9.7 Process refractometer PR-23-RP
K-Patents Process Refractometer PR-23-RP is a heavy-duty reinery model that is de-
signed to support the unique requirements of the reining and petroleum industries.
Typical applications are in accurate liquid concentration mesurements, e.g. acid in
alkylation, glycol or amines in gas processing and multi-product (crude oil, fuel oil,
diesel) interfaces in transfer operations. The main physical properties have been de-
signed in accordance with ASME VIII Div1 and Div2.
The PR-23-RP comes with user-speciied supplementary tests and documents. The
following items can be speciied and ordered: metallurgical and material hardness
certiication (e.g. compliance with the NACE MR0103 or NACE MR0175/ ISO 15156
standard), API recommended tests and welding documents (e.g. WPS, PQR, WQR,
NDE, radiographic test and hydrostatic shell test), material traceability certiication
and the positive material identiication (PMI) test. A factory acceptance test (FAT),
site acceptance test (SAT), and customized drawings stating client speciic informa-
tion are also available on request.
