New HOERBIGER Aftersales Service:

Compressor Audit highlights Improvement Potential

The HOERBIGER REE audit makes reciprocating compressor operators aware of the present performance level of their equipment and forms the basis for suggestions on how to boost the reliability, efficiency, and environmental compliance of entire compressor fleets. This HOERBIGER Service offering is a new approach for operators of refineries, and oil, gas, and process industry plants.

The principle of the reciprocating compressor has been around for quite some time, and the machines are very durable. Still, usage conditions and the periphery of compressors change at an ever faster pace. With the HOERBIGER REE audit for compressors (REE - Reliability, Efficiency, Environmental Soundness), the company offers an unprecedented unique service for customers, which does not impair the operator's day-to-day business and highlights the actual performance potential of the compressors during operation. Frequently, the compressor's design no longer fits changed production processes, and even small retrofits can lead to enormous energy savings. The HOERBIGER REE audit also points out options and the potential of upgrades and revamps in these situations.

Economical for decades

In the past, reciprocating compressors were designed for a particular capacity; if circumstances change, efficiency goes down. In addition, old piston rings, guides, and packings often no longer meet today's requirements, making compressor operation less economical, burdening the environment with leakage gases, and impairing process reliability. Uncovering such insidious processes requires a fundamental analysis of the compressor and its environment.

The HOERBIGER REE audit focuses on reliability, efficiency, and environmental soundness. Drastically fluctuating production processes and stringent environmental regulations increasingly strain the reciprocating compressor, which is the heart and workhorse of refineries, chemical plants, and natural gas production or storage operations. As a developer and manufacturer of performance-defining components and systems, HOERBIGER has decades of experience in all common compressor brands. This benefits customers in Service by enabling them to bring existing equipment up to the best possible level of technology with a HOERBIGER REE audit – and giving them a transparent overview of the return on investment. The concise HOERBIGER REE audit report comprehensibly illustrates the state of the art and the improvement potential from adjustments to the compressor. In addition to the technology itself, the on-site analysis also takes the customer's plant processes, compressor design, operating conditions, and maintenance practices into consideration.

Fountain of youth for reciprocating compressors

The HOERBIGER REE audit report assesses every compressor on a scale from 0 to 10 points in terms of reliability, efficiency, and environmental compliance. 0 means out of operation, 10 denotes the best-possible known performance in the analyzed categories. This forms the basis for developing various upgrade scenarios, presenting their investment costs compared to the possible savings, and identifying additional potential, such as lower energy consumption or higher reliability and longer maintenance intervals. If the operator follows these recommendations, considerable improvements can be achieved with measures that are sure to produce fast results. Reliability increases drastically when old packings or valves are replaced with modern high-performance products. New intake valves equipped with modern capacity control enable major energy savings in compressors that operate in a flexible process landscape not marked by constant full or half load scenarios.
