There is a need for hot water in virtually all food, chemical and industrial process plants. From clean in place (CIP) hot water and sanitizing to paper mill whitewater heating applications, hot water plays a critical role in process sanitation and performance. 

Scraped surface heat exchangers can provide thermal treatment for products such as viscous foods and slurries, which have a high fouling potential. A common type has rotary scrapers within a tube, but several designs variations are offered by different manufacturers.

A Mexican orange juice producer ordered a complete pasteurization system that uses an electrical heating method. The system from HRS Heat Exchangers maintains the properties of freshly squeezed juice — properties that are adversely affected during traditional pasteurization processes, says the company.

The inaugural Process Heating & Cooling Show will feature the latest industrial processes, products and emerging technologies across all process manufacturing industries. Held June 16-17 in Rosemont, Ill., this interactive two-day event is designed to inform and inspire everyone involved with process heating and process cooling systems.

The handling of bulk solids has been tossed around for decades — literally. From fertilizer to food products, sugar to sludge pellets, and coffee to catalysts, the practice of heating, cooling or drying has been a part of virtually every industry built around free-flowing materials since the Industrial Revolution.

As I write this commentary, the world is facing the effects of the COVID-19 pandemic. At times, it seems the news will never improve. While I cannot predict when the headwinds will turn in our favor, I can share what has been helping me.

In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different.

Among the most common types of heat transfer equipment used in industrial applications are the various configurations of shell-and-tube heat exchangers. Suitable for a range of pressure and temperature conditions, shell-and-tube heat exchangers can be robust enough to handle corrosive or even lethal fluids.

Trent Ogilvie, president of Rockwool North America, will retire after 25 years of leading the company. According to the maker of stone wool insulation, Ogilvie built up the North American business from a small, unprofitable operation with 60 employees in 1995 to one with 1,000 employees and sales in the several hundred-million-dollar range today.

Aside from simple blending processes, most chemical processes involve a temperature change in one way or another. For example, products may need to be heated to facilitate a reaction, or cooled to control reaction rate. Many of these applications involve using a heat exchanger to add or remove heat from the process fluid.
