Choose the correct answer

Explanation

Option A is correct because distillation towers typically have diameters of 3 to 6 meters and use bubble caps around 15 cm in size. Option B is accurate as the packing height varies depending on the type of packing used, with Raschig rings requiring about three times the diameter and saddle packing needing five to ten times the diameter. Option C correctly states that the minimum hole diameter in sieve trays corresponds to the tray thickness. However, option D is incorrect; the minimum hole diameter in stainless steel sieve trays is not ten times the plate thickness, making this the wrong statement.
