Wax appearance temperature (WAT) analyzer for crude

Also known as cloud point, wax appearance temperature is the temperature at which a crude oil sample first precipitates solid wax as it is being cooled under prescribed test conditions.
Similarly, Wax Disappearance Temperature (WDT) is the temperature at which the last wax solids are melted into liquid during a warming cycle.
Until now, trying to determine crude oil WAT or cloud point was an imprecise, tedious, and subjective process. Various manual methods have been tried, but all are difficult and time-consuming, yielding results with unacceptably wide error margins.
Phase Technology’s new WAT-70Xi analyzer revolutionizes the upstream and midstream oil industries with the world’s first and only totally automatic process to measure WAT and WDT of crudes. Based upon ASTM D5773, our proprietary optical light scattering technique detects phase changes with extreme sensitivity and accuracy.
This important scientific break-through means that even the darkest, most opaque samples can now be easily tested, with 1.0° C precision. The Phase Technology WAT-70Xi offers a considerable efficiency advantage—just load the sample, and the analyzer does the rest, with tests completed in just 20-40 minutes. There’s no time-consuming manual set-up needed, and cleaning is done automatically after each test.

BENEFITS:
Detection of both WAT and WDT – Two critical tests for understanding crude oil behavior; also determines rate of wax deposition & melting
Super fast speed!  – Test results in just 20-40 minutes, compared to average test times of several hours for other methods.
Tests opaque samples – Enhanced optical configuration “sees” through dark samples Eliminates chance of cross contamination and other human errors
Self cleaning – Automatic solvent flush after each test run
No manual set-up – Simply inject sample directly into analyzer and begin test run
Superior precision – Repeatability of 1.0° C
Greater sensitivity – Controlled, automatic test method ensures no subjectivity in reported results.
