Safety Relief Valve Venting

[wlc1]

I am looking for a design guide for venting two safety relief valves into one common vent pipe. If you know where to look please let me know.

See if API 520 Part II helps. The title is Sizing, Selection, and Installation of Pressure-Relieving Devices in
Refineries

Part II—Installation

I think that the current edition is API RECOMMENDED PRACTICE 520 FIFTH EDITION, AUGUST 2003.

WLC1,

You may also want to look at API RP-521, GUIDE FOR PRESSURE-RELIEVING AND DEPRESSURING SYSTEM. Refer to their sections 4 and 5 covering disposal systems (atmospheric, flare, etc.)

Another good all-around reference for relief systems is "Guidelines for Pressure Relief and Effluent Handling Systems" which is an AICHE, CCPS publication.
