Na2CO3 - NaOH 혼합용융염과 물의 접촉에 의한 증기폭발에 관한 연구
목연수,소목회천추,상원양일 한국산업안전학회 1989 한국안전학회지 Vol.4 No.1
Molten salt-water explosion caused by the contact between molten salt and water is one of vapour explosions. An experimental study of the vapour explosion, which occurs when the molten mixture of Na₂ CO₃-NaOH and water come in contact was performed. The pressure wave generated in each composition of molten mixtures was measured. The results obtained are as follows; 1) The vapour explosian didn't occur for a molten salt of 100%- Na₂CO₃. 2) For a molten salt of Na₂CO₃80%-NaOH 20% mixture, a small vapour explosion occured initially, and a large vapour explosion, which showed the largest pressure wave among the present experiments, occurred after an induced period. 3) For molten salt of Na₂CO₃60%-NaOH 40% mixture and Na₂CO₃, 40%- NaOH-60% mixture, the vapour explosion occurred near the water surface shortly after they come incontact with water. This explosion would be caused by fragmentation of the molten salts due to impulse generated when the molten salts and water come in contact.

기포탑내에서의 n - 프로판올과 iso - 프로판올 수용액의 기체체류량에 관한 연구

n-프로판올과 iso-프로판올의 제조에서 얻어지는 숭요액을 증류할 때 각각 72%(wt)와 88%(wt)농도에서 공비혼합물을 형성한다. 따라서, 이것들을 공비증류에 의하여 효과적으로 분리하기 위해서는 이것들이 기-액 접촉을 할 때 생성되는 기체의 체류량(holdup)을 아는 것이 중요하며, 이를 위해 이들 수용액의 농도, 점도, 온도, 그리고 표면장력과 기체분산판의 형태 및 기체유속변화에 따른 기체체류량을 측정하였다. 실험결과로부터 기체체류량에 대한 수용액의 표면장력, 점도, 기체유속, 분산판의 형태 등과의 상관성을 다음과 같이 수식화하였다. Φ(δ/D ε)(μ_Lμ_G/σ_L) × 10^(10) = KR^n_(eG) When aqueous solutions obtained from the production of n-propanol and iso-propanol are distilled, azeotropes are formed at the concentrations of 72 wt% and 88 wt% respectively. So it is important to predict the gas holdup in an aqueous solution with gas-liquid contact for the effective separation by the azeotropic distillation. In this study, the gas holdup of the solution was measured at the different concentration and temperature to investigate the effect of variable physical and temperature to investigate the effect of variable physical properties such as viscosity and surface tension along with different patterns of distribution plate and different gas velocity. From the experimental result, a correlation between the gas hotdup and surface tension and viscosity of aqueous solution, gas velocity, and pattern of distribution plate was found as foltows; Φ(δ/D ε)(μ_Lμ_G/σ_L) × 10^(10) = KR^n_(eG)

We developed a JHPMA Information System to establish the voluntary safety management for the Paint Industry. IIPMA System means that manager, supervisor and worker on the process-line find out the hazardous and/or unsafe potentials, make improvement of the field safety by the cooperation with top manager, safety staff and eventually put in the practice. HI'MA Information System consists of functions to suggest and evaluate the safety concerns hierarchically from top manager to workers on mtemet or Intranet. We establish the safety management and sharing of the safety information and are able to find the unsafe potentials by the HPMA Information System. Also We are able to mine new safety information and establish accident prevention model by the Safety DATABASE.
