Lanzhou Petrochemical’s 80,000 Tons/Year Acrylic Acid Plant Output Hit A New High

At the end of November, the author learned from the Fertilizer Plant of Lanzhou Petrochemical Company that the single-day output of the 80,000 tons/year acrylic acid plant of Lanzhou Petrochemical reached 276 tons, breaking the daily production record for 13 years since the plant was put into operation.

Since the third quarter, the Lanzhou Petrochemical Fertilizer Plant has steadily and deeply organized technical research. While implementing epidemic prevention and control measures, it has implemented the process optimization of the acrylic acid plant reactor, the recycle gas modification, and the optimization of the start-up line as planned to provide for the high-load operation of the plant. Technical support.

Since the beginning of winter, in the face of the winter cold wave, snow and other weather characteristics and the characteristics of the equipment materials, the acrylic workshop has formulated targeted anti-freezing measures, and each team has done a good job of checking the heat tracing pipelines, unblocking the blocked pipelines in advance, and eliminating leaks in time to ensure Heat tracing is good. Strengthen the inspection of heat tracing pipelines, freezing points, and "dead corners of the cecum", and do a solid job of troubleshooting and eliminating defects in equipment to ensure the safe operation of equipment.

At the same time, the local workshops focused on strengthening the control of the self-control rate, establishing a self-control rate ledger, requiring employees to explain the reasons for manual control, measures and results in a timely manner, and technical personnel to follow up and solving them dynamically; strengthening the alarm management of operation points and requiring on-duty operators Fill in and explain the alarm reason of each control point in time to strengthen the smooth operation of the device.
