The Puguang natural gas purification plant of SINOPEC Zhongyuan Oilfield has been in operation for more than 14 years.The original thermal insulation design of the steam pipeline is used by aluminum silicate cotton.When the ambient temperature drops suddenly,such as extreme cold or rainstorm,heat loss of the thermal insulation facilities is larger,which is easy to cause quality decline of the regeneration steam,affecting the regeneration effect of a-mine solution,and there is an increased risk of sulfur dioxide emissions from flue gas.Through the research on high efficiency thermal insulation technologies for steam systems and the optimi-zation of insulation materials and structures,the new composite insulation materials can reduce steam heat loss by about 61％,and a single unit can save over 410000 yuan in annual expenses.
