Air Dehumidification in the Chemical Industry

Whether it is a matter of binding raw materials together permanently, pulverising liquids or preventing potential side effects of reactions in applications such as tablet pressing: The quality demands on raw materials and end products are particularly high in the chemical industry. It is especially important that the environmental parameters can be monitored and controlled so that they can support the relevant processes optimally. The importance of high-precision air dehumidification in this context is demonstrated in a variety of applications. Lightly water-binding materials, in particular, require optimum air humidity to ensure smooth further or final processing, but above all to produce chemical products that meet reliable efficacy and quality standards.

Raw Materials React with Air Humidity

To ensure optimal industrial processing and the damage-free storage of chemical substances, dehumidification systems need to be designed so that they are precisely adapted to manufacturing companies’ needs. Such system solutions usually start with the delivery of the raw and source materials so that the advantages of optimum humidity control can already be offered during this phase. Important here: Even slight deviations from the “ideal” humidity can negatively impact the utilised substances and their specific characteristics as well as their potential inter-reactions during the subsequent process. It is important not only to ensure reliable quality levels, but also to keep the products consistent in terms of their pourability and flowability. This is the only way to ensure the optimal utilisation of the corresponding storage, conveying and dosing systems.

Preventing Corrosion on Pipelines

Merely due to the extensive surfaces they form, pipelines and fittings quickly become coated in condensation — all the more so at lower temperatures. This can have far-reaching consequences — and therefore prove costly. Over time, the ongoing exposure to humidity causes rust to form in the affected areas. Worse still: Depending on where the piping systems are set up, the condensed water can also drip into the production or storage containers below and cause considerable damage there, contingent on the role of the system elements in the production process. The use of dehumidification systems based on current adsorption technology guards against condensation, corrosion and mould formation, thereby preventing permanent damage to products and production facilities.

Conveyability / Pourability

Regardless of the industry, high implementation speeds, optimal coordination of the individual elements with each other and, above all, reliable functionality are essential quality features of dynamic process technology. The quality of the conveyor technology within the individual process segments plays an essential role here. To uphold this over the long term, external disturbance factors, such as high or significantly fluctuating air humidity, must be systematically excluded. Dehumidification systems based on contemporary condensation or adsorption technology provide the optimal conditions in which to do so. They ensure that condensation does not turn into corrosion on essential conveying elements, but above all that bulk materials retain their flowability and general cargo does not stick or adhere. They are therefore indispensable for the efficiency of production processes and thus also for the manufacture of competitive products.
