GEA's nozzle needle-controlled vapor jet compressor enables the specific steam consumption for the thermal separation technology to be reduced by up to ten percent. For Olin, the reduction in specific steam consumption as well as the entire, overall system for thermal separation technology has a positive effect on operating costs.
Size of jet pump and large control range had to be taken into account in project planning
The overall system was developed by GEA in close coordination with Olin and all the requirements defined in advance by the customer. In addition to the size of the jet pump (DN 800), the large control range was a challenge in planning the project. The choice fell on a system with a nozzle needle-controlled steam jet compressor. These are used for tasks that require a wide load range. Their advantage over control by a throttle valve is the constant high motive steam pressure. In this case, the adjustment to the required energy takes place exclusively via the control of the motive steam quantity. The loss of power that occurs with throttling is eliminated. This enables savings of up to ten percent in steam consumption.
Wide range of applications for nozzle needle-controlled steam jet compressors from GEA
In principle, nozzle needle-controlled steam jet compressors from GEA can be used wherever excess waste heat can be compressed to a higher pressure level for further use as process energy.
