MVR의 경우 압축과정을 폴리트릭픽과정으로 가정하여 이론적 모델링을 수행하였고, 그 성능은 제작사에서 제공된 성능곡선을 사용하여 평가하였다. TVR의 해석 및 설계에 있어서는 노즐과 디퓨저를 포함한 내부에 유체유동에 대한 보존방정식을 적용하여 분석하였다. 이를 통해 노즐과 목, 그리고 디퓨저의 크기를 결정할 수 있었다. MVR와 TVR의 이론적 모델링은 3개회사의 설계자료와 그 성능 및 에너지 및 질량수지를 비교하여 검증하였고, 본 모델의 실용적 적용을 위해 GUI 설계 툴을 개발하였다. 본 툴을 활용해 MVR과 TVR의 물질 및 에너지수지와 이들의 세부 설계규격을 결정할 수 있다. The MVR was theoretically modeled by assuming the process as the polytropic process, and the performance of the MVR was estimated by using the performance-curve provided by the manufactures. The TVR was investigated by applying the conservation equations to the movement of the fluids inside the TVR. The size of the nozzle and diffuser can be determined. The theoretical MVR and TVR modeling was verified by comparing the results from the model with the available design data. Besides, the GUI program was developed for the practical usage of the modeling. The mass and energy balance information, and the specifications for the MVR and TVR can be available by using the GUI tool.

The theoretical modelling for designing of the MVR(mechanical vapor recompression) and the TVR(thermal vapor recompression) in the chemical process has been conducted in the present study. The steam compressing process in the MVR is modelled as the polytropic process, and the other losses for the bearing, sealing, and gear parts are all considered in calculating the actual power consumption. The designing of the nozzle in the steam jet ejector for the TVR is carried out by applying the model, which was developed through the conservation laws of mass and energy. The sizes of the ejector is determined by the semi-empirical models. This model is applied to design the actual sized MVR and the TVR in the chemical process.
