ASTM D6502 Measurement of On-line Integrated Samples of Low Level Suspended Solids and Ionic Solids in Process Water by XRF

ASTM D6502 Measurement of On-line Integrated Samples of Low Level Suspended Solids and Ionic Solids in Process Water by XRF

ASTM D6502 is a standard test method for measurement of on-line integrated samples of low level suspended solids and ionic solids in process water by X-ray fluorescence (XRF). It covers the operation, data interpretation, and calibration of an online corrosion product (metals) monitoring system. The values expressed in SI units should be considered standard.

    Scope:

    Power plant operators are concerned about corrosion products in particulate and dissolved metals in electricity-producing plants’ steam and water circuits. Corrosion products in the feed water also enter the steam-generating components, which deposit on heat transfer surfaces, lowering the plant’s overall efficiency. A time profile of corrosion product transit is established using more frequent readings in the online monitor through ASTM D6502. Operators will make better informed operational decisions on corrosion product generation and transportation as a result.

    Procedure

    In ASTM D6502, the gadget is introduced as indicated by the manufacturer instructions. The test control valve should be in the air, giving wind current through the whole system. The main discourse board permits the test performer to enter test arrangement boundaries or start or quit testing. The framework cycles between test collection and X-beam investigation until the user ends the program. A channel might stay in help until one of two conditions emerges: when the amount of a component on a channel surpasses that of the best quality utilized for alignment, or the development on the channel causes unnecessary stream limitation.

    Apparatus details 

    The online metals analyzer comprises the accompanying primary parts: X-beam test and related hardware, stream cell and channel chamber, stream aggregator, valve exchanging system, and instrument control and information procurement framework.
