While value chain development has become a common buzzword in Iranian petrochemical industry literature, many projects, including MTO and MTP, are still stalled at the raw material sales stage. Petrochemical expert Mohsen Ansari considers “the need for large investments” and “feed instability” to be the most important reasons for the failure of these projects. According to him, in the current situation, the “ethylene” and “propylene” chains have the greatest potential for real completion in Iran and more focus needs to be placed on their development.
