Design Philosophy for H2S Stripper Equipment No. 511 C 001 Rev. 0 1. Design code – ASME Section VIII Div. 1, 2007 Edition. Local load analysis carried out as per WRC 107 for nozzles on dished ends and as per WRC297 for the nozzles on the cylindrical shell. 2. PV Elite Software Version 2008 used for the calculations. Other calculations not covered in PV Elite carried out using Excel as per Good engineering Practice. 3. Nozzle local load analysis carried out for all process nozzles. The loads applied as per ‘Piping Loads Document No. 6922-7-12-0038 Rev. 1. The allowable stresses are found within the limit i.e. 3Sm limit. Sm value taken as allowable stress value from ASME Section VIII Div. 1 ( 1202.27kg/cm2). For nozzle loads without pressure and loads 50% of the table loads, the allowable condition of 1.5 times of allowable is also satisfied.

Assumptions / Notes: 1) Steam out condition for the equipment is 0.5kg/cm2g at 170oC. The design condtion for internal press covers the steam out condition, hence, no separate calculations are required for steam out condition. And the design is safe. 2) Response Spectra method in PV Elite selected (Note: if we use IS1893 RSM method in PV Elite with site spectra gives eratic results). The response spectra values used are further multiplied by Importance Factor =2, divided by Response Reduction Factor =3 & in case of MCE values doubled as required. Hence, in the PVE analysis other factors used as unity. For the calculated values, Refer Annexure A to this Design Data. 3) As fire proofing inside cannot be modeled in PVE, we have modeled the same using internal lining

Note : The value of Ah calculated as above for DBE are lower than corresponding values that for MCE, hence, PVE analysis is carried out with MCE values. Also, the allowable can be increased for MCE as per 6812-00-16-46-DB-01 Rev. 0, however, we have not increased these but without the allowable increase the design is safe.

Note : The value of Ah calculated as above is used in PVE Response Spectra Analysis with other factors as unity

The Natural Frequencies for the vessel have been computed iteratively by solving a system of matrices. These matrices describe the mass and the stiffness of the vessel. This is the generalized eigenvalue/ eigenvector problem and is referenced in some mathematical texts.

Wind Load Calculations per India Standard IS-875

The Natural Frequency for the Vessel (Empty.) is 0.82838 Hz. The Natural Frequency for the Vessel (Ope...) is 0.76578 Hz. The Natural Frequency for the Vessel (Filled) is 0.60576 Hz. PV Elite 2008 ©1993-2008 by COADE Engineering Software

The computation of the Gust Response factor G is not required because the height to diameter ratio is less than 5 and the natural frequency is greater than 1.0 hertz, or the user may have opted not to use the Gust Factor at all.
