Description

에틸렌글리콜 잔사(殘渣)를 이용한 고로용 연료의 제조방법{Method for manufacturing of fuel for blast furnace using ethylene glycol residue}Method for manufacturing of fuel for blast furnace using ethylene glycol residue}

본 발명은 에틸렌글리콜(EG)잔사(殘渣)[이하"EG잔사"라 칭함]를 이용한 고로용 연료의 제조방법에 관한 것으로, 더욱 구체적으로는 폴리에스테르(Polyester)원료제조시에 (TPA+EG반응으로 생긴 중간생성물)필히 발생되는 폐기물인 EG잔사를 고열의 에너지를 필요로 하는 고로 대체에너지로 사용이 가능한 고로용 연료의 제조방법을 제공하는 것이다.The present invention relates to a method for producing a blast furnace fuel using ethylene glycol (EG) residue (hereinafter referred to as "EG residue"), more specifically (TPA + EG in the production of polyester raw material) It is to provide a method for producing a blast furnace fuel that can be used as an alternative energy for blast furnaces that require high heat energy.

폴리에스테르(Polyester)는 다가알콜과 다염기산의 축합으로 이루어지는 고분자 화합물로서 내약품성 내열성이 뛰어나 가구, 건재, 합성섬유, 약품 및 음용수 용기등에 이용되고 있으며, 폴리에스테르계 합성섬유는 에틸렌글리콜(EG)과 테레프탈산(TPA)으로 구성된다.Polyester is a polymer compound composed of condensation of polyhydric alcohol and polybasic acid. It has excellent chemical resistance and is used in furniture, building materials, synthetic fibers, chemicals and drinking water containers. Polyester-based synthetic fibers include ethylene glycol (EG) and It consists of terephthalic acid (TPA).

EG잔사는 이러한 폴리에스테르의 원료 제조시에 TPA+EG반응으로 생긴 중간생성물로서 발생하는 폐기물로서 발생된 량의 극소수는 폐인트제조첨가물 또는 다시 반응시켜 저급품 원료로 사용하고 있으나 그량은 극소수이다.The EG residue is a waste produced as an intermediate product produced by the TPA + EG reaction in the manufacture of the raw material of polyester, and is used as a low grade raw material by using a waste ste additive or reacting again.

즉 EG잔사는 폴리에스테르(Polyester)미숙성체이며 폴리에스테르90%, 에틸렌글리콜약10%가 함유된 열경화성 플라스틱에 속하는 고분자 화합물로서 현재 많은 량의 EG잔사(월간수백톤이상)가 발생하고 있는데 거의 전부 폐기물로 처리되고 있을 뿐만 아니라 그 처리비용도 많이 들게 되고 EG잔사를 소각하여 처리하므로 공기오염을 발생시키는 등 문제점이 있었다.In other words, EG residue is a polyester immature and is a high-molecular compound belonging to thermosetting plastic containing 90% of polyester and about 10% of ethylene glycol. Currently, a large amount of EG residue (more than several hundred tons per month) is generated. In addition to being treated as waste, the treatment costs are also high, and there is a problem such as generating air pollution since the EG residue is incinerated.

본 발명은 이러한 문제점을 해결하기 위하여 폴리에스테르 원료제조시에 발생되는 에틸렌글리콜(EG)잔사를 코크스분탄이나 폐플라스틱 또는 유기성폐기물과 혼합하여 고로의 대체연료로 제공할수 있도록 한 것이다.In order to solve this problem, the present invention is to provide the ethylene glycol (EG) residue generated during the manufacture of polyester raw materials as coke pulverized coal, waste plastic or organic waste as a substitute for blast furnace.

