"Creative" innovation at the grass-roots level in the first line

- Remember Lanzhou petrochemical kettle operation method inventor Qiao Jun
Lanzhou Petrochemical has such an innovative inventor, he invented the kettle cutting method has been included in the "Lanzhou Petrochemical 150,000 tons / year butyl rubber operating procedures", this law for domestic and foreign emulsion polymer rubber production technology also has a strong applicability and a certain promotion value. He is the first-line employee of the butyl rubber device - Qiao Jun.
," Master Joe, the flash tank liquid surface is high! After hearing the recovery staff report when the polymer kettle single kettle was cut out, Qiao Jun commanded the aggregate post operation staff to adjust the discharge pump outlet flow, and resumed the discharge operationafter the liquid surface of the flash tank met the requirements of the process indicators. But not a moment polymerization post staff report, discharge pump outlet pressure is zero, it is estimated that the glue cut out of the polymer kettle has been emptied.
is very wondering, should be an hour and a half to empty the glue, how this time less than 1 hour 20 minutes? It's not going to be the same as the discharge of 55,000 tons/year butyl benzene, is it? With such doubts Joe Jun to check, it is true that the polymer kettle gel blocked the discharge pump inlet pipeline.
Qiao Jun is located in Lanzhou Petrochemical 150,000 tons / year butyl benzene rubber plant has 3 production lines, each production line has 12 polymerized kettles, according to the brand size and production load is different, generally cast 9 to 11 kettles series continuous polymerization, materials in the polymerized kettle for low-forward higher. The goal of polymer kettle single kettle is to realize the rapid adjustment of the production load of the device and to deal with the mechanical seal failure treatment of polymer kettle in a timely manner. In recent years, with the balance of butylene resources in Lanzhou petrochemical rubber plant and the need for butyl rubber custom production brand switching, polymerized kettle single kettle cut in and out increasingly frequent, up to 5 times a month.
On the polymer kettle single kettle cut out, 150,000 tons / year butyl benzene rubber device follows the original 55,000 tons / year butyl benzene rubber device process route, cut out the polymer kettle requires a separate reaction, separate sampling, separate discharge, discharge with discharge pump to the required cut out of the kettle material empty. In the actual operation process, the real reaction in the polymer kettle and whether the material is unloaded can not be accurately grasped, discharge easily caused by process fluctuations. The only difference with the original 55,000 tons / year butyl benzene rubber plant is that Lanzhou Petrochemical 150,000 tons / year polymerized kettle installed polymer kettle remote liquid surface meter, can avoid the phenomenon of polymer kettle discharge is not clean, however, once the liquid surface meter failure, discharge of the specific situation is still unable to judge.
the risk of plant process fluctuations and material emptying during the kettle cutting process occurred at the same time, Qiao Jun thought: "If only the existing conditions can be achieved online discharge." "He looked at the operation of the device and went to the site to figure out the process. In the review of the operation method, when the device system to see the use of nitrogen continuous pressure when the operation, he immediately lit up, if the system parking this operating method can be applied to the single kettle cut out, then the problem is not solved?
days, Qiao Jun checked from the field process to study the existing nitrogen system of the polymer kettle. After hundreds of on-site research and many times to the workshop process personnel, the idea of changing the feed port of the polymer kettle to the feed port gradually formed, and then he carried out practical tests on the device simulation system, and finally theoretically determined the method of on-line cutting of the polymer kettle single kettle.
this operation plan has been put forward on the workshop attention, Lanzhou petrochemical rubber plant agreed to the installation before the maintenance and parking test. Because the kettle test on the polymerization and flash steaming system process almost did not have any impact, cut out the kettle no longer need to take sample analysis alone, but also to achieve the material all pressure empty, the workshop saw its advantages in the actual operation, designated Qiao Jun as the subject leader to improve the operation.
Joe Jun led the team members to carry out repeated research and demonstration on each step of the operation, sum up the experience in the operation time and time again, and finally determine the complete operation method consisting of 13 operational steps, which is also known as the "Joe Jun cut kettle method", won the first prize of the first-line innovation achievements of China's petroleum refining enterprises in 2018.
