Description
The Hygrovision-BL dew point analyzer, developed by SPA Vympel, is a high-precision instrument designed for measuring water and hydrocarbon dew points in natural gas applications. This portable condensation hygrometer combines the best features of the CONG-Prima-2M automatic analyzer and the Hygrovision-Mini visual hygrometer, making it the only device to integrate automatic through-flow and manual visual analysis in one unit.
Key Features:
-
Dual-Mode Operation: Supports both automatic and manual measurement modes for water and hydrocarbon dew points, serving as an arbitration instrument.
-
Advanced Optical System: Utilizes a patented optical system with laser-based interferometric analysis for automatic condensation detection and a 40x magnification microscope with dual lighting for high-resolution manual visualization of condensation on the chilled mirror.
-
Total Refraction Principle: Employs the effect of total refraction at Brewster’s angle to accurately register water and hydrocarbon condensation.
-
Data Storage: Stores measurement results from both automatic and manual modes for up to 5 years, with the last 12 measurements displayed on a touch-sensitive screen.
-
Portable and Autonomous: Equipped with a rechargeable battery providing 6-8 hours of continuous operation, automatically activating during external power loss, making it ideal for field use and emergency situations in oil and gas facilities.
-
Data Transfer: Features an IR port for efficient data retrieval.
-
Explosion-Proof Design: Ensures operational safety in hazardous environments, with a sample gas path that prevents over-pressurization.
-
Compatibility: Fully adaptable with the Model-001 pressure reduction unit for measurements at operating pressures (0.03 to 3.5 MPa), preventing condensate formation during gas cooling.
Applications:
-
Continuous online monitoring of gas humidity in pipelines, such as those used in the Nord Stream consortium.
-
Periodic spot-checking and verification of automatic hygrometers.
-
Process control after maintenance activities like hydrotesting, steam cleaning, or regeneration.
-
Arbitration measurements to ensure compliance with gas quality standards (e.g., GOST 5542-2014).
-
Testing new or upgraded gas preparation systems where visual condensate identification is critical.
Certifications and Recognition:
-
Recommended by COOMET as a reference standard for international comparative measurements, with a dew point temperature transfer accuracy of ±0.05°C.
-
Used for over 7 years in the Nord Stream pipeline, the only domestic measurement tool for both Russian and German operations.
-
Backed by Vympel’s 30+ years of expertise in gas analyzer manufacturing.
The Hygrovision-BL is a compact, reliable solution for professionals needing precise, flexible, and robust dew point analysis in challenging natural gas environments.
