Author has introduced the problems and deficiency of tube leakage existed in low pressure reaction water cooler, tube rupture existed in waste heat boiler and the production on the low side in the summer and so on since putting into operation in the dilute nitric acid plant with a capacity of 100 kt/a by double pressurization method in the Hangzhou Longshan Chemical Engineering Company Ltd ., in allusion to this situation the technical refor-mation was made for low pressure reaction water cooler, waste heat boiler and the refrigeration dehumidification device, technical reformation result indi-cates that annual benefit is 1 112 000 Yuan RMB since having put into operation of the comprehensive project, and has a good effect.
