Description

유증기 회수 시스템{OIL GAS RECOVERY SYSTEM}Oil vapor recovery system {OIL GAS RECOVERY SYSTEM}

본 발명은 유증기 회수 시스템에 관한 것으로서, 더욱 상세하게는 냉각시스템을 통하여 유증기를 액화하여 회수하고, 다시 유증기를 흡착 및 탈착하여 2차로 회수함과 동시에 공기중에 배출되는 VOC를 제거할 수 있는 유증기 회수 시스템에 관한 것이다. The present invention relates to an oil vapor recovery system, and more particularly, an oil vapor recovery capable of liquefying and recovering the oil vapor through a cooling system, and secondly recovering the oil vapor by adsorption and desorption and at the same time removing VOCs discharged from the air. It's about the system.

일반적으로 주유소 또는 유류를 다량 사용하는 공장 등에는 유조차량 등으로부터 유류를 공급받는 유류저장탱크 가 마련되어 있다. 유류저장탱크에 저장된 유류는 휘발성이 강하여 자연적으로 증발하여 상당한 양의 유증기가 발생한다. 발생된 유증기는 유류저장탱크에 설치된 배기관을 통해 외부로 배출된다.In general, gas stations or factories that use large amounts of oil have oil storage tanks that receive oil from tankers. The oil stored in the oil storage tank is highly volatile and naturally evaporates to generate a considerable amount of oil vapor. The generated oil vapor is discharged to the outside through an exhaust pipe installed in the oil storage tank.

배기관을 통해 배출되는 유증기는 휘발성 유기화합물이다. 휘발성 유기화합물(Volatile Organic Compounds: VOCs)은 증기압이 높아 대기 중으로 쉽게 증발되는 액체 또는 기체 상 유기화합물을 말하는데, 대기 중에서 햇빛의 작용으로 인해 질소산화물과 광화학반응을 일으켜 오존 및 팬(PAN: 퍼옥시아세틸 나이트레이트)등의 광화학 산화성 물질을 생성시킴으로써 광화학 스모그를 유발하는 대기오염물질이며, 발암성을 가진 독성 화학물질로서 광화학 산화물의 전구물질이기도 하다. The oil vapor discharged through the exhaust pipe is a volatile organic compound. Volatile Organic Compounds (VOCs) refer to liquid or gaseous organic compounds that are easily evaporated into the atmosphere due to their high vapor pressure. It is an air pollutant that causes photochemical smog by producing photochemical oxidizing substances such as acetyl nitrate), and is a toxic chemical substance with carcinogenicity and is a precursor of photochemical oxides.

또한 지구온난화와 성층권 오존층 파괴의 원인물질이며, 악취를 일으키기도 한다. 현재 세계적으로 휘발성 유기화합물의 배출을 규제하는 국가가 증가하는 추세에 있으며, 국내에서도 저유소, 주유소, 세탁시설과 같은 규제대상시설에서는 배출억제 및 방지시설 설치를 의무화하고 있다.It is also a causative agent of global warming and the destruction of the stratospheric ozone layer, and it also causes odor. Currently, countries that regulate the emission of volatile organic compounds are on the rise in the world, and it is mandatory to install emission control and prevention facilities in regulated facilities such as storage stations, gas stations, and laundry facilities in Korea.

대한민국 공개특허 제 2014-0070123호에는 유류저장탱크의 유류 휘발 억제장치가 개시되어 있다. 상기 특허는 지하공기를 이용하여 유류저장탱크를 냉각시켜 유류의 휘발을 억제시킨다. 유류저장탱크에서 자연적으로 발생하는 유증기는 서서히 조금씩 발생하여 외부로 미량 배출되므로 상기 특허와 같이 지하공기만을 이용하더라도 유증기의 배출을 억제하는 효과가 있다.Republic of Korea Patent Publication No. 2014-0070123 discloses an oil volatilization suppression device of an oil storage tank. The above patent suppresses volatilization of oil by cooling an oil storage tank using underground air. Since the oil vapor naturally occurring in the oil storage tank is gradually generated little by little and a trace amount is discharged to the outside, there is an effect of suppressing the discharge of oil vapor even if only underground air is used as in the above patent.

하지만, 유류저장탱크에 유류를 보충할 때, 예컨대 유조차량에서 유류를 유류저장탱크 내로 공급할 때는 공급되는 유류의 부피만큼 탱크 내부에 존재하고 있는 다량의 유증기가 일시에 외부로 배출되는 문제점이 있다.However, when replenishing oil to the oil storage tank, for example, when supplying oil from the tanker into the oil storage tank, there is a problem in that a large amount of oil vapor existing in the tank as much as the volume of the supplied oil is discharged to the outside at once.

상기 유류저장탱크에 유류 주입이 완료된 후 소정 시간이 경과한 후에는, 상기 진공펌프를 역구동시켜, 상기 유증기냉각부의 응축열을 상기 진공펌프를 통해 상기 진공흡착부에 공급하고 상기 유증기냉각부의 고온의 응축열을 이용하여, 상기 진공흡착부의 다공성 흡착제에 흡착된 물질을 탈착시키고, 상기 진공흡착부로부터 상기 유증기냉각부로 유증기가 공급된 후, 상기 유류회수부로 회수되는 것을 특징으로 하는 유증기 회수 시스템.



The method according to claim 1 or 2,
When gasoline is injected into the oil storage tank, oil vapor is supplied from the oil storage tank to the oil vapor cooling unit, and the oil vapor remaining without being cooled in the oil vapor cooling unit is supplied to the vacuum suction unit and is adsorbed and desorbed from the vacuum suction unit. The oil vapor is recovered secondarily,
After a predetermined period of time has elapsed after the oil injection to the oil storage tank is completed, the vacuum pump is driven in reverse to supply the heat of condensation of the oil vapor cooling unit to the vacuum adsorption unit through the vacuum pump, and the high temperature of the oil vapor cooling unit is Using the heat of condensation, the material adsorbed on the porous adsorbent of the vacuum adsorption unit is desorbed, and after the oil vapor is supplied from the vacuum adsorption unit to the oil vapor cooling unit, it is recovered to the oil recovery unit.
