NEWS AND LINKS

 

We invite you to enjoy an informal and informative visit to this our
Web-Site Development Page. Here you will find some NEWS and a few LINKS,
along with some concepts under development and new pages under construction.


 

Welcome to our Web-Site R&D Workshop
We hope that you will find the information provided here and throughout our web-site to be of interest to you and your associates. We will look forward to receiving your comments and suggestions. And . . . IF you are a Process or Reliability Engineer faced with heat exchanger fouling or thermal system performance problems, we hope you will benefit from this and future visits.

The FIRST INTERNATIONAL SYMPOSIUM ON INNOVATIVE APPROACHES FOR IMPROVING HEAT EXCHANGER RELIABILITY - held at the Adam's Mark Hotel in Houston, Texas on Nov. 2-4, 1998 - appeared to be a complete and total success, based upon the general consensus of the majority of participants and exhibitors, which included Advanced Heat Transfer.

PAPER / PRESENTATION AVAILIBILITY - A copy of the paper entitled "Improve Heat Exchanger Performance, Reliability and Up-Time with Self-Cleaning Heat Exchangers for Fouling Service" by Robert E. Bailie, P.E. of Advanced Heat Transfer (presented at the above symposium) is available upon request - CONTACT US. A disk copy of the PowerPoint presentation can also be provided by direct telephone request

An ATB System Life-Cycle Cost Analysis
Following the installation of an ATB System, a Life-Cycle Cost Analysis confirmed that the annual cost of fouling can equal the original cost of a heat exchanger that is faced with severe fouling problems. The solution to a costly fouling problem at a CPI facility near Victoria, Texas, involved the retro-fitting of an existing exchanger with an ATB System that yielded the following results.

Technical and Economic Parameters -
associated with this costly HX fouling problem

  • Excess heat transfer surface . . . . . .107%
  • Approx. original cost of HX . . . . . .$160,000
  • Typical average service life of HX . .10 years
  • Annual cost of quarterly outages . . .$160,000

The Solution - an on-site retro-fit project

  • Approx. installed cost ATB System . . . . $60,000
  • Estimated remaining service life . . . . . . . . 8 years
  • Projected savings over service life . . . . . .$1,280,000

In this case, while it was assumed that the loss of production costs were included in the quarterly cost of cleaning, the original cost of the equipment would be one-tenth of the cost of fouling over the service life of the equipment. The $60,000 solution to the $160,000 per year problem is now projected to yield a 2100% ROI in the remaining 8 or more years of service life.

Testimonials & Project Profiles from our "Archives"
The "testimonials" that follow are excerpts from articles written by users of the FBHX Technology in the past.

Problem: A steam-heated evaporation system recovers a volatile organic from a heavy organic solution laden with foulants.A hard black scale requires switching to redundant clean evaporators every four to five days.

Solution: An FBHX installation (as described in the complete article)

Results: The FBHX has been in service for over a year (today it has been in service for over 6 years) without any operating problems.There have been no shutdowns for cleaning tubes and no process upsets, and maintenance has been nil. A significant cost savings results from the higher recovery of acetic acid and the more concentrated residue in the bottoms. The FBHX appears capable of routine operation for at least a full year between turnarounds (and that has been demonstrated in recent years). Under the new system, the reboiler circulation rate has been constant, thus providing uniform tower operation and more total throughput.

"Fluidized bed heat exchanger eliminates reboiler fouling"

Chemical Processing - August 1992

Problem: Part of the mother liquor from the crystallization of a herbicide was recycled to reduce wastewater loading and to recover product not captured in the filters. A shell-and-tube heat exchanger was used to cool the mother liquor. Material crystallized on the tube walls. Within a few days, the heat exchangers would require cleaning. The overall heat transfer coefficient would drop from 115 clean to 60 fouled (and due for cleaning) in as little as 4 days

Solution: An FBHX installation (as described in the complete article)

Results: The fluid bed heat exchanger has operated for over 90 days without cleaning with an overall heat transfer coefficient average increased to approximately 250. The fluid bed heat exchanger has resulted in less downtime, less maintenance, lower wastewater treatment loads and improved safety. Product yields have improved.

WANTED - Joint Venture Partners
In the Cover Story of the January 1999 issue of Chemical Processing magazine - "Outlook 1999 & beyond" - INNOVATING was cited as one of the leading "Challenges for the chemical industry" (see Table 1, page 25). We firmly believe that INNOVATING with self-cleaning heat exchangers to eliminate fouling will become widely accepted when the true cost of fouling is acknowledged by on-site process and reliability engineers, despite the under commercialization and under utilization of these technologies in the past. The following is an expanded restatement of our desire to secure Strategic Business Alliances and Joint Venture Partnerships to share the benefits of these technologies, with our U.S. (Houston, TX) based operations focused on the process industries.

MORE DETAILS - about A Few Specific Applications which are awaiting Strategic Business Alliances and Joint Venture Development Programs

  • Integrated Reactor / Mixer / Heat Exchanger as recently applied to Gas Hydrate Production with a major independent oil company - The FBHX Technology offers a unique opportunity to combine fluidized bed mixing with a close-coupled heat exchanger, ideally suited to exothermic reactions.
  • Wax Laden Wastewater Recovery Systems - A proven application wherein a self-cleaning heat exchanger is combined with a conventional filter system to function as a thermal separations process.
  • Lube-Oil Dewaxing Systems - An application proven by testing with one of the world's largest oil companies over a decade ago to replace costly and maintenance intensive scraped-surface exchangers.
  • Landfill Leachate Concentrators - An application that frequently involves inorganic and organic fouling constituients, along with high concentrations of suspended solids.
  • Paraxylene Crystallization - A highly respected crystallization specialist estimated that the capital cost of a typical increment of capacity with FBHX Technology would be less than half the cost of conventional scraped-surface, BEFORE considering reduced operating and maintenance costs of the FBHX alternative.
  • Totally Non-Scaling Brine Heaters -An application to up-grade and enhance the operating reliability of MSF Evaporator Systems at Sea Water Desalination Plants
