R & D Background
Domestically, the most common coke handling systems that are currently used are open-pit, resulting in uncontrollable air pollution by dust, stench and smoke. The pollution created from coke production has been a common problem traditionally plaguing the petrochemical industry. The adverse impact on the environment is an issue that urgently needs to be resolved by refineries located in proximity of the residential area across the country.
Another process, more commonly used in other countries, is the “coker tower/crusher/mud lift pump/dehydration bin/settling tank”. Such processes cause pump to lift, require large amount of water for circulation, and require large work area. Most of the equipment in older plants is constrained by limited work area.
Due to the staggered timing on the hydraulic decoking equipment, the retrieval of materials, and buffer coke pit, the impact of equipment failure on decoking is minimum.
Due to the fact that the crusher and the auger used in the system’s main equipment have been around for a long time, this results in high reliability and ease of maintenance for the system.
Air pollutants are collected in the closed system, it effectively reduces the VOCs emission and dust pollution.
The system requires small work area, it is more suitable to the equipment in older plants, and it requires minimal retrofitting to the original device.
The original grab crane can be maintained and it increases the system’s reliability.
