In summer, high temperatures and frequent thunderstorms may adversely affect the safe and stable operation of the plant. The Yangzi Petrochemical olefin plant was laid out in advance, prepared as early as possible, and measures were put in place to ensure the safety and stability of the equipment during the past summer. All kinds of insecurity were imposed. The unstable factors are eliminated early in the bud, and the 'protective net' is set up for the device's summer.
Yangzi Petrochemical Olefins Plant cuts out and overhauls key summer equipments such as circulating water pump, cool water tower fan, water heat exchanger, ice machine and other devices in advance. Hot weather in summer may affect the production and backup of production. Pump oil system, cooling water system to carry out a comprehensive and careful inspection, make a spare engine pump regularly, ensure that the pump is in good operation, intact spare. At the same time, the olefin plant do a good job in the equipment control room and production of air-conditioning equipment before use Inspection and maintenance, rain protection is carried out on the roofs of the central control room and substation, between the instrument cabinets, and the leakproof special inspections are eliminated. Collaboration with the electric instrument personnel on the spot electrical equipment, instrumentation and equipment sealing waterproof performance inspection eliminates, implements protection against rain, moisture Measure, make lightning protection and grounding, detect and repair electrostatic grounding facilities, inspect, clean and dredge the on-site cleaning and diversion system, ensure unobstructed drainage, implement equipment and plant ventilation cooling measures, do a good job of circulating water, check fire water system Switching. The workshops of the olefin plant are equipped with features and difficulties for over-summer. Based on the summarization of past experience, combined with the actual situation, new “special care” measures are taken to strengthen the Quarter production and operation management and control.
The ethylene unit increased the daily inspections in the cracking furnace area, focusing on the inspection and maintenance work of the cracking furnace waste heat boiler, drum level gauge, cracking gas large valve and other key parts, checking the cracker fan vibration, lubrication, bearing temperature Whether it is normal and at the same time, strengthen the 'special care' management of the 'six major' units, closely follow the 'six major' oil circuit systems, rehydration systems, dry gas sealing systems, steam system operating conditions, record daily, analyze process operating parameters , Optimize operations, Strengthen management, Responsibility to posts, To people, Put 'special care' measures in place, Find problems and solve them in time, Ensure that the 'six major' units are safe and stable in summer. The ethylene glycol workshop focuses on the air cooler fins Tubes, plate heat exchangers, condenser head tubes, ice oil coolers, and all-in-one pump seal coolers, bearing box jackets, cooling water lines, inspection, cleaning, dredging, complete removal of residual dirt, improved Summer heat exchange, cooling, cooling effect. The butadiene plant will implement two sets of butadiene plant summer plan measures to the workshop professional management staff and each team, each Every operator, everyone cooperates with each other and supervises each other. The workshop does a good job in eliminating the need for spray system inspection of butadiene finished product tanks, ensuring that spray equipment facilities are in good condition and ready to use, and satisfying summer high-temperature butadiene product spherical tanks. The need for cooling down. In addition to doing a good job in the switching of water pumps for each set of circulating water devices in the public works workshop, the cooling tower fans of the circulating water devices are inspected and eliminated, but also the breathing tanks, breathing valves and spray devices of the various tanks in the raw material tank area are strengthened. Inspect, eliminate hidden dangers, achieve good standby, well use, spray equipment can start immediately when needed, implement spray cooling, ensure safe production of raw materials in summer.
