چکیده:

Olefins (ethylene and propylene) are the main building stones for plastics. They can be produced using several processes and feedstocks. For most processes, ethylene is the main output product, followed at a distance by propylene. There are five major processes for producing of olefins; Steam cracking; Olefins recovery from FCC off gasses; Oxidative coupling of natural gas; Biomass (flash) pyrolysis and finally Methanol to olefin(MTO). During the last decade, the demand for propylene has grown rapidly, as an effect of the growing demand for polypropylene. There are several processes for production of olefins via the methanol to olefins (MTO) such as Uop/Hydro, Lurgi and Exxon Mobil. The growing availability of natural gas has led to advances in technologies designed to capitalize on this low cost resources. With Lurgi Mega-Methanol and MTP technology, Lurgi Oel Gas Chemie commands the processes for a complete chain to obtain from natural gas a product with a high value added. Lurgi’s Mega-Methanol technology allows the cost-effective production of methanol and the MTP process ensures the conversion of this product into high-grade propylene.
