herminol heat transfer fluids are commonly used in offshore and
onshore oil and gas processing, fractionation, refining, transportation,
and recycling operations. Therminol 55, Therminol 59,
Therminol 62, Therminol 66 and Therminol VP1 have successfully
demonstrated low-cost, reliable, and safe performance in these applications
for five decades.
When Eastman Therminol heat transfer fluids are used within
suggested temperature limits in a well-designed and well-maintained
system, they should provide years of excellent service.
Thermal fluid in a heat transfer/coolant system can operate under
demanding conditions. The fluid can experience degradation that
results from thermal and possibly oxidative stresses. Frequent fluid
testing and analysis can:
* extend fluid performance life;
* help protect equipment, saving maintenance costs;
* help avoid unplanned downtime;
* promote safety/fire prevention; and
* conform to insurance and fire safety recommendations that may
impact insurance premiums.
Regular sampling, testing, and analysis of thermal fluid will also
satisfy recommended practices published by insurance underwriters
and fire prevention associations:
* NFPA 87, Recommended Practice for Fluid Heaters
* Global Asset Protection Services, GAP.7.1.5
* FM Global Datasheet 7-99 on Heat Transfer by Organic and
Synthetic Fluids: " 2.5.4.1 Test samples of the heat transfer fluid
for impurities and/or degradation at least yearly. "
Eastman provides heat transfer fluid testing and analysis to help
detect fluid contamination, thermal degradation, moisture, and
other issues that can help avoid corrosion, heat transfer decreases,
start-up issues, blockages, fouling, freezing, pump cavitation, fire,
and other performance issues.
Eastman provides complimentary Therminol fluid sample collection
kits. Each kit includes a collection bottle, instructions on safe
sampling, and shipping documents to return the sample to one of
Eastman's in-house ISO-certified laboratories on four continents.
There, expert lab technicians analyze each sample for key quality
indicators, and send back a detailed report with suggestions for
corrective action, if needed. The Eastman technical team will also
answer any questions that may arise.

more than an enhanced product. It also
brings clarification and new information,
says Clint Rogers, General Manager
of Cashco's Valve Division.
The ULR-1 was originally
marketed as the U1 by Kaye
MacDonald, which Cashco bought
in 1999. Unfortunately, the only
documentation for the U1 and
similar products was the original
schematics, which showed how
the tubing and fittings were to be installed,
Rogers says.
" Previously, a customer would have had
to locate the technical bulletin, work their way through its product
coder and then a separate product coder for the correct bill of materials
for the hookup, " Rogers explains. " Not any more. With these
new products, all of the information is in the technical bulletin and
the operating manual. "
As Rogers explains, the ULR-1 is a DA4 regulator with a Cashco
Cashco ULR-1
CA1 back-pressure valve mounted onto it. Using the inlet pressure
from the valve, the CA1 is set to control the outlet pressure of the
main valve. Because the outlet of the CA1 constantly exhausts into
the atmosphere, the media through the valve must be environmentally
safe gas such as oxygen or nitrogen.
For even more choice in pressure regulation, Cashco has also introduced
the SLR-1 and SLR-2 Self-Loading Regulators. The SLR-1
is a high-performance, pressure-loaded, pressure-reducing regulator
with a self-contained regulator mounted onto it. Inlet pressure
from the main valve is diverted to the pilot, which, in turn, reduces
the loading pressure to the cover dome in order to maintain the set
point of the main valve. The pressure inside the dome is static, so
gas is only released to atmosphere when the outlet pressure setting
is reduced or the system is shut down.

The new SLR-2 self-loading regulator is similar to the SLR-1,
but its loading valve is not self-relieving. Instead, the cover dome
bleeds through a filter and check valve back into the outlet of the
main valve. This feature allows the SLR-2 to be marketed for hydrogen
gas, natural gas and sour gas (NACE) applications.
