Reactors

A chemical reactor functions as an enclosed vessel where chemical reactions occur. It's crucial for process designers to ensure the reaction proceeds efficiently toward the desired product, maximizing yield while minimizing costs associated with procurement and operation. Operational expenses encompass factors like energy input and disposal, raw material costs, labor, and other associated charges. Typically, reactants and products within the reactor are in fluid form, either gases or liquids. Continuous reactors maintain a constant operational state, while batch reactors undergo transient operation. Transient operation occurs when a reactor is activated for the first time or following a shutdown, with critical process variables fluctuating over time.

Lödige DRUVATHERM® reactors are batch reactors. Rotating mixing elements adapted to the specific process, installed in a cylindrical drum equipped with a temperature control jacket, create a three-dimensional product movement. The resulting contact frequency of the reacting agents with each other leads to a more effective conversion with a higher yield. The high-speed mixing elements ensure high contact frequency of the reacting agents with each other and intense contact of the reacting agents with the heated or cooled vessel wall. This makes reactions in homogeneous and heterogeneous phases possible in practically all combinations (solid/liquid/gaseous). The production consistency can be anywhere along the spectrum of liquid to pasty to lumpy to pourable. High-speed rotating choppers installed on the side of the machine drum perform additional mixing work to distribute the reacting agents.

Pressure vessels/containers and reactors must meet the highest quality requirements. The pressurized objects are designed at KASAG according to the relevant regulations and subsequently produced, with great enthusiasm, using the most modern technology. Stainless steel and special materials, such as duplex and nickel-based alloys (Hastelloy, Inconel) are processed. All our production experts have the mandatory certificates, and have mastered the welding process MIG, MAG, TIG, Plasma and Orbital and work solely with certified welding consumables. The pressure vessles and chemical reactors are finally polished, pickled, passivated and tested using non-destructive test methods. KASAG products meet all your standards.

The Large Volume Processor program consists of horizontally arranged, heated reactors with twin (co- or counterrotating) shaft which provide intensive mixing and kneading. The highly versatile large volume processors Reasil and Reacom are characterised by the following advantages: Very large volumes The highest viscosity melts (up to 15,000 Pas) and solids can be processed efficiently Low shear processing Long residence times are achieved economically Mixing, devolatilization, reaction and phase change (from melt to solid) can take place in the same machine. A successful devolatilization or reaction system consists of the right processor design integrated with properly engineered subsystems. SMS can provide a complete system, including installation and start-up services, or full engineering and design documentation to allow you to add the necessary subsystems for our high volume processors.
