    Heat exchangers

    Procedure to Take a Heat Exchangerout of Service :-

    1. The hot fluid must be shut off before thecold fluid.

    2. After the hot fluid has been shut off, thecold fluid can be shut off on both inletand outlet valves.

    3. Both shell and tube side should now bepumped out to slop or drained down.

  • 8/11/2019 Process Operation

    36/171

    4.Both inlet and outlet lines should beblanked off for safety.

    5.the exchanger should be water washedbefore opening to the atmosphere (sour oilservice case)

    Heater Tube Failures

    The design pressure of the tube is not theinlet operating pressure of the heater.

    The design tube temperature is theanticipated or calculated maximum tubeskin temperature (at end-of-runconditions).

  • 8/11/2019 Process Operation

    49/171

    The calculated tube skin temperature is

    mainly a function of the fouling resistanceassumed inside the tube.

    A typical process heater tube diameter is 4to 10 in. Tube thickness is usuallybetween 0.25 and 0.50 in.

    50/171

    Heater tubes are often constructed out ofchrome steel, the chrome content increasesthe heat resistance of the tube.

    For added corrosion and temperatureresistance, the nickel content of tubes andsometimes the Moly (molybdenum) content as

    well are increased.

    If we just block in the leaking process tubesand fuel-gas supply, the flue-gas compositionenters the explosive region. The firebox will

    now explode. The correct way to prevent this sort of firebox

    explosion is to use firebox snuffing steam.

    A typical heater firebox might have a halfdozen purge steam connections.

    Engineering control and housekeeping

    Engineering control involves controllingthe hazard at the source. The competentauthority should ensure that exposure to

    hazardous substances is prevented orcontrolled by prescribing engineeringcontrols and work practices which afford

    maximum protection to workers

    methods

    reduce the source of the hazard, so thatrisks are confined to certain areas whereengineering control measures can be

    applied effectively; adopt adequate work practices and

    working-time arrangements so that

    workers exposure to hazards is effectivelycontrolled; and

    108/171

    minimize the magnitude of exposure, thenumber of workers exposed and theduration of exposure, e.g. carry out noisy

    operations at night or during the weekend,when fewer workers are exposed.

    When none of the above approaches isfeasible, or when the degree of safetyachieved by them is considered

    inadequate, the only solution is to provideexposed persons with suitable personalprotective equipment and protective

    clothing.

  • 8/11/2019 Process Operation

    Technological change

    Technological progress can play animportant role in improving workingconditions and job content, but it can also

    introduce new hazards. The hazards associated with technologies

    (equipment, substances and processes)

    used at the work site must be identifiedand effective measures taken to eliminateor control them

  • 8/11/2019 Process Operation

    112/171

    The introduction of new technology shouldbe accompanied by adequate informationand training. Furthermore, potentially

    dangerous machinery, equipment orsubstances should not be exported withoutadequate safeguards being put in place,

    including information on safe use in thelanguage of the importing country.

    Fahrenheit scale was the first temperature scale togain acceptance. It was proposed in the early 1700sby Fahrenheit (Dutch). The two points of referencechosen for 0 and 100 were the freezing point of a

    concentrated salt solution (at sea level) and theinternal temperature of oxen .This eventually led to theacceptance of 32 and 212 (180 range) as thefreezing and boiling point, respectively of pure water at

    1 atm (14.7 psi or 101.36 kPa) for the Fahrenheitscale. The temperature of the freezing point andboiling point of water changes with pressure.

    Celsius or centigrade scale (C) was proposed in mid1700s by Celsius (Sweden), who proposed thetemperature readings of 0 and 100 (giving a 100 scale) for the freezing and boiling points of pure waterat 1 atm.

    Rankine scale (R) was proposed in the mid 1800s byRankine. It is a temperature scale referenced toabsolute zero that was based on the Fahrenheit scale,

    i.e., a change of 1 F = a change of 1 R. The freezingand boiling point of pure water are 491.6 R and671.6 R, respectively at 1 atm, see Fig. 8.1.

    Kelvin scale (K) named after Lord Kelvin wasproposed in the late 1800s. It is referenced to absolutezero but based on the Celsius scale, i.e., a change of1C = a change of 1 K. The freezing and boiling point

    of pure water are 273.15 K and 373.15 K, respectively,at 1 atm, see Fig. 8.1. The degree symbol can bedropped when using the Kelvin scale.
