Title: Production of ethane dichloride
Inventor: WACHI TAKASHI
IPC: C07C17/08
Filed: 1985-05-22
Abstract: PURPOSE:To recover latent heat and utilize effectively the heat, by introducing a reaction medium vapor into a heat exchanger connected to the upper part of a reactor, and condensing the vapor in reacting ethylene with chlorine to give ethane dichloride useful as a raw material for vinyl chloride monomer. CONSTITUTION:Ethylene and chlorine are fed to a liquid reaction medium consisting essentially of ethane dichloride and reacted at >= the boiling point of the ethane dichloride under normal pressure, i.e. <=83 deg.C, particularly 100-160 deg.C to produce the aimed ethane dichloride and generate the reaction medium vapor from the upper part (B) of the reactor. The resultant vapor is then led to a heat exchanger (C) to recover and utilize the latent heat due to the condensation and liquefaction of the vapor in the heat exchanger (C). The recovered heat is preferably used as a heat source for a reboiler of a distillation column for purifying the ethane dichloride.

Title: Condensed heat transmission surface and its manufacturing
Inventor: FUJII MASAO
IPC: F28F13/00
Filed: 1978-09-08
Abstract: PURPOSE: To enhance heat transmission efficiency by providing needle form protrusion on the surface of heat transmission base plate which makes liquid film thin.  
     CONSTITUTION: Needle form protrusion 2 is established on the surface of heat transmission base plate 1. Liquid film 4 is formed when high temp. vapor contacts  the heat transmission surface 3 having the above mentioned protrusion 2. At this  time, thickness of liquid film 4 is made thinner in the vicinity of the tip 5 of the  needle protrusion, making heat transmission rate α larger. At the heat transmission  surface 3 where its protrusion 2 points downward, droplet 6 of liquid is generated  at the protrusion tip when high temp. vapor condenses, and drops down. This  means that excess amount of liquid is removed from the surface 3, making liquid  film 4 thinner in thickness and heat transmission rate α is enhanced.
