AB Sandvik, a leading engineering group, there is a slight problem. In the production of non-standard stainless steel tubing and piping they use a paraffin oil which is both very high performance and chlorinated. With a total volume of around 100m³ this oil serves eleven pilger mills.
With a total volume of around 100m³ this oil serves eleven pilger mills.
The oil is, by it’s very nature, rather hazardous to the environment as a whole and contains extremely large quantities of submicron particles. As time goes on, this oil will eventually contain twenty to forty percent of its total volume as these particles.
Productivity decreases of twenty to thirty percent are to be expected over the lifetime of this oil, which must then be disposed of appropriately. Naturally, the destruction of this hazardous material brings a high cost and then new oil must be purchased.
In order to both reduce the high pricing required by both the oil and it’s disposal, Sandvik developed a desire to find a way to recycle the material.
Recondoil’s ROCCO filtration systems are made to be used both “in-line”, meaning within the normal circulation of oil, and “off-line” meaning as an on-site unit which is configured to regenerate the oil which is being used in an industrial process.
The ROCCO VF unit consists of processing tanks, vacuum filtration, and storage tanks in which the Dual Seperation Technology(or DST) take can take place on-site.
These units are configurable for nearly any type of oil imaginable, and are thus adaptable to a wide variety of different manufacturing and processing processes. With Recondoil handling the logistics, it was soon apparent that the results for Sandvik’s pilger mills were astounding.
Environmentally Sound Circular Economy
By utilizing Recondoil’s facilities, Sandvik was able to not only improve their efficiency but also help the environment. The statistic breakdown of the whole process ends up being nearly unbelievable.
The recovery rate of the specialized oil ranged from 95%-99%.
This entire process takes only twenty four hours for the per cubic meter of oil. The waste results in a dry cake-like matter which can then be disposed of in a safe manner without incurring extreme costs for handling and disposal.
This also allows the company to avoid having to spend money on other filtration systems, saving even more expense while allowing the process to be almost entirely green.
And the same technology can be utilized for other pilger oils.
Recondoil-Green and Efficient
The results really speak for themselves in this case. The hazardous oil which previously plagued the systems of the Sandvik’s pilger mills and the environment itself can be regenerated. This means removing the need for the production of more of the specialized oil, as well as making the waste product an easily handled cake-like slag which reduces the hazardous materials which make their way into the environment.
Recondoil’s dream of a circular economy of oil, in which they take on the logistics of handling these products and removing reliance on the continuous production of oil can certainly be accomplished and their case of handling Sandvik’s eleven pilger mills is yet another example.Best of all, for Sandvik, the costs associated with their oil has been reduced and their efficiency increased by being able to rely on and support Recondoil’s mission to create an almost entirely closed loop of oil. A mission which they prove, time and time again, to be well worth doing.
