Howe baker heaters are designed to heat a process fluid passing through a manifold coil 'indirectly' using a common bath of water or water glycol mixture. This ensures uniform and safe operation avoiding hot spots where the process fluid could be degraded or cooked.

Howe Baker heaters are designed according to API 12K and feature an expansion tank to absorb excess water pressure, which can be caused by thermal expansion.


  • Crude oil preheat to separators or desalters
  • Crude oil preheat between head and pipeline
  • Heating gas from the well to prevent hydrocarbon hydrate formation
  • Fuel gas dew point control systems associated with gas turbine power plants
  • Heating high pressure hydrocarbon gas streams at pressure reduction stations
  • Liquid/gas vaporisation.
  • Reboiler and stabiliser process heater

Howe Baker supports its clients with a full range of gas/oil/water separation solutions. On platforms, floaters and onshore sites Howe Baker is able to supply the complete separation process from high pressure separation up to treatment of the produced water. In its more than 25 years of experience, Howe Baker has designed and supplied well over a thousand separators up untill now.

Having manufactured and installed many of the world’s largest and most complex flare systems, Howe-Baker has consistently shown the ability to satisfy any customer requirement.  In addition to standard utility flares, Howe-Baker offers a comprehensive selection of smokeless flares for new installations and retrofits including steam-assisted, gas-assisted, high-pressure/low-pressure, stage, sonic ground and enclosed models.

Howe-Baker manufactures flares for numerous applications including refineries, petrochemical and gas plants, offshore platforms, pulp and paper mills, landfills and food processing plants.

Howe-Baker also offers comprehensive engineering services to design, build and erect multi-million dollar flare projects.  Howe-Baker systems include self-supported, guy-supported and derrick-supported flare stacks as well as offshore boom-mounted flares, portable flares and demountable flares.

Howe-Baker also has the ability to develop specialty flares for custom applications.  For example, Howe-Baker accepted an industry challenge to develop a crude oil flare which could substantially reduce pollution by decreasing the level of smoke and hydrocarbon fallout produced during offshore well testing.  The result was the introduction of the Howe-Baker Flare, rated  more than 99.99% efficient by independent industry testing firms.

Auxiliary flare system equipment available from Howe-Baker includes purge reduction devices, liquid seals, knockout drums and the most reliable pilot ignition systems.  Howe-Baker also refurbishes existing flares and provides spare parts for their flare equipment and that of other flare manufacturers.

Howe Baker Coalescing filter has an ideal performance where the maximum possible separation of liquid particles (varying from mist to sub-micron in size) from a gas stream is required.

The typical applications of the coalescing filters are:

  • To remove all contaminates from fuel gas for gas turbines
  • To remove lubricating oil mist from gas compressor discharge stream
  • To remove sub-micronic solids and lubricating oil which could damage the formation in gas injection systems
  • To protect solid desiccant or molecular sieve beds
  • To separate lube oil from propane in propane refrigeration system

The ImMax IGcell technology is an impeller type induced gas flotation system which is used for oily water treatment removing oil from water, such as refinery effluent, desalter effluent, condensate, cooling water and produced water for both onshore and offshore applications. This system benefits from unparalleled mechanical flotation with minimal skim rate and easy maintenance.

Fluid enters the vessel through the inlet cell and passes sequentially through each of the four flotation cells. Each cell is equipped with turbine producing finely disseminated bubbles. Small dispersed bubbles of gas rising through oil/solid contaminated water and attach themselves to oil droplets accelerating their path to the surface where oil layer builds up and skimmed off.

The ReMax IGcell is a hydraulic type induced gas flotation wastewater enters the first cell, where clean effluent is injected under pressure. Inside the cell, a venturi creates a locally low-pressure area. Air/gases sucked in from above the water level in the cell and injected along with the clean effluent below the liquid level. Bubbles are thus created, to which the impurities attach themselves and float to the surface, forming a froth which is skimmed off.

Hydrogen sulphide, carbon dioxide, mercaptans and other contaminants are often found in natural gas streams. H2S is a highly toxic gas that is corrosive to carbon steels. CO2is also corrosive in the presence of water to equipment and reduces the BTU value of gas.


Our field proven gas sweetening system remove these contaminants so the gas is suitable for transportation and further use.

Howe Baker designs and manufactures a variety of gas sweetening systems, including amine systems. Howe Baker offers a number of amine solvents that remove the contaminants by chemical reaction. Custom and standard designs are available to meet any gas sweetening challenge in the industry.

Our specially engineered systems:

  • Amine contactor tower
  • Reboiler/surge tank
  • Reflux condenser/solution cooler
  • Reflux accumulator
  • Reflux pump(s)
  • Main solvent pump(s)
  • Solvent booster pump(s)
  • Full flow filter for rich solvent
  • Activated Carbon filter
  • Control panel (s)


Amine Advantages

  • Wide Range of Flexibility
  • Capable of Slipping CO2
  • Low Pressure Drop
  • Well Proven
  • Suitable For High Acid Gas Removal
Amine Disadvantages  
  • H2S Emissions
  • Amine Is Easily Contaminated
  • Corrosion From Amine Degradation
  • Complex Operation
  • High Initial Capital Cost









Howe-Baker's Approach To Desalter/Deydration Design

Howe-Baker uses the "basic engineering" approach for the design and specification of electrostatic desalters and dehydrators.  We believe that if the problem is well defined and the surrounding circumstances recognized, then the proper equipment, using the correct safety factor, can be specified. 

Figure 1figure1

One-stage Operation

Dehydration (Figure 1) – Single stage units are usually sufficient for dehydrating produced crudes. BS&W carryovers can range from trace to 1.0 volume percent, depending on crude type, operating temperature, inlet water content and other factors.  "Other factors" include production methods, chemical treatments, handling procedures. Etc.                

Desalting (Figure 2) – Adding water which is less saline that the water contained in the feedstock crude converts and hydrator into a desalter. 


Figure 2

Figure 3figure3

Typical single stage removals are illustrated in Figure 3.


Two-Stage Operation

Dehydration/Desalter (Figure 4) - First stage reduces B. S. & W. content so that water added for desalting can dilute more effectively.


Figure 4

Figure 5figure5

Desalter/Desalter (Figure 5) - Two stage desalting is required when 90-95% salt removal is not good enough. Process water is injected into the second stage and recycled back to the First. 98-99% salt removals can be expected for most crudes.


Three-Stage Operation

Dehydration/Desalter/Desalter (Figure 6) – This design is appropriate when feedstock BS&W are high (say 5-40 volume percent) and product salt content must be low (2 ptb). The dehydrator reduces the BS&W


Figure 6

Figure 7figure7

Desalter/Desalter/Desalter (Figure 7) - This design is rare but has been specified for applications on very heavy crudes and residua. When these oils are used as feedstock for cat crackers and turbine generators, very low sodium contents are required.
