MINIVAP ON-LINE Vapor Pressure Analyzer

		MINIVAP ON-LINE RVP Process Analyzer

Grabner/Reid Vapor Pressure On-Line Analyzer

MINIVAP ON-LINE is a process monitoring analyzer for the determination of the vapor pressure of gasoline, crude oil, LPG and NPG. Also, the vapor-liquid ratio (LVR) of gasoline can be measured. The measuring principle is identical to the worldwide used laboratory instruments MINIVAP and therefore the MINIVAP ON-LINE produces equivalent results.

Up to 2 different sample streams can be connected to one single analyzer. It is the only available process vapor pressure tester that fully complies to the industry relevant ASTM standards for gasoline (ASTM D6378), crude oil (D6377) and LPG (D6897).

The unmatched accuracy makes refineries save thousands of Dollars each day!

Applications
The measuring principle is based on the triple expansion method of Grabner Instruments´ worldwide approved and accepted laboratory vapor pressure tester for gasoline and crude oil: MINIVAP VPS. The US-EPA declared MINIVAP the official reference instrument for the USA in 1993.

With MINIVAP ON-LINE, the vapor pressure of gasoline (D6378 / D5191), crude oil (D6377 / D323), liquid petroleum gas (D1267) and the vapor-liquid ratio temperature of gasoline (D5188) can be determined. With possible connection of up to 3 different sample streams, all of these measurements can be performed with one single instrument.

Principle
The sample flows from the sample conditioning system via a quick connector (3) and sample inlet valve (4) into the measuring chamber. The automatic sample introduction and volume adjustments are made by a piston with an integrated pressure transducer (1). The measuring chamber (2) with a total volume of 5 mL is rinsed with 2.5 mL and filled with 1 mL. After closing the valve (4), the single or triple expansion to 5 mL (with the sample under vacuum condition) is obtained by further strokes of the piston. The temperature of the measuring cell is controlled with a high-power thermoelectric module (5) and measured with a precision Platinum sensor (6). To achieve fast pressure equilibrium, especially for crude oil, the measuring unit is rocked during the test procedure.
