In order to better share and discuss knowledge and skills with everyone, I would like to apply to become a “Technical Discusser” – as a challenge for myself as well! As required, a dedicated thread for answering questions has been created. My areas of expertise include the basic operations and accident analysis related to the ethylbenzene unit and the styrene unit (primarily the processes for producing ethylbenzene from dry gas and the styrene production process). I have over 7 years of experience in working with styrene. I will definitely do my best to answer any questions raised! Online time: 3-4 hours per day on average, or even longer! Note: H8 z6 v$ `$ L! N9 ~4 g 1) This post focuses on issues related to the operation of styrene and ethylbenzene processes as well as accident analysis, aiming for mutual exchange and joint improvement. This post is intended for one-on-one discussions between those seeking help and me; other users are also welcome to join the discussion. If you are not satisfied with the responses, please create a new topic under Deep Processing of Petrochemical Products. Thank you for your cooperation! 5 d/ r, w/ K- v }+ l, z$ A" V 2) Due to work commitments, I may not be able to respond promptly; please understand (but it will never take more than 2 days).
