Abstract: Disclosed are a cooling water-saving device for a cooling tower, and a wet cooling tower. The cooling water-saving device includes indirect heat exchange devices and a water collecting tank. The inner wall of a cooling tower shell is sealed by the water collecting tank. The indirect heat exchange device includes a heat exchange channel and a heat insulation channel. The heat insulation channel penetrates through the bottom of the water collecting tank, and the bottom inlet of the heat insulation channel communicates with air entering from the bottom of the cooling tower shell. The heat exchange channel for shielding water drops is arranged at the top outlet of the heat insulation channel, and the top of the heat exchange channel extends into an air outlet in the upper part of the cooling tower shell. The lower outlet of the heat exchange channel communicates with a rain area.

Abstract: A method of preparing epoxypropane by direct epoxidation of propylene includes the steps of contacting a mixed gas consisting of a reaction feed gas and a diluent gas with a catalyst to carry out reaction under reaction conditions of propylene epoxidation to prepare epoxypropane. The reaction feed gas contains propylene, oxygen gas and hydrogen gas while at least a portion of the diluent gas is a gaseous olefin. Using gaseous olefin as at least a portion of the diluent gas to perform propylene epoxidation that can significantly extend service life of the catalyst, effectively reduce the used amount of diluent gas, and improve the reaction selectivity and propylene conversion rate.

Abstract: A method and system for preparing epoxypropane by direct epoxidation of propylene includes the steps of subjecting a mixed gas of a first feed gas and a second feed gas to a contact reaction with a catalyst under reaction conditions of propylene epoxidation to prepare epoxypropane. The first feed gas contains oxygen gas and is free or substantially free of hydrogen gas. The second feed gas contains hydrogen gas and is free or substantially free of oxygen gas. The first feed gas and/or the second feed gas contain propylene, at least one of the first feed gas and the second feed gas further contains a diluent gas. The method can be used for reducing dosage of diluent gas, preferably recycling the tail gas, thereby significantly increasing the conversion rate of propylene without compromising the service life of catalyst.

Abstract: An information classification processing method of a carbonate reservoir and an information data processing terminal. The method includes: determining rock types; determining reservoir types on the basis of different rock types; and in accordance with the determined reservoir and rock types, performing porosity and permeability intersection by utilizing measured data; fitting a curve to obtain a porosity-permeability relation formula; and calculating permeability by utilizing the formula. According to the present invention, complex carbonate reservoirs in the Middle East can be classified, and porosity-permeability relations are respectively established, thereby increasing interpretation accuracy of permeability. According to the present invention, the reservoir types and the rock types can be rapidly and systematically classified, and clear porosity-permeability relations are obtained, so that interpretation of the permeability in oil reservoir exploitation is more accurate.
