【Petroleum Chemical Antifreeze Measures in Action】Qilu Petrochemical ensures that all antifreeze and anti-condensation measures for equipment are properly implemented
Thread Content
Qilu Petrochemical is taking proper measures to prevent freezing and condensation this year, ensuring that all necessary actions are carried out to protect equipment from such issues. As reported on November 16th, a winter rain fell suddenly, causing temperatures to drop sharply. Early in the morning, Zhang Yuxin, an employee from the cracking unit at the olefin plant, carried his tool kit and used an umbrella as he went to inspect the hydrogenation area of the ethylene plant. Although it was cold, he carried out a very thorough inspection of the operating equipment. Shan Lianchun is a team leader in the cracking workshop of the olefin plant. Like Zhang Yuxin, their main focus these days has been to check the heating systems of the plant’s equipment. They are responsible for preventing freezing and condensation in this area during this winter, and as frontline team members, they have to inspect the area regularly due to its large size and the numerous, complex heating systems involved. They do this in order to ensure the safe operation of the plant during winter. Since late October, in order to carry out effective anti-freezing and anti-condensation measures this year, the cracking unit of the olefins plant has conducted early inspections of the areas that have tended to present problems in previous years. They checked the insulation, heat tracing, traps, drain systems, and condensate removal mechanisms of the equipment to ensure that all necessary anti-freezing and anti-condensation measures for the equipment, pipelines, and pumps were properly implemented. While taking proper measures to prevent freezing and condensation, they also focus on reducing energy consumption in the installations; they use heating equipment appropriately depending on temperature changes, and strictly prevent unauthorized discharge of waste, thereby saving energy to the greatest extent possible.
“The fourth quarter is a critical phase for achieving the annual goals. All 6 production units in the plant must work tirelessly to ensure ‘no accidents’ occur. While manufacturing new products such as high-temperature resistant pipes that are in high demand in the market, greater attention must also be paid to safety in production. Preparations should be made in advance to deal with freezing conditions as winter approaches, so as to ensure stable production. ”On October 14, the Plastic Plant of Qilu Petrochemical put forward strict requirements at the meeting. At present, the factory is actively implementing the “five in place” measures to ensure proper prevention of freezing and condensation. Responsibilities are properly assigned. The factory established a leading group for anti-freezing and anti-condensation work to ensure proper coordination and the arrangement of tasks, with a focus on formulating winter safety production plans as well as anti-freezing and insulation protocols. At the same time, clarify the division of responsibilities and implement a three-level management system at the factory, workshop, and team levels. Each piece of equipment, each process pipeline, and each valve must be registered, with a responsible person assigned to each one, ensuring that everything from entire units to individual valves is maintained by dedicated personnel. Proper training and education are provided. Recently, the various workshops at this factory have taken advantage of regular safety meetings, workshop coordination sessions, team safety meetings, as well as pre-shift and post-shift meetings to organize employees to study topics such as the \"Winter Safety Production Plan\" and the \"Key Points for Preventing Freezing and Condensation in Equipment.\" Educational activities are carried out through specialized lectures, picture exhibitions, and case analyses. In addition, employees receive targeted training on winter equipment maintenance, safe production practices on site, and the proper use of personal protective equipment, all aimed at ensuring that measures to prevent freezing and condensation are effectively implemented. Check that the rectifications have been properly carried out. The factory has requested the relevant factory-level management departments and staff to further change their working style, go straight to the task at hand, and visit the 13 grassroots workshops in order to inspect one by one those areas prone to low-temperature failures such as key heat tracing systems and condensate drainage points. Plans for addressing the potential hazards that could affect safe production during winter have been formulated, and these plans have been assigned to the relevant departments and responsible persons, thereby laying a solid foundation for safe production in winter. All supplies are in place. The various grassroots workshops in this factory prepared in advance the materials needed for preventing freezing and condensation. In particular, additional protective measures were put in place for key machinery, special equipment, and critical production positions. The management of freezing and condensation prevention was strengthened for idle equipment and pipelines, as well as for newly added protection points, so that potential hazards could be addressed early on, thereby strengthening the foundation of safety management. The contingency plan drills were carried out properly. Recently, base workshops such as those for high-pressure polyethylene and high-density polyethylene have carried out emergency drills for preventing freezing and condensation, taking into account the characteristics of winter production and past winter incidents. These drills aim to ensure that personnel are proficient in the skills related to preventing freezing and condensation and understand the corresponding measures, so as to effectively implement these preventive actions and enable the plants to operate stably, continuously, and optimally during winter.
