Title: Thermal decomposition of dichloroethane
Inventor: MURATA YOSHIFUMI
IPC: C07C67/00
Filed: 1986-12-22
Abstract: PURPOSE:To remarkably promote thermal decomposition, by using a specific amount of hexachlorocyclopentadiene as a decomposition accelerator in thermally decomposing 1,2-dichloroethane into vinyl chloride. CONSTITUTION:1,2-Dichloroethane is thermally decomposed at 300-600 deg.C, preferably 400-550 deg.C to afford vinyl chloride. In the process, hexachlorocyclopentadiene in an amount of 0.001-1wt%, preferably 0.005-0.2wt% based on the raw material is used as a decomposition accelerator. Since the contact time can be shortened by the above-mentioned method and the reaction temperature can be reduced by even 50-100 deg.C if the decomposition ratio is kept at the same level, limitation on equipment materials can be relaxed and operating efficiency of the equipment can be increased because of remarkably reduced deposition of carbonaceous substances. Furthermore, since small amounts of additives are sufficient, there is hardly any fear of contaminating products.

Title: Method and device for detecting contaminant on contact heat transfer surface in combustion furnace
Inventor: NAKAJIMA KUNIHIKO
IPC: F22B37/42
Filed: 1991-10-24
Abstract: PURPOSE:To accurately detect the presence of contaminant on the contact heat-transfer surface of a combustion furnace. CONSTITUTION:A combustion amount of a combustion furnace 2 is detected and simultaneously a pressure in the combustion furnace 2 is detected. A proper pressure in a furnace corresponding to a detected combustion amount or the upper limit pressure value thereof is compared with a pressure in a combustion furnace. When the pressure in a combustion furnace exceeds the proper pressure in a furnace, it is decided that a contaminant is present on the surface of a heat-transfer pipe group 20. In this way, a contaminant on the surface of the heat-transfer pipe group 20 which is arranged in a flue 2A and through which fluid 3p to be heated is caused to flow can be detected regardless of a contaminant produced owing to combustion gas even when the contaminant owing to combustion gas in the combustion furnace 2 is deposited to same part of a contaminant detecting device 41. By cleaning the heat-transfer pipe group 20 at a proper time according to a detected result, heat-exchange operation at the heat-transfer pipe group 20 is maintained in an excellent state and energy is saved.
