Application February 26, 1935, Serial No. 8,262
11 ‘Claims. (C1. 23-288)
This invention relates to heat exchange sys
tems for a circulated ?uid medium and to mani
folds therefor. More‘ particularly, it concerns
heat exchange systems for converters for effect
5 ing chemical reactions, both exothermic and en
dothermic, especially when the reactions occur
with or in the presence of catalytic or other con
tact masses.
[
One object of the invention is to devise com
10 pact and e?i'cient apparatus for a heat exchange
system which provides for relative movement of
parts and reverse movement of ?uid.
Another
object is suitably to mount the heat exchange
apparatus within a converter. Another object is
to provide a novel supporting arrangement for
1
?uid conduits which latter extend from a manifold
into a reaction chamber. Still another object is
to design a manifold capable of use as a unit. in
the assembly of large converters. Still other
20 objects will be apparent from the detailed de
scription which follows.
In order to illustrate the invention, one con
crete embodiment with minor modi?cations is
shown in the accompanying drawings, in which:
Fig. 1 is a vertical sectional view through a
converter substantially on the line l--I of Fig. 2,
showing some of the parts in elevation;
Fig. 2 is a transverse sectional view on an en
larged scale substantially on the line 2—2 of
30 Fig. 1, showing the manifold unit in plan with
certain details in section; .
Fig. 3 is a vertical sectional view of the upper
portion of the converter substantially on the
line 3-3 of Fig. 2, showing additional details of
35 the heat exchange system and a modified form
of the upper tube sheet; and
Fig. 4 is a detail sectional view on a greatly en
larged scale substantially on the line 4-—4 of
Fig. 3.
40
The converter comprises a casing 5 having a
detachable cover 5a and the entire exterior lagged
with heat insulating material 5b‘. Within are
suitably supported perforated partitions or ?ue or
tube sheets 6 and ‘l dividing the interior into
45 an upper manifolding chamber A, an intermediate
or central reaction chamber B, and a lower mani
folding chamber C. Reaction chamber B is sub
stantially ?lled with a catalytic or other contact
mass M capable of effecting, promoting or assist
5 O ing in the desired reaction. The reactant ?uids
may be sent into the converter from either end,
and the reaction products removed from the op»
posite end.
5
A heat exchange system is provided for con
trolling the reaction by imparting heat to or re
moving heat from contact mass M as may be .de
sired or required. The system sends the heat
exchange ?uid, preferably in the form of a liquid
such aswater, mercury, diphenyl, or the like and
under pressure, in andthrough the mass in a 5.
plurality of parallel streams and in a reverse
?ow arrangement; i. e. one stream ?owing in the
reverse direction to another adjacent or surround
ing stream thereof. To this end, a series of
elements D each comprising inner supply tubes 8 10
and outer tubes 9 in nested telescoped relation
extend. through perforations in upper partition
6 into contact with mass M to substantially the full
depth thereof. By preference, outer tubes 9 are
kept- out of directcontact [with mass M by an
enclosing member Ill which may be either per
forate or imperforate, as will be later explained.
In a uniformarrangement of heat exchange ele
ments D in a converter such as 5, there will be
a number of such elements in line and a series
of such lines. The elements in each line are pref
erably connected to the same manifold E as indi
cated- in Fig. 3,.and a plurality of such aligned
series of elements and manifolds therefor are
indicated in Figs. 1 and 2. Each manifold E
comprises an inner supply conduit H which has
connections to each of the inner tubes 8 of .ele
'
15
20
25
ments D in a given series and an outer conduit
l2 in spacedenclosing telescoping relation with
conduit II and into which outer tubes 9 of ele- 30
ments D discharge. As indicated in Figs. 2 and'3,
inner conduit H of each manifold E projects be
yond the outer conduit l2 and has a bent con
nection [3 leading to a supply main l4 extending
above and transversely to manifolds -E.
A con- 35
nection‘ l5 leads from ‘main M to the converter ,
casing ‘to make a ?uid-tight joint at-l5a with a
supply conduit 15b extending through the con
verter wall. Each of the outer conduits I2 of
manifolds E has a short connection 16 leading as
to outlet main 11 disposed above and transversely
to manifolds E and in parallel with supply main
M. A long looped connection is extends from
main i'l- to make a fluid-tight joint at I8a. with gs
an outlet conduit 1812 which projects through
the converter wall.
,
'
Inasmuch as there will be wide temperature
changes in'the heat‘ exchange system, especially
when it is utilized to control strongly exothermic
or strongly endothermic reactionaadequate pro
vision must be. made for relative movementof
parts; In the case of the nested tubes 8 and .9
making up the elements D which extend into.
reaction chamber B, innertube 8 is “mounted cen
trally ,of outer tube 9,. and there is su?icient ‘5

