The solution
The efficient compressors and blowers from AERZEN – proven in numerous operating environments, suited for almost all media, unrivalled in their reliability, and adaptable to individual client specifications. Can the solution really be this easy? Yes it can! The EU directives for explosion protection play an important role in the chemical industry, among others. AERZEN always offers suitable solutions with its products. Whether in the chemical, petrochemical or energy industries, whether with ammonia, argon, styrene gas, vinyl chloride or hydrogen – oil-free compressors, blowers and vacuum pumps from AERZEN have proven themselves in over 10,000 installations and processes around the world. All blowers and compressors can be used in hazardous areas Zone 1 and in Zone 2 as defined under ATEX Directive RL 2014/34/EU as well as the Machinery Directive, including the latest safety standard (EN 1012-3).
Desulphurisation
When the spare blower in a desulphurisation plant was started there was an immediate need for a new backup machine. Big blowers (190 m³/min at 500 mbar) produce the process air for a desulphurisation plant in an oil refinery. When one blower broke down immediately the spare machine was started. As not to jeopardise the refinery process an autonomous backup was needed for the spare machine.
More machines in parallel service. To cope with the large capacity, ARD delivered four blower units in the middle of the night. The connection to the diesel generator (1000 kVA) and the air piping took place next, and before sunrise the backup machines were on standby. With T-pieces, the machines are connected to each other. Check valves in each machine prevent the air flowing away to another machine.
