Hyper Thin Film Technology

All Dew Point Sensors Utilize HTF™ Technology

HTF™ Hyper-Thin-Film Al2O3 Technology

• HTF™ Technology is significantly different from conventional aluminum oxide technology

• HTF™ Sensors are rugged and specially well suited for tough applications

• HTF™ technology is field proven – in hundreds of different applications – in thousands of installations world wide

HTF™ vs. Conventional Al2O3 Technology A thinner layer, a precise barrier layer and a pore geometry, “arresting”

the Brownian motion of the water molecules, lead to changes in capacitance with changes in moisture of at least two orders of magnitude higher than that of conventional sensors.

HTF™ vs. Conventional Technology High Sensitivity Comparison

Xentaur HTF™ sensors are two orders of magnitude more sensitive than conventional aluminum oxide sensors and have a quasi linear response curve.

HTF™Advantages : Fast Speed of Response

Xentaur sensors are the fastest in the industry

Final Construction of HTF™ Sensor

- Polished Sensor

- Porous Sensor (with Sensor fitting)

Conventional Mechanical Construction

• Both electrodes are exposed to the sample, thus shorting can occur

• Aluminum base is exposed to the sample gas, thus corrosive gas constituents will attack the sensor

HTF™ Advantages: Low Temperature Coefficient

HTF™ sensors have a negligible temperature coefficient (C(t)) down to -70°C(dp).

At -80°C(dp): C(t) for HTF™technology sensors is about 0.25 °C(dp)/°C(t) C(t) for conventional sensors is about 1.0 °C(dp)/°C(t)

HTF™Advantages : High Uniformity

To assure the highest degree of uniformity possible, Xentaur HTF™sensors are produced in a robotized manufacturing system and vigorous QC procedures are applied through all phases of production.

• High uniformity means that the response curves of all sensors follow the same model

• The known shape of the response curve allows calibration strategies based on mathematical modeling.

HTF™Advantages : Long Term Stability – Field Data

Uncorrected signal response after 4 years in field service

Continued cycling of the sensor from -88C to +20 C shows good repeatability especially at the low end.

HTF™Advantages : Repeatability

HTF™Advantages : Low Deviation

PRODUCT RANGE OVERVIEW: COSA/UOP Continuous Hydrogen Analyzer

(CHA)

CONTINUOUS HYDROGEN ANALYZER

CHA II Key Advantages – Accuracy not affected by variations in the gas matrix – Sensor is inherently intrinsic safe – Sensor operates at ambient temperatures – 10 second T90’s – Very long lasting measuring cell – Negligible maintenance – Continuous Measurement

The CHA transmitter converts the millivolt (mV) signal generated by the Hydrogen Sensor into a 4-20 milliamp (mA) analog output signal. This output signal can be software configured to be equivalent to temperature compensated hydrogen measurement, uncompensated mV measurement, or RTD temperature.

APPLICATIONS

• REFINERS – Catalytic Reformers – Recycle Gas – Hydrogen Plants – PSA from Hydrocracker – Hydrogen Seperator Units

• CHEMICAL PLANTS – Polyolefin – Ethylene

• ELECTRIC POWER GENERATION • FUEL GAS STREAMS • PILOT PLANTS • LABORATORY APPLICATIONS

ISOMETRIC VIEW

The Hydrogen Sensor consists of a corrosion resistant platinum sample gas electrode, a solid polymer electrolyte, and a platinum reference electrode. This platinum/polymer/platinum layering is a symmetrical design that minimizes the temperature aging drift normally associated with this type of electrochemical sensors. Reduction of drift means that fewer instrument calibrations will be required saving considerable maintenance resource time.

CHA SENSOR THEORY OF OPERATION

The CHA Sensor physically separates two regions of different hydrogen partial pressure: Sample & Reference Gas streams

The catalytic platinum electrode on both the sample and reference gas regions of the sensor dissociates molecular H2.

The H2 protons diffuse through the polymer moving from the higher partial pressure region to the lower partial pressure region

At the same time, free electrons stripped from the hydrogen proton at the platinum/polymer electrolyte interface remain in the platinum.

Electrical junction double layer is formed resulting in a millivolt signal which is then converted to % H2

TYPICAL CHA INSTALLATION

CHA II UTILITY REQUIREMENTS

• 24 VDC Power Supply for 4-20 mA (loop powered) • Reference Hydrogen. 100% Ultra High Purity H2. Consumption

typically 25cc/min (.00089 ft3/MIN). • Calibration Gas. Use the 100% UHP H2 for one point, and one

other calibration gas for the second point. Consumption typically 250cc/min.

SENSOR LIMITATIONS • HCl, H2S, NH3 100 to 200ppm upper limit. Can

poison the sensor.

• CO 5,000ppm upper limit, but t testing taking place to increase this limit. Reversible affect.

• O2 Interferes with H2measurement. Does not damage sensor but adds to sensor output.

• Water Vapor 2000ppm upper limit. Greater levels can be overcome with proper sample system design.

Olefins Plant: Application Example When polyolefins are produced in petrochemical plants, the PP/PE resin leaves the reactor saturated with un-reacted hydrocarbons. Before this "wet" resin can be used for the production of plastic containers (i.e. bottles, food containers, etc.), it is sent to a purge bin where it is purged with nitrogen to drive off the un-reacted hydrocarbons. As a result, an off-gas stream containing nitrogen and hydrocarbons is produced. This purge bin off-gas is usually burned at the flare header. This off-gas contains a significant amount of hydrocarbons. Removing nitrogen from this stream upgrades it to fuel gas quality, so it can be used instead of purchased gas.

A small change in the BTU value of a gas can cost a significant amount of money for a large scale production facility who is

purchasing or using the gas for production purposes.

For efficiency control of devices such as turbines it is very important to have a very quick and highly accurate measurement.

MEASUREMENT PRINCIPLE:

1. Small particles which accompany natural and industrial gases pass through two laser beams focused in a pipe by illuminating optics.

2. Laser light is scattered when a particle crosses the first beam. 3. The detecting optics collects scattered light on a photodetector P1, which then

generates a pulse signal. If the same particle crosses the second beam, the detecting optics collect scattered light on a second photodetector P2, which converts the incoming light into a second electrical pulse.

4. By measuring the time interval between these pulses, τ, the gas velocity is calculated as V=S/T, where S is the distance between the laser beams.
