It is essential that heat transfer systems for chemical processes are designed to maximize efficiency. Because the heat transfer step in many chemical processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily.
The transfer of heat from one fluid to another is an essential component of all chemical processes. Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or to heat components before starting a reaction to make a final product, the thermal processing operation is core to the chemical process.
In the ever-evolving consumer economy, new technology is regularly transforming communication between buyers, sellers and manufacturers. In the consumer marketplace, buyers have unprecedented access to nearly any product imaginable.
A typical control approach for an industrial fired heater uses global measurements to keep the system efficient and within safe operating limits. Differences in combustion stoichiometry between individual burners, however, can cause global measurements to produce an incomplete picture of the combustion taking place within the heater.
Fluid-bed dryers offer an inherently efficient method of moisture removal that has not changed since the systems were developed in the 1950s. The introduction of ever-improving control technologies — personal computer-based and PLC control systems, smart sensors and other technological advances — in the last 40 years, however, has changed how process engineers operate their fluid-bed drying systems.
Rapid growth and innovation in the past decade have enabled companies to implement key technologies to monitor, analyze, control and automate their assets. Wireless resistance temperature detectors, or wireless RTDs, have bridged the gap from decades of hardware to remotely connected devices.
Multi-gas detector can simultaneously detect up to seven gases including, flammable gases, vapors and oxygen. It is suited for use in chemical, oil and gas, mining, pharmaceutical and water treatment applications.
Turbo-Dryer can be used to dry water-wet or solvent-wet materials through a wide temperature range without the need for vacuum. The gentle material-handling features and low exhaust velocities of the continuous, rotary tray dryer reduce fines formation and carryover in the exhaust.
