S occurs abundantly in the world’s fossil fuel reserves. The sulfur recovery unit (SRU) of a refinery is dedicated to processing the H

TLG-837 Analyzer Unit Overview

The analyzer unit contains all of the system’s electronic components.

I/O board

-power supply nova II™ spectrophotometer fiber optic cables

nova II™ Spectrophotometer

The core component of the TLG-837 Analyzer is the nova II. This device connects to the sample flow cell via fiber optic cables, continuously pulsing a white light signal through the sample fluid and measuring absorbance in the returned signal.

Human Machine Interface

The TLG-837 is controlled by an industrial computer operating on the proprietary ECLIPSE™ runtime software. The touch-screen

LCD displays real-time H

2

S concentration and any additional measured parameters with access to system settings.

Communication Electronics & Power Supply

The standard TLG-837 is equipped with 1 galvanically isolated 4-20 mA analog output per measurement and 3 digital outputs.

Additional communication protocols can be specified by the customer (inquire for available options).

Fiber Optics

The continuously drawn process sample circulates through the flow cell disk in the probe as the fiber optic cables transmit the light signal through the flow cell path length and back to the nova II spectrophotometer.

[4]

Optical Assembly & Principle of Operation

The nova II Spectrophotometer measures the absorbance in the sample. This device is normally mounted inside the TLG-837 analyzer enclosure and transmits a light signal to and from the sample flow cell via fiber optic cables. The nova II housing contains the light source as well as the detector hardware.

xenon light source holographic grating fiber optic cables steam tracing flow cell disk o-ring cooling extension collimator diode array

The nova II measurement cycle is virtually instantaneous thanks to the speed of light. For explanatory purposes, it helps to break the cycle into stages:

(1) The white light signal originates in the pulsed Xe lamp that functions as the light source.

(2) The signal travels via fiber optic cable to the flow cell disk in the probe. A collimator narrows the light beam.

(3) The signal travels directly across the optical path inside the flow cell disk, interacting with the continuously drawn tail gas sample molecules.

(4) The signal exits the flow cell disk through a collimator, now containing the distinct absorbance imprint of the current chemical composition of the tail gas.

(5) The signal travels via fiber optic cable to the nova II.

(6) The signal is dispersed by the holographic grating. Each differentiated wavelength is focused onto a designated photodiode within the diode array. Much like sensors in a digital camera, each diode records the light intensity at its assigned wavelength. The nova II provides this rich data to the HMI for real-time visualization of the absorbance spectrum.

[5]

The in situ DEMISTER Probe

Applied Analytics’ patented TLG-837 DEMISTER Probe is mounted directly on the process pipe. The physical measurement occurs inside the probe head, minimizing the sample transport time. Entrained sulfur vapor is removed from the sample as an internalized function.

This probe was designed to be lightweight and compact, so it’s easy to install and service by a single technician.

Probe Retractor

Allows easy removal by hand or power drill.

Probe Head

Automatic Sulfur Removal

Tail gas contains elemental sulfur which is quick to condense and plug mechanical cavities or obstruct optical signals. Online analysis of tail gas requires a sulfur removal mechanism in order to operate at all.

The DEMISTER Probe actively removes sulfur from the rising sample as an internalized function within the probe body. Recycling the steam generated by the Claus process, the probe controls the temperature along its body at a level where all elemental sulfur vapor in the rising sample condenses and drips back down to the process pipe. The sample that reaches the optical measurement cell in the probe head is virtually sulfur-free, posing no threat of plugging, freezing, or interference.

Innovative Sulfur Removal Principle

Inside the probe, an internal ‘demister’ chamber

(concentric to the probe body) is fed with low pressure steam (see

E

&

F

). Since the LP steam is much cooler than the tail gas, this chamber has a cooling effect on the rising sample.

Elemental sulfur has the lowest condensation point of all of the components in the tail gas. Due to the internal probe temperature maintained by the LP steam, all of the elemental sulfur in the rising sample is selectively removed by condensation while a high-integrity sample continues upward for analysis in the probe head.

J

The In Situ Measurement

The point of interaction between the light signal and the sample gas occurs directly in the flow cell disk inside the probe head (

C

&

D

). The flow cell disk has a built-in high pressure steam channel (

A

&

B

) to heat the cell and ensure that any present sulfur remains gaseous—eliminating the possibility of condensation on the optical windows.

