Title: Improvements in or relating to the purification of aromatic hydrocarbons
Inventor: MOLONY ORMSBY WILLINGTON
IPC: C10G17/09
Filed: 1960-07-12
Abstract: Aromatic hydrocarbons are freed from sulphur compounds by intimate contact with sulphur trioxide free from sulphuric acid and removing the reaction products from the aromatic hydrocarbon. The sulphur trioxide is preferably in the liquid form and is contacted with the hydrocarbon, e.g. benzene, toluene or xylene, by passing the latter at a Reynolds number above 3000 through a constriction and injecting the sulphur trioxide or by mixing in a rotary mixer.  The impurities and sulphur trioxide are separated by settling and the hydrocarbon washed with alkali, and if desired fractionated.  The examples describe the use of amounts of 0.40 to 2.22% by volume of sulphur trioxide based on the volume of benzene purified.  The process of Specification 855,774 is disclaimed.

Title: Concentration of solutions by crystallization
IPC: B01D53/00
Filed: 1963-06-20
Abstract: 973,729. Concentrating solutions by freezing. PHILLIPS PETROLEUM CO. June 20, 1963 [July 5, 1962], No. 24542/63. Heading F4H. In a process for concentrating a solution by freezing to form crystals in mother liquor, the crystals and liquor are separated in a confined zone and the pressure in said zone is maintained substantially above the vapour pressure of the mother liquor to prevent evolution of any normally gaseous or volatile component therefrom. As shown, beer from a fermentation stage 10 is passed to a tank 14 and thence via line 17 to a chiller 18 in which a slurry of icecrystals and beer concentrate is formed. The slurry is then passed to a separator column 19 having a heater 21 at its lower end and a filter 27 between its ends, the ice being forced downwardly in the column against a rising stream of melt water which is produced by the heater and is periodically forced upwardly by a pulseunit 24. Substantially pure water is extracted at 22 and beer concentrate through filter 27 and line 28 which leads to an accumulator 34. A vapour space is maintained in the latter by a liquid level controller 36 which controls a valve 37 in the accumulator outlet line 38. Part of the concentrate from the line 38 is refluxed to the chiller 18 via line 81 and the remainder is passed through a second chiller, separator and accumulator assembly 41, 42, 50, the concentrate leaving the accumulator 50 passing through a filter 54 to a storage tank 58. Carbon dioxide evolved during fermentation passes to a storage tank 12 which also receives carbon dioxide from accumulators 34 and 50 via valve-controlled lines 77 and 79. To prevent carbon dioxide from evolving in the separation column 19 and causing channelling of the ice mass therein the pressure in the column is maintained substantially higher than the vapour pressure of the beer concentrate which is approximately the pressure prevailing in accumulator 34. To effect this a pressure controller 63 which senses the pressures P1 and P2 in line 17 and accumulator 34, respectively, controls a valve 64 in line 17 to maintain P1 at from 50 to 100 p.s.i. above P2, while a second pressure controller 68 which senses pressure P1 and the pressure P3 in the outlet line 28 from the separator regulates a valve 33 in line 28 to maintain pressure P3 at from 5 to 100 p.s.i above P1. The pressure in separator column 42 is similarly controlled by pressure controllers 70 and 74 and valves 71, 48 and 49. The melt water from the separators 19 and 42. passes through valves 23 and 61, which are controlled in dependence on the temperatures in the lower parts of separators 19 and 42 respectively, to a tank 86. The beer concentrate in tank 58 may be reconstituted when desired by forwarding it to tank 86, to mix with the water therein, and thence to a carbonation tank 90 supplied with carbon dioxide from the storage tank 12. The process may be used to concentrate wires or fruit juices containing volatile esters or essences. Specification 807,100 is referred to.
