A Closer Look at Counterflow Rotary Coolers

An alternative to the co-flow and crossflow coolers generally being used in ethanol applications is the counterflow rotary cooler.


An Alarming Situation

Effectively choosing among the range of alarm types allows engineers to achieve better control over process heating applications.


Applications for Direct-Contact Steam Injection

Direct-contact steam injection lends itself to many applications, including water heating, pulp and paper-stock bleaching, starch cooking and some specialty applications.


Catalyst Protection

Learn about the three main catalytic failure modes: poisoning, which is usually irreversible; fouling, which is usually reversible; and thermal degradation, which is irreversible.


Finding the Right Flowmeter for Process Heating Applications

The most important consideration in flowmeter selection is the appropriate technology. For example, some flowmeters are suitable for air and gas applications, but not useful for liquids, while others may offer the most effective solution for steam monitoring.


How to Design an Air Heater

The first step in designing an air heater is to determine the temperature and airflow needed to adequately meet the desired results. Then, evaluate your system. Here's how.


Tips for Dryer Selection

In order to select a dryer with proper diameter and length, the total moisture load to be evaporated first must be determined. Total moisture will depend on final moisture desired, ambient temperature and humidity, and the desired amount of recycle and amount of chemical heat, if applicable.
