A forced draft air cooler typically consists of a bundle of finned tubes arranged in a specific configuration. The process fluid flows through the tubes, while air is forced across the fins by fans. The heat from the process fluid is transferred to the...
A three-phase separator is a crucial piece of equipment in the oil and gas industry, designed to separate a mixture of oil, gas, and water into its individual components. The vertical three-phase separator, equipped with interface control, is a particularly efficient design for maintaining...
Sand separators are crucial components in various industries, including oil and gas, water treatment, and manufacturing. They are designed to remove solid particles, such as sand, dirt, and scale, from liquid streams. The choice of sand separator depends on various factors, including the type...
In a fixed tube sheet heat exchanger, one fluid flows through the tubes, while the other fluid flows through the shell. Heat is transferred between the two fluids through the tube walls. The tube sheets are securely fastened to the shell, providing a rigid...

Microchannel heat exchangers are a type of heat exchanger with channels that have characteristic dimensions in the micrometer range. These tiny channels offer significant advantages in terms of heat transfer efficiency and compact design. In a microchannel heat exchanger, the two fluids flow through...
If the S-Stamp is the finish line, the Authorized Inspector (AI) is the gatekeeper holding the stopwatch. Before that stamp ever touches a boiler, inspectors are verifying far more than weld quality or paperwork completeness. They’re answering one critical question:
Waste heat recovery boilers (WHRBs) capture hot exhaust gases from industrial processes or engines and use that heat to generate steam or hot water — without burning additional fuel.
A scraped surface heat exchanger consists of a cylindrical shell with a rotating shaft inside. The shaft is fitted with blades or scrapers that continuously scrape the inner surface of the shell. This scraping action prevents the formation of product buildup on the heat...
Shell and tube heat exchangers are a common type of heat exchanger used in various industries. Within this category, two primary designs stand out: floating head and U-tube. Each design has its own advantages and disadvantages, making it suitable for specific applications.
Learn how heating boilers unintentionally cross into ASME Section I power boiler classification, what inspectors look for, and how to avoid costly compliance surprises.
Two-Phase Spherical Separators operate on the principle of gravity separation. When a gas-liquid mixture enters the vessel, the heavier liquid phase settles to the bottom, while the lighter gas phase rises to the top. The unique spherical shape of the vessel promotes efficient separation...
