Technical Data Sheet

The TD-4100 XD is a ruggedized version of the TD-4100 continuous on-line oil in water monitor. The XD is designed specifically for offshore oil production, refining, petro-chemical, mining, and other industries that require robust on-line hardware for severe duty and hazardous area locations. The monitor is skid mounted and constructed of 316 stainless steel, including an external keypad, for operation in corrosive environments. The TD-4100 XD detects and measures crude oil, refined fuels, fuel oils, lubricating or hydraulic fluids, and aromatic solvents in water. Detection limits range from low ppb (µg/L) to high ppm (mg/L).

Why Continuous On-Line Monitoring?
Continuous on-line monitoring provides the most responsive feedback loop for measuring hydrocarbons in water. Continuous monitoring is reliable, effective, and recognized for its ability to improve process management for treating, discharging and detecting hydrocarbons in water. Compared to laboratory grab sample analysis, on-line monitoring provides cost effective, continuous, remote, operator unattended measurement of aromatic hydrocarbons in water.

Features of the TD-4100 XD

The Unique Flowcell. The TD-4100 XD does not have a glass flow cell. Hydrocarbons are detected in a stream of water which falls through an open chamber; the stream does not contact, dirty or foul the optical windows used for monitoring aromatic hydrocarbons. A proprietary Air Curtain system keeps optical windows fog-free in humid environments or hot water applications.

Hazardous Area Locations. The system is easily configured for hazardous area locations: Class I Division I and Class I Division II.

Low Maintenance. There are no tubes, pumps or valves to replace. The system's one moving part has a life expectancy of greater than 5 years. Routine maintenance involves changing a lamp twice a year and an air filter periodically.

Direct, Continuous Monitoring. The TD-4100 XD monitors a flowing water stream continuously. No chemicals, no pre-treatment and no
manual manipulation of the sample are required to monitor aromatic hydrocarbons.

Accurate. The TD-4100 XD directly measures aromatic hydrocarbons in water with accuracies that consistently correlate to regulated laboratory methods.

Sensitive. BTEX, gasoline, diesel, jet fuel, crude oil, aromatic solvents and refined petroleum products containing aromatics are detected by the TD-4100 XD from low ppb (ug/L) to high ppm (mg/L). For example, the TD-4100 XD can detect 5 ppb of gasoline or diesel fuel in water free of interfering compounds.

Selective. The TD-4100 XD continuously measures the fluorescence of aromatic hydrocarbon compounds in water. Fluorescence occurs when a molecule absorbs light energy of one specific wavelength and emits light energy of a longer wavelength. Fluorescent compounds each have a unique signature and these compounds can be displayed as an actual concentration.

Effective Monitoring in Dirty Water. Monitoring fluorescence makes the TD-4100 XD resistant to interferences by turbid or dirty water which impact on-line UV or IR light scatter instruments. Most substances absorb light, but very few fluoresce; if a substance does not fluoresce at specific wavelengths for the monitored aromatic hydrocarbon, it will not interfere.

Operator Friendly. The TD-4100 XD is designed for easy operation. Simple on-board software controls alarms, 4-20 mA output, diagnostics, and calibration.
