Condition Monitoring on a reciprocating compressor in a shale oil plant

Reciprocating compressors are often used to handle very dirty and corrosive gases that have a negative impact on component lifetime and affect on the plant productivity. Due to this fact there are several ways to handle this problem, a few plants are using a identic machine as backup and in case of failure they are using the twin machine to keep the process running. But maybe this is not the best way. Efficient plants are asking for a condition monitoring system, this is where PROGNOST Systems comes to the play. A installation of a condition monitoring system like PROGNOST®-NT brings several benefits to the operator. Starting at the maintenance planning because he sees the development of his wearing parts and [...]

Early Recognition of abnormal Wear Conditions

2020-06-05T09:49:09+02:009. May 2018|Published Articles|

Residual abrasive contaminants in new process units can cause rapid wear of rider bands in reciprocating compressors. Those abnormal wear conditions can be detected at an early stage by continuously monitoring the proximity measures. As a result, costly damages to the compressors can be avoided.

Challenges associated with the application of automatic diagnosis to Rotating Equipment

Effective Vibration Monitoring for Reciprocating Compressors

Modern standards require frame sensors and more This paper reviews and discusses the machinery protection philosophy for reciprocating compressors that once was state of the art, and examines how technology, as well as applicable standards, have evolved since the 1970s, a time when many refineries have been built with a large fleet of reciprocating compressors installed. For decades, reciprocating compressors did not enjoy the high-priority monitoring given to centrifugal machines. The reasons why are partially based on the higher number of centrifugal machines in comparison to reciprocating compressors, and operators just did not fear severe damages due to the lower kinetic energy of these comparably slow-running machines. However, they show the highest number of damages while being process-critical at the [...]

Improving a Compressor Protection Regime

Analysis of the build-up to the fracture of a compressor crosshead led a refiner to revise its approach to performance monitoring. Compressor crosshead fractures are costly, leading to unplanned outage of the system and loss of production. PROGNOST Systems claims that the development of fractures in the motion work, especially on the crosshead, can be detected by using segmented peak-to-peak piston rod position analysis. The company also recommends this as a mandatory parameter and for safety interlock. This claim was proven to be true by a complete fracture of a crosshead which could have been avoided if the automatic interlock had been activated by the operator. The experience of this case also motivated the operator to improve their site shutdown [...]
