[Complete Reading] API std 2510: Design and Construction of LPG Installations

API Pub 2510A vs API std 2510 vs NPFA 58

API std 2510- provides minimum requirements for the design and construction of LPG installations 

 

4. Design of LPG vessels 

4.1 Applicable codes

4.2 Design pressure and temperature 

(1) Design pressure

DP shall not be less than the vapor pressure of the stored products. 

Additional pressure = partial pressure of non-condensables + Liquid head 

PSV set pressure와 design pressure 정할 때 liquid head 고려해야 함. 

(2) Min Design temperature 

Ambient T, Solar input, product run down T를 고려해서 정한다. 

Lighter HC인 경우 autorefrigeration T를 고려해야 한다. 

4.3 Design Vacuum

Consider the vacuum effect 

4.4 Material of Construction 

 

5. Sitting Requirements and Spill Containment 

5.1 Siting 

5.1.1 General

Spacing is not intended to provide protection from a major incident. 

Spacing is intended to minimize the potential for small leak ignition. 

5.1.2 Minimum Distance Requirement 

Spacing 정리 필요.엑셀. SHELL 것과 비교 

5.1.3 Siting of Pressurized LPG Tanks and Equipment 

Compressors and pumps taking suction from the LPG tanks should not be located within the spill containment area of any storage facility unless provisions are made protect the storage vessel from the potential fire exposures. 

5.2 Drainage

5.3 Spill Containment 

5.4 Remote impoundment 

5.5 Diking 

 

6. Foundations and Supports for LPG storage vessels and releated piping 

7. Tank Accessories including PSV 

8. Piping Requirement 

9. Loading, Product Transfer and Unloading Facilities 

10. Fire Protection 

11. Refrigerated storage
