Abstract: 본 발명은 입체식 주차 시스템의 차량 적재 제어 방법에 관한 것으로, 종래에는 주차 설비 출입구에 차량의 중량을 제한하는 안내문을 부착하여 운전자 또는 관리자의 판단에 따라 주차여부를 결정하였다. 이에따라, 중량이 초과된 차량이 적재된 경우 과부하에 의해 주차동작에 이상이 발생되거나 기계적인 무리의 요인이 되는 문제점이 있었다. 
     이러한 점을 감안하여 본 발명에서는 차량이 적재된 리프트를 이동시킬 때 가속도가 0이면 리프트 모터용 인버터의 출력전류를 측정하여 부하 토크를 산출하고 이 부하 토크에 따라 차량의 중량을 판별하여 주차 여부를 결정하게 된다. 이에따라, 부하토크가 설정치보다 크면 제한 중량 초과 차량으로 판별하여 주차를 방지함으로써 기계적 무리를 제거함과 아울러 시스템을 안정되게 동작시킨다.

Abstract: An elemental sulfur recovery unit comprising a thermal unit configured to combust an acid gas feed comprising hydrogen sulfide, an oxygen source, and a fuel gas to create a reaction furnace outlet stream, comprising elemental sulfur, a waste heat boiler configured to capture heat from the reaction furnace outlet stream to create a waste heat boiler effluent, a condenser configured to condense the waste heat boiler effluent to produce a non-condensed gases stream and a condensed stream comprising elemental sulfur, a process gas reheater configured to generate a hot gases stream, a hydrogenation reactor configured to convert the hot gases stream to create a hydrogenation effluent comprising hydrogen sulfide, a process desuperheater configured to cool the hydrogenation effluent to generate a cooled effluent, and an absorber unit configured to absorb the hydrogen sulfide from the cooled effluent to produce a hydrogen sulfide recycle stream and a waste gas stream.