본 발명의 에틸렌글리콜(EG)잔사(殘渣) 폴리에스테르(Polyester)미숙성체로서 폴리에스테르원료제조시에 테레프탈산(TPA)+에틸렌글리콜(EG)반응으로 생긴 중간생성물이며 폴리에스테르90%, 에틸렌글리콜 약10%가 함유되어 있다.The ethylene glycol (EG) residue of the present invention is an immature polyester and is an intermediate product produced by terephthalic acid (TPA) + ethylene glycol (EG) reaction in the production of polyester raw material, 90% polyester, about ethylene glycol Contains 10%

이러한 상기 EG잔사를 80∼150℃로 가열용융하여 겔(gel)상태로 만들고 여기에 입도10mm이하의 코크스분탄이나 폐플라스틱 또는 유기성폐기물을 15 : 85 내지 95 : 5 중량%로 혼합하여 그 혼합물을 5내지 300mm의 입도를 갖는 괴상의 성형체를 제조하는 공정의 고로용 연료제조방법이다.The EG residue is heated and melted at 80 to 150 ° C. to a gel state, and coke pulverized coal, waste plastic or organic waste having a particle size of 10 mm or less is mixed at 15: 85 to 95: 5% by weight to the mixture. It is a blast furnace fuel manufacturing method of the process of manufacturing the block-shaped molded object which has a particle size of 5 to 300 mm.

즉, EG잔사를 이용하여 제철소, 시멘트공장등 고로사용의 공장에서 쓰이는화석연료의 대체연료로서 사용가능하도록 하는 방법으로서 고로의 연료로 사용되는 EG잔사를 코크스분탄이나 폐플라스틱 또는 유기성폐기물을 결합시키는 결합제(binder)역할뿐만 아니라 EG잔사 자체가 고로의 연료 및 환원제의 역할을 할수도 있다.In other words, the EG residue is used as an alternative fuel for fossil fuels used in blast furnaces such as steel mills and cement factories. The EG residue used as blast furnace fuel is combined with coke pulverized coal, waste plastic or organic waste. In addition to being a binder, the EG residue itself can also serve as a fuel and reducing agent in the blast furnace.

그리고 EG잔사와 혼합되는 코크스 분탄은 고로의 연료로 사용하면 투입공정에서 고로에서 발생되는 가스의 상승기류로 인해 연료로 사용되기 전에 고로밖으로 배출될수 있어서 고로의 연료로 사용되지 못하는 10mm이하의 입도를 갖는 코크스분탄은 모두 사용할수 있으며, 특별한 전처리공정을 실시할 필요없다.And coke pulverized coal mixed with EG residue can be discharged out of the blast furnace before being used as fuel due to the rising air of gas generated in the blast furnace in the input process. All coke pulverized coals can be used, and no special pretreatment step is required.

상기 폐플라스틱은 필름상 및 고형상, 분말등 모두 활용 가능하며 성분에 있어서 단일 물질이 아닌 혼합폐플라스틱을 사용하여도 무방하다The waste plastic can be used both in film form, solid form, powder, etc., and it is also possible to use mixed waste plastic instead of a single substance in the composition.

특히 토양이나 기타 유,무기성 이물질이 어느정도 혼입되어 있어도 전처리없이 사용할수 있다.In particular, it can be used without pretreatment even if soil or other organic and inorganic foreign substances are mixed to some extent.

상기 유기성 폐기물은 폐고무, 제지슬러지, 폐수슬러지, 하수슬러지, 폐목분으로 어느 1종만을 선택하여 사용하거나 2종이상 포함시켜 사용한다.The organic waste is selected from the group consisting of waste rubber, paper sludge, wastewater sludge, sewage sludge, and waste wood powder.

본 발명에서 사용하는 EG잔사는 코크스분탄이나 폐플라스틱 또는 유기성 폐기물과의 혼합비는 원하는 성형체의 물성 및 원료물질의 종류에 따라 다르게 되나, 보통 중량기준으로 EG잔사는 15내지 95중량%와, 코크스분탄이나 폐플라스틱 또는 유기성폐기물은 5내지 85 중량%를 혼합한다 여기서 EG잔사의 사용량은 최소 15중량% 이상이어야 하며 15중량% 미만인 경우에는 EG잔사에 의해 제공되는 결합체 역할이 불충분하여 괴상의 성형체 제조가 어려워 바람직하지 않고, EG잔사의 사용량이 95중량%를 초과하는 경우에는 고로의 연료로 사용하기 위한 발열성이 약화되어 바람직하지 않다.The EG residue used in the present invention is different from the mixing ratio of coke pulverized coal or waste plastic or organic waste depending on the physical properties of the desired molded article and the type of raw materials, but the EG residue is usually 15 to 95% by weight and coke pulverized coal. However, waste plastic or organic waste is mixed in an amount of 5 to 85% by weight. Here, the amount of EG residue used should be at least 15% by weight or more. It is difficult and undesirable, and when the amount of the EG residue exceeds 95% by weight, the exotherm for use as blast furnace fuel is weakened, which is not preferable.

