Contract distillation offer: Save resources now
What are solvents and where are they used?
Due to their special properties, solvents have become an essential part of industrial production: they dissolve and dilute gases, liquids and solids without chemically changing them. Solvents are an integral part of paints, coatings and adhesives and are mainly used in surface treatment, e.g. for cleaning, degreasing and rinsing processes. Furthermore, the pharmaceutical industry also uses solvents. Large paint and coatings manufacturers, as well as the automotive industry, are global consumers of solvents.
Why is it important to recycle solvents?
Most of the industrially used solvents are highly flammable mixtures, such as acetone, which are classified as hazardous materials. The disposal of contaminated solvents is often done by incinerators, which releases CO2 and pollutes our environment. The special thing about solvents, however, is that they can be recycled easily and efficiently, making them an ideal resource for the Circular Economy. With the distillation of solvents, up to 95% of the contaminated solvent can be recovered and fed back into the production process.
My company wants to produce in a sustainable way. What are the advantages of solvent recovery over switching to water-based products?
Over the past few years, to avoid the use and thus the disposal of solvents, a trend towards water-based cleaners and paints has emerged in the paint, coatings and printing inks industry. There is one main disadvantage in switching to water-based media: water is becoming increasingly scarce as a natural resource and is difficult to recover. Solvents, on the other hand, can be recovered to a very high degree through a gentle and efficient treatment process and can thus be used again and again in the cycle. By using recycled solvent, you therefore not only save CO2, but also conserve water as a natural resource.

With excellent distillate quality and a recycling rate of up to 97%, our technology clearly stands out from other suppliers.
What does SLD stand for?
The abbreviation SLD stands for Single Level Distillation.
What are the dimensions of the system SLD?
The SLD system measures 160 x 110 x 160 cm (w x d x h) and requires very little space for installation. With its weight of approx. 350 kg, it is practically a lightweight among the solvent distillation units.
Which connections are required for commissioning the distillation unit?
The SLD requires an electrical connection of 9.5 kW and a cooling capacity of 5.5 kW. WLAN access on site is also necessary to use the integrated software.
How high is the energy consumption of the distillation unit?
Due to our very gentle distillation process, the power consumption of the SLD distillation unit is only 0.3 kW per liter, which is many times lower than that of comparable systems on the market.
How high is the throughput of the distillation unit per day / month?
Our distillation unit SLD has a throughput of 30 tons per month, i.e. about 1000 liters per day. This value may vary depending on the solvent properties. If you need a higher throughput capacity, you can easily combine several distillation modules and add them as required.
The distillation units can be combined modularly. How does this help my company?
The modularity of our system creates redundancy, providing even more certainty for your reliable, uninterrupted production. Combining multiple modules minimizes the probability of failure and maximizes availability and process capability. Moreover, for periods when you have less throughput, for example, you can work more precisely by switching off one module.
Are the units tested and certified?
Yes, our distillation units are all certified according to ATEX and IECEX as well as TÜV tested.
Is the SLD unit subject to approval according to BImSchV?
According to the 4th BImSchV, distillation units are only subject to notification and approval if the volume exceeds 1000 liters per hour. Since our units are below this value, the obligation to notify and obtain a permit does not apply. Furthermore, distillation units are not included in the units listed in Annex I of the 31st BImSCHV, so that there is no notification and approval requirement in this case either.
In which hazardous area must the unit be installed?
The SLD unit is assigned to Ex Zone II.
Does the unit run fully automatically?
Yes, the SLD unit runs fully automatically and self-sufficiently. It takes the dirty material itself and discharges the recovered, clean distillate directly into the appropriate tank. The residue, i.e. the concentrated dirt, is fed out by the system itself into the tank provided for disposal. The SLD also independently recognizes whether a distillation process is worthwhile: it knows whether there is dirty product in the tank and whether there is sufficient space for both the clean distillate and the residue to proceed with distillation.
Which features do the integrated software and sensors of the unit have?
The SLD unit is the only distillation unit available on the market that is fully digitalized. A system of software, sensors and control modules ensures that the distillation process runs reliably. More than 20 installed sensors continuously record and analyze all relevant data, while the early warning systems provide for error prevention. You can freely configure all parameters, such as temperature, pressure, number of distillation cycles, but also CO2 savings and solvent recycling values, within the documentation function and call them up at any time via the monitoring dashboard and the app supplied.
Are maintenance and repair as well as spare parts of the units included in the service?
Yes, maintenance of the unit as well as repairs and spare parts are carried out by Ch.Batsch Verfahrenstechnik and are included in the price. In case of breakdowns of a unit, we will help you personally on site as soon as possible.
What are the spacial requirements for the installation of the units?
The minimalistic design of the unit allows an easy and quick installation at your site. If you do not have an Ex-Zone II area at your site, we can offer you a container model, which we are currently developing together with a partner. The container serves as a stand-alone Ex-Zone II and allows a safe and flexible installation of the unit.
What does a liter of clean recycled solvent cost at Ch.Batsch Verfahrenstechnik?
We set the price depending on your consumption and the effort involved. The effort depends on the respective solvent composition, which we determine in advance with a sample distillation.
How does Ch.Batsch guarantee the constant high quality of the recycled solvent?
Batsch Verfahrenstechnik guarantees the quality that has been determined during sample distillation. Remote control ensures high process stability and enables constant monitoring of the quality, so that deviations can be identified and corrected at an early stage.
What are the first steps of a cooperation with Ch.Batsch Verfahrenstechnik?
If you are interested in our technology and service for solvent recycling, please send us your non-binding request via the contact form. It is important for us to know which solvent (mixture) you have and how much of it. Based on your data sheets we analyze the components of the mixture and the feasibility of distillation. The next step on this basis is the sample distillation, for which we need 1000 liters of your dirty solvent. This test distillation provides information about the properties and reaction values of the solvent as well as about the composition of the residue. After sending you the clean distillate, we will work out a quotation together with you according to the results of the sample distillation.
