Abstract: A PROCESS FOR TREATING CONTAMINATED WASTE WATER FROM MANUFACTURING PROCESS IS DISCLOSED. THE WATER CONTAINS, FOR EXAMPLE, HYDROGEN SULFIDE, AMMONIA AND PHENOL IN THE PRESENCE OF NON-VOLATILE AND STRONGLY ALKALINE IONS. AN AMMONIUM SALT OF A STRONG MINERAL ACID SUCH AS AMMONIUM SULFATE IS ADDED TO THE CONTAMINATED WASTE WATER AND THE AMMONIA AND HYDROGEN SULFIDE ARE STRIPPED AWAY. THE PHENOL SEPARATES AS AN OILY LAYER AND MAY BE REMOVED. THE AMMONIUM SULFATE NEEDED FOR THE PROCESS MAY BE GENERATED DURING THE PROCESS BY TREATING THE STRIPPED AMMONIA WITH SULFURIC ACID.

Abstract: A heater comprises two concentric vertical tubes having a flame projecting down in the inner tube with the lower end of at least one of the tubes immersed in a tank of liquid, as a salt solution or an acid solution to be evaporated, condensed, and recirculated in the annulus between the tubes. Helical spiral vanes are formed in the annulus for delaying and spinning a thin, consistent film of the liquid over the contiguous surfaces of the tubes for producing considerably decreased operating temperatures of the tubes resulting in greatly decreased corrosion of and deposit formation on the heater.

Abstract: A method of initiating in situ combustion in a subterranean hydrocarbon-bearing formation wherein a substance capable of reacting with hydrogen peroxide is introduced into the formation via a well bore and thereafter a mixture of hydrogen peroxide containing from 10 to 20 percent by weight of water is injected to effect an exothermic reaction thereby to increase the temperature of the formation adjacent the well bore to the ignition temperature of the hydrocarbons contained therein and resulting in ignition of those hydrocarbons and the initiation of an in situ combustion.

Abstract: THIS INVENTION CONCERNS A PROCESS FOR INCREASING THE HARDENING RATES IN THE PREPARATION OF EPOXIDE RESINS USING DICARBOXYLIC ANHYDRIDES AS HARDENING AGENTS. THE INCREASE IN HARDENING RATES IS ACHIEVED BY REACTING MIXTURES OF BASIC NITROGEN-CONTAINING GLYCIDYL COMPOUNDS WITH DICARBOXYLIC ANHYDRIDES. AN OPTIONAL ASPECT OF THE INVENTIVE PROCESS IS TO CONDUCT THE ABOVE REACTION IN THE PESENCE OF ALKYD RESINS AND/OR SOLVENTS.
