Chemical Processing Humidity Control
Chemical processing has a broad spectrum of applications from conveyance lines to isolation containment and fluid bed drying. The processing of chemicals frequently requires high-temperature air-streams that need to be both heated and cooled to create the desired finished product.
In this field, we have applications in accelerated drying and providing a consistent drying result to ensure the processing is maximised. Stopping the re-absorption of moisture in long-term storage to the prevention of condensation on parts used in processing, the knowledge we have can support your business.
Some of the issues that we have come across in this industry include:
- The manufacturing process can be inconsistent in drying results.
- Ambient conditions prevent production.
- The process can have a negative impact on the environment due to the amount of energy that is required.
- The reabsorption of moisture in long and short-term storage.
- Condensation control on parts cooled in the process
- Controlling steam extraction to prevent condensed water
Using our engineering expertise and skill base, we have created and implemented new processes or improved existing ones. Our belief is in order to support you, we must understand your business and process before we can develop it.
In 2012, we were approached by a customer facing a severe problem with ambient conditions that was causing an acute bottleneck in productivity.
Our investigation revealed that the main problem was the application of a direct steam injection during the manufacturing process, used to activate an adhesive and sterilise the product. Unfortunately, once processed, the product maintained this steam and when cooled, this led to condensation and moisture retention in the product.
Without a good understanding of psychometrics, the customer had employed extraction as a method of control. However, this very approach using ambient air, had led to drying times of over 5 days.
dehum proposed several innovative changes to the process, including the introduction of warm and very dry air. This keeps steam in its vapour form, meaning condensation cannot form, resulting in a completely dry process.
Removing the 5-day bottle neck from the production process has helped keep our client one step ahead of their competitors and to keep us two steps ahead of ours.
