this purpose and corresponding treatment processes requires considerable application knowledge and expertise. The team in the Siemens Process Industries and Drives/Process Analytics Division in China, headed by Liu Xiao, has been a valued partner of the MTO industry for many years. With more than ten major projects under their belts, the team, together with proven gas chromatography technology from Siemens, has emerged as a leader in the Chinese MTO sector.
