  • Page 8: Introduction

    AMETEK ASOMA 682T-HP Series On-Line Analyzer. Please read the entire manual before operating. AMETEK recommends that each on-line analyzer have a record book. If company policy allows, please start a loose leaf or other notebook where records of the instrument operation can be recorded.

  • Page 9: Safety

    Safety The AMETEK ASOMA 682T-HP Series is constructed with the best safety considerations in mind. Although this analyzer is designed to operate in hazardous environments, the integrity of the purge must not be compromised.

  • Page 10: Possible Hazards

    Do not reinstall the cell unless the unit is in a non- hazardous area. Theory of Operation The AMETEK ASOMA 682T-HP Series is designed for continuous monitoring of total sulfur in liquid process streams. X-ray Transmission (XRT) or Absorption (XRA) measures the change in X-ray intensity as the X-rays pass through your product.
  • Page 11 Chapter 1: Introduction, Page 4 Measurement takes place through the flow cell. The flow cell section of the pipe is a two-inch diameter stainless steel tube with proprietary “windows” specially coated to eliminate erosion. These windows, positioned opposite each other and aligned with the source and detector, are highly transmissive to X-rays and able to withstand high pressure and temperature.

  • Page 12: Overview

    The 682T-HP provides continuous, reliable detection of sulfur at pressures up to 35 bar (508 psig). It can operate either as a stand-alone analyzer or can be tied in to plant-wide automation systems to provide real-time strategic measurements.
  • Page 13 Chapter 1: Introduction, Page 6 Features and Benefits • Ideal for analysis of crude and other highly viscous hydrocarbons, pipelines, terminals, blending • Sample stream temperatures up to 464° F / 240° C (with high temperature option) • Proprietary window in flowcell can withstand pressures In excess of 500 psig / 35 bar •...

  • Page 14: Xrt/Xra Analyzer

    Chapter 1: Introduction, Page 7 1.4.1 XRT/XRA Analyzer    DETECTOR X-RAY TUBE HEAD FLOW CELL The XRT/XRA Analyzer components consist of the Flow Cell, X-ray Tube Head, Detector Head, and related electronics. The signal from the Detector Head is fed to the Controller where it is corrected for density and applied in the calibration equation to yield the correct result.

  • Page 15: Controller

    Chapter 1: Introduction, Page 8 1.4.2 Controller The Controller components consist of the PLC and Touch Screen Display. The Controller performs three major functions: The first function is to monitor for error conditions. These conditions can include low purge pressure, piping leaks inside the sampler enclosure, communication failures, density errors, and temperatures outside the set limits.

  • Page 16: Densitometer (Optional)

    Chapter 1: Introduction, Page 9 1.4.3 Densitometer (Optional) The Densitometer components consist of the in-line density meter and processor that calculates the liquid density and feeds that signal to the Controller. The liquid density meter uses the spring mass principle for measuring fluid density. A portion of the measurement tube is energized to vibrate at its natural resonant frequency by using an electrical feedback driving system.

  • Page 17: Installation

    Chapter 2: Installation, Page 10 2 INSTALLATION This Section describes requirements for receiving and installing the analyzer. Site requirements consist of selecting the proper location and preparing it for process access, plant services (power, air, etc.), and suitable environmental conditions. Installer must confirm that the installation and process conditions, as well as the specifications in Section 8 are reviewed to determine that the installation is appropriate with the classified hazardous area.

  • Page 18: Utility Requirements

    Chapter 2: Installation, Page 11 Utility Requirements 2.3.1 Gas Supply Specifications Purge air (or protective gas) is connected to a 3/8” NPT entry at the purge controller. Refer to the Customer Drawings Except for cylinder-supplied gases, the point at which the protective gas enters the supply duct(s) should be situated in a non-hazardous area.

  • Page 19: Electrical

    Chapter 2: Installation, Page 12 2.3.2 Electrical The incoming AC utilized for all analyzers should be “clean” AC, that is, AC with no transient voltages on the line. No voltage dropout 10% below nominal and no voltage spikes 10% above nominal VAC.

