榆炼绿色停工有序推进

Core Viewpoint - Yulin Refinery has successfully implemented green and safe shutdown measures during its maintenance period, ensuring environmental compliance and operational efficiency [1][2]. Group 1: Maintenance and Environmental Measures - Yulin Refinery has entered the maintenance phase for its 2.2 million tons/year atmospheric and 600,000 tons/year catalytic units, with other units also in the shutdown and purging stages [1]. - The refinery has adopted a "closed purging, green shutdown" approach, emphasizing strict environmental control principles to prevent emissions [1]. - Specific measures have been established to manage potential emissions of gas, oil, and agents, ensuring zero pollution during the maintenance process [1]. Group 2: Operational Efficiency - The refinery has optimized material balance and prepared sufficient material reserves prior to the shutdown [1]. - To address the high demand for utilities and the significant consumption of steam and nitrogen during purging, Yulin Refinery has implemented a "staggered wind" purging strategy [1]. - Each group has designated a leader responsible for monitoring pressure, flow, and temperature to prevent equipment issues during the purging process [2].
