A bench scale continuous Pump nitration unit, where our proprietary Pump nitration technology can be optimized, and various parameters and feed stocks can be studied in detail. The nitration of toluene to produce nitrotoluenes (MNT) and Di nitrotoluenes (DNT) has been extensively studied, as well as the process for nitration of benzene to dinitrobenzene (DNB) via nitrobenzene (MNB), and p-nitrotoluene (PNT) to 2,4- DNT.

Two bench-scale continuous stirred tank reactors (CSTR) hydrogenators are available, capable of operating at pressures up to 140 bar. One unit is smaller, while the other is larger in size. These hydrogenators can be operated continuously for extended periods, allowing the study of catalyst aging and other factors. The units feature the continuous addition of feed materials, which may be solids at room temperature (such as DNT, DNB, etc.). All data is continuously logged for later evaluation, and fresh catalyst can be added without interrupting the process.

Through careful parameter control, successful scale-up to commercial-sized hydrogenators (30-60 m3) has been achieved. The hydrogenation of DNT (isomer mixture) to toluene diamine (TDA), as well as 2,4-DNT to 2,4-toluenediamine (2,4-TDA), has been developed and optimized using our proprietary catalyst (CEAB Select®). The use of our proprietary catalyst offers superior performance in terms of selectivity and efficiency.

Furthermore, the hydrogenation of DNB to produce m-phenylenediamine (PhDA) is one of the latest processes that has been tested and developed. Our extensive hydrogenation expertise can also be utilized to develop other customer-specific products.

A state-of-the-art bench-scale continuous phosgenation unit is available for optimizing our isocyanates technologies (e.g., TDI and DCPI) and developing other phosgenation products. The unit is equipped with the most stringent safety systems and offers precise control over flow, temperature, and pressure. All data is logged for post-run evaluation. Additionally, the bench-scale unit can be utilized to develop custom products requiring phosgenation for external clients.

Chematur has the capability to design and supply phosgene production units to clients, ranging from small units for the pharmaceutical and fine chemicals industry to large-scale plants for bulk isocyanates production.

A sophisticated pilot plant for production of Hydrogen peroxide. The unit can operate 24/7 and be remotely supervised. Different working solutions and catalysts can be tested to evaluate the long-term behavior and prove and improve the performance of the process.

Equipment and know-how to test wastewater pre-treatment (WWPT) of various difficult waste-waters. The equipment includes a high temperature treatment unit, a moving bed biofilm reactor technology (MBBR). With the possibility of complimenting with a Fenton process.

A supercritical carbon dioxide (ScCO₂) extraction unit for general use in extraction of various feed materials with supercritical carbon dioxide. The pilot plant can operate up to 400 bar and 100 °C and it features a rotating disc in the extraction chamber or fixed bed extractors, making it an ideal unit to test the debinding of powder injection molded components in a gentle and high performing process or extraction of fatty component from a substate material.

A bench-scale unit is available for the production of ethylene from ethanol. This unit is used to optimize operating parameters, evaluate different raw materials, and conduct long-term evaluations of catalysts.

All bench-scale and pilot units are connected to a DCS of the same type that would be installed in a commercial-sized plant. This ensures seamless data monitoring and control throughout the testing and evaluation processes.

Furthermore, we possess the ability to perform fermentation tests on various raw materials for our Biostil™ Ethanol process.
