No. 3145, F-31053 Toulouse, Actual Inventor' Address for Service: DIMITRIOS ABRIANOJ BELTS, PIERRE CHINAL and JEAN FRANCOIS PRI AT EDWD, WATERS SONS, 50 QUEEN STREET, MELBOURNE, AUSTRALIA, 3000, Complete Specification for the 1I,-.,entlon eri titled: NEW PIPE REACTOR Tho follk wing statement Is a full deicrlption of this Invention, Including the best method of performing It known to, I-IS NEW PIPE REAC; R The present application relates to a new pipe reactor having improved output and flexibility.
Pipe reactors are well known. They are made out of a length of pipe having a rather small diameter and containing no stuffing. Pipe reactors generally used are horizontally set or stand at small iqle (at most 450) relative to an horizontal line. They have an inside diameter ranging between 200 and 10 mm and a length ranging between 1,50 and 10 m. The ratio length/ diameter is generally not less than They are used for neutralizing with ammonia, acids or mixtures of acids such as slurry obtained by attack of natural phosphate by an exces', of sulfuric acid, phosphoric acid and mixtures of these acids. More often they are used for the manufacture of ammonium phosphates or ammonium polyphos- S phates.
f,5 For a good running of the pipe reactor the reactives must be mixed as thoroughly as possible. If mixture is not thorough enough the output j of pipe reactor will be essentially constituted by a dense liquid phase es- S. sentially made out of more or less acid constituants which flow out of the I pipe and of a gaSeous phase made out of ammonia and steam. Therefore ammonia S0 losses are important. When the mixture is thorough no more dense phase is produced. A mist of droplets of more or less GoAr.ated. solution or of dry a particle is formed which can be easily separated from steam. Furthermore the unit should be able to treat as wide as possible range of amounts of reactives.
Different proposals have been made in order to improve the mixture of reactives at the head of the pipe reactor. It has been for example proposed to introduce one of the reactives through a sparger (French Patent 2,172,826). But this parger is liable to get clogged. It has also be proposed to use a jet reactor in which acid and ammonia are introduced t'rough 1 two concentric pipes and are mixed by using an helicoidal screw followed by a convergent. (Phosphorus and Potassium n° 45, 1970, pp. 18-19). But clogging takes place also between spiral screw and wall of the pipe reactor.
The present application relates to a new pipe reactor comprising a zone for the introduction of reactives a reaction zone and a nozzle for the output of reaction product characterized in that the pipe reactor is provided with a convergent-divergent or a convergent fitted in the reaction zone, just after the zone of introduction of reactives and a convergent-divergent or a convergent fitted at the output end of the reaction zone, just before the nozzle for the output of reaction product.
o According to the length of the pipe reactor and to reactives used one at-e-st three convergents-divergents or con\ergents areAplaced beto ween the two above defined convergents-divergents or convergents, 0 It has been noted that the use of these convergents-divergents or .'15 convergents improve the mixing of reactives without plugging risks. The flexibility is also highly improved.
o -00 The description given hereunder as well as the annexed figure will allow to understand better the invention.
oo Pipe reactor comprises a zone for the introduction of 0 va4 ea&Qt.s, a reaction zone and a nozzle for the output of reaction o, products.
According to the embodiment shown on annexed figure a convergentdivergent is fitted at the input of reaction zone According to the invention this convergent-divergent could be replaced by a convergent but (6) convergent-divergent gives a better result. A further conerentvergent-divergent is disposed at the output of reaction zone This convergent-divergent can also be replaced by a convergent. The d44-s4e1of a convergent-divergent) at the output of reaction zone rather than a corvergent is less advantageous than for the convergent-divergent at the input of reaction zone 2 According to the embodiment illustrateda convergent it set between convergents-divergents and A convergent-divergent could be substituted to convergent But it must be noted that according to the present invention their can be no convergent According to the length of the pipe reactor, 'i reaction zone up to 3 convergents-divergents or convergent can be between convergents-divergents anid Therefore reactives rgtting out of the zone of introduction of reactives are accelerated by the convergent-divergent thus improving the mixing of reactives at the beginning of the reaction. Convergent-divergent brings about a further mixing just before the output of the reaction product.
According to the present application reaction zone can be as- 2' sociated to any zone for the introduction of reactives. According to illuso° trated embodiment acid or mixture of acids is introduced into zone (2) o" through a feed pipe which opens perpendicularly in the pipe reactor There could be many feed pipes opening perpendicularly or tangentially in the pipe reactor As shown on the annexed figure two concentric, axially set feed pipes and (10) for feeding respectively water and/or I o washing waters and ammonia, the feed pipe (10) for water and/or washing o *20 brines feeding being inside the feed pipe for ammonia. The feeding pipe could be removed. Therefore feed pipe for ammonia liquid or gaseous S would remain.
The output nozzled pipe can be a frustoconial nozzle as shown on annexed figure. The nozzle could be also dissymetrical or bended in order to direct the spout of reaction product.
EXAMPLE
In a pipe reactor similar to that represented on annexed figure a mixture of ammonium phosphate and ammonium sulfate is prepared by reacting 26 phosphoric acid, 93 sulfuric acid and liquid ammoni.
-3a) when no convergent-divergent or convergent are set in reaction zone (3) 11 t/h to 5,5 t/h of liquid ammonia 26 t/h to 13 t/h of sulfuric acid 11 t/h to 5,5 t/h of phospnoric acid can be treated. The fl-xibility is about 1/2, b) when the reaction ,ne contains convergents-divergents and convergents as illustrated on annexed figure 2.t/h to 11 t/h of liquid ammonia t/h to 26 t/h of sulfuric acid 2 t/h to 11 t/h of phosphoric acid can be treated. The flexibility is about 1/6.
