Could you show me the version of Ruby which you use?
It seems to me that it is Win32OLE memory leak bug.
And the bug is fixed in Ruby 1.8.6.

If you use 1.8.6 or later, then try GC.start after excel.Quit()

     excel.ActiveWorkbook.Close(0)    # close the workbook
     excel.Quit()       #  close Excel file
     excel = nil # <-- add 
     GC.start  # <-- add

Or,  try the creation of Excel object out of while loop scope.
You create Excel object only at once, and call excel.quit only
at once.

   excel = WIN32OLE::new('excel.Application')   # create excel only at once
   while i<count
     ...
     workbook = excel.Workbooks.Open("#{path}") # Open the Excel file
     ...
     excel.ActiveWorkbook.Close(0)    # close the workbook
   end
   excel.Quit # excel quit only at once.
