Principal Components Analysis for Early Events Detection in Process Operations

13th Topical on Refinery Processing

Principal Components Analysis (PCA) is a statistical technique that aims at reducing the problem dimensionality by progressively eliminating redundancy in data. The method has found extensive use in exploratory data analysis as it aids visualization of complex data. Interestingly, the method is data driven which makes it suitable for mechanical learning.

Rotating equipment such as pumps, compressors and turbines are vital equipment in processing plants. Malfunction(s) in the operation of such equipment can have serious and sometimes disastrous consequences. Operation of rotating equipment therefore demands continuous surveillance. However, the current state of affairs is less than satisfactory and would greatly benefit from an easy to implement Early Events Detection (EED) program.

We recently investigated one such a possibility of using PCA for EED; the results are promising and are discussed in this paper.
