DLBH-500
Dehydrator, Line and Bath Heater Glycol Additive System
Product Description and Applications
DLBH-500 is an additive system for mono- and di- and tri- glycols, including diethlyene and triethlyene glycols, which enhances their performance in applications such as the following:
- The use of monopropylene glycol (MPG) and monoethylene glycol (MEG) as heat transfer fluids in line and bath heaters
- The use of diethlyene glycol (DEG) as a heat transfer fluid in line and bath heaters
- The use of DEG as a water removal agent in natural gas dehydration systems
- The use of triethlyene glycol as a water removal agent in natural gas dehydration systems
When MEG/water or MPG/water solutions are used as the heat transfer fluid media in line heaters and bath heaters for natural gas gathering and pipeline transport systems, they must be inhibited to prevent rapid corrosion of metallic materials of construction in these systems. DLBH-500 can be used in two ways to improve the level of performance of the MEG or MPG in this application:
1. It can be used to inhibit glycol/water solutions down to concentrations as low as 30% glycol by volume. This will allow you to avoid the purchase of expensive finished heat transfer fluids by buying the appropriate glycol and inhibiting it yourself. DLBH-500 can be used to inhibit glycol/water solutions using water with up to 250ppm hardness (as calcium carbonate).
2. DLBH-500 can be used to restore or boost the inhibitor levels in heat transfer fluids already in service. If you have heat transfer fluids that have been in use in line or bath heaters for one year or longer without being tested for inhibitor depletion, send a sample to Additives Inc.’s laboratory and we will check it for you. Additives Inc. will send you a full written report of our test results and recommendations for fortifying your inhibitor levels with DLBH-500 to extend the effective service life of your fluid. Sample request forms can be downloaded from our website (www.additivesinc.com) and bottles, labels and shipping boxes can be obtained from our laboratory.
DEG can be used as a base for heat transfer fluids used in line and bath heaters. DEG extends the upper temperature limit at which the fluid can be used by virtue of its higher boiling point, but it can create pump motor electrical system overload problems when the system is started up after downtime during cold weather periods due to the relatively high viscosity of DEG. DLBH-500 also contains viscosity modifying ingredients to prevent thickening of DEG during periods of downtime during cold weather, saving pump motors, fuses, breaker switch resetting and start-up problems, in general. DLBH-500 also serves as an outstanding corrosion inhibitor or reinhibitor additive package, and it extends the service life of DEG by controlling thermal and oxidative degradation to tars and preventing “coking.”
DEG can be used as an effective water removal agent in natural gas dehydrators, but is limited to lower average operating temperatures than TEG due to its lower boiling point; however, it provides the significant advantage over TEG of a much lower tendency to absorb benzene from natural gas. Absorption of relatively high levels of benzene by TEG can make it a hazardous waste. DLBH-500 controls the thermal and oxidative degradation of DEG, extending the upper temperature limit at which it can be operated in dehydration systems by 50% or more.
When TEG is used as a water removal agent in natural gas dehydration systems, it will thermally and oxidatively degrade over time to form corrosive glycolic acids, and gummy tars and fouling coke deposits. DLBH-500 will both extend the upper temperature limit at which TEG can be used and retard the formation of glycolic acids, tars and carbonaceous coke to prolong its effective service life.
Product Specifications
As concentrated DLBH-500 Additive System: Visual Slightly cloudy, light amber liquid Specific Gravity 1.145-1.160 pH 13.0-14.0 Boiling Point 210-220ºF Blending Instructions
Charge the desired quantity of glycol to the blending tank. The glycol should be at a temperature of 45ºF or higher and should have an initial pH of 7.0-9.5. Maintain this temperature of 45ºF or higher throughout the blending procedure. Based on the quantity of glycol being treated, add 2.2% by volume of DLBH-500 while agitating or circulating glycol. Continue to agitate for 15-30 minutes after entire Add Pak content has been added. Store the concentrated additive system at a temperature above 50ºF.

Technical Support
It is always necessary to confirm that your products meet the required specifications. Additives Inc.'s laboratory and chemists are available to test any antifreeze products containing Additives Inc.'s Add Pak as a complimentary service. In this way, Additives Inc. can help you to establish or confirm your quality control and assurance program. However, we will not warranty any Additives Inc.'s product if the blending procedure is not properly followed and/or if the glycol being used contains impurities that do not allow the final product to meet the minimum ASTM standards.
Guarantee - Warranty
Additives Inc. will only warranty our products if instructions and outlined procedures are followed. We will not warranty the Add Paks if the depleted antifreeze that is being recycled contains impurities that do not allow the recycled antifreeze to meet minimum ASTM standards. It is always necessary to confirm that your product meets the required specifications using the ASTM recognized tests and standards. Should you have a problem meeting your required specifications, Additives Inc. technical personnel will test your reprocessed and reconstituted antifreeze, while you establish use levels of our products.
