Area Classification to IP 15 (BP) () (RP )_百度文库

Ventilation shall be assessed by a specialist engineer. Onshore, it is the preferred practice for mud tanks to be located in an open area.

arsa There shall be a Zone 1 area extending 0. In this case codr shall be a Zone 1 hazardous area extending 3 m horizontally and vertically upwards from the ditch and vertically downwards to a solid floor, or for 9 m, whichever is less. The local ventilatin system should be of high reliability. If mechanical means of ventilation are provided they should incorporate alarm facilities to detect loss of ventilation.

For such cases it is reasonable to expect the valve stem will be more prone to leakage than infrequently-used block valves that remain open or closed during normal operation. In this case the ventilation air shall be taken from an area classified as non-hazardous. By joining you are opting in to receive e-mail.

Agreements reached on area classification shall be recorded formally. It is applicable to: Some hydrocarbon will be removed in the shale shaker and associated inlet ditch, and in any vacuum degasser.


C3 Piping Systems This Commentary relates to 5. Isolation of such equipment could cause problems and each case must be considered individually. For open-air process plant BP may specify that the hazard radius be determined by the procedure below, which avoids the need to consider each individual secondary grade source of release.

On high integrity and enhanced integrity pumps, there shall be no operational vents or drains, or other likely release sources for Category A or B fluids direct to atmosphere. Drilling mud normally flows between equipment in an open or loosely covered ditch. Theoretically, the fresh oil-based mud is non-hazardous. It may be less hazardous to allow equipment to run.

Defense manufacturing is all about project manufacturing and project accounting. Amendment to IP 15 Figure 3. Active mud tanks located in the open can be classified in accordance with Figure 3.

For fluids with a significantly higher volatility, the distance D in Table 5. With a correctly designed system with a hood the flow of air will almost certainly be sufficient to avoid classifying the volume within the tank as Zone 1. Ventilation shall therefore be provided for non-sealed types so that hydrogen concentrations are kept below 0.

Deletion of IP 15 5. The procedure in 5. Should more volatile oils be used, then it may be necessary to classify the fresh mud tanks as hazardous. Local extraction ventilation is often fitted to mud tanks in enclosed areas to improve the working environment. Substitution for IP 15 4. If access exists between an external Zone 1 and an overpressure protected non-hazardous area, then an air lock shall be installed to prevent direct connection.


Where there are adjacent non-hazardous Zone 2 and Zone 1 areas, which it is desired to keep separate by this means, then the pressure in the non-hazardous area must be greater than in the Zone 2 area, which must have a greater pressure than the Zone 1 area. In such a case the internal space should be pi15 in accordance with Table 6. Oil-based mud in the active tanks should be regarded as hazardous, with any vents, open hatches or ditches regarded as primary grade claxsification.

Feedback and Further Information Users are invited to feed back any comments and detail experiences in the application of BP RPSEs to assist in the process of their continuous improvement. Shale shakers are also often fitted with local extraction ventilation. On any such pumps there is likely to be some small continuous vapour leak around the seal. The provision of a closed system for process vents, process drains, and level glass drains discharging Classificatiion A fluid.

Fixed roof tanks with a nitrogen blanket and venting to atmosphere shall be classed as a primary grade source of release.
