Temperature, pressure, and flowrate are variable up to 650 C (1200 F), MPa (1000 PSI), and 5ml/minuterespectively.

3 Plus all may be independently adjusted and controlledto allow the simulation of an extensive range of process applications include: fouling Research heat induced particulate formation testing Gas turbine fuel degradation studies heat transfer coefficient determinationsEasy-to-Use Windows InterfaceFor optimum convenience, all operational parameters andcommands are selected and/or entered via a dedicated PC runningLabVIEW for Windows. Once a test is initiated, no furtheroperator interaction is required; the HLPS executes each step of the testing process with digital precision and accuracy and thenreports/stores the results automatically for later review and , Modular DesignThe HLPS features a modular design which can be easily expanded asyour Research needs change.

4 The basic system consists of a base unit,dedicated PC, and reservoir; differential pressure and heating modulescan be added as Module This module is the very heart of the HLPS; it serves as the main test heat Exchanger and is where all actual testingand measurement takes Module This is a dedicated personal computer runningLabVIEW for Windows. It provides the system s user interface and is used for test setup, initiation, and datalogging. A printer is includedwith the Pressure System This is required for simulations in which the differential pressure must be measured, such as in gasturbine fuel thermal degradation studies and heat induced particulateformation testing.

5 It incorporates a fine filter and electronic pressure transducers to determine the P across the filter asparticulate System Simulations involving the use of crude oil or similar high viscosity liquids often require heating to ensure proper flow through the system. This system enables the user tocontrol and monitor sample reservoir, pump, and line heating fromthe base Control System This system provides control of the heatexchanger by metering the available power. This is important inrigorous heat transfer experiments and for studies involving metals for which tubing is not readily available.

7 And while there arevarious methods of studying heat transfer, one of the best is thecareful measurement of U in a real system. The HLPS-400provides an accurate, yet simple means of performing all thenecessary measurements using the actual fluid of interest andexpected operational maximum flexibility, the HLPS-400 can be set to control theheater tube temperature or fluid outlet temperature. The former isused to simulate systems where there is a constant or maximum heatflux, such as in an economizer or other process Exchanger ; the lateris more representative of applications where there is a need fortemperature maintenance, such as in a furnace or reboiler test fluids include crude oil, sour crude oil, reduced crude oil, fuel oil, diesel oil, HDS feed, and FCC feed.

8 Typicalapplications are anti-foulant performance testing, heat transfer fluid performance testing, and lubricant cycle heat Transfer Testing: heat Induced Particulate FormationThe heat induced formation of particulate can create a problem justas real, albeit more subtle, as the decline of the overall heat transfercoefficient, U. Particulate formation may be seen as a rise inpressure, P, across a heat Exchanger as the material deposits andrestricts flow. It may also show up later in the process by providingseed material for the formation of deposits such as sheets or popcorn systems with the differential pressure system permit testingfor this heat induced particulate formation.

9 As fluid passes througha fine filter in this module, any particulate present is deposited,creating a rise in the differential pressure across the filter. The P ismeasured with a precision differential pressure transducer and theresulting value(s) output to the computer control test fluids for this type of investigation include liquidpetroleum gases, light naphthas, gasoline, kerosene, diesel oil, HDS feed, and monomer feedstock. Typical applications are anti-foulant/anti-oxidant performance testing, thermal oxidationstudies, and fuel stability with optional Heated System3234 East Pasadena , TX 77503 Phone:713-590-7260 Fax:713-590-7266 Toll Free:1-800-444-TESTI nternet: icationsSample CapacityOne liter (under system pressure); unlimited at ambient Tube Temperature650 C (1200 F) MPa (1000 PSI) Pressure700 kPa (100 PSI) to ml per (W) x (D) x (H) meter ( x x inches).
