to produce sulfuric acid SO3 H2O H2SO4 H -200 kJ mol-1 The circulating sulfuric acid must be maintained at about 98% concentration and 70C to maximise the absorption efficiency. The acid strength is important because the vapour pressure of sulfur trioxide above sulfuric acid is at a minimum at an acid strength of 98% (see Figure 3 ...
Sulfuric acid is the largest-volume industrial chemical produced in the world (200 million tons per year). Concentrated sulfuric acid (93-98 %) is used in the manufacture of fertilizers, explosives, dyes, and petroleum products. The starting material for sulfuric acid manufacture is clean, dry sulfur dioxide (SO2) gas.

The 7076% acid from the tower plant is used for dilution in the absorption circuit in the contact plant. The SCF off-gas is treated in a
Aug 26, 2018 Sulfuric acid plants use sulfur or sulfur dioxide that is a by-product from other industries. To maximise their conversion of sulfur dioxide to sulfur trioxide most plants now use a double absorption process. Any unreacted gas from the absorption tower is passed over the catalytic beds again and re passed through the absorption tower. This ...
Sulfuric Acid (H 2 SO 4) Manufacturing Process Contact Process. Sulfuric acid is one of the most important chemical produced in the world. Sulfuric is used in other chemical industries and have many uses in laboratories too as a chemical compound. In this tutorial, we are going to learn about followings.
It is necessary to distinguish the main ores as indi- cated in Table 2.1. f14 2 Processes of Manufacture of Sulfuric Acid The concentration (vol.%) of SO2 on the plant gases determines the total volume of gases handled. Any air injected into the system is additionalbut this is gener- ally a small amount.
The overall copper process is shown in Figure 4-2 this block diagram also shows the sulfuric acid plant that processes the sulfur dioxide generated in the roasting and converting steps. The production of sulfuric acid from a copper smelter requires smelter process gas with an SO2 concentration in the
Dec 14, 2020 Abstract. The results of investigations into Pb withdrawal with a NaCl solution from the slime of sulfuric-acid production of the Balkhash copper-smelting plant (BCP) to produce a sediment suitable for physical studies of the material composition of Se and other elements contained in the slime that are of interest from the viewpoint of their recovery, in particular, Re, I, and Hg, are presented.

If this limit were exceeded then an environmental S02 pollution would occur. 1.2 Sulphuric acids plants Plant I can produce 1500 MTPD of sulphuric acid, while Plant 2 can produce 2350 MTPD.
Control of SO2 from smelters is commonly performed in a sulfuric acid plant. Use of a sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas containing minimum SO2 concentrations, usually of at least 3 percent SO2, be maintained. Table 12.3-1 shows typical average SO2 concentrations from the various ...
12-14 %-vol. prior to being processed in the sulphuric acid plant. This dilution in turn enlarges the acid plant equipment by a factor of 2-3 and hence causes an equivalent increase of the related capi-tal and operating cost. As the smelter gas concentration increases, so will the feed
when upgrades to the smelter were implemented, the sulphuric acid plant could be converted to a double absorption plant that would allow it to handle higher SO 2 concentrations and produce more sulphuric acid.The acid plant has been designed based on existing converter
