Product details
Asia Chemical Engineering Co., Ltd. is one of the most reliable manufacturers and suppliers of sulphuric acid plant in China. Please rest assured to wholesale cost-efficient sulphuric acid plant from our factory. Good service and reasonable price are available.
Custom sulfuric acid plant with 3+1 double contact double absorption process, full waste heat recovery, low SO₂ emission. Supply EPC/MPC one-stop service for fertilizer, metallurgy, chemical industry, 98% concentrated sulfuric acid output.
Product Overview
Our factory supplies full-set sulfur burning sulfuric acid production line, adopt mature DCDA double conversion double absorption technology, customized capacity from 10kt/a up to 300kt/a (e.g. 100kt/a sulfuric acid plant as standard model).
The whole plant includes sulfur melting section, sulfur furnace & conversion section, dry-absorption section, waste heat recovery system, DCS automatic control system, finished acid storage and tail gas treatment unit. Raw material is solid bright sulfur ≥99.9%, stable to produce GB standard 98% concentrated sulfuric acid, optional oleum production.
Core Process Technology
We adopt integrated process: dynamic sulfur melting + liquid sulfur pressure filtration + 3+1 four-bed double conversion + 98% acid drying + medium-high temperature double absorption + fan behind drying tower + full waste heat steam recovery.
Melting & Filtration: Low-energy rapid melting tank + filter to remove impurities, stable refined liquid sulfur supply.
Sulfur Combustion: High-pressure sulfur gun mechanical + hot air dual atomization, complete sulfur burning.
Conversion Unit: 3+1 double contact design, SO₂ total conversion ≥99.8%, ultra-low tail gas emission.
Dry & Absorption: Three-tank two-circuit acid cycle, effectively suppress acid mist, reduce SO₂ in finished acid & exhaust.
Heat Recovery: Waste heat boiler, high/low temp superheater & heat pipe economizer arranged to generate 3.82MPa superheated steam for power or factory heating.
Air Fan Layout: Fan installed after drying tower, improve heat utilization & clean workshop environment.
Main Technical Advantages
1、High Environmental Standard: SO₂ exhaust ≤400mg/Nm³, fully meet GB20132 & international emission standards, few solid waste slag.
2、High Energy Saving: Full waste heat recovery system generates large amount of steam, cut power & fuel cost greatly.
3、Anti-Corrosion Equipment: Conversion tower, absorption tower, acid cooler lined with acid brick / 316L alloy, long service life, low maintenance.
4、DCS Automatic Control: Centralized monitoring for temperature, pressure, acid concentration, safety interlock to avoid misoperation, fewer workers needed.
5、Flexible Customization: Adjust layout, capacity, steam output according to local altitude, water & power condition.
6、Safe Operation: Complete fire prevention, noise reduction, corrosion protection & dust-proof design for labor protection.
FAQ：
Q1 What raw material for this sulfuric acid line?
Solid bright sulfur ≥99.9% purity, low ash & moisture.
Q2 What concentration acid can you produce?
Standard 98% concentrated sulfuric acid; oleum & liquid SO3 equipment optional.
Q3 Can you supply full EPC project including overseas installation?
Yes, we offer complete turnkey service from design to formal production.
Q4 How about the waste heat utilization?
Max waste heat recycled to produce high-pressure steam for factory heating or power generation.
Q5 Is the plant environmentally friendly?
DCDA high conversion rate reduces SO2 discharge, small amount sulfur slag can be recycled.
