Patent EP-0330351-A1 (EP)
Inventor: GUENKEL ALFRED ALEXANDER DEPAR
IPC: C01B21/44
Filed: 1989-02-13
Abstract: The invention provides integrated continuous processes for concentrating "weak" nitric acid and concurrently reconcentrating the spent dehydrating agent used to break the nitric acid azeotrope to obtain "strong" nitric acid, the processes involving direct coupling of the nitric acid concentration with the reconcentration of the spent dehydrating agent so that less energy input is required than in equivalent prior art processes. The major proportion (18) of the feed "weak" nitric acid is vaporized (20) before being fed counter-­currently into a column (10) to contact (in section 4) a large volume of the dehydrating agent, this vaporization being one of the two major sources of energy input, the second being through the reboiler (54) at the bottom of the column. Engergy input is balanced by energy rejection through condensation of strong nitric acid vapor and water vapor. The nitric acid vapor injected into the lower part of the column (section 4) is subsequently contacted in succession with a mixture (28) of nitric acid and a portion of the dehydrating agent (in section 3) to further increase the strength of the nitric acid vapor, then with a third portion of the dehydrating agent (section 2) and finally a small reflux of concentrated "strong" nitric acid (44) to remove further water and residual dehydrating agent from the concentrated "strong" nitric acid vapor in the upper part of the column (section 1). The spent dehydrating agent is reconcentrated by flashing under vacuum or alternatively through evaporative cooling with air without further substantial energy input, and is recycled back to the nitric acid concentration column without being cooled, avoiding consequent rejection of energy. The preferred dehydrating agents are aqueous solutions of sulfuric acid and of magnesium nitrate.

Abstract: A microwave watercut monitor includes a test cell having a petroleum stream flowing through it while permitting the microwave energy to enter the test cell. A microwave source provides microwave energy to a circulator which in turn provides the microwave energy to an antenna. The antenna provides the petroleum stream in the test cell with the microwave energy and receives reflected microwave energy back from the stream. The reflected microwave energy is provided by the antenna to the circulator which in turn provides the reflected microwave energy as test microwave energy. Indicator apparatus provides an indication of the watercut of the petroleum stream in accordance with the phase difference between the source provided microwave energy and the test microwave energy. In one embodiment a detector assembly is connected to the circulator and detects the intensity of the test microwave energy to provide a corresponding intensity signal. 
     The indicator apparatus is connected to the circulator to the microwave source and to the detector assembly to provide an indication of the watercut in accordance with the intensity signal and the phase difference between the source provided microwave energy and the test microwave energy.
