Chemical Engineering Days!

Was just going through some old stuff and came across few documents from the time when I was working in the chemical industry. The data collection sheet here was for my department's (TECHNICAL SERVICES) study titled: MEG Plant Debottlenecking Study. After a production job (working in shifts and all!), the Technical Services job was much better because:
a) It was a desk job during normal job hours (no shifts!)
b) I actually utilized my chemical engineering knowledge in this job!

It all makes me feel so nostalgic! Where are those days of Ludwig, Perry's, Nainital, Kashipur :(
