On October 30, the country's first propane gas monomer oven for the DMTO unit of the Olefin Plant of Qinghai Damei Coal Company was completed, which played a key role in the smooth advancement of preparations for the next start-up. This oven uses two oven methods: electric drying and gas drying. Gas drying is the first example of a single oven in the country. It is also the first nationwide demonstration project to use propane gas for drying. The oven team is composed of factory leaders, process, equipment, safety, duty personnel and corresponding device team members. On September 20, the electric drying work of the DMTO device and the combined device officially started. On October 2, the gas drying work officially started as planned. On October 30, with the completion of the cooling of the DMTO reactor lining, the gas drying work came to a successful conclusion. The propane monomer drying furnace adopted new technologies, new methods, and new ideas. At the same time, it also faced the characteristics of heavy tasks, high requirements, and many difficulties. During the implementation of specific measures, the drying team focused on the characteristics of low-temperature condensation and high combustion value of propane, and did a good job in insulating and tracing system pipelines and adding linings to the dryer outlet pipelines and radiation chambers. They solved problems, overcame difficulties, and completed the drying and lining tasks with high standards.
