Vessel Design

1. Vessel Design Design of Horizontal & Short Vertical Vessels

2. الأول : هو احنا هناخد إيه النهاردة في السكشن؟ الثاني : هناخد Vessel Design الأول : يوووووووووووووووووه  أمال هناخد Reactorامتى؟ الثاني : قصدك على سكشن ال non-isothermal يعني؟ أنا شفت الاعلانات بتاعة السكشن امبارح على ال MBC 2 وقالك:Coming Soon on December فقط وحصريا على شاشة ال MBC 2 الثالث : أنا مش عارف انتو ازاي فايقين ورايقين كدة وقاعدين تقولوا هناخد إيه ومش هناخد إيه ومش حاسين بالكارثة اللي أنا فيها الاتنين في نفس واحد : كارثة إيه يابني؟!!! الثالث : سؤال بجد مصيري ومحيرني جدا ونفسي ألاقي له إجابة  الأول : ياعم ما تخلص وتقول بقى وقعت قلبي الثالث : يا ترى sheet النهاردة كام مسألة؟!!!!!!!!!!!!!!!!!!!

3. A Real Tall Vertical Vessel Sheet 5: 2 Problems

4. Design of Short Vertical Vessels (L < 6m) Sheet 5: 2 Problems

5. In designing short vessels, we firstly calculate the thickness of shell and heads according to the operating pressure [i.e. internal or external]. In this case we will not do checks on the thickness as done in tall vessels so, we will design the support directly.

6. Lug Support Theuse of lugs is typically limited to vessels of small to mediumdiameter (1 to 10 ft.) andmoderate height-to-diameter ratios in the range of 2:1 to 5:1. And of Course Sheet5: 2 problems

7. Design of Lug support: Sheet5 : 2 Problems • After calculating fs, you should select the dimension of pipe (lug) and check on your selected dimensions [i.e. check if the lug supports will withstand the load applied on it]. Following are the steps used to select the suitable pipe dimensions: • From the following table, assume nominal diameter to get the inside and outside diameter of the pipe. Begin your assumption with nominal diameter = 2" [always take the Schedule number = 80].

8. Sheet 5: 2 Problems

9. Calculate the radius of gyration (r) from the following equation: • Calculate the value of h’/r. • Make the check on the selected pipe dimensions according to the value of h’/r . Those values are summarized in the following table:

10. If the corresponding check is not correct, assume another nominal diameter [greater than 2"] and repeat the above steps.

11. Design of Bearing Plate: • Assume: In order to check on this assumption, use the following formula:

12. Design of Anchor Bolts: If σtension) max = - ve value: the number of bolts equal 4 used for fixation. If σtension) max = + ve value: the number of bolts calculated from the following equation:

13. Design of Horizontal Vessels Hello?! I just want to tell u that sheet5 : 2 problems

14. Design of Horizontal Vessels Design of Saddle Support: or

15. Sheet5: 2 Problems In Mass Transfer?!

16. I’ll go to the section now. I don’t know which subject but they told me that Sheet5: 2 Problems Assume:

17. Sheet5: 2 problems? Yes  Design of Bearing Plate: Assume: • Design of Anchor Bolts: only 4 bolts for fixation

18. Sheet 5

19. A pressurized vessel lined internally with 4 mm Nickel material is to be fabricated and installed out of doors in Mostorod area. The vessel has the following specifications: Shell inside diameter 1.5 m Shell length 4 m Maximum internal pressure 20 atm.gage Operating temperature 150ºC Lug support height 2 m No. of lugs 6 Corrosion allowance 1 / 16 in.

Shell material C.steel Allowable tensile strength of material of construction 15000 psi Head type Dished Specify the design for: - Shell & heads. - Lug support, bearing plate & anchor bolts. - Maximum permissible vacuum applied in the vessel.

20. A process horizontal vessel is to be fabricated and installed out of doors. The vessel has the following specifications: Shell inside diameter 1.1 m Shell length 2.1 m Maximum internal pressure 10 bar Distance between two supports 1.25 m Operating temperature 150ºC Support height 1 m Fluid Heavy hydrocarbon Corrosion allowance 3 mm Insulation thickness 50 mm Shell material Carbon steel Allowable tensile stength of material of construction 1000 kg/cm2 Type of heads Dished Specify the design for: - Shell & heads. - Support, bearing plate and anchor bolts.