성형체의 입도는 5내지 300mm로 하되 바람직하기로는 고로형태에 따라 코렉스고로에서의 성형체 입도는 10∼60mm, 일반고로에서의 성형체 입도는 5∼8mm, 시멘트고로에서의 성형체 입도는200∼300mm로 제조하여 사용한다.The particle size of the molded body is 5 to 300mm, preferably according to the shape of the blast furnace, the particle size of the cortex blast furnace is 10-60mm, the particle size of the blast furnace is 5-8mm, and the particle size of the cement blast furnace is 200-300mm. Use it.

본 발명에 따른 고로의 대체연료로 이용되는 EG잔사와 여기에 혼합되는 코크스분탄, 폐플라스틱, 유기성폐기물의 발열량은 다음과 같다.The EG residue used as an alternative fuel of the blast furnace according to the present invention and the calorific value of coke pulverized coal, waste plastic, and organic waste mixed therein are as follows.

상기의 EG잔사와 이와 혼합되어 고로용 연료로 제조하기 위한 배합실시예는 다음과 같다.The mixing example for producing the EG residue and the blast furnace fuel mixed with the above is as follows.

* 상기에서 유기성폐기물은 폐고무, 제지슬러지, 폐수슬러지, 하수슬러지, 폐목분에서 선택되는 1종 또는 2종이상 사용한다.* The organic waste is used one or two or more selected from waste rubber, paper sludge, wastewater sludge, sewage sludge and waste wood powder.

EG잔사와 여기에 혼합되는 코크스분탄, 폐플라스틱, 유기성폐기물로 괴상의 성형체를 제조하게 되는데 종래의 고로연료로 사용되던 괴상코크스 및 괴상석탄과 비슷하거나 더큰 발열량을 얻고자 할때에는 EG잔사에 높은 발열량을 가진 코크스분탄, 폐플라스틱, 폐고무를 혼합한 성형체를 제조하며, 비교적 낮은 발열량의 연료를 얻고자 할때에는 EG잔사에 발열량이 낮은 제지슬러지, 폐수슬러지, 하수슬러지, 폐목분을 혼합한 성형체를 제조한다.The EG residue is mixed with coke pulverized coal, waste plastic, and organic waste, which is used to produce a bulk molded product.The high calorific value of EG residue is obtained when the calorific value is similar to or larger than that of the conventional blast furnace fuel. Coke pulverized coal, waste plastic, and waste rubber are manufactured. To obtain fuel with relatively low calorific value, EG residue is made of paper sludge, wastewater sludge, sewage sludge, waste wood powder. Manufacture.

이렇게 EG잔사를 이용하여 고로용 대체연료로 만들어진 괴상의 성형체를 고로에서 1200∼2000℃의 고열로 완전연소시키므로 공해발생을 최소화 시킬수 있게 된다.In this way, the EG residue is used to completely burn the molded body made of alternative fuel for blast furnace at high temperature of 1200 ~ 2000 ℃ in the blast furnace, thus minimizing pollution occurrence.

이와같이 된 본 발명은 폴리에스테르 제조공정에서 발생되는 폐기물로 처리되는 EG잔사를 이용하여 고로의 대체연료로 사용이 가능하고 또한 폐기처리되던 코크스분탄, 폐플라스틱 유기성폐기물과 혼합하여 사용되므로 경제적이고 환경오염 도 줄일수 있는 매우 유용한 효과가 있다.Thus, the present invention is economical and environmental pollution because it can be used as alternative fuel of blast furnace by using EG residue treated as waste generated in polyester manufacturing process and also mixed with waste coke pulverized coal and waste plastic organic waste. There is also a very useful effect that can be reduced.
