Title: Improvements in or relating to heating gases and vapours
Inventor: CARTER AUSTIN GEORGE
IPC: F22D1/28
Filed: 1956-01-23
Abstract: 845,406. Combustible gases. POWER-GAS CORPORATION Ltd. Jan. 18, 1957 [Jan. 23, 1956], No. 2218/56. Classes 55 (1) and 55 (2). [Also in Group XIII] Gases or vapours are heated to a high temperature, particularly for use in an endothermic reaction such as that between steam and carbonaceous material to produce water gas, between steam and hydrocarbons to produce gases such as synthesis gas, between carbon dioxide and carbon to produce carbon monoxide and between carbon dioxide and hydrocarbons to produce gases such as synthesis gas, by means of a cyclic process. In a first stage air is passed by blower 27 and valve 31 to the cold end 4 of a regenerator 1, is heated in the checkerwork 2 and is combusted with gaseous or liquid fuel fed in at 47. The combustion gases heat up the checkerwork 6 in regenerator 5 and pass through valve 15, conduit 12 and waste heat boiler 56 to the stack 60. Subsequently steam, or other vapour or gas to be heated, is fed in at 41 and purges the regenerators, the products escaping through valve 14 and conduit 12 to the stack 60. In a second stage steam, or other vapour or gas is passed in at 41, is heated in regenerator 5 and passes through line 11 to the reactor 61, which is fed with reactant at 63, the resultant gases passing through cooler 62 and valve 20 to storage. A purge follows during which air passes through valve 34 to regenerator 5, through conduit 10 to regenerator 1 and escapes to stack 60 through valve 14 and conduit 12. The third stage follows with air passing up regenerator 5 and combusting with fuel fed in at 44 to heat cheekerwork 2 before passing to the stack. In the following purge, steam or other vapour or gas passes up regenerator 1 from inlet 38 and vents the combustion products to stack 60 through valve 15 and conduit 12. In the fourth stage steam or other vapour or gas from inlet 38 is heated in checkerwork 2 and passes to the reactor 61. If oils or other hydrocarbons are reacted with the highly heated vapour or gas, these may be fed in at 54 or 51 during the second and fourth stages, respectively, in which case the resultant gas is passed to a wash-box 64 instead of reactor 61. If oil is fed in at 51 and 54 the fuel inlets 44, 47 may be omitted, the same oil being used for the reaction and for heating the regenerators. The waste heat boiler 56 may be by-passed by conduit 59 and damper 65. Specification 740,482 is referred to.

Title: Improvements in and relating to processes and apparatus for continuously crystallizing sugar solutions
IPC: C13B30/02
Filed: 1948-01-30
Abstract: <PICT:0651410/III/1> Sugar solutions are crystallized by submitting the solution, saturated at a high temperature and charged with seed crystals, to several stages of increasing vacuum whereby it is continuously evaporated without supply of heat, the differences in vacuum between succeeding stages being maintained such that the differences progressively increase towards the delivery end of the process.  The heat of evaporation is withdrawn from the mass itself, and the rate of cooling is such that a uniform growth of crystals is secured.  Saturated sugar solution from steam-heated evaporator 1 is mixed with seed grain in vessel 5, and the mass is then supplied through pipe 7 to crystallizing vessel 8.  This crystallizer is divided into compartments by partitions 9, and each compartment has a vapour take-off pipe 10 which terminates below water in a vessel 11 provided with a water-overflow 14.  The immersed lengths of successive pipes 10 decrease in the direction of flow of the solution, and the difference in length between the immersed portions of adjacent pipes increases in the same direction.  Vessel 11 is connected by pipe 13 to a condenser maintained at sub-atmospheric pressure.  As the mass passes through the compartments of crystallizer 8, evaporation takes place at lower and lower temperatures, and the crystals grow uniformly.  The mass is stirred by members attached to shaft 15 during crystallization.  The crystallized-mass discharged from the last compartment through pipe 17 is either sent to cooler 16 where the growth of crystals is continued, or it is added as core-grains to another sugar solution for obtaining a coarse-grained product.