  • Page 20: Signal Connections

    Chapter 2: Installation, Page 13 2.3.3 Signal Connections Instrument signals can be connected through 3/4” conduit hubs. Refer to the Custoemr Drawings and Wiring Diagrams supplied with your analyzer for connection details. Signal cables need to be connected to the analyzer through cable glands or conduit hubs. The cables and fittings must be rated for the environment for which the analyzer is intended.

  • Page 21: Process Connections

    Chapter 2: Installation, Page 14 2.3.4 Process Connections The process is connected through 600# ANSI RF flanges (other sizes available by request) at the top and bottom of the analyzer. The process flow inlet should be at the bottom of the analyzer with the outlet at the top. This prevents entrapment of any bubbles in the sample cell of the analyzer.

  • Page 22: Purge Startup Procedure

    Chapter 2: Installation, Page 15 Purge Startup Procedure The AMETEK ASOMA Model 682T-HP, ATEX Zone 2 configuration uses an Expo Model 07/ZLC/bp/IS purge unit to achieve enclosure protection. While this system does not automatically control power to the analyzer (as with an X-purge system), it will trigger an alarm and alert the user upon loss of protective pressure.

  • Page 23: Operation

    The Touch Panel Display will load the Main Screen after about 50 seconds. The 682T-HP is shipped from the factory with an example calibration installed in CalSet0 so you can test analyzer operations immediately. There is no guarantee that this calibration will provide the best results for your application.

  • Page 24: Run Conditions

    Chapter 3: Operation, Page 17 3.1.1 Run Conditions Note that a special power failure recovery feature of the system will cause the analyzer to start in the same state as when power was turned off. The following conditions determine whether the analyzer will start to RUN or be stopped when power is turned on: The system will RUN (start repeat analysis) if one of the following is true (assume power is on and no alarms are active):...

    Chapter 4: Calibration, Page 34 If the pipe arrangement s not the same as pictured, remember to also drain the density meter. The system will warn that the density is low and X-rays will be turned off. This is desirable since the X-rays would temporarily saturate the detector if they were transmitted through the empty flow cell.

  • Page 48: Exponent Method

    Chapter 4: Calibration, Page 41 You have a choice of methods for density correction – Exponent or Alpha or Hyperbolic. Each method can produce equally good fits, but each has advantages and disadvantages. 4.5.1 Exponent method The Exponent method can be used with at least 3 samples and does not need density variation in the samples to produce a good fit.

  • Page 49: Alpha Method

    Chapter 4: Calibration, Page 42 DENSITY is in gm/cc The CPS variable is divided by 100 to increase the number of significant digits that are displayed for the slope in the Calibration Coefficient Screen. 4.5.2 Alpha method The Alpha method requires at least 4 samples with varying densities. There is no need to hunt for the best Alpha coefficient because the calculation is done with the best Alpha automatically.

  • Page 50: Hyperbolic Method

    Chapter 4: Calibration, Page 43 The equation for a calibration fit with Alpha density correction is given as: % S = SLOPE*(CPS/100)*(1+ALPHA*DENSITY)+OFFSET CPS = Counts Per Second DENSITY is in gm/cc The CPS variable is divided by 100 to increase the number of significant digits that are displayed in the Calibration Coefficient Screen.

    Thus at best, it can be expected that 68% of the measurements of a peak will come within this calculated one-sigma deviation from a mean value. AMETEK ASOMA instrumentation can perform to this theoretical best precision limit for many applications. For most applications, however, some error due to instrument precision and sample presentation is added to the error due to the counting statistics.

    If failure or damage occurs which could affect the shielding of the X-ray tube, the appropriate authorities (listed at the end of this section) and AMETEK Process Instruments should be notified immediately. If the instrument is seriously damaged such that the X-ray Head is no longer shielded, the instrument should be turned off until trained personnel can take corrective action.
