MTO (Methanol to Olefins）and MTP (Methanol to Propylene) are two new important processes for methane chemical industry.  It is a chemical technology, using methanol synthesized from coal or natural gas as raw material, with a fluidized bed reaction which is similar to catalytic cracking unit, producing low carbon olefins. The cryogenic separation section of olefin separation uses a multi - stream cold box.

Zhongtai supplied MTO cold boxes for Ningbo Heyuan 300,000 ton polypropylene and 500,000 ton glycol project, Wison Nanjing 250,000 ton butyl alcohol project and Shandong Yangmei Hengtong 300,000 ton DMTO project. Cold boxes are operating well.
