Yanhua MTBE production system was patented

　　Recently, the "a methyl tertiary butyl ether (MTBE) production system" applied by Yan'an Petrochemical Plant of Shaanxi Yanchang Petroleum (Group) Co.
, Ltd.
has been granted a utility model patent by the State Intellectual Property Office
.
The patent has been applied in practice
.

　　In the past, the MTBE unit of Yanhua Light Hydrocarbon Center used the traditional process of start-up
.
In the actual production process of this process, it is easy to cause problems such as over-temperature and over-pressure of the device, reduction of the service life of the catalyst, and large energy consumption of the device materials, which affects the normal production of the product
.

　　To this end, the factory's technicians actively optimized the operation, summarized and refined "an MTBE production system", adjusted the original start-up process to a "reverse start" process, and added two additional lines on the basis of the original process
.
"Before feeding, let the methanol extraction tower and methanol recovery tower circulate, take away excess methanol across the line, and then reduce the load of the methanol recovery system during the start-up process, and finally start the etherification reactor, introduce raw materials, and connect the whole process.
One-time production of qualified products
.
" said Xie Yangyang, a technician
.

　　It is understood that this process makes the etherification reaction more thorough, the separation effect of the catalytic distillation column is more complete, solves the problem of excess methanol recovery generated by soaking and rinsing the catalyst in the reaction system, and achieves the purpose of successful start-up in a short time, and the safety production work of the plant is solved.
The development and improvement of economic benefits are of great significance
