Air-cooled Heat Exchangers

Fabsco air cooled heat exchangers (ACHX) are exchangers that use ambient air to pull heat from a liquid or gas stream.  These exchangers can be either horizontal or vertically configured, with either forced or induced draft air.  With ACHX no cooling water is required, and operational costs are lower than other types of exchangers.

Air cooled heat exchangers are primarily used in several applications, including:

  • Condensing
  • Gas compression
  • Petrochemical
  • Petroleum refining
  • Power generation
  • Refrigeration
 

Shell and Tube Heat Exchangers

Shell and tube heat exchangers are the most common type of heat exchanger in oil refineries and other large chemical processes, and are well suited for high pressure applications.  As its name implies, they consist of a shell (large pressure vessel) with a bundle of tubes inside it.  One fluid runs through the tubes, while another fluid runs around the tubes to transfer heat between the two. The set of tubes is called the tube bundle, and may be composed of either bare or finned tubes.  Fabsco manufactures shell and tube exchangers in various configurations, including U-tube and straight tube designs, single or multi-pass, and single or dual phase.

 

Brazed Aluminum Heat Exchangers

Fives has manufactured more than 10,000 brazed aluminum heat exchangers (BAHX) since 1959. BAHX's offer several advantages over conventional exchangers:

  • Compactness - 4-5x  less surface area per volume
  • Lighter weight
  • Improved behavior under cryogenic temperatures
  • Larger temperature gradients from warm end to cold end
  • High and low pressure streams can be in the same exchanger

 

 

Hairpin Shell and Tube Heat Exchangers

R. W. Holland has been manufacturing hairpin shell and tube heat exchangers since the 1970's.  This style of heat exchanger offers several advantages over conventional exchangers:

  • Operates in true counter current flow permitting extreme temperature cross
  • Economically adaptable to service differentials
  • Ideal for wide temperature ranges and differentials
 

Cold Boxes

A Fives cold box includes one or more integrated brazed aluminum heat exchanger(s) in a carbon steel casing.  These cold boxes combine brazed heat exchangers with any type of complementary cryogenic equipment, such as:

  • Knock-out drums
  • Two-phase injection drums
  • Distillation columns
  • Interconnecting piping
  • Valves and instrumentation

Selective Catalytic Reduction (SCR)

UOP Callidus SCR systems can be used to reduce NOx and CO from a wide range of combustion and process emission sources, helping meet environmental and regulatory goals. Computational Fluid Dynamics (CFD) modeling is used on each project to guarantee system performance.

UOP Callidus can provide total system packages, including process gas conditioning, emission reduction, and post process gas heat recovery.

 

API Process Heaters

Tulsa Heaters Inc. (THI) designs and manufactures process heaters and waste heat recovery units in accordance with API Standard 560. Applications include:

  • Crude Heaters
  • Vacuum Heaters
  • Hot Oil Heaters
  • Regeneration Gas Heaters
  • Reactor Feed Heaters
  • Reboilers
  • Multi-cell Reformer Heaters
  • Delayed Cokers and Visbreakers

THI also offers complimentary equipment, including air pre-heat systems, burner management systems (BMS), and post combustion emission controls (i.e. SCR).

 

Non-API Heaters

Tulsa Heaters Midstream (THM) offers custom engineered process heaters for various applications where API Standard 560 is not required. These heaters are used in various applications, such as gas processing plants for hot oil heating and regen gas heating.

The THM standard offering uses ultra-low NOx technology, helping meet environmental and regulatory needs. Heaters are designed as modular units to facilitate faster and easier installation.
