BARTEC Benke Vapor Pressure Process Analyzer RVP-4

Name: BARTEC RVP-4 Vapor Pressure Analyzer – Datasheet & Quote
Brand: BARTEC

Description

Product Overview

The BARTEC RVP-4 vapor pressure analyzer (BARTEC Benke) is an online process analyzer for vapor pressure measurement of petroleum products. It performs automated, cyclic measurement of vapor pressure (VP/VPX) in fuels, crude oil, liquefied gases and viscous samples, providing continuous quality data for process control without manual sampling.

The RVP-4 analyzer uses the expansion method with piston per ASTM D5191 / DIN EN 13016-1, and correlates with other vapor pressure methods including ASTM D323, ASTM D4953, ASTM D5482 and ASTM D6377. It is designed for installation in hazardous areas of refineries and terminals, with analyzer house or Zone 1 certified configurations.

Ordering and Selection

When selecting the BARTEC vapor pressure analyzer, confirm the sample type, pressure class and installation environment, because each BARTEC RVP-4 analyzer is built for a specific product stream. The BARTEC RVP-4 vapor pressure analyzer measures VP/VPX of fuels and crude oil, and the selected vapor pressure analyzer must be matched to the product range and terminal layout at your site. Our team can help you confirm that the BARTEC RVP-4 vapor pressure analyzer you select is correct for your application.

Our engineers help you verify the exact model and revision before ordering, avoiding costly mismatches.

Planning an RVP-4 Installation

An online vapor pressure analyzer gives useful data only when the sample reaching it represents the product in the line. When planning a project, consider:

Sample take-off: use a probe in a well-mixed section of the line, away from dead legs, and keep the transport line short to limit lag time.
Sample conditioning: filtering, pressure control and temperature management are needed to keep light ends in the liquid phase before measurement.
Analyzer housing: choose between an analyzer house and a Zone 1 certified configuration, based on the site’s area classification and access for maintenance.
Sample return: plan a safe route for the sample back to the process or to a recovery system, in line with site environmental rules.

Commissioning and Validation

At commissioning, confirm utilities and sample flow, then validate the measurement against laboratory results from samples taken at the same point. Compare the online value with the laboratory method the plant uses for product certification, and use the correlations to the ASTM methods listed above to agree how the two results relate. Set up the HART, Modbus or analog outputs and check scaling and alarms at the DCS before the value is used for blending or quality control.

Maintenance and Troubleshooting

A routine of preventive maintenance, validation checks and filter changes keeps the analyzer reliable. If results scatter, check for vapour or air in the sample, a blocked filter or unstable sample temperature. If results drift steadily away from the laboratory, check calibration and the condition of the measuring cell. Keeping a record of each validation result helps show when the analyzer needs attention.

Refinery and Terminal Use in Oman and the GCC

Vapor pressure is a key specification for gasoline, crude oil and NGL exports, and it is closely watched at refineries, blending facilities and export terminals across Oman and the GCC. An online BARTEC RVP-4 vapor pressure analyzer supports tighter blending control and faster product release than laboratory-only testing.

About brand

Explosion protection is the common thread in everything BARTEC makes. The company was founded in 1975 and is based in Bad Mergentheim, Germany, and its equipment is built to work safely where flammable gas or dust may be present.

Seven Star LLC lists BARTEC process analyzers, Ex enclosures, switching components and hazardous-area tablets, and supplies them to refineries, gas plants and panel builders in Oman by type number.

BARTEC product families on this page

The analyzer group is the largest. Under the HYGROPHIL name there are the HYGROPHIL F 5674 process trace moisture analyzer and the Hygrophil HCDT hydrocarbon dew-point analyzer. Under the BARTEC BENKE name there are the RVP-4 vapor pressure process analyzer and the P-600 salt in crude analyzer. The electrical side is represented by the GUB flameproof Ex d IIC enclosure and the 07-1511 series insert switch, a component used inside control stations. The Agile X IS is a tablet PC for Zone 1, and the EXguard is a mobile gas detection system for hot work.

Where BARTEC equipment is used

Moisture and hydrocarbon dew-point analyzers monitor natural gas at dehydration units, pipeline entry points and custody stations. Vapor pressure and salt in crude analyzers serve refinery blending and crude treatment. Flameproof enclosures and Ex switches go into local control stations, junction boxes and motor starters. Ex tablets are used for inspection rounds and work permits on GCC oil and gas sites.

Ordering BARTEC parts: what we need

BARTEC identifies products by a type number, such as 07-1511-154D/02 or 5674-xx. Send that number in full with the serial number from the label. For analyzers we also need the gas or liquid composition, pressure and temperature at the sample point, the measuring span, the area classification and the signal outputs. For enclosures give the size, the required gas group and temperature class, and the cable entry schedule.
