ANALYTICAL INSTRUMENTATION


Distillation specialists give helping hand to developing the green fuels of the future emissions is an important current objective in reducing global warming. The scale and scope of


Reducing CO2 this reduction of CO2 emissions needs to be significant and should be achieved as quickly as possible.


Even with exploring more and more sources of fossil fuels, together with the allied technical improvements in extracting more products out of already existing wells, it is clear that the availability of mineral fuels will end one day and will require replacement by green fuels in order to keep the wheels of industry and commerce turning.


Governments around the globe have decided to lead their countries to a climate-neutral state in the future, in other words, the goal is “zero emissions”. In this regard, the use of well-established technologies with clean energy offer immediate answers. The combustion engine is a well-known technology and liquid-fuel is one of the energy sources with a significant energy density, easy to transport and store and with an already existing corresponding distribution.


The only challenge remaining is: what could be a plausible alternative “green fuel”?


The solutions are almost ready to be implemented: ILUDEST has participated in several projects at universities and research institutes in the field of these renewable energies. One of these alternative fuels is OME (Oxymethylenether) which burns with almost no carbon particles. The OME is produced in a reactor. During the reaction process several by-products, along with OME, are produced. To reach the quality of a Diesel substitute, the OME must be purified in a distillation unit with a high separation efficiency.


It does not take much to turn dreams into reality: tomorrow’s value chain is supposed to be climate-neutral, or at any rate sustainable, and preferably without the use of fossil raw materials. However, the technology that promises prosperity for all without environmental pollution is still a long way off. Today, no one disputes that it is possible in principle to produce fuels and basic chemicals from renewable energy and waste gases. However, these processes also must be economic. And so, institutes, companies and politicians seek the mythical ‘philosopher’s stone’ of instant success in chemical synthesis.


“The processes we need are actually already developed,” says someone who should know: Jakob Burger,


Professor of Chemical and Thermal Process Engineering at the Technical University of Munich (TUM), is researching the direct synthesis of artificial fuels with his team at the TUM campus in Straubing, in Germany. The means equipment required is a reactor about the size of a table, plus distillation columns several metres high and a downstream membrane unit. This is a typical pilot plant set-up—but very robust and one that packs a significant punch!


ILUDEST designed and manufactured the distillation modules, comprising two towers, one in glass for operation under vacuum, and a second in stainless steel for operation under overpressure.


Alternative fuels contain several short-chained molecules with very low boiling points. These short-chained molecules must be separated, but separation of these products normally requires very low operating temperatures. Low temperatures can be reached by using expensive cryostats, but another way is to increase the operational pressure of the system. This leads to higher throughputs at the same column diameter compared to atmospheric pressure. The critical point of the products, the possibility to fill and drain the system, as well as pressure equipment directive and explosion proof design must be considered. Pressure distillation units can be realized in stainless steel or special materials, like Hastelloy.


Separation of alternative fuels has also been investigated in a multiple dividing wall column. Inside the column the ascending vapour stream can be separated into two separate parallel working columns. The backflow of one column can be separated as well into two columns.


All customer’s enquiries do contain the challenge of combining high separation efficiency with low temperatures, respective pressurized equipment, including the challenge to fill and drain the system adequately.


Publications about further projects already effected are under preparation and will be brought to your attention once available.

The latest generation of S-flow builds on the strong foundation of its predecessors to offer the ultimate in automatic viscosity testing of Newtonian samples such as petroleum products, complying fully with ASTM D7279 and correlating with ASTM D445. The system offers all the tried and tested advantages of a Houillon-type tube design such as short process times, small sample volume, and low solvent consumption.


The new S-flow IV consists of a 2-bath system with 2 tubes in each bath, providing a total of 4 tubes. The baths were designed to work independently, making it possible to use both +


baths at the same temperature, or at different temperatures, ranging from 20 °C to 120 °C. Other options include dual solvent cleaning and integrated Duplo testing which obtains 2 flow time determinations with only 1 sample injection.


When paired with the Cito autosampler the S-flow turns into a fully automatic system. The Cito can work together with 1 or even 2 S-flow systems at the same time. The Cito S-flow IV autosampler has excellent repeatability and the multiple tray options make the Cito a very flexible system, while still easy to operate. The Cito autosampler is a highly efficient, compact, fast, and affordable system, operates unattended and it increases both productivity and efficiency in your lab, making it the ideal autosampler for kinematic viscosity applications.

Houillon viscosity automated


Cito S-fl ow IV Autosampler


FOR HIGH THROUGHPUT AND UNATTENDED OPERATION


The first dedicated automatic sampler for Houillon kinematic viscosity testing. Cito S-flow IV autosampler works autonomously, provides excellent repeatability, and offers high throughput. It is customizable for different sample trays, can be added to any existing S-flow IV+ system in-field, and can service up to 2 S-flow IV+ instruments (8 tubes).

EXCELLENT REPEATABILITY


The Omnitek U-Visc combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/D446, the specially designed viscometer tubes cover a 100-fold range.


The capillary tubes are based on the well-known and proven Ubbelohde design. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in lubricants between 0.15 and 25,000 mm2


Designed to be versatile and flexible, yet easy to use. Different models are available ranging from 1 bath with 1 or 2 tubes, up to 2 baths with 1 or 2 tubes per bath, where each bath works independently. Each bath features a sampling tray with 16 samples per tube, allowing completely unattended operation at different temperatures. Depending on the viscosity of the sample, the instrument can process up to 10 samples per tube per hour, leading to a maximum capacity of up to 40 samples per hour, satisfying even the needs of high volume labs running several hundred samples per day. An optional sample preheater allows processing samples such as waxes and heavy fuel oils as well.

HIGH THROUGHPUT


Omnitek introduces a fully automatic viscometer for highly viscous samples up to 120,000 mm2


types that pose great challenges to automatic sampling, measurement and cleaning because of their high pour point and viscosity.


SERVICES UP TO 2 SYSTEMS


The instrument was especially developed for demanding applications of high temperature and high viscosity products such as vacuum residue, additives, crude oils, waxes, heavy fuel oils, polymers, asphalts, etc. Because of the problems associated with heating, sampling, measuring, and cleaning these types of samples, users were forced to resort to manual processing, which is a long and tedious process. Featuring a sample preheater and covering a range up to 150°C and 120,000 mm2

HIGHLY ACCURATE


of automatically measuring these types of samples, resulting in very substantial time savings. By implementing specially designed Duplo measurement tubes based on the proven Ubbelohde viscometer type, the precision of the obtained results far exceeds requirements in ASTM D445 and D2170. An innovative cleaning system ensures that even the toughest samples are cleaned effectively from the inside and outside of the tube, preventing any cross-contamination.
