| titleOfInvention | Heat exchanger cleaning method and polyester manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing stable quality polyester and a heat exchanger cleaning method for achieving the method. In a process for producing a polyester by using 1,4-butanediol as a component and performing a polycondensation reaction in a molten state at a pressure of 10 kPa or less using a polymerization catalyst. A method for cleaning a condenser or a heat exchanger, wherein the condenser for condensing the condensed gas or the heat exchanger for cooling the condensed liquid of the distilled gas is washed at 50 to 300 ° C.