The Sample Return

An aspirator (

G

) creates a Venturi effect which pulls the sample up the probe body intake path, through the flow cell for analysis, and down the return line. The used sample is released back into the process pipe (

H

).

The World’s Safest Tail Gas Analyzer

Applied Analytics design centers on inherent safety. The major safety flaw of other tail gas analyzers is that they bring the toxic sample fluid into the analyzer enclosure for analysis. Not only does this practice expose the system electronics to higher corrosion effects, it also poses a lethal threat: if there is any leak in the instrument — especially inside a shelter — the human operator is placed at enormous risk.

The key difference between the TLG-837 and other tail gas analyzers is the use of fiber optic cables: we bring the light to the sample instead of bringing the sample to the light.

The toxic sample only needs to circulate through the probe, and never enters the analyzer electronics enclosure.

Tail Gas Analysis by nova II Spectrophotometer

A conventional photometer measures a chemical’s absorbance at one pre-selected wavelength with one photodiode. This is known as ‘non-dispersive’ spectroscopy because it uses an optical filter or line source lamp to remove all wavelengths but the preselected measurement wavelength.

The nova II Spectrophotometer acquires a full absorbance spectrum using an array of 1,024 photodiodes. Each one of these diodes is assigned by the firmware to register light intensity at one specific energy (wavelength). This is known as ‘dispersive’ spectroscopy because the each wavelength of light is measured individually and no data destruction occurs.

In the nova II, a full 200-800 nm UV-Vis absorbance spectrum is produced at 1 nm resolution:

THE DIODE ARRAY

200 nm

300 nm

UV

400 nm 500 nm

For tail gas analysis, the UV range of the full spectrum is utilized, while the remainder of the spectrum is very useful for reference wavelengths, background correction, and more.

» Ethernet interface for remote access

[9]

Collateral Data

Any single photodiode measurement is vulnerable to noise, signal saturation, or unexpected interference. This susceptibility to error makes a lone photodiode data point (as used by a photometer) an unreliable indicator of one chemical’s absorbance.

As accepted in the lab community for decades, the best way to neutralize this type of error is to use collateral data in the form of

‘confirmation wavelengths,’ i.e. many data points at many wavelengths instead of a single wavelength.

Consider the example of measuring SO

in tail gas:

In the figures above, each diamond represents a single photodiode and data point. The nova II registers absorbance at each integer wavelength within the 265-295 nm measurement range and produces an SO

2 on a full spectrum of pure SO

2

absorbance curve. After being calibrated

, the TLG-837 knows the absorbance-concentration correlation for each measurement wavelength; the system can average the modeled concentration value from each wavelength to completely eradicate the effect of noise at any single photodiode.

The TLG-837 visualizes the SO

2

absorbance curve in this manner and knows the expected relation of each data point to the others in terms of the curve’s structure. This curve analysis enables the system to automatically detect erroneous results at specific wavelengths, such as when a single photodiode is saturated with light. The normal photometer, with a single data point, is completely incapable of internally verifying its measurement.

Measuring H

S and SO

Conventional ‘multiwave’ photometers can be set up to measure multiple species. These systems are problematic because they require either (A) multiple, expensive line source lamps that emit the specific measurement wavelength for each species of analysis or (B) a rotating filter wheel which alternates the measurement wavelength by cycling between special component filters.

Neither of these solutions is ideal for tail gas analysis because of the added cost of replacing multiple lamps or maintaining a high-RPM filter ‘chopper’ wheel.

The nova II Spectrophotometer does not depend on physical wavelength isolation or any other data-destructive method; as demonstrated in the previous section, filters are applied virtually by telling the software which measurement wavelengths (i.e. photodiodes) to utilize. This allows for a solid state TLG-837 system with a single light source.

All multi-component spectroscopy depends on the principle of additivity: according to Beer’s law, the absorbance at any wavelength of a mixture is equal to the sum of the absorbance of each chemical in the mixture at that wavelength. A multiwave photometer measuring 2 chemicals will perform a rudimentary “2 equations, 2 unknowns” calculation using 2 measurement wavelengths to output the separate absorbance/concentration of each chemical.

