Model 204 – Sample Transfer
Stripper™ (STS) Patented PRINCIPLES OF OPERATION:
Click for a diagram The ASI / KECO Series 204 incorporates basic principles covered by patent 5,398,559 and patents pending. A liquid or gas sample is allowed to continuously flow past one side of a non-selective permeable membrane while a carrier gas, hydrocarbon-free air, continuously flows past the other side of the membrane. Sample components permeate the membrane and are swept away to make a mixture of gases suitable for analysis. An exclusive & patented liquid Validation System is available as an option. Texas Commission on Environmental Quality (TCEQ) has designated the Model 204 as “Best Available Control Technology” and “Equivalency” for continuous monitoring of cooling tower waste water applications. In addition, Shell Global has awarded us Preferred Vendor. FEATURES:
TYPICAL APPLICATIONS Hydrocarbon VOC in Water - Model 204-V:
·
Hydrocarbons in Cooling Tower
Water
Leaks of hydrocarbons from heat exchangers can emit large
quantities of Volatile Organic Carbons (VOC). This can be a hazard
from a flammability standpoint as well as cause emissions into the
atmosphere. On-line continuous monitoring can pay for an analyzer in a
short time by warning of corrosion leaks. Savings in lost product and
laboratory time can be substantial.
·
Hydrocarbons in Wastewater
Where the dissolved hydrocarbon or oil content could be
PPBw, PPMw, or at saturation levels, Model 204 easily provides
continuous measurement online. This includes current applications for
wastewater effluent monitoring.
·
Leaks from Heat Exchangers
Monitoring for hydrocarbon in cooling water or condensate
allows the earliest warning of developing leaks. Maintenance can be
scheduled in advance of costly equipment failure when leakage rate
data is used for forecasting purposes. Boiler feed water monitoring
for hydrocarbon, from heat exchangers can prevent power generation
equipment damage.

Storm Runoff Water
·
Ground water recovery sites
·
Boiler condensate and power plant cooling water reclaiming
systems
·
Intake monitoring for Desalination plants
·
Water discharge in municipal water treatment systems
·
Engine cooling water
·
Effluent monitoring Oil in Water - Model 204-O:
·
Bilge
water discharge monitoring
·
Oil in Wastewater
Where the dissolved oil or hydrocarbon content could be
PPBw, PPMw, or at saturation levels, Model 204 easily provides
continuous measurement online.
·
Oil in produced water
The Model 204 can continuously monitor the discharge of
produced water as required by the Environmental Protection Agency
(EPA). The EPA requires that produced water discharge must contain a
concentration of less than 29 ppm oil and less than 42 ppm grease for
a 30 day average and daily maximum.
·
Oil in Cooling Water and Holding Ponds
Equipment leaks, spills, and drainage run-offs can cause
build-up of hydrocarbon in the water. The Model 204 can give a
continuous online indication of the volatile organic carbon (VOC) /
oil contained in these waters.
·
Fuels in Storm Runoff Water
·
Phenol in water
The Model 204 can continuously monitor the cooling water
to detect a leak and prevent a discharge violation
·
Hydroelectric dam sumps
·
Drain systems for fuel oil storage tank area
·
Ground water recovery sites
·
Boiler condensate and power plant cooling water reclaiming
systems
·
Intake monitoring for Desalination plants
·
Engine cooling water
·
Effluent monitoring * Measurement of Volatile H/C's from Hydrocarbon Gas Streams, Hydrocarbon Liquid Streams, Aromatics, Alcohols, oils, and Paraffins in Water Streams. For many of these applications, a readout able to identify hydrocarbons is required such as a GC. HYDROCARBONS IN COOLING TOWER WATER Leaks of hydrocarbons from heat exchangers can emit large quantities of Volatile Organic Carbons (VOC). This can be a hazard from a flammability standpoint as well as cause emissions into the atmosphere. 99.9 to 100% of VOC are stripped to the atmosphere in cooling towers and have been found to be 12,576 pounds per day from a single exchanger. On-line continuous monitoring can pay for an analyzer in a short time by warning of corrosion leaks. Savings in lost product and laboratory time can be substantial. Hydrocarbon in Cooling Water
Fortunately, airflow through a cooling tower dilutes the hydrocarbon, allowing higher concentrations than shown on the right column before the cooling tower catches fire. A typical cooling tower with 10 PPM by weight hydrocarbon content will emit 15,000 lbs./day lost product.
