This is an important process in industries such as fertilizers, petrochemicals, dyes, explosives, and metallurgy.\n\n🔧 Methods of Sulphuric Acid Concentration\n1. Evaporation Under Vacuum\nPrinciple: Water is removed from dilute sulphuric acid by boiling under reduced pressure, using heat exchangers.\n\nEquipment: Often done in a falling film evaporator, wiped film evaporator, or rotating disk evaporator made from corrosion-resistant materials (e.g., glass, PTFE-lined steel, silicon carbide).\n\nTemperature: Typically around 100–150°C, depending on the vacuum level.\n\n2. Distillation (for Lab Scale)\nIn lab settings, dilute acid may be concentrated by careful distillation up to ~98.5%.\n\nAbove 98.5%, H₂SO₄ starts to decompose, releasing SO₃ and water.\n\n3. Sulphur Trioxide (SO₃) Absorption\nUsed industrially to increase H₂SO₄ concentration beyond 98.5% by absorbing SO₃ gas into 98% H₂SO₄ to form oleum (fuming sulphuric acid).\n\nThe oleum can later be diluted back to desired concentrations.\n\n", "price": 0.0, "discountamount": 0.0, "currencycode": "INR", "priority": 1000000, "isfreeshipmentavailable": false, "shipmentduration": 1, "_keywords": [ "98 h₂so₄", "important process", "985 h₂so₄ starts", "desired concentrations", "diluted back", "careful distillation", "lab scale", "100150c depending", "corrosionresistant materials", "reduced pressure", "metallurgy methods", "higher levels", "solution typically", "dilute concentrations", "increase h₂so₄ concentration", "dilute sulphuric acid", "absorbing so₃ gas", "decompose releasing so₃", "heat exchangers equipment", "vacuum principle water" ], "isarchived": false, "isavailable": true, "applicationid": null, "productindex": 5, "imageuri": "https://productimages.withfloats.com/actual/682dad44717b3915de0bb3b7.jpg", "tileimageuri": "https://productimages.withfloats.com/tile/682dad44717b3915de0bb3b7.jpg", "images": null, "totalqueries": 0, "gpid": null, "groupproductid": null, "createdon": "2025-05-21T10:38:18.593Z", "updatedon": "2025-05-21T10:38:58.857Z", "buyonlinelink": null, "producturl": "http://WWW.BHUMISCIENTIFIC.COM/products/sulphuric-acid-concentration/5", "availableunits": -1.0, "iscodavailable": false, "isprepaidonlineavailable": false, "maxcodorders": 0, "maxprepaidonlineorders": 0, "uniquepaymenturl": null, "brandname": "", "category": "Technical Products", "tags": [ "Sulphuric Acid Concentration in Vadodara" ], "variants": false, "keyspecification": null, "otherspecifications": null, "pickupaddressreferenceid": null, "paymenttype": "None", "producttype": "products", "hsncode": null, "gstslab": 0.0, "isnotforsale": false }, { "_id": "6836ec2a8821196bfdb95fbd", "fptag": "BHUMISCIENTIFIC", "merchantname": null, "customwidgets": null, "externalsourceid": null, "name": "Glass Vessels & Stirrers", "description": "Glass vessels & glass stirrers provide the best solution for all requirements encountered in production processes because of the wide range of glass vessels available.
