Qilu Petrochemical Olefin Plant realizes gas-phase ethylene direct supply

The propylene refrigeration compressor GB501 is the core of the ethylene plant, and whether the operation is stable is the key to determining whether the high production of ethylene can be achiev.

Last year, the propylene refrigeration compressor GB501 had the problem of excessive shaft displaceme.

Through a series of optimization measures, the axial displacement of the propylene refrigeration compressor GB501 has been effectively controlled, but there are still potential safety hazards during high-load producti.

Since the beginning of this year, in order to increase the output of ethylene, the ethylene plant of the olefin plant is in the stage of high-load producti.

In order to ensure the smooth operation of the ethylene plant of the olefin plant, realize the long-term stable operation of GB501, and prevent the plant from shutting down due to the failure of the compressor system, they brainstormed and found solutio.

The olefin factory and the plastics factory are actively negotiating and discussing whether the system can be reformed to reduce the load of the propylene refrigeration compress.

"Through the transformation, gas-phase ethylene is directly supplied to the plastics plant to reduce the production load of GB501, which is an effective measure to solve the stable operation of the propylene refrigeration compress.

At the end of August, the olefin plant's gas-phase ethylene direct supply plastic plant reconstruction project was officially approv.

On October 4th, the prefabrication of the construction pipeline outside the factory was completed, and then the on-site construction phase in the factory beg.

On October 13th, the construction of the gas-phase ethylene direct supply project was completed, and they immediately carried out follow-up inspections, three inspections and four determinations to ensure that there were no problems with the construction quali.

On October 14, the construction of one side of the plastics factory was completed, and the two factories immediately started the preparatory work before putting into operati.

On October 15th, the cracking workshop of the olefin plant replaced the pipeline, and the equipment was basically ready for operati.
