Standard Compliant Online Vapor Pressure Testing
ERAVAP ONLINE fully complies with latest vapor pressure standards such as ASTM D6377 for the measurement of crude oil, ASTM D6378 for the measurement of gasoline and ASTM D6897 for the measurement of LPG. All three standards are based on the Mini-Method measurement principle where a piston, containing a pressure sensor, is used to expand the headspace above the liquid. Heating the sample to the measurement temperature at a specified vapor to liquid ratio gives you the vapor pressure of the liquid.
ASTM D6378 offers the advantage over the commonly used ASTM D5191 method, that no sample preparation at all is needed. This fact makes the online vapor pressure testing of gasoline easier and therefore more reliable.
The very same methods are used in our laboratory vapor pressure testers. Therefore no correlation between the online vapor pressure tester and the lab-instrument needs to be established. Both are giving the same results.
Durability for 24/7 Operation
eralytics’ R&D team used all know-how and experience gained in seven years of enhancing our laboratory vapor pressure tester during designing ERAVAP ONLINE.
Self-lubricating gears, continuous oil-level monitoring, ruggedized solenoid valves and many more innovations led to an online vapor pressure tester built to last.
This quality-centric design helps to extend service intervals to 6 months or even longer while efficiently avoiding any out-of-control situations.
Minimizing Downtime
Every ERAVAP ONLINE analyzer is delivered with two measurement cells. While one cell is maintained and recalibrated at a safe location the second one is operated inside the explosion proof housing of the analyzer. Swapping them doesn’t require any tools and can be done in less than 5 minutes. Inlet and outlet tubings use quick connectors and only one cable needs to be unplugged.
Measurement cells are interchangeable between different ERAVAP ONLINE units as all relevant operating parameters are stored directly on the measurement cell itself.
Up to Four Fluid Streams
ERAVAP ONLINE handles up to four fluid streams. The configuration of the streams can be fitted to individual needs to include quality control streams as well as cleaning streams for crude oil applications. That way ERAVAP ONLINE can be configured to measure the two inlet and the outlet stream of blending applications and still run QC samples now and then.
The ERAVAP ONLINE analyzer is equipped with 1/8″ compression fittings for the connection of sample and quality control streams and a 1/2″ compression fitting for the slop line. Using eralytics’ sample conditioning system a 1/2″ fast loop is used. Diameters can be adapted to your needs.
Integrating ERAVAP ONLINE into your Control System
Integration of the online vapor pressure tester into your process control system can be done in more than one way. MODBUS communication is available using the Ethernet connection or the RS232 / RS485 interface. Additionally four analog outputs (4-20 mA) can be configured freely to output results. Four digital outputs (24 V, max. 500 mA) can be used to communicate alarms, warnings or states to the process control system. Last but not least four digital inputs can be used to start or abort measurements.
Explosion Protection
eralytics’ online vapor pressure tester is available in two explosion-proof versions using Pepperl & Fuchs purge-controllers:
- ATEX & IECEx Zone 1
- UL Class 1, Division 1
Both versions use nitrogen as the purge gas compensating leakages, maintaining overpressure inside the analyzer.
15″ Touchscreen for Easiest Setup
ERAVAP ONLINE is equipped with an explosion proof 15″ touchscreen. For the initial setup of the communication protocols, the sample streams and the measurement cycle configuration the big touchscreen is used.
During standard operation the predefined measurement schedule is used and data sent over the defined channels. Service personal, however, can use the touchscreen to fully control the analyzer, initiate QC measurements or rinsing cycles if needed. They can also check all relevant system parameters on it.
