In sulfur acid plants, turbo compressors provide combustion air for sulfur burning. Preheat systems fans are used for acid regeneration.
In ammonia plant centrifugal compressors are used in air separation units. Exhaust fans evacuate residual gases from reactors and capacities. Periflow compressors integrate CO2 gas drying process for transport and reinjection cavities or in oil wells.
In urea plant, turbo compressors provide atomising air for the fluidised bed, lobe blowers are used for product conveying, and CO2 centrifugal compressors are part of the production process. In acid nitric plant, lobe blowers are used for Granulate Conveying and centrifugal compressor for nitrous gas compression.
Fans can be supplied to be gas tight and made of special materials to resist corrosion. Howden fans extract residual gas in process capacities; provide air to the process, ensure ventilation - aeration in buildings, and rooms’ pressurization. Cooling fans are used in HVAC and for refrigeration applications. Fans are selected to ensure reliable ventilation in crisis situation.
Our blowers integrate waste water treatment units. Turbo fans and blowers operate in Mechanical Vapour Recovery systems. Reciprocating compressor technologies pressurize air and nitrogen networks
Our compressors collect and transfer waste gases to flaring or treatment units.
Howden owns a set of fluid handling technologies covering ventilation, compression and heat transfer. Howden offer solutions to many specific challenges faced in fertiliser sites and processes.
Every project has different specific needs and operating conditions. Our ability to deliver custom-design solutions is extremely valuable. Whether supplied as a stand-alone unit or a complete package, our products are designed to match the rigors of its environment, and engineered to offer continuous uninterrupted operations.
Howden engineering teams and field engineers have access to our 160 years of learning, meaning we can offer our expertise at every step of the process from product selection to ongoing support. Our world organisation provide local responsive support to end users and customers.

Air regeneration
Cooling fans for Air Cooled Heat Exchanger (ACHE).
Treating contaminants such are petroleum hydrocarbons, ammonia, and organic sulfur. For mechanical system or diffused aeration system, air supply is needed into the diffuser. Howden supplies air blowers for the application.
At emergency evacuation points, axial and centrifugal provide reliable ventilation in crisis situations. Living quarters overpressure to protect rooms and staircases from hazardous fumes.
Instead of letting down high-pressure steam exhaust across a throttling valve, low-pressure waste steam can be mechanically compressed or boosted to a higher pressure so that it can be reused. Vapor recompression involves incorporating a blower to increase the temperature of the latent heat in steam to render it usable for process duties.
Air stream is introduced by a positive pressure blower upstream of material intake points.
Compression of corrosive gas. Recover off gas streams that are to be flared. Compression solutions are delivered with compatible materials and protection level according area classification.
Turbo compressors providing combustion for sulfur burning and acid regeneration.
Fan
Sulfur burning is the first step in sulfuric acid production. Compressors are used to increase the pressure of the gas going into sulfur burner.
