The transportation of the cracking gas compressor oil for the ethylene plant in Tarim’s 1.2 million tons per year Phase II ethylene project was successfully completed

Thread Content

The oil circulation process for the pyrolysis gas compressor in the ethylene plant of Tarim’s 1.2 million tons/year Phase II ethylene project was successfully completed. Recently, at the construction site of this project, the final flushing step of the oil circulation system for the pyrolysis gas compressor was finished successfully, marking the end of the flushing process for the \"blood system\" of this vital equipment in the ethylene plant. The pyrolysis gas compressor is regarded as the \"heart\" of the ethylene plant; its stable operation is directly related to the safe, stable, long-term, efficient operation of the entire plant. During the air testing phase, it also provides sufficient compressed air for the purging of the plant’s pipeline system. The lubrication system is the \"lifeblood\" that ensures the smooth operation of the compressor. The oil transportation process aims to thoroughly remove mechanical impurities such as rust, slag, and oxide scale from within pipes and equipment through the circulation and flushing of lubricating oil, ensuring that the oil meets extremely high cleanliness standards. This provides optimal lubrication and protection for the bearings of the low/mid/high-pressure cylinders, gearbox bearings, main motor bearings, and the top shaft oil system, thereby preventing damage to the equipment during operation. This oil transportation task involved 20 days of round-the-clock efforts, facing multiple challenges such as complex system processes, high requirements for flushing precision, and long circulation cycles. To ensure the success of the oil transportation operation from the very beginning, the project team adhered to the principle of \"starting with high standards and advancing with strict requirements,\" and carefully prepared a detailed oil transportation plan as well as emergency response plans. For this critical aspect of pipeline cleaning, the project team adopted an innovative collaborative approach that combines professional external cleaning services with efficient on-site installation, ensuring that the pipeline cleaning is carried out efficiently and to a high standard, thus enabling seamless continuation of the project timeline. The operation tests of 6 electric heaters were completed simultaneously to ensure stable equipment performance. The project leader is in charge, with management staff and operators working in shifts to coordinate and resolve any issues that may arise during oil transportation, ensuring everything runs smoothly. By comparing the results of 31 filter cleaning inspections, the effectiveness of oil transportation can be accurately assessed, allowing for timely optimization of operational procedures.
