Embodiment 1

[0023] Combined production of thionyl chloride (SOCl 2 ) and phosphorus oxychloride (POCl 3 ) process, from the top phosphorus oxychloride (PCl 3 ) enters, chlorine gas (Cl 2 ) and sulfur dioxide (SO 2 ) into the reaction tower system from the bottom of the tower to adjust the ratio of gas and liquid, and the reaction completed liquid enters the intermediate tank from the tower kettle for buffering to obtain thionyl chloride (SOCl 2 ) and phosphorus oxychloride (POCl 3 ) product mixture, rectification in the rectification tower after heating, and at the same time obtain the product thionyl chloride (SOCl 2 ) and phosphorus oxychloride (POCl 3 ), the product quality reaches the specified standard, and the yield is greater than or equal to 90%.

Embodiment 2

[0025] A carbon dioxide (CO 2 ) In the absorption device, the absorption liquid containing sodium carbonate enters the tower from the liquid inlet at the top of the tower, and the gas rich in carbon dioxide enters the tower from the gas inlet at the bottom of the tower. The gas-liquid two-phase cross-flow contacts through the trapezoidal plate-shaped liquid curtain in the tower to carry out phase transfer, and the carbon dioxide gas is transferred from the gas to the liquid phase. Adjust the ratio of gas and liquid, the reaction completed liquid enters the intermediate tank from the tower kettle for buffering, obtains the absorption complete liquid, and then decomposes pure carbon dioxide after heating.

Abstract

The invention discloses a gas absorption apparatus. The gas absorption apparatus comprises an upper seal (1), liquid inlets (2), gas outlets (3), tower sections (4), sealing washers (5), tower plates (6), observation ports (7), outer walls (8) of tower wall interlayers, gas inlets (9), tower bodies (10), liquid outlets (11) and a lower seal (12); the gas absorption apparatus is formed by the at least two tower bodies which are prolate and connected with on another through pipelines; and the tower plates (6) are rectangular. The gas absorption apparatus provided by the invention has the advantages of large mass transfer area, small resistance and relatively high mass transfer efficiency on the premise of ensuring great liquid holdup.

Description

technical field [0001] The invention relates to chemical production equipment, in particular to a situation of gas-liquid phase reaction or absorption contact in chemical production. It belongs to the technical field of gas-liquid mass transfer chemical equipment. Background technique [0002] Gas absorption device is a common equipment for gas-liquid heat transfer and mass transfer process. The flow behavior of the gas-liquid two phases in the tower has an important influence on the heat transfer and mass transfer efficiency of the plate tower. Conventional gas absorption device—tower equipment Considering the engineering factors of gas-liquid mass transfer equipment, the gas-liquid mass transfer is promoted by modifying the tray structure in the tower body or installing packing to pursue the largest possible specific surface area. Generally, in the plate tower operating in chemical production, the liquid flows downward from the downcomer, enters from the gap between the ...
