Example Embodiment

[0011] Embodiment 1: dissolve 500 grams of barium carbonate in water and make it into an aqueous solution with dilute sulfuric acid at a mass ratio of 1:0.2 of pure substance with a rotation speed of 120 rev / min in the reactor (1) with 1% surfactant. , in the reaction, barium sulfate is used to remove impurities, resulting in the formation of precipitated barium sulfate and carbon dioxide. Filtering (2) to obtain chlorine cake is barium sulfate and then drying (3), pulverizing (4), and packing to obtain 237.76 kilograms of precipitated barium sulfate. And 44.9 kg of carbon dioxide is compressed into a bottled product (5).

[0012] Implementation two: dissolve 500 grams of barium carbonate in water and make it into an aqueous solution with dilute sulfuric acid at a mass ratio of 1:0.7 of pure substance with a rotating speed of 300 rev / min in the reactor (1) with 3% surfactant, In the reaction, barium sulfate is used to remove impurities, resulting in the formation of precipita...

Abstract

The invention discloses a method for co-producing carbon dioxide by using superfine precipitated barium sulfate prepared by barium carbonate. The method is characterized in that barium carbonate and sulphuric acid react according to a specific proportion to generate barium sulfate and carbon dioxide, and the barium sulfate is dried, smashed and packaged to obtain a precipitated barium sulfate product; the carbon dioxide is compressed, liquefied and then filled into a steel cylinder to form a product. The method has the advantages of simple production technique and equipment, high yield and high profits, and overcomes the disadvantages of large operation amount of materials, low yield, complex and enormous technological equipment and the like of a conventional production method.

Description

Technical field: [0001] The invention relates to the technical field of chemical deep processing, in particular to a method for coproducing carbon dioxide with ultrafine precipitated barium sulfate prepared from barium carbonate. technical background: [0002] There are many ways to produce precipitated barium sulfate, mainly barium ore production. However, the production yield of this method is low, and a large amount of material transportation leads to complex and huge production equipment. The method of preparing precipitated barium sulfate with barium carbonate is simple and clear, especially the production of high-grade precipitated barium sulfate with low-grade barium carbonate, the production process and equipment are simple, the yield is huge, and the profit is very high. Invention content: [0003] The invention provides a method for precipitating barium sulfate prepared by using barium carbonate. The method has simple production technology and equipment, great y...
