TD-4100 XD Oil in Water Monitor

An Overview

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.

Technical Data Sheet

TD-4100XD Ruggedized On-Line Monitor

United States Coast Guard (USCG) Certifies the TD-4100 and TD-4100 XD for 15 ppm Bilge Alarm Monitoring

July 1999 - The USCG certified both the Turner Designs TD-4100 and TD-4100 XD on-line oil in water monitors as Oil Content Meter – 15 ppm bilge alarms. The USCG certifies that the oil content meters comply with the 15 ppm bilge alarm regulations stipulated by regulation 16(5) of Annex I to Marpol 73/78. This certification package comes on the heels of the Canadian Coast Guard Certification of the TD-4100 as a 5 ppm bilge alarm that was issued in January 1999. The USCG certification lead to an immediate American Bureau of Standards (ABS) approval letter for the TD-4100 XD deployment on an ABS classed vessel.

"The TD-4100 series non-fouling detection technology finally solves the marine industry’s expressed concern that traditional oil in water monitoring technology is simply unreliable" said Mark Uhrich, Director of Sales and Marketing. "The TD-4100 series oil in water monitors repeatedly demonstrate low maintenance performance enjoyed by the oil & gas industry for offshore platforms, FPSO’s, FSO’s and drilling rigs. Now with USCG certification the marine industry can significantly improve their bilge water discharge programs."
