Ethylene plant in China the first time in a row 3 in the senior cycle, overload, stable operation of the target . PetroChina Lanzhou,[link widoczny dla zalogowanych], the recent large-scale ethylene plant will be replaced with the inhibitor of imported products, which marked the high pressure off the domestic super-versatile propane tower inhibitor technology has matured, product quality has reached international advanced level. Allegedly,[link widoczny dla zalogowanych], BI inhibitor of a 628B with a strong ability to capture the activity of free radicals, the dosage of inhibitors of traditional 3o ~ 5o double olefin polymerization can be inhibited, slowing the pressure off the propane ethylene tower and reboiler fouling speed, extending the device operation cycle . And the product in the production process without waste, no pollution, is a typical environment-friendly products and cost-effective. Currently, foreign multi-function ethylene plant by using powerful inhibitor. Cycle has reached its maximum of 5 years running,[link widoczny dla zalogowanych], but the domestic ethylene plant are generally carried out every year maintenance shutdown. ABB Lummus process used by the US Central Plains petrochemical company 180kt / a ethylene unit in the selection of BI 2005, a 628B inhibitor, and then overload continuous and stable operation of the device for more than 3 years, annual output device over 2l0kt. June 2008. The ethylene plant for big overhaul, E-DA404N tray tower and the tower tank were very clean, in this free maintenance during the cleaning, EA reboiler operation cycle of a 464N also extended from the previous 5 months to 11 months, and the amount of inhibitor saving at least 35.3 years of actual operation results show that high pressure off the propane tower and reboiler inhibitor with satisfactory results. [China Petrochemical Science and Technology Information Center station of organic material feed] Evonik Industries MMA company successfully developed a new technology in Germany Evonik Industries has successfully developed a hydrogen based on the traditional acetone alcohol (ACH) route of the new methyl methacrylate ester (MMA) process, the process avoids the production of heavy ammonium sulfate by-product generation. According to Evonik's Performance Polymers business leader GregorHetzke said: \ catalyst to replace the traditional ACH process for sulfuric acid. Does not require new processes for recycling of sulfuric acid, so you can save a lot of cost. ACH in the traditional process,[link widoczny dla zalogowanych], sulfuric acid recovery unit occupies the entire MMA larger portion of investment costs, but also takes up the whole unit energy consumption of about half. Aveneer new technology can be applied to new devices, but also can be used in the transformation of existing legacy devices. The first set of commercial use Aveneer MMA device process will begin in 2009 part of the work based project is expected to put into operation in 2012.
