% Interoffice Communication to A. F. Gallagher From 0. H. McCulley oat* November 12, 1974 subject VCM Emissions from Corkin Compressors Following our recent discussion on the Aberdeen Plant's Corkin compressor emission problem, a test run of the VCM Plant's Corkin compressor was arranged- The following VCM concentrations were measured around the com pressor. PPM VCM (Century/Chromatograph) Startup After 30 Minutes Operation Piston Rod Stuffing Box Exhaust ^Cylinder Head Gasket 400-500/NS 37/NS Nil/1.8 Nil/NS NS Not sampled Apparently emissions from our compressor are a problem only when the com pressor is cold* After heating up, clearances must change enough to prevent further VCM emissions. /I/. .
