Abstract: PURPOSE:To produce NH3 and SO2, both having high purity, efficiently under a relatively mild reaction condition by recovering ammonia then SO2 successively produced by the reaction of ammonium sulfate with a metal oxide or metal hydroxide, then circulating the metal oxide. CONSTITUTION:(i) Ammonium sulfate is allowed to react with a metal oxide or hydroxide at <=200 deg.C to generate ammonia, water, and metal sulfate, and the ammonia is recovered. (ii) Then, the metal sulfate is decomposed in the presence of a reducing agent to generate thus a metal oxide and SO2, and the SO2 is recovered. (iii) Further, the metal oxide is recycled to the stage (i) as it is or after transforming to a metal hydroxide. The reaction between the ammonium sulfate and the metal oxide or metal hydroxide is carried out in at least two sequential reactors. It is preferred that the reaction temp. in the first stage reactor is 60-100 deg.C, pref. 70-90 deg.C from view points of improvement of recovering rate of NH3 and saving of energy consumption.

Title: Solar pond
Inventor: TAKAYANAGI MIKIO
IPC: F24J2/00
Filed: 1987-03-13
Abstract: PURPOSE:To provide a solar pond having no deterioration in performance by a method wherein a sheet material at a side wall other than a non-convection flow layer of a solar pond is of a sheet material having a high rate of reflection. CONSTITUTION:Although a bottom surface and a side wall of a thermal accumulation layer 4 of a solar pond 1 are covered with a black sheet 5 in order to improve a rate of absorption of solar light, a side wall and a ground part other than a non-convection layer 3 are covered with, for example, a white sheet material 6 having a low optical absorption and a high rate of reflection. Due to this fact, the solar light is not absorbed by the sheet material 6, but most of it are reflected by the sheet material and reach a thermal accumulation layer 4 and effectively accumulated there. Thus, an abnormal heating is salt water at the sheet material and a part near the sheet material is not produced, and a gradient in concentration can always be kept constant and a thermal loss can be prevented from being increased upwardly. This may be helpful for increasing the temperature of the sheet material through a direct radiation of solar light and preventing the deterioration of the material.
