Water Quality Tester

Solids in Water Determination according to NACE TM-01-73 and API PR 45

Corrosion engineers in the oil and gas producing industry are often charged with the responsibility of evaluating and controlling the quality of injection waters. Furthermore, pro- duction engineers are confronted with formation clogging by solids in produced water.

This instrument is suitable to determine the water quality of produced and subsurface injection water by use of membrane filters according to NACE TM-01-73 and API PR 45. According to this method, the sample is pressed through the filter at constant pressure until a certain volume has passed the filter (procedure A) or for a set time (procedure B).

The apparatus consists of a sample reservoir (10 ltrs max) with two connectors: the pressurized gas inlet and the sample outlet. The sample outlet is connected to the filter holder, which is installed above a container on a digital balance.

After adjusting the test pressure, the automated test is started by clicking START on the PC screen. The valve opens and the gas flows into the sample vessel at controlled pressure. The sample is pressed through the filter and into the second container on the balance. The accumulated weight is read out continuously. When measuring according to procedure A, the valve closes automatically when the set weight is reached.

The instrument is available as stand-alone version or to be connected to a PC/laptop (just one USB port required).
