CONSTRUCTION OF A MODEL SHELL AND TUBE HEAT EXCHANGER

 

ABSTRACT

The precise content of this project was to construct a model shell and tube heat  exchanger. The material for construction of this project (equipment) and their dimensions are as follows:

  1. 500mm length of a tube bundle
  2. 20mm diameter of the tube bundle
  3. 650mm length of the shell
  4. 120mm diameter of the shell
  5. 70mm length of the inlet and outlet
  6. 20.5mm diameter of the inlet and outlet
  7. 160mm diameter of the flanges
  8. 8mm diameter of the holes on the flanges.

The construction of this equipment involves a series of processes which includes:

i.             Marking out which was done using metre  rule, pair of compasses, scribers and punch.

ii.            Cutting of the marked materials to shape

iii.          Folding to shape where necessary

iv.          Rolling and boring holes as appropriate

v.           Welding together by electric welding

vi.          Filling for good finish

vii.        Assembling together of the individual component.

The carefulness with which the marking out, welding and final assemble of the work was done made it possible for us to obtain an equipment suitable for use as a model shell and tube heat exchanger.

It is established that a horizontal heat exchanger with cold water at the shell side and the treated steam at the tube side is adequate for this operation, with the aim of cooling the steam from the distillation column.

The introduction of vapour (or any hot fluid) and removal of condensate (or a cooler fluid) is near perfection (100%) while the equipment being a heat exchanger is used to recover vapourised liquid in its former form (liquid) or removed heat from a very hot processed fluid. Significantly, this equipment is of great need when vapourised liquid must be recovered back as liquid at specified conditions.
