Plastics Drying

Dew Point Control Ensures Product Quality and Energy Savings in Plastics Drying

Excess moisture in plastics decreases product strength and causes a poor surface finish. On the other hand, excessive polymer drying wastes energy and lowers productivity as material delay in the dryer is needlessly prolonged. Dryer dew point controls help to achieve good product quality with minimal production costs.

 

As Vaisala partners for Scotland and North England, Fluidic offer a range of reliable dewpoint measurement instrumentation.  Incorporating the Vaisala DRYCAP sensor, this ensures a reliable and stable dedicated dewpoint measurement for dry applications.

Impulse Lines

One of the difficult problems pressure transmitters face is the clogging of impulse lines – the piping or tubing used to connect the transmitter to the process. Typical blockages include solid depositions, wax depositions, hydrate formation, sand plugging, gelling, frozen process liquid plugs and air or foam pockets. This type of plugging can lead to erroneous measurement values disrupting process control and resulting in off spec product or even unsafe plant conditions.
Honeywell SmartLine ST800 Pressure Transmitters, including models STA800, STD800, STG800, & STF800 with HART or Foundation Fieldbus communications are now available with an advance diagnostic algorithm for detecting plugged impulse lines. This option provides local indication of plugging when a display is specified and remote signaling when HART or Foundation Fieldbus communications are employed.
