Abstract: A water-saving intake air cooling apparatus for a stationary internal combustion engine includes a primary intake air cooler, a high temperature side intake air cooler, and a low temperature side intake air cooler in an intake air passage upstream and downstream of a turbo charger. A first radiator transfers cooling water to an absorption chiller. The absorption chiller transfers cooling water to the primary intake air cooler and to the low temperature side intake air cooler. A second radiator transfers cooling water to the high temperature side intake air cooler. A third radiator cools lubricating oil flowing through a lubricating oil circulation space. Steam is generated by an exhaust heat boiler provided in an exhaust gas passage, and the steam is supplied to the absorption chiller as a heat source. Such use of the first, second, and third radiators, reduces the need for cooling water.

Abstract: To realize a water-saving intake air cooling apparatus for a stationary internal combustion engine, which can be operated in a region where water is valuable and an outside air temperature is high, a primary intake air cooler 22, a high temperature side intake air cooler 28, and a low temperature side intake air cooler 30 are provided in an intake air passage 24 on an upstream side and a downstream side of a turbo charger 26, while an absorption chiller 50 is provided to transfer cooling water to the primary intake air cooler 22 and the low temperature side intake air cooler 30, and a second radiator 44 is provided to transfer cooling water to the high temperature side intake air cooler 28. A first radiator 52 is provided to transfer cooling water to the absorption chiller 50, steam is generated by an exhaust heat boiler 34 provided in an exhaust gas passage 32, and the steam is supplied to the absorption chiller 50 as a heat source.

Abstract: Herein is disclosed a method of crystallization with the particle size distribution being controlled, characterized in that while crystals are being precipitated by vacuum concentration crystallization, the temperature of the slurry is periodically varied up and down during the concentration of the crystallization mother liquor (i.e., the slurry), which method is an excellent one free from the defects of the conventional methods.

Abstract: A process for production of a composition for animal feed, which comprisesspray drying a solution containing 5-95 wt. % based on the solids content of a solution of tryptophan or threonine, or a concentrate thereof, to make sprayed granules in a semi-dry state,depositing said spray granules in a mat form, andhot air drying said granules to produce granules having a water content of about 4 wt. % or less.
