초록
본 연구에서는 국내 석유화학공장에서 운전되고 있는 CDU plant heater, NCC plant heater, CO plant Heater, aromatic plant heater 등 15개 plant heater를 대상으로 조사하였으며, 세부 내용으로는 heater 사고 예방을 위한 공정운전 표준, alarm 작동시 조치 및 setting 변경, 시운전 점검사항, interlock system 분석, interlock by-pass 운전현황, heater 주요 사고
In this paper it was investigated 15 heaters of CDU plant heater, NCC plant heater, CO plant heater, Aromatic plant heater and so on while running in our country. It was also analysed the standard of operation procedure, the action in alarm, the interlock system, the operating situation of the interlock by-pass and major accident about the heater and so on. This paper presents the installation of the on-line monitoring, the additional installation of the local pressure gauge and temperature gauge, the check in starting operation,'the management of the interlock by-pass, the change of manufacturer causing the disorder of instrument sensor, the management method of DCS alarm for methods of the interlock prevention and facilities improvement. It was few information about the heater interlock in the inside and outside of the country We mainly have studied with reflecting the opinion of the operator and manager on site, the sheet of process trouble and operation procedure and so on. we think that the accident relating to the interlock will significantly reduce if the companies apply the conclusion of this study(i.e. methods of the interlock prevention and facilities improvement).
