Through the design and manufacture of oxidizers and dryers, we had been continuing to seek the ideas, how to operate the dryer safely and how to keep energy saving.
\r\nOn the other hand, it became another matter that the investment cost of oxidizer was getting up higher, because of increase of exhaust gas volume to be treated by oxidizer.
\r\nTo solve the matter, we started our project to develop the new system intending to \u201chow to reduce the volume of exhaust gas from dryer, in other words, how to increase the recycling rate of hot air for dryer safely and how to increase the solvent concentration in exhaust gas in a safety range\u201d.
\r\nIn this project, based on optical interferometic method gas analyzer by RIKEN KEIKI Co., Ltd., we succeed to develop the new system called “TGCS:TED Gas Control System” that analyze the solvent concentration in the dryer continuously and control the flow rate of exhaust gas automatically so that to meet to the preset solvent concentration rate of exhaust gas.
\r\nBy combining TGCS and the oxidizer, we succeed in reducing of exhaust gas volume and designing for energy saving system, which came to the result of big cost saving for the investment of oxidizer and its incidental facilities.<\/div>\r\n<\/div>\r\n
