김재강(Jae-Gang Kim),이주열(Ju-Yeol Lee),박병현(Byung-Hyun Park),최진식(Jin-Sik Choi) 한국유화학회 2015 한국응용과학기술학회지 Vol.32 No.3

The experiment was performed using the cleaning precipitator To investigate the absorption efficiency of the SOX/NOX of the aqueous ammonia solution. Concentration of the cleaning liquid is 0.1, 0.5, and 1.0% with increasing absorption efficiency has improved. However, the reaction shown only a difference in time. Absorption efficiency has improved in accordance with the gas residence time. When the direction of the same gas and the cleaning liquid is determined that there is the effect of increasing the residence time. The relative impact of SOX and NOX is this likely to react slower than SOX/NOX. The yield is determined to require adjustment of the cleaning dust collector according to the concentration of the next gas.

본 연구는 중 소형 선박의 배가스에 포함되어 있는 황산화물 및 질소산화물을 처리하기 위한 습식 스크러버의 처리효율에 관한 내용이다. 실험은 질소산화물 기술문서($NO_X$ Technical Code)의 E3 모드에 준해서 진행하였다. 엔진에서 황산화물을 배출하기 위해서, 연료로 사용되는 경유에 ditertiarybutyldusulfide를 혼합하여 황 함유량을 높인 연료로 실험을 진행하였다. 배가스 내의 질소산화물의 대부분을 차지하는 NO가스는 $NO_2$로 산화시켜 습식 스크러버로 흡수하였으며, 황산화물인 $SO_2$는 세정액에 잘 흡수되어 100% 처리효율을 확인하였다. This study deals with $de-SO_X$ and $de-NO_X$ process of a wet scrubber for small size ship engines. The experiment was conducted according to the E3 mode of the $NO_X$ technical code. In order to discharge the sulfur containing flue gas, ditertiarybutyldusulfide was added to the diesel fuel to increase the sulfur content. NO gas, which occupies most of the nitrogen oxides in the exhaust gas, was oxidized into $NO_2$ and absorbed by a wet scrubber. The developed equipment of this work achieved 100% of removal efficiency for highly soluble $SO_2$ gas in an aqueous solution.

팔라듐(Ⅱ) 이온의 존재하에서 isonitrosobenzoylacetone(IBA)과 diamine (ethylenediamine(en) 또는 trimethylenediamine(tn))으로부터 새로운 착물들인 N-(2-aminoethylisonitrosobenzoylacetone imino) chloropalladium(Ⅱ), PdCl(IBA)-en, 및 N-(3-aminopropylisonitrosobenzoylacetone imino) chloropalladium(Ⅱ), PdCl (IBA)-tn을 합성하고 이들 착물의 구조를 조사하였다. 그 결과 이들 착물은 모두 사각평면구조를 가지며 하나의 디이민리간드와 염소이온이 금속에 배위되어 있음을 알 수 있었다. 여기서 디이민리간드는 isonitrosobenzoylacetone과 diamine이 1:1로 반응하여 생성되었으며, isonitroso (=N-O), C=N 및 $NH_2$기의 세개의 질소원자들을 통하여 금속에 결합하고 있는 세자리 리간드임을 알 수 있었다. Two palladium(Ⅱ) complexes, N-(2-aminoethylisonitrosobenzoylacetone imino) chloropalladium(Ⅱ), PdCl(IBA)-en, and N-(3-aminopropylisonitrosobenzoylacetone imino) chloropalladium(Ⅱ), PdCl (IBA)-tn, have been prepared from the condensation of isonitrosobenzoylacetone (IBA) and diamine (ethylenediamine(en) or trimethylenediamine(tn)) in the presence of palladium(Ⅱ) ion. It is suggested that the Schiff base formed by condensation of an isonitrosobenzoylacetone and a diamine coordinates to the metal through three nitrogens of isonitroso (=N-O), C=N, and $NH_2$groups as a tridentate ligand. And also a chloride ion coordinates to the metal in addition to the Schiff base ligand to form a square-planar geometry.

역상 액체 크로마토그래피에 의해서Ni(IEAA-NH)(IEAA-NR)(R-H, CH₃, C₂???, n-C₃???, n-C₄????, ??????-CH₂)킬레이트의 동시 분리 및 분석을 위한 최적조건을 Micropak MCH-5 분리관을 사용하여 조사하고, 이들의 용리거동에 대한 인자들과의 관계를 검토하였다. 용리액으로 methanol/water의 이성분 용매를 사용하였으며, 모든 금속 킬레이트의 용매 세기 인자는 0≤logk'≤1의 범위임을 확인하고, 각 금속 킬레이트의 logk'값과 k'값을 도시하여 본 결과 직선 관계가 성립됨으로써 금속 킬레이트의 용리 메카니즘이 주로 소용매성 효과 즉 소수성 효과에 기인함을 확인하였다. 한편 금속 킬레이트의 머무름에 미치는 용량 인자와 온도와의 관계를 조사한 결과 좋은 직선성을 나타내고 있으며, 뿐만 아니라 직선의 기울기로부터 엔탈피(△H)와 엔트로피(△S)를 구하고, 엔탈피와 용량 인자와의 값을 도시한 결과도 직선관계가 성립하였다. 직선의 기울기로부터 구한 보정 온도(β)는 773.47。K이었다. 이 결과 역상HPLC에서 Ni(Ⅱ)-Isonitrosoethylacetoacetate imine 킬레이트의 용리 메카니즘의 주로 소수성 효과에 기인함을 재확인 할 수 있었다. Liquid Chromatographic behavior of Ni(Ⅱ)-Isonitrosoethylacetoacetate Imine(IEAA-NR), Ni(IEAA-NH)(IEAA-NR)(R=H, CH₃, C₂???, n-C₃???, n-C₄????, ??????-CH₂) chelates were investigated by reversed-phase HPLC on Micropak MCH-5 colulmn using methanol/water as mobile phase. The optimum conditions for the separation of Ni(IEAA-NH)(IEAA0NR) chelates were examined with respect to the effect of the flow rate, sample solvent, mobile phase strength and column temperature. It was found that metal chelates were properly eluted in an acceptable range of capacity factor value (0≤logk'≤1). The dependence of the logarithm of capacity factor (k') on the volume fraction of water in the binary mobile phase as well as on the liquid-liquid extraction distribution ratio (Dc) in methanol-water/n-alkane extraction system showed the good linearties, and the dependence of the logarithm of capacity factor (k') on the column temperature and on the enthalpy exhibited the good linearties, and the compensation temperature (β) from the slope was 773.47。K. It was suggested that the retention of metal chelates was largely affected by the hydrophobic effect.
