The inspection device of Qilu Rubber Plant was transferred to normal production

China Petroleum & Chemical News.

On September 27, an extraction unit in the rubber factory was successfully started up

Grain and grass first, make good material reserves

"We test pumps and prepare materials in advance according to the maintenance process and start-up time of the device, so

The workshop carried out cyclic trial operation in advance of the 21 pumps that were rebuilt and inspected, prepared for the storage of incoming materials, and focused on carbon four blending for start-up production of acetonitrile and an extraction device

From September 5th, we started to unload the purchased butadiene, and on the 8th, we started to unload the C4

"In the early stage, butadiene was received and there was no frozen brine.

From September 5th, the workshop began to store butadiene and unloaded 20 trucks of 540 tons per day.

Resolutely, get through the driving process

　　At 10 o'clock on the 13th, a styrene-butadiene plant was put into operation.

　　"After the equipment is overhauled and delivered, the technicians will focus on the air tightness test, penetration test, moving equipment spot test, equipment interlocking and process interlocking debugging of the ammonia refrigeration system according to the division of labor

　　The spot test work of 248 moving equipment requires the cooperation of 3 people to complete.

　　"Because the polymerization reaction requires high oxygen content in the system, a single device must be cut off for nitrogen replacement before starting up, so that the oxygen content is controlled below 0.

　　After nitrogen replacement, the normal production process needs to be restored to pump negative pressure, all the valves in the system are opened for butadiene replacement, and then changed to the feeding process after replacement

　　Hand in hand, latex is the first to leave the factory

　　In order to ensure a successful start-up, the molding workshop intensively organized stand-alone test runs, instrument joint calibration, pressure test and leak testing, equipment cleaning, etc.

　　"The driving conditions are ready, feed the materials immediately

　　At 17:00, the first rubber product was sent to the conveyor belt, and the molding workshop drove successfully

　　Liquid latex is an intermediate product of rubber production.

　　"In the early stage of the installation, communicate with the production technology department and workshop in a timely manner, grasp the production situation of latex, feedback the information to the Qilu business department and customers of the North China Branch of Chemical Marketing, and make preparations for loading and leaving the factory
.
" Technical team leader of the storage and transportation workshop Zhang Lixin said
.

　　On September 16, 8 vehicles of liquid latex products were the first to be shipped.
As of the 23rd, a total of 1,333.
64 tons of latex had been shipped
.

　　At present, the rubber plant has realized that the device can be opened stably.
It has produced three grades of butadiene rubber and styrene butadiene rubber rubber products, and is striding forward to the stable operation of the device under high load
