Baling Petrochemical: Gasification unit operates at high load at Class A level for 226 days, setting a new record Author/Source: Sinochem News Network Date: July 15, 2020 Clicks: 6 As of July 13, the gasification unit and related facilities in Baling Petrochemical’s coal chemical division have operated at high load at Class A level for 226 days, breaking the previous record of 225 days set in 2014 and 2017. Since the beginning of this year, the gasification unit at Baling Petrochemical has faced unprecedented challenges. With the spread of the COVID-19 pandemic during the Spring Festival, the unit has worked hard to implement strict epidemic prevention measures, while also overcoming difficulties related to a shortage of staff in order to organize production and ensure smooth operations. After the launch of the 100-day campaign to achieve efficiency improvements, the gasification unit issued another commitment for this 100-day period, aiming to ensure that the unit operates at a high load level of over 95% in order to guarantee its stable operation. In late March, the slag system of the gasification unit experienced severe fluctuations, leading to issues such as the detachment of the blades in the slag breaker and the inability of the equipment to operate properly – extreme conditions that arose as a result. To ensure the achievement of the goal of setting new records and striving to keep the gasification unit shut down only once throughout the year, all employees at Baling Petrochemical’s gasification unit worked together as one to proactively address any emergencies that might arise. On the one hand, promptly submit requests for spare parts procurement to prepare for shutdown maintenance ； On the other hand, a task force was established to work in shifts 24 hours a day, making frequent and meticulous adjustments to the manufacturing process. Over a period of more than 3 months, over 30 blockages in the slag discharge system were successfully resolved, and 4 sets of blades were removed from the slag collection tank, ensuring the unobstructed flow of slag. The expert team boldly proposed the idea of shutting down the slag breaker; after multiple rounds of technical research and validation, they developed a method for operating under the special condition of lowering the heat zone of the gasification furnace. Tong Jianxiang, director of the gasification unit at Baling Petrochemical, said, “We are the first facility in the domestic and international powder coal gasification industry to maintain long-term high-load operation even after shutting down the slag breaker.” ” Tong Jianxiang explained that the current global record for the longest continuous operation time of similar gasification units is 264 days. Based on its current operating conditions, the gasification unit at Baling Petrochemical is expected to achieve new breakthroughs. It is understood that in the first half of the year, despite the pandemic affecting nearly 10% of the average monthly load in February, the gasification unit at Baling Petrochemical achieved an average operating load of 93.6%. Since the launch of the 100-Day Effort to Improve Efficiency campaign, the average operating load has reached 95.8%, and merely increasing this load alone has resulted in an increase in production and efficiency worth 6.52 million yuan. At the same time, the equipment continued to operate, resulting in cost savings of 10 million yuan.