clearance between these tubes for their own
movement and for variations in the relative
lengths of inner and outer conduits I I and I2,
respectively, of manifolds E. To guide the move
ment of the last named conduits and to prevent
binding or other mutual interference tending
to distort or rupture the same or the nested tubes
8 and 9 makinar up elements D, guide members or
projections I9 (Fig. 3) may be mounted in or
on outer conduits I2 for sliding contact with inner
conduits II. In addition, inner conduits II have
guide members 20 (Figs. 3 and 4) which together
with members I9 effect three-point contacts at
suitably spaced intervals throughout the length
15 of manifolds E.
Elements D may extend within
enclosing members It, with ample clearance, as
clearly indicated in Figs. 1 and 3. To de?ne and
limit the extent of projection of elements D Within
enclosing members I 0 and within reaction cham
ber B outer tubes 9 of elements D have ?xed
stop members 2| thereon which rest loosely upon
a plurality of suitably disposed bearing or sup
porting surfaces, such as the tops of members I9
which latter may, in turn, be joined to supporting
structure such as partition member 6 (shown in
Fig. 3). Stop members 2i may serve as closures
or caps for the latter and be arranged for trans
rations of members III and pass along or over heat
exchange elements D enclosed therein. Inasmuch
as the present invention may be considered in
certain respects as an improvement upon or fur
ther development of the invention disclosed in
the copending application of E. J. Houdry and
R. C. Lassiat, Serial No. 728,544 ?led June 1, 1934,
which issued as Patent No. 2,078,947 on May 4,
1937, it is apparent that there may be mounted
in reaction chamber B one series of perforated
conduits additional to conduits I 0 and even more
than one such series when conduits ID are im
perforate as in Fig. 3.
15
It is to be noted that the present invention in
volves supporting the manifold unit on or within
the converter in such a way that there is but a
single rigid or substantially rigid connection be
tween them.
In the illustrated form of the in
20
vention this rigid connection is supply conduit I5
(Fig. 2) which ?xes the position of supply main
I4 in relation to the converter wall. All other
parts of the manifold unit are capable of move
ment relative to each other and to the ?xed point 25
or junction of conduit I5 with main I4 so as to
ifold unit, which comprises manifolds E and mains
avoid rupture of connections or other injury, par
ticularly those movements induced by relative
temperature variations, as for example when
supply and outlet connections I5 and I8 through
their attachment to the converter wall and by
main I4 and tube sheet 6 pass from a phase in 30
which they are at substantially the same tem
perature to a phase in Which they are at widely

By removing cover 5a of the converter, and by
breaking joints I50, and I8a, the entire heat ex
change system can be lifted out of the converter
We claim as our invention:
1. In a converter for treating ?uids having an 35
upright casing providing adjacent manifolding
as an entirety, or it may be partly disassembled
and reaction chambers, the manifolding chamber
by ?rst detaching the transverse supply and out
being adjacent an end of said reaction chamber,
the combination therewith of apparatus adapted
to effect heat interchange within said reaction 40
chamber which comprises at least one manifold,
adapted to conduct heat exchange medium and
made up of nested inlet and outlet conduits, lo
let mains I4 and II whereupon manifolds E with
40 their associated elements D can be withdrawn in
dividually. In the event of use of a converter
which is much larger than that disclosed in‘ the
accompanying drawings, a number of the mani
folding units comprising parallel manifolds E and
45 transverse mains I4 and I1 would be provided, in
asmuch as there are limits to the permissible rel
ative movement of conduits II and I2 making up
manifold E when connected, in the manner il
lustrated, to a number of the nested tubular
50 elements D.
Movement of reactant ?uids and reaction prod
ucts to, within and from the converter may be
arranged as desired. If enclosing members III
for heat exchange elements D are imperforate,
55 as indicated in Fig. 3, the reactants could be
passed through the reaction chamber from end
to end by providing small perforations in upper
tube sheet 6, as shown in Fig. 3 and by similar
perforations in tube sheet 'I, as shown in Fig. 1.
By providing members
III with perforations
throughout those portions which are in reaction
chamber B, as illustrated in Fig. 1, and with
larger perforations above tube sheet 6, these mem
bers can be used to distribute reactant ?uids all
65 through the mass, if the ?uids are admitted to
manifolding chamber A, or to withdraw the re
action products from a multiplicity of points
within the mass if the reactant ?uids are ad
mitted‘ to manifolding chamber C‘. In this in
70 stance, the heat exchange ?uid could be utilized
to supply heat to the reactants for an endothermic
reaction by sending the same into manifolding
chamber A, and, conversely, it could be utilized
, to remove some or all of the undesirable or excess
75
reactants into manifolding chamber C and caus
ing the hot reaction products to enter the perfo
heat of an exothermic reaction by passing the
cated within said manifolding chamber, nested
spur tubes connected to and extending at least 45
approximately vertically from said manifold at
intervals into said reaction chamber, thereby to
provide for circulating heat exchange ?uid in
confined streams within said reaction chamber,
said spur tubes being rigidly fastened only to said
manifold, supporting structure located within
said casing adjacent said manifold and providing
a plurality of supporting surfaces horizontally
spaced from each other throughout the trans
verse dimensicns of said casing, and said heat
exchange apparatus, comprising said manifold
and said spur tubes, being freely supported on
said supporting surfaces so as to permit limited
relative horizontal movement of said heat ex
change apparatus with respect to other portions
of the converter, thereby to avoid stresses due to
unequal thermal expansions and contractions.

upright casing providing adjacent manifolding
and reaction chambers, the manifolding cham
