Sulfuric Acid Plants for Sale

Used two lines of 2,400 TPD per each (4,800 TPD in total), double absorption, Sulfuric Acid lines designed by MECS, and built in 1973 with upgrades completed by MECS in 1980, 1995, 2002, 2004, and 2013.

Used 1,650 TPD Sulfuric Acid Plant built in 1966. Sulfur is first melted in the sulfur day tank. The molten sulfur is pumped to a buffer pit, and then to sulfur burner. A waste heat boiler (#1) recovers the heat from the sulfur burner to generate sulfur dioxide. The SO2 proceeds to the converter, where it is converted to SO3. The converter consists of 4 beds of vanadium pentoxide (V2O5) catalyst. The first pass has 56,000 liters of catalyst, 2nd pass 62,400 liters, 3rd pass 77,000 liters and 4th pass 132,000 liters. A second waste heat boiler (#2) recycles the heat from the converter. The SO3 stream passes the economizer, which increases the efficiency of the operation, and then goes into a single absorbing tower. Here the SO3 is absorbed into water. The absorbing tower has 60 Mist eliminators, 5,569 cubic feet ceramic packing. The raw sulfuric acid solution goes to a drying tower which takes air from the main air blower for drying. The drying tower has mesh pads, 4,560 cubic feet ceramic packing. The sulfuric acid product of 98% is then pumped into an intermediate tank and through coolers before entering product storage tanks. The plant reliability is excellent and estimated to be around 98% on-line, with a budget of 12 days per year allocated for routine maintenance by a crew of 6 maintenance staffs. Plant turnarounds are typically taken every 3 years.

Used two lines of 1,300 TPD per each (2,600 TPD in total), single absorption MECS designed Sulfuric Acid lines built in 1965 with upgrades completed by MECS in 1994, 2002, 2009, and 2012.

Used 2,400 TPD Sulfuric Acid Plant built in 2000 and operated for only 10 years. It produces 98.5 - 99.5% sulfuric acid and fuming sulfuric acid (Oleum). Besides all the processing equipment of sulfuric acid production, the plant has its own utility facility including auxiliary boiler (60 ton/hr of steam), steam turbine generator (15 MW, Siemens), transformers (7 MW each). The plant is equipped with Honeywell DCS. Full documentation, including PFDs, P&IDs, operating procedures, process control logic, and equipment files, are available. Plenty of spare parts are available.

Unused 1,500 TPD double-absorption sulfuric acid plant for sale immediately available. Process designed by MECS. The plant has turn-down capacity of 650 TPD, can produce 32 tons/hour of medium-pressure steam and 80 tons/hour of high-pressure steam, and includes a 23.3 MW GE steam turbine (model 6-8 MC 8 IN). Sulfuric acid product has minimum concentration of 98.5%. Plant conversion (yield) 99.8%. Minimum 339 days per year of operation (26 days for scheduled maintenance). Downtime of major turnaround: 3 weeks per 18 months. The plant includes four process sections: Sulphur fusion / filtration; Production of gaseous SO2; Catalytic oxidation of SO2 to produce SO3; Absorption of SO3 to produce sulfuric acid. All the equipment is never installed. Ready for quick shipment.
