ECP – Emissions Control Panels
Capture your fugitive emissions (to safeguard operator and environment)
Reciprocating compressors are critical for the performance and operation of the entire plant; however, they have been identified as a major source of fugitive emissions which not only negatively impact the environment but can also pose a significant safety risk to operators working on the compressor deck. Nitrogen purging is an effective way to eliminate uncontrolled gas leaks from a compressor, and thus ensure safety on the compressor deck for people and protects the environment at the same time. When HOERBIGER Emissions Control Panels are coupled with a flaring or recovery system you can drastically reduce your greenhouse gas emissions. Purge pressure regulation also minimizes nitrogen consumption and thus lowers the total cost of ownership. Thanks to standardization of our Emissions Control Panels product range and a clever modular design, you just need to pick the model that suits you best. There’s no need for lengthy technical studies in advance.
The purpose of the pressure packing is to keep the high pressure gas in the crank end compression chamber. To prevent emissions of hazardous gases at the compressor, the main packing needs to be purged. A pressurized nitrogen buffer at the flange end of the packing creates a barrier seal between the packing and the distance piece.
The Emissions Control Panel monitors the health status of the main and intermediate packings over time. This allows you to switch from preventive maintenance to condition-based maintenance. To ensure optimal performance and safety over its entire service life, HOERBIGER has selected premium materials and components from Swagelok® to create a durable Emissions Control Panel system that meets the highest quality standards in the industry. Operating autonomously with no electrical components, the Emissions Control Panel is ATEX registered for use in explosive atmosphere (Zone 2 areas) and API 618 compliant.
Your benefits at a glance
| Feature | Advantage | Benefit |
|---|---|---|
The nitrogen barrier routes all packing leakage to the vent line | Safety from uncontrolled gas leaks | No risk to personnel on the compressor deck |
| Controlled fugitive emissions | Environmental protection and achievement of the emission targets | |
| Purge pressure control minimizes nitrogen consumption | Reduced nitrogen consumption | Lower total cost of ownership |
| Two pressure relief valves protect both the packing and the distance piece, even in case of failure | Protection from overpressure | Avoid equipment damage due to failure or wrong regulation |
| Individual packing monitoring | Single-packing regulation allows monitoring the health status of every packing | Allows higher availability and enables condition-based maintenance |
| Digitalization and remote monitoring | All panels have provisions to install a variety of digital instruments | Flexible solution that can be extended in the future |
| The closed version is NACE compliant | The panel can operate with sour gases with no risk of stress corrosion cracking | Higher reliability without costing a fortune |
| Standardization allows to be flexible without being cheap on components | Top-quality Swagelok® components are used on all products classes | High quality of components |
Selection guide
The perfect option for all your needs: The HOERBIGER Emissions Control Panel is available in three variants and different versions.
ECPc – Emissions Control Panel Constant Pressure
These products are the most affordable solution, which guarantees compressor safety and basic monitoring functions at the lowest possible price point, without compromising on the quality of the components or on the safety features of the panel.
ECPv – Emissions Control Panel Variable Pressure
These products provide all features of the ECPc portfolio, with the additional advantage of dynamically regulating the nitrogen pressure to the main packings, always at 1 bar or 15 psi above the flare backpressure. This ensures minimization of nitrogen consumption, as well as improved capability to monitor the compressor health status.
ECPi – Emissions Control Panel Individual Packing Regulation
These products provide advanced functionality. Nitrogen pressure is regulated individually on each cylinder, allowing the operator to monitor the health status of every single packing. If only one packing in the compressor fails, the ECPi will show you which one, thus avoiding time-consuming inspections and minimizing compressor downtime for intervention.
Thanks to the provision for digital instruments, we know we can integrate the panel with the plant’s Distributed Control System whenever we are ready, so that we don’t interfere with our plant outage schedule.
