KnightHawk Technology Products

In addition to our engineering services, KnightHawk has developed and patented technology products for two very specific processes: tube and shell transfer line heat exchangers and slag crushers.

KHE Intrabody Flow Distributor

KnightHawk has performed many failure analyses on transfer line exchanger applications. One common root cause has been poorly distributed flow in the inlet cone. Poor flow distribution can lead to Erosion, Fouling (Coking) plugging the tubes prematurely, Film boiling or Blistering. KHE has developed a proven methodology for analyzing these type problems to determine the root cause, but more importantly, KHE has developed a solution for most of these problems with an engineered product.

PE ArkansasThe Intrabody Flow Distributor is an engineered product which is custom designed for each transfer line exchanger application. Through the use of proprietary numerical analysis, we can solve your hot end problems by evenly distributing the flow across the tube sheet, which will eliminate most of the conditions that lead to erosion, corrosion, fouling and film boiling. The IFDs are constructed of high temperature cast alloy in order to survive the environment in the exchanger inlet. Our special slip joint anchor bolt design allows for thermal growth and eliminates fatigue concerns.

Key Benefits

  • The IFD solves problems related to uneven flow distribution in the inlet cone.
  • Constructed of high temperature cast alloy to survive the environment in the inlet cone.
  • Special slip joint anchor bolt design allows for thermal growth and eliminates fatigue concerns.

Crusher for Slagdownload presentation

KnightHawk designs, fabricates, and delivers high pressure/high temperature sealed crushers for custom applications. The key to our successful application is our approach to equipment design. The one size fits all approach doesn't work in this area.

For effective crusher design, one must consider, in detail, the material to be crushed. It must be evaluated based on material properties including, but not necessarily limited to, hardness, brittleness, moisture content, and compressibility.  The material must be tested in advance to ensure that the crusher will work properly the first time. Additionally, the size of the feed and the discharge requirements must be evaluated.

EZ De Coke patent pendingdownload presentation

KnightHawk has performed many failure analyses on heat exchanger applications. One common root cause has been fouling due to coke build up plugging the tubes of Transfer line Exchangers in ethylene plants. KHE has developed a proven methodology for slowing the buildup of coke and improving the efficiency of removal of the coke as well as lengthen run times between de-coke efforts and reduce damage caused by de-coke efforts. KHE has developed a solution with an engineered product. EZ De-Coke is an engineered coating which is custom designed for specific high temperature applications.

  • Longer run times between De-Coke procedures.
  • More on line de-coke cycles before mechanical de-coke required.
  • Can remove coke with a pressure washer instead of more rigorous methods that can damage the refractory and tubesheet.
  • Easier removal of coke reducing down time.
