cn Chongqing Petroleum Tonghui Company’s Fuling LNG plant is the first LNG plant designed with Sinopec’s independent intellectual property rights.
At noon on August 27, the plant’s production capacity reached 1 million cubic meters per day, which is the next step for the plant.
High-efficiency creation and dedication of clean energy provide greater protection, marking the more mature application of Sinopec's liquefied natural gas technology
.
Since the refrigerant compressor in Fuling LNG plant was in operation, the shaft vibration has been abnormally increased at high speeds, and the compressor speed has never reached the design speed
.
Tonghui cooperated with equipment manufacturers to carry out unit online problem detection, analyze the cause of unit failure, and overhaul the equipment as a whole during the overhaul this year, especially the high-speed dynamic balance overhaul of the compressor rotor.
The refrigerant ratio of the liquefaction system is a key parameter of the cooling capacity, which is directly related to the processing capacity of natural gas.
Tonghui contacted the original design unit for careful calculation, combined with the actual operating conditions on site, and worked out the optimal refrigerant ratio.
And strictly monitor the refrigerant ratio in actual production, and provide more cold capacity for natural gas liquefaction under the same refrigerant circulation volume
.
Under the condition that the refrigerant compressor has a certain processing capacity, it is the key to take full advantage of the refrigerant.
Since 2020, Tonghui has reduced the temperature of the refrigerant entering the compressor by adjusting the outlet temperature of the circulating water of the main heat exchanger of the liquefaction system.
A substantial reduction in energy consumption has been achieved, natural gas processing capacity has been improved, and the operating parameters of the heat exchanger can be optimized to extend the service life of the equipment
.
In the next step, Tonghui Company will continue to practice energy-saving and environmentally-friendly production management concepts, explore more practical experience in the operation of LNG plants, ensure the stable and long-term operation of the installations, contribute more clean energy to the society, and build a world leader Clean energy chemical companies make greater contributions
