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.
