9.7 Process refractometer PR-23-RP
K-Patents Process Refractometer PR-23-RP is a heavy-duty refinery model that is de-
signed to support the unique requirements of the refining 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 PR-23-RP comes with user-specified supplementary tests and documents. The
following items can be specified and ordered: metallurgical and material hardness
certification (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 certification
and the positive material identification (PMI) test. A factory acceptance test (FAT),
site acceptance test (SAT), and customized drawings stating client specific informa-
tion are also available on request.
