In Shijiazhuang refinery, sewage is no longer waste, it has become a valuable resource for production. The company has invested nearly 700 million yuan in two years, using two new technologies, effective water-saving work, access to 500 million benefits; but reduced nearly 1 million tons / year of sewage discharge, received good social benefits. Site direct drainage trap Shijiazhuang refinery according to the pipe length, wide distribution, with more energy points, single point condensate trap is not focused on the actual situation, for many years to stay in the business to reduce steam leakage, regular replacement of the most primitive steam traps Management methods, in particular, a large number of high-temperature condensate direct discharge wasted, the original three sets of conventional condensate recovery station can not meet the production status, decisive investment 3.36 million to improve the steam pipe network condensate recovery system. The system uses a state-of-the-art automatic pump condensate recovery of special design, run-time does not require power, without personnel, while more, scattered around the recovery of condensate. The system was put into operation in winter 2002 and recovered about 400,000 tons of condensate in 2003. At the same time take a number of measures such as water saving, section resin, section steam, a total of more than 400 million yuan economic benefits.
