At present, I am looking for a steam compressor or steam compressor system that can compress very low pressure steam (2.56 kPa) to 1 bar and above. I know well that such high compression ratio will be impossible for a single set to achieve, therefore it more than one sets have to set in series that's welcome too. To be precise, I am looking for steam compressor system(s) that can compress steam as said above. Such sets were and still are used in open cycle and/or hybrid OTEC plants. If anybody can refer a company that can manufacture such sets, I will be grateful to him/her.
