WHY DRYING PLASTIC RESINS

NEW OMAP srl - Legnaro (PD) – Giugno 2007 - by MPR

Referring to water (in the form of humidity), plastic polymers have the capacity:

- to collect it only on their surface :

non-hygroscopic materials

- to absorb it within their molecular structure:

AIR PROPERTIES

It is the temperature at which water vapor starts condense (as liquid) on a surface at that temperature.

It represents the temperature at which the specified air would reach the saturation limit.

Practically determines the water content contained in the air (see previous table)

Lower is the dew point, lower is the water content in the air

NOTES:[1] Dried material to be handled very carefully[2] Toxic flying components when drying; required flying component condensator[3] Longer residence time may cause oxidation and/or degradation[4] Maximum drying temperature is 67°C, higher temperature degrades the material. After cooler 'MT' required[5] Soft PUR may bridge in the hopper[6] High air-flow required[7] Very high flow required[8] The material generally does not degrade[9] Maximum drying temperature is 45°C. Special post cooler required

Silica gel and activated alumina have too narrow adsorption range

Molecular sieves are operating up to 90°C (@ reduced efficiency)

Due to the low throughput the material suffers from severe oxidisation which turns the material yellow causing a potential reject situation.

Benefits of New Omap WDS Dryer 1. New Omap dryer uses half of the Energy against the Motan and due to the improved design allows a reduction in drying

time. 2. The material is also being dried to the recommended moisture content levels which is a facility we currently do not have for

engineering materials. The Industrial guard should be running with a minimum 75 kgs dryer. 3. The dryer can be used on small throughput jobs which will not degrade the material as a result of the RCE function. 4. The RCE function, once activated can reduce the power consumption down to 0.9 kW/hr. 5. The dryer does not require compressed air. 6. An electronic timer is built into the dryer enabling the drying operation to commence on a Monday morning rather than being

started manually.


NEW DEVELOPMENTS

Compact Honeycomb Dryer: New Omap is developing a new series of compact honeycomb dryers, WDA series, that will be used for small capacities, where the dryer will be fixed directly on the hopper structure. The units will be fitted on hoppers range of 30-100 litres and it has been designed to perform process airflow ranging from 10 to 30 m3/h The project is foreseen to be completed by end of year 2014

COMPRESSED AIR

DRYERS

“AD-ADK” SERIES

NEW OMAP srl - Legnaro (PD) – December 2013, by Massimo Rubbis

The development of the first compressed air dryers started at the beginning of 90’s. The idea to use compressed air for drying, comes from the fact that compressed air is present in each plastic processing factory and it is also already partially dried. Compressed air when expanded at atmospheric pressure results having a lower dew point than when compressed. This effect can be used to dry polymers.

Compressed air is like a damp sponge. When compressed, it does condense moisture which is then lost in the compression phase.

By releasing (expanding) it, it increases the ability to absorb further moisture and compared to the initial phase the amount of moisture is greatly reduced.

Diagramma di f lusso schematico serie ADKAir- f low schematic diagram for ADK dryers

M. Rubbis - 10/ 12/ 2011


In literature: values ranging 0.08 and 0.22 kWh/m3. The lowest value for the latest generation of compressed air generating systems (sophisticated solutions)


ENERGY CONSUMPTION?

Energy cost to produce 1 m3/h of compressed air.

This parameter depends on the type of compressor used, with inverter or not, with energy recovery system, pipeline leaks and other conditions. It is a great variability which is not easy to evaluate.

Example:

Twin tower desiccant dryer DE20MT-55 (operating at an average of -40°C dew point, airflow 80 m3/h): 1.72 kWh @ 80°C. Considering a capacity of 7.5 kg/h PA 0.229 kW/kg

Compressed air dryer ADK50 (-50°C dew point, installed 1 kW): assuming an average real value of 0.15 kWh/m3, max airflow 16 Nm3/h: 1.0 + 0.15/16 = 1.00938. Considering 7.5 kg/h PA 0.135 kW/kg.

It should be noted, however, the randomness assumption of the cost of compressed air! It is emphasized, however, that the solution is energetically advantageous for systems with hopper up to 50-100 liters.


COMPARISON EXAMPLE OF ENERGY CONSUMPTION

Basic version AD:

• models with drying hoppers of 5, 15, 30, 50 dm3

• drying performances with dew point values from -20°C (value depending on the performances of the compressed air system)

Version ADK by adding the “Extra Drying Kit”

• Same hopper sizes

• drying performances down to -50°C dew point

All versions are designed for installations directly on machine throats and for small-medium throughputs.


COMPRESSED AIR DRYERS “AD/ADK” SERIES

The electronic control allows an easy programming thanks to the internal data-base of the main materials, with the possibility of free setting of the data by the operator



The electronic control allows to adjust the compressed air flow as function of the hourly capacity and type of material that, in combination with the anti-stress system reducing the thermal load, automatically reduces the consumption and therefore the risks of thermo-oxidative degradation.
