摘要： A process for the management of by-product tetranitromethane (TNM) which avoids the hazards of the prior art isolation or extraction procedures. A selected in-plant liquid or vapour stream, or a reactor off-gas stream from nitration or nitric acid oxidation plant, which contains TNM, is heated to effectively pyrolyse the TNM without undue losses of nitric acid values.

摘要： An absorption tower for absorbing sulphur trioxide in sulphuric acid having distinct upper and lower packed absorption zones wherein substantially all of the sulphur trioxide is absorbed by the sulphuric acid in the lower zone, while in the upper zone the depleted gas stream is significantly cooled. The two zones receive feed acids of different temperatures and different acid irrigation rates. The tower allows of improved energy recovery while providing for environmentally acceptable emission standards.

摘要： Certain continuous methods for monitoring the quality of ZnSO₄ electrolyte lose sensitivity when the electrolyte contains Sb (V). The sensitivity can be increased by electrochemically reducing Sb (V). A sample of electrolyte which contains impurities including Sb (V) and which may also contain polarization affecting agents is passed through a test cell containing an elongated moving cathode having a predetermined area exposed to the electrolyte, an anode and a reference electrode. A substantially constant current in the range of 0.01 to 0.20 A/cm² is applied to the electrodes and the cathode is moved with a speed sufficient to obtain measured values of the cathode polarization potential of zinc deposition on zinc. The measured values are related to the concentrations of impurities, polarization affecting agents, or both and to the concentration ratio between impurities and polarization affecting agents, and the process for zinc recovery is adjusted in response to these relations to obtain optimum zinc recovery.

摘要： This invention relates to a process for the production of concentrated sulphuric acid from waste sulphuric acid characterized in that said waste acid is subjected to microwave energy for a sufficient period of time to effect production of water vapour, whereby said waste acid is concentrated to a desired degree; removing said water vapour; and collecting said concentrated acid. It also relates to apparatus for the production of concentrated sulphuric acid from waste sulphuric acid characterized by container means for containing said waste acid, microwave means for subjecting said waste acid in said container means to microwave energy for a sufficient period of time to effect production of water vapour whereby said waste acid is concentrated to a desired degree, and means for removing said water vapour.

摘要： A continuous process for the generation of sulphur trioxide from oleum suitable for use in the sulphonation of organic compounds which comprises continuously introducing oleum feed to a sulphur trioxide desorption tower; continuously introducing a dry feed airstream comprising recycled dry feed air stream to the desorption tower, whereby a gaseous mixture of sulphur trioxide in air is produced; collecting spent oleum from the desorption tower; introducing the gaseous mixture to a sulphpnation reactor; and recycling spent gaseous mixture from the reactor to the desorption tower as recycled feed air. The process offers reduced environmental pollution and operating costs.

摘要： 57 An apparatus and method is provided for measuring the continuity and resistance of electric circuits, particularly electric wire circuits due to galvanic currents. A constant current from a cell is passed through the electric circuit to be tested and through a reference resistor where the voltages are measured to derive the resistance of the circuit. The measured voltages are sensed with a converter converted to a resistance measurement and displayed. The presence of spurious voltages is compensated for by connecting a galvanic current storage capacitor in the circuit, passing a reference current through the reference resistor and the circuit and comparing the voltage across the reference resistor with the voltage across the circuit and storage capacitor to derive a resistance reading. The reading is converted to a digital display. The method and apparatus provides a quick, convenient means of testing blasting circuit continuity in the field in the presence of stray current caused by in-earth galvanic action.
