Jilin Petrochemical catalyst mechanical loading efficiency
For the first time, the Jilin Petrochemical Ethylene Glycol Plant has implemented an advanced domestic technology based on the Beijing principle, developed independently by Equipment Maintenance Co., Ltd. This innovation is used to refine and dispense imported barrel-packed catalysts, significantly reducing labor demand and boosting operational efficiency.
The ethylene glycol plant uses catalysts that are stored in large barrels. Before loading them into the reactor, each individual tube must be filled with precisely measured small bags of catalyst. This process involves dividing over 50 tons of catalyst into more than 9,570 portions, a task that was previously done manually—slow, labor-intensive, and prone to errors.
To address this challenge, the plant introduced a specialized sub-equipment system. This advanced tool ensures even distribution, maintains accurate dosing, and reduces the need for manual weighing. As a result, the time required to reload the reactor has been cut from one week to just two and a half days, greatly improving productivity and minimizing human error. The new system not only streamlines the process but also enhances safety and consistency in catalyst handling.
