American Petroleum Institute Recommended Practice

American Petroleum Institute Recommended Practice. In 1990, the American Petroleum Institute issued a recommended practice on Management of Process Ha2ards (35). The stated objective was to help prevent the occurrence of, or minimi2e the consequences of, catastrophic releases of toxic, flammable, or explosive materials. 

The ASME code requires every pressure vessel that can be blocked in to have a relief valve to alleviate pressure build up due to thermal expan sion of trapped gases or liquids. In addition, the American Petroleum Institute Recommended Practice (API RP) 14C, Analysis, Design, Installation and Testing of Basic Surface Safety Systems on Offshore Production Platforms, recommends that relief valves be installed at vari ous locations in the production system and API RP 520, Design and Installation of Pressure Relieving Systems in Refineries, recommends various conditions for sizing relief valves. 

This analysis forms the basis of a widely used industry consensus standard, American Petroleum Institute, Recommended Practice 14C, Analysis, Design, Installation, and Testing of Basic Surface Systems for Ofi- i orc Production Platforms (RP14C), which contains a procedure tor dcicnniniiig required process safety devices and shutdowns. The procedures ilescribed here can be used to develop checklists for devices not covered by RP14C or to modify the consensus checklists presented in RP14C in areas of the world where RPI4C is not mandated. 

While RP14C provides guidance on the need for process safety devices, it is desirable to perform a complete hazards analysis of tlie facility to identify hazards that are not necessarily detected or contained by process sLifety devices and that could lead to loss of containment of hydrocarbons or otherwise lead to fire, explosion, pollution, or injury to personnel. The industry consensus standard, American Petroleum Institute Recommended Practice 14J, Design and Hazards Analysis for Offshore Facilities (RP14J), provides guidance as to the use of various hazards analysis techniques. 

A separate table such as the example in Table 15-2 is prepared for each line designation. Each valve is assigned a designation on the flowsheets and explained in this table. The pipe, valves, and fittings table can sp( acceptable valves by manufacturer and model number, by a generic description, or by a combination of the two as shown in the example. It should be pointed out that Tables 15-1 and 15-2 are examples from American Petroleum Institute Recommended Practice (API RP) 14E and are illustrative only. There are almost as many different formats for pipe, valve, and fip "" tables as there are companies, and these examples are in no manner ty or recommended. Often, for. simphcity, valve types are not described i pipe, valve, and fittings specifications but on separate sheets for each. ...
