Title: Method of obtaining distilled water from sea or estuarine water
IPC: C02F1/04
Filed: 1952-07-04
Abstract: <PICT:0741815/III/1> In a method of obtaining distilled water from sea or estuarine water by evaporation and subsequent condensation, heavy scale formation on the heat-exchange surfaces of the evaporator is avoided by subjecting the water, before it enters the evaporator, to pressure and bringing it into intimate contact with saturated steam at a temperature not less than 130 DEG F whereby bicarbonate and carbonate ions are converted into carbon dioxide gas, water and hydroxyl ions.  The carbon dioxide is vented from the system.  A suspension of magnesium hydroxide is formed in the water, but this does not cause scale formation.  In a preferred embodiment, the steam produced in the evaporator itself is passed through the direct contact heating vessel on its way to the condenser.  The evaporator may be of the multiple effect type, in which case there may be a plurality of contacting vessels.  In the Figure evaporator 15 is heated by coil 14 which is supplied with steam through pipe 1.  The raw water is pumped from tank 5 through the cold-pass of condenser 7, then through air-ejector condenser 8 and heat-exchanger 9 into the top of the distributing chamber 11 of direct-contact heating vessel 4.  The water passes through sprays 12 into the steam space of vessel 4.  This vessel is divided into three compartments by ribs 32, which have passages so that the water level in the bottom of the vessel is equalised.  Steam from the evaporator 15 is introduced into vessel 4 through pipe 20 and perforated pipes 3, and scrubs the water in the base thereof.  The treated water passes over weir 33 and then flows to the evaporator via pipe 34.  After passing through the water in the base of vessel 4, the steam leaves through pipe 13, and flows through heat-exchanger 9 to condenser 7.  The distilled water is withdrawn from condenser by pumps 21, and is collected in tank 22. Air and carbon dioxide are withdrawn from condenser 7 by ejector 23 and discharged into condenser 8, whence the gases are vented by pipe 26 while the condensate is collected in tank 19.  Residual brine is withdrawn from evaporator 15 via weir 35 and pump 30.  The condensate from coil 14 is withdrawn by pump 18, and discharged into tank 19

Title: Improvements in the manufacture and production of paraformaldehyde
IPC: C08G2/08
Filed: 1927-07-01
Abstract: 296,847. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 1, 1927. Formaldehyde; :paraformaldehyde. - Paraformaldehyde is obtained from the products resulting from the catalytic oxidation of methanol by washing the products, preferably after cooling, with a warm strong solution of formaldehyde. It is preferred to cool the products only to such an extent that the temperature of the washing liquid is maintained sufficiently high to preclude the deposition of paraformaldehyde in the liquid during the washing process. An inert gas, such as nitrogen, may be added to the reaction products prior to or during washing. In an example, methanol vapour mixed with air and nitrogen is catalytically oxidized at 500‹ C. and the reaction products are cooled to about 50‹ C. and then washed with a 60 per cent solution of formaldehyde, the temperature of which should not exceed about 50‹ C. The washing liquid is drawn off as its volume increases, its concentration being retained under the working conditions, and the withdrawn liquid, after a short standing at ordinary temperature, changes to a paraformaldehyde paste. The formaldehyde in the residual gases is recovered by washing with water. Specification 267,768 is referred to.
