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.
Working principles
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.
