Abstract: A system and method for determining the vapor pressure of a process stream includes a hard analyzer configured to measure one or more dependent variables associated with a sample of the process stream, where a dependent variable is also a property of the sample such as vapor pressure; a sensor system comprising one or more sensors configured to capture one or more independent process variables associated with the process stream; an aggregation module for collecting and storing outputs from the hard analyzer and responses from the sensor system; and a modeling module capable of generating a vapor pressure model from the same. The system then applies the model to sensor responses for the process stream to generate vapor pressure values.

Abstract: Systems, methods, and apparatuses are provided for determining properties of process streams, in particular, hydrocarbon processing streams.

The systems, methods, and apparatuses provide features that allow such properties of process streams to be accurately measured even as process conditions and other parameters that affect process operations change. More specifically, an analyzer having a measurement device configured to detect one or more independent variables of a process stream, a model configured to determine one or more analyzer measurements from the one or more independent variables, and a procedure to adjust the model using a corresponding primary measurement is disclosed.

Abstract: A vortex flowmeter may utilize a ring-shaped bluff body as the vortex generator or shedder. The ring shape and size of the vortex ring generator may be optimized to produce linear and stable toroidal vortex outputs that may outperform the conventional shedder bar. In comparison to the conventional vortex shedder bar, the ring may have a slimmer configuration and a higher K-factor, and hence, a higher resolution.

Abstract: The disclosure generally relates to mass flow meters and more particularly relates to systems and methods for determining, among other things, a volumetric flow of a liquid portion of a multiphase fluid flow. In certain embodiments herein, an expected liquid density of a fluid flow at an operating condition may be determined. Such a determination may include receiving a measured density of the fluid flow and comparing the expected liquid density of the fluid flow to the measured density of the fluid flow. Further, a phase status of the fluid flow may be determined based at least in part on the expected liquid density compared to the measured density of the fluid flow.

Abstract: Certain embodiments herein relate to configurations for reducing the flow area for fluids traveling through a Vortex flowmeter. Such configurations may establish a minimum required Reynolds number consistent with optimized performance of the Vortex flowmeter. Various configurations for achieving optimized performance may include inserting one or more segments or a streamlined, torpedo-shaped body into a bore of a meter body of the Vortex flowmeter to block a certain cross-sectional area of the bore. By reducing the cross-sectional area of the bore, the Reynolds number of fluids may be increased to the optimized level. Another configuration may include reducing the diameter of the bore of the meter body. Any of these configurations may be implemented to achieve a desired Reynolds number, and hence, optimized performance. Certain embodiments herein also relate to determining or calculating precise or near precise sizes for segment insertions, torpedo body diameters, and diameters of the meter body.

Plural performance rating items are prepared in advance as rating indexes for the production process. Addition or subtraction of points or another arithmetic operation for rating is performed in accordance with whether or not a currently executed production process satisfies the respective performance rating items, thus calculating a final rating value. The final rating value is displayed in a graph. This enables comprehensive rating of performance of an entire production process and multilateral analysis.