As illustrated above, the ECLIPSE software uses the full spectrum to de-convolute the total tail gas absorbance curve and isolate each chemical’s absorbance. The TLG-837 continuously solves a matrix of equations, where each equation is supplied by a single photodiode for its assigned wavelength in the form:

A’

(x+y)

= A’ x

+ A’ y

= e’ x bc x

+ e’ y bc y

Where A’ is the absorbance at wavelength ‘, e’ is the molar absorptivity coefficient at wavelength ‘, c is concentration, and b is the path length of the flow cell. In the image above, three such equations (for 223nm, 224nm, and 225nm) are shown. In reality, the matrix includes one equation from every single integer wavelength in the measurement wavelength range.

This robust calculation, performed with each single reading, uses the power of confirmation wavelengths and statistical averaging to achieve much higher accuracy in multi-component measurement.

To incorporate the optional measurements of COS and CS

2 ment of S

V

(as detailed in a later section) as well as the rarely needed measure-

(elemental sulfur vapor), these additional variables are added to each equation within the matrix. For measurement of four or more components, only high resolution full-spectrum analysis can provide the necessary collateral data for sustained accuracy.

Off-Ratio Performance

Under various upset conditions, the H

2

S / SO

2

ratio may deviate widely from 2:1 in either direction. Some modified Claus process designs, including Superclaus™, operate with a controlled ratio much higher than 2:1. A high-performing tail gas analyzer must therefore be able to remain accurate even when this ratio is well outside the expected range.

Some photometers claim good response to off-ratio conditions, but in practice are limited by the single-wavelength measurement. No single photodiode can be reliable for both high level H

2

S and low level H

2

S due of the unavoidable limits of light saturation (at too-low concentration) and over-absorbance (at too-high concentration). Additionally, the lack of confirmation wavelengths permits a noise level which cripples accuracy in certain off-ratio scenarios.

By virtue of full spectrum acquisition, the TLG-837 sustains the specified accuracy when H

ratio reaches as high as 100:1, or as low as 1:20 . This huge range makes the system robust enough for virtually any process scenario.

lighted 210-240 nm region where the cross-absorbance occurs — for accuracy in off-ratio conditions. The TLG-837 measurement is not impacted by light saturation or over-absorbance at a single photodiode because confirmation wavelengths negate this error.

In the image above, four such equations (at 216nm, 217nm, 218nm, and 219nm) are shown. In reality, the matrix includes one equation from every single integer wavelength in the measurement wavelength range.

This matrix of data from many wavelengths provides far more accurate multi-component analysis within a spectral region that has heavily overlapping absorbances from each analyte.

Temperature Compensation

A thermocouple built into the probe head furnishes a continuous reading of the sample gas temperature. The ECLIPSE software uses this value to correct for sample temperature fluctuations in accordance with ideal gas law.

[13]

Unattended Operation

The TLG-837 only requires a one-time calibration during installation. Designed for unattended operation, the system only requires

Auto Zero to maintain accuracy. This automated task normalizes the spectrophotometer reading on a zero-absorbance gas (e.g. nitrogen) on a user-scheduled basis in order to “blank” the instrument. When Auto Zero initiates, the ECLIPSE software automatically operates the SCS valves via relays to purge the flow cell with zero gas and save a new zero spectrum.

ECLIPSE normal runtime display ECLIPSE Auto Zero

In a typical usage profile, Auto Zero is set to run every 8 hours. The task requires approximately 120 seconds during which the measurement output is frozen. Under these settings, the TLG-837 can provide greater than 99.5% analyzer uptime.

Utility Control Panel [Option]

In order to regulate the pressure of the steam going to the DEMISTER Probe, the user can build their own panel or purchase the optional TLG-837 Utility

Control Panel (UCP). Standard functions of the UCP include:

» Regulates LP steam pressure for demister chamber in probe body

» Regulates HP steam pressure for flow cell steam tracing in probe head

» Provides zero gas for Auto Zero sequence

» Provides span gas in case Auto Span is desired

» Controls aspirator flow rate

» Provides steam failure blowback feature: in the event of faulty steam utilities, the flow cell disk is sealed from the sample and the cell is purged with nitrogen from the UCP

With the features above, the UCP is a standardized panel engineered for turnkey integration.

Note: no part of UCP is wetted to sample.
