We had a compressor failure in 2013 and had to carry out an unplanned major inspection to replace compressor. Initial startup with new compressor gave a CPD or 10.4 bar. However Initial startup of same unit with an old compressor in 2010 gave a CPD of 10.7 bar after major inspection when the compressor was steam washed.

Are there any other causes of this CPD performance degradation?
