At 10:05 on April 16, the hexene-1 workshop of the Second Daqing Petrochemical Chemical Plant started four catalyst pumps A, B, C, and D in sequence as planned.
The polymerization reaction in the reactor proceeded smoothly under the action of the catalyst.
The temperature and pressure are controlled within the range of indicators, marking the successful completion of the hexene-1 unit into operation
.
? The hexene-1 plant received a start-up task after a shutdown period of more than 6 months
.
Due to the long downtime of the device and just going through the winter, the second chemical plant and workshop attached great importance to the start
.
Since receiving the start order, they have started careful deployment, actively coordinated, and tracked the list of various operations
.
Blind boards for public works and raw vinyl lines in the boundary area were removed
.
And make a record
.
Contact Industrial Company in advance of catalyst required to complete the device configuration, and on-site service time to complete the A, B, C, D configuration of the work of four catalysts
.
Send the original 21 tons of stock cyclohexane solvent to the T201 tower for drying operation and dehydration to ensure that the water content in the system is within the qualified index range
.
Organize and complete the commissioning of all interlocking devices and regulating valves
.
The nitrogen replacement work of the catalyst unit, reaction unit and rectification unit of the device was completed ahead of schedule, and the dew point of the system and the oxygen in the nitrogen were all tested and analyzed
.
Strictly control the process operation flow and strictly control the ethylene replacement of the reactor to ensure that the reactor replacement is qualified.
Before the device is officially started, the rectification system flow should be opened to strictly check the leakage points on the spot
.
Immediately after the start of the device, personnel were organized to perform on-site timing calibration of the catalyst, cyclohexane, and terminator.
The main operation and inspections were closely coordinated, and various instructions were accurately completed through the on-site walkie-talkie
.
The main operator performs the metering adjustment of the catalyst in time according to the measurement result to ensure the good polymerization reaction effect of the device
