A rookie reviewing design calc's for a vacuum tower? What you need is a mentor! But going through someone elses design is probably the best way for you to get exposed. What you need in your cubicle will depend a bit more on what your role in the organization is (filling out your profile would help!).
I used to work at an E&C firm in the PV group and now work at an oil refinery. Along with three other engineers, I work on the maintenance side of static equipment issues. What I keep on my bulletin board includes (in no particular order): A page out of the process design spec for our plant which lists the process and mechanical design pressures and temperatures of our steam and water systems; A table (multiple pages from my former employer's piping design guide) listing pipe thicknesses, inside diameter, weight per foot, moment of inertia, section modulus, etc.; A table (single page) listing pipe thicknesses; A table (from TEMA) listing the modulus of elasticity, thermal expansion coefficients, and conductivity for various metals; a G&W Taylor Forge sheet with dimensions of welding fittings; A risk matrix (risk = probability x consequence) which helps categorize issues for prioritizing repair work; a paragliding (well, and hang gliding also) calender; and various other crud.
What I keep within arm's reach includes (again in no particular order): B31.3; VIII-1; VIII-2 (out of habit, not need); Misc. other ASME codes (three editions of B16.5, B16.9, B16.34, B16.10, B16.47, B30.20); II-D (and parts of II-A); API-579; NBIC; AISC Manual of Steel Construction, ASD, 9th ed.; Roark's Formulas for Stress and Strain by Young; and various other crud.
Lots of other material that I've gathered over the years resides a bit farther away.
