THE OPTIMIX® REACTOR
-
Exclusively from De Dietrich Process Systems, the OptiMix® reactor offers tremendous optimization of the mixing performance of glass-lined steel reactors by integrating three baffles on the vessel wall.
OptiMix® reactor: The efficient technology
This patented design enhances heat transfer, solids suspension and distribution, gas dispersion, gas flow rates and mass transfer.
The OptiMix glass-lined reactor's performances are based on the integration of three baffles onto the vessel wall. This leads to a notable improvement in the capacity of the mixture and in heat transfer compared to the standard DIN series.
The result is that all the nozzles remain free for the process. This arrangement considerably improves the hydrodynamics by using an optimized baffling effect.
The profile of the paddles prevents the accumulation of crystals in the event of crystallization. This design satisfies two of industry's primary requirements: optimal process efficiency and improved cleanability of the reactor, as well as a reduction of the amount of dead zones which generally occurs with a standard, nozzle-mounted baffle.

THE GLASLOCK® SYSTEM
-
The GlasLock system allows installation of specific blade profiles as well as several flights of blades to better suit the process requirements. This system, therefore, makes it possible to obtain small, non-agitated volumes less than 1%.
The only system in the world with removable blades
This system has been especially designed for BE reactors where the main opening is the manhole, but is usable for all kinds of reactors.
Fitting and dismantling are carried out laterally, making it possible to work on the scraping agitators without completely dismantling them. With multi-tiered agitators, it is possible to modify just one stage independently of the others by leaving the agitator in place.
The assembly of a blade in its conical emplacement, both fully enamelled, is done using a manual tool according to a simple procedure. GlasLock uses a single hub offering greater flexibility by allowing all types of blade profiles to be fitted. This technology reduces the time needed to dismantle the drive, when this is required.
Our teams can define and install a blade profile according to your process and your agitation parameters. This technology makes it possible to fit several flights of blades to better suit the reaction.

STRUCTURED PACKING DURAPACK®
-
- made of borosilicate glass 3.3
- highly corrosion resistant
- high separation efficiency-
- low pressure dropThe efficient solution for highly corrosive thermal separation processes
CONCEPTThermal separation processes are often used in treating and cleaning chemicals. Very common are processes that involve two liquids or a liquid and a gas. The processes used mainly involve extraction, absorption, desorption or stripping, distillation or rectification. These separation processes require mass transfer between two phases; in the above rectification example, the mass transfer between the liquid and gas phase. Keeping the equipment used in this process as compact as possible requires creating as much mass transfer surface in as small a volume as possible. DURAPACK® ensures high flow rates with low pressure drop and at the same time huge mass transfer areas for an efficient separation.
In order to intensify the mass transfer in absorption, desorption, distillation and extraction columns structured packing DURAPACK® from borosilicate glass 3.3 is the best choice for corrosive media. Applications are among other are therefore corrosive chemicals such as sulfuric acid, nitric acid, other mineral acids such as HCl but also halides such as chlorine, bromine and iodine: short wherever metal material but also plastic fail.
DURAPACK® patented structured packing consists of alternately allocated corrugated plates made of borosilicate glass 3.3 with channels at an angle of 45°. In order to increase the turbulence the corrugations are notched. The packing is only made from borosilicate glass 3.3, i.e. the plates are sintered together without any gluing material so that only borosilicate glass 3.3 is in contact with the media to be processed.
The easy-to-clean smooth and inert surface is extremely convenient.
EXTRACTION
-
The dissolving process of a chemical component with a liquid out of a second non-gaseous phase is called extraction. The dissolving process of a chemical component with a liquid out of a second non-gaseous phase is called extraction. Depending on the kind of the second phase this process is named either solid/liquid extraction or liquid/liquid extraction.
Liquid/Liquid Extraction Solutions:
- Batch operated Mixing/Settling Units
- Continuously operated Mixer-Settlers
- Continuously operated Extraction columns
Solid/Liquid Extraction Solutions:
- Soxhlet Extraction Units
- Trickle Bed Extraction Unit
- Over Flow Extraction Units
SOLID/LIQUID EXTRACTION
-
Solid/Liquid extraction process is a very common process in the pharmaceutical, cosmetic and food industry to obtain natural ingredients as e.g. flavors and fragrances from natural raw material.
The extraction can be carried out with cold or hot solvents.
The solid raw material is packed in a container with a retainer on the bottom called extractor B2 and extracted batch wise.
The solvent is guided through the extractor in different ways
- Continuous trickle bed extraction
- Continuous overflow extraction
- Soxhlet extraction (periodically filled and drained container)
Using solvents with a lower density than the raw material avoids floating of the raw material and eases the process.
Very often the solvent is evaporated in B1 from the extract directly after leaving the extractor, then condensed in W2 and guided back into the extractor B2.
LIQUID/LIQUID EXTRACTION - Batch mode - Mixers/Reactors
-
Whereas distillation takes advantage of different volatilities means different distributions of a product in the liquid and the gas phase the liquid/liquid extraction is based on different solubilities means different distributions of a product in 2 co-existing liquid phases.
For the extraction of a product (white dots) out of the so called feed liquor (blue liquid with white dots) a suitable solvent (yellow liquid) has therefore to be found. The first step of an extraction process is mixing for an intensive contact of both liquid phases to enable the mass transfer of the product (white dots) from the (blue) feed liquor into the (yellow) solvent. The second step is the phase separation or settling of the 2 liquid phases. After the extraction of the product the feed liquor is called raffinate (blue liquid with less white dots) whereas the solvent containing the product is called extract (yellow liquid with white dots). For the recovery of the product the solvent has to be separated in a subsequent third step from the product which is mostly done by distillation
Batch mode - Mixers/Reactors.
Using a mixer in batch mode offers a huge flexibility to optimize the mass transfer by varying ratio of the liquid phases, the type of stirrer, stirrer speed and mixing time. The settling period can also be easily influenced by varying the time. Such a batch operation is labor sensitive and requires sufficiently big equipment.
What can be done in the laboratory scale with a separation funnel can be realized in a bigger scale with larger quantities in a more defined way by using tempered mixers having basically the same functionality as batch reactors for reactions in the liquid phase. This is especially advantageous for the extraction of reaction mixture as it can be carried out in the same equipment as the reaction. Mixing can be adjusted by the stirrer shape, speed and mixing time. The phase separation is a question of time and can be observed advantageously in glass reactors. For the phase separation it is necessary to determine the location of the interphase. In the reactor this can be measured by systems based on a floater, a radar signal or the conductivity depending on the system to be examined. Outside the reactor it is also possible to detect the interphase while draining the lower means heavier phase through the bottom outlet by visual inspection through a glass pipe or by the sudden change of media property.

