The main components of drilling waste mud include environmentally harmful oil, water, various types of polymers, synthetic organics, debris and other substances. The drilling waste mud contains a variety of toxic pollution factors, which are damaging the environmental, animals and human beings heavily. In order to solve the drilling waste management, Beston has developed the drilling mud recycling system.
The drilling waste mud pyrolysis plant for sale takes advantage of pyrolysis technology, which can turn the drilling waste mud into about 72.5% solids, 12.5% fuel oil and 15% water by high temperature heating.
Process of Beston Drilling Mud Recycling System:
1. Feed Raw Materials
Put drilling waste mud into reactor by manual or auto-feeder. Seal the feeding inlet door tightly and make sure there is no gas leakage.
2. Pyrolysis of Drilling Waste Mud
Heat the reactor by using coal, charcoal, fuel gas, wood etc. as heating materials. The oil gas will be gradually generated when the temperature reached 250℃.
The lighter oil gas coming out from the reactor then go to condensing system and get liquid oil.
4. Waste gas recovery
The gas which can’t be liquefied under normal pressure will be designed to go back to combustion system through safety device. It can be recycled to heat the reactor as fuel, which will save energy for the whole pyrolysis process.
Through high temperature heating, the solids and water are separated from the oil gas, and they can be directly discharged when the reactor’s temperature falls down to 40℃.
Multiple selections of the drilling waste mud recycling system:
In order to satisfy various customers’ requirements, we have manufactured our drilling waste mud recycling systems into six models, BLJ-06, BLJ-10, BLL-16, BLL-30, BLL-40 and BLL-50. It needs to be mentioned that BLJ-06 and BLJ-10 are batch operating systems; BLL-16 is semi-continuous system; BLL-30, BLL-40 and BLL-50 are fully continuous systems. The three systems have these differences:
1. The semi-continuous system and fully continuous system have an auto-feeder which can feed the materials into reactor automatically, while the batching pyrolysis plant need to feed materials by manual.
2. The reactor of our auto operating pyrolysis system is stable and not rotary, which makes the temperature rise and pyrolysis react quickly. This special design makes the whole pyrolysis process efficient and can also save much heating materials. While the reactors of batch and semi-continuous systems are 360-degree rotating. This special design makes the bottom of reactor heat evenly, which lengthen the service life of reactor as well as improve the pyrolysis speed.
3. The fully continuous drilling mud recycling system can work continuously for 24 hours per day without a stop and needn’t to be cooled before the second batch. The semi-continuous system can work 3-4 shifts per day, and it only need one hour to cool the reactor before the second batch. The batch plant can only work one shift per day, and need to 5-6 hours to cool the reactor.
