SAMPLING SYSTEMS
Precision Sample Conditioning & Analytical Delivery System
In high-pressure petrochemical and aviation fuel environments, the leap from a process pipeline to a sensitive electronic analyzer is a major technical hurdle. Raw process stream, whether wet gas, hydrogen, or liquid hydrocarbons, are often too volatile for direct analysis. They contain free liquids, fine mists, and particulate matter that can “slug” an analyzer, causing permanent sensor damage and costly facility downtime. Furthermore, “lag time” in the sampling line can lead to data that is minutes or even hours old, meaning operators are making critical safety decisions based on outdated information. Without proper conditioning, the Joule-Thomson (JT) effect during depressurization can cause condensation, essentially ruining the sample before it ever reaches the sensor.
The Series 7000 Conditioning System is a self-contained, high-performance bridge between the process take-off and your analytical instrumentation. Rather than a simple filter, the Series 7000 is a multi-stage conditioning environment designed to deliver a stable, representative, and “analyzer-ready” sample in real-time.
By utilizing a two-stage kinetic separation process, the system aggressively removes bulk free liquids. This is followed by a secondary fine-mist elimination stage using a proprietary membrane filter with “liquid block” technology. This ensures that even if a process upset occurs, the analyzer remains protected from moisture carryover. To solve the problem of lag time, the system features a High-Velocity Fast Loop, ensuring the fluid being analyzed is a true reflection of the current pipeline state.
- Active Thermal Management: Features a high-precision, heated pressure regulator to mitigate JT-effect condensation. This maintains the sample in a stable gas state regardless of the pressure drop.
- Explosion-Proof Engineering: Designed for the rigors of the oil field, the system includes Ex d self-limiting heating and an Ex e isolating switch, housed in an IP-rated GRP enclosure with an anti-static coating for Zone 1 and 2 hazardous areas.
- Corrosion-Resistant Metallurgy: To handle “sour” gas and aggressive chemicals, all wetted components are fabricated from 316L Stainless Steel, with optional upgrades to Inconel or Hastelloy.
- Precision Pressure Control: Utilizing a large-diaphragm regulator, the system provides fine-tuned outlet pressure (0–10 Bar) even when inlet pressures reach as high as 256 Bar.
