  Spray tower scrubbers are among the simplest and most versatile wet pollution-control technologies used in industrial air-treatment systems. They bring contaminated gas into contact with droplets of water, solvent, or chemically reactive scrubbing liquid, allowing particulate matter and selected gaseous pollutants to be captured or absorbed. The new book Spray Tower Scrubbers: Design, Operation, Pollution Control, and Practical Engineering Applications by Charles Nehme presents the technology from a practical engineering perspective, covering equipment configuration, spray-nozzle selection, gas-liquid contact, pollutant removal, mist elimination, liquid recirculation, corrosion considerations, operation, maintenance, troubleshooting, and industrial applications. Why Spray Tower Scrubbers Matter A spray tower generally consists of an open chamber containing spray nozzles through which the scrubbing liquid is distributed. In a common counter-current arrangement, contaminated gas...

  Modern commercial cannabis facilities are far more demanding than conventional warehouses or commercial buildings. HVAC systems must maintain carefully controlled temperature, humidity, airflow, and environmental stability while responding to changing plant conditions, lighting schedules, irrigation, and room operating modes. My new book, Psychrometric Analysis and Equipment Selection for Large-Scale Commercial Cannabis Facilities , focuses on the HVAC engineering principles needed to approach these environments systematically. View the book on Amazon Why Psychrometrics Matters in Cannabis Facilities Psychrometrics provides HVAC engineers with a practical framework for understanding the relationship between air temperature, moisture, dew point, humidity, and other air properties. These relationships are particularly important in controlled-environment agriculture, where moisture management can become one of the most challenging aspects of HVAC operation.

  Large cold-storage logistics hubs are among the most demanding refrigeration environments in modern industry. They operate continuously, consume substantial electrical power, and must maintain tightly controlled temperatures regardless of outside conditions, loading activity, product movement, or electrical-grid constraints. Traditionally, refrigeration systems have been designed to respond directly to the instantaneous cooling load. But what if cooling could be produced when electricity is favorable, stored for later, and released when refrigeration demand or electrical prices are highest? That is the fundamental opportunity presented by sub-zero thermal energy storage (TES) . Using encapsulated phase-change materials (PCMs), modern TES systems can store significant quantities of cooling energy at temperatures appropriate for refrigerated and frozen logistics applications. Why Cold-Storage Facilities Need Thermal Flexibility A conventional refrigeration plant has limited flexibi...