Heat exchangers made of inert, non-metallic materials are a requirement in the chemical and pharmaceutical industries where it is essential to avoid any interaction between the materials of construction and the substances being processed. In addition to chemical resistance there is a prime requirement for resistance against abrasion and easy of cleaning of the equipment.
It is usually not possible to fuse-join or weld non-metallic materials which meet these requirements, so that the tightness of the heat exchanger depends on the quality of the sealing between the inner tubes and the tube plate.
Considering the different thermal expansion coefficients and the possible temperature differences in the equipment these seals must be capable of taking up any linear expansion that occurs.

CONDUCTIGLASS
-
ConductiGlass® enamel prevents any risk of electrostatic damage on glass-lined equipment
The solution against electrostatic damage
In a glass-lined reactor, electrical insulating properties of the lining prohibit charges to flow to the ground and enhance their accumulation to very high voltages that become dangerous for the glass lining. This problem which was one of the last remaining in glass lining technology is solved by the use of the glass lining called ConductiGlass.
The principle of the ConductiGlass solution consists in increasing the conductivity of the glass lining to a value high enough to allow the discharge to the ground the electrostatic charges created, prohibiting then their accumulation at the glass surface up to dangerous voltages.
This is achieved by adding a small quantity of very thin Platinum fibres, homogeneously dispersed in the whole thickness of the glass lining, which remains made of DD3009 standard glass.
These fibres are not joined, but the glass thicknesses which are in between them are extremely small and can be compared to a network of micro-condensers discharging in line to let the electrostatic charges flow gently to the ground without any damage to the glass lining.
The first ConductiGlass equipment have been installed in 1998, and more than 100 reactors are working actually, replacing vessels previously damaged by electrostatic discharges, in activities as different as production of medicines, pesticides, resins, electronic components, using solvents like toluene, chloroform, ether, n-heptane, benzene, …
ConductiGlass advantages- Delete any risk of electrostatic damages
- Easy to implement on any kind of glass-lined equipment
- Continuous intrinsic property of the whole thickness of the glass-lining during all the life-time of the equipment
- Dielectric controls and Email Test monitoring remain possible
