DEVELOPMENT OF AN AUTOMATIC REFLUX RATIO REGULATION SYSTEM FOR THE RECTIFICATION COLUMN
Bulletin of the South Ural State University. Ser. Computer Technologies, Automatic Control & Radioelectronics, 2020 This article provides an overview of the methods of managing the primary petroleum refining. To improve separation efficiency was proposed to stabilize the reflux ratio in the rectifying column. Purpose of work. To develop a system for automatic regulation of the reflux ratio of diesel fuel sec-tions in an atmospheric column of the refinery oil.

Advanced Materials, EarlyView.Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Multiple Steady States in Heterogeneous Azeotropic Distillation [PDF]
, 1994 In this article we study multiple steady states in ternary heterogeneous azeotropic distillation. We show that in the case of infinite reflux and an infinite number of trays one can construct bifurcation diagrams on physical grounds with the distillate ...

Minimum Reflux Ratio of Multicomponent Distillation for the Non-ideal System
Chemical engineering, 1967 筆者らは多成分非理想系蒸留における最小還流比について解析し, 非分配成分が存在しない場合, 理想糸で同様にピンチポイントは原料段付近にありその組成は原料の液状部分の組成に等しいことを示した。この結果, たとえ非理想系と言えども, 原料液状部分の組成に対する比揮発度を用いれば, 限界成分の与えられた分離比に対する最小遠流比は, Underwood の方法によって求めることかでき, また与えられた還流比, 留出および缶出量に対する末端組成は先に示した筆者らの方法によって求めることができる。一方, 非分配成分が現われる場合, 原料供給段とピンチボイントの間の解析的表現がえられないために, 最小還流比の計算法は煩雑になる。この場合, 逐次段計算法によって計算は可能であるが, 実用的でない。
