Low energy-consumption blankholding is a new variable blankholding force controlling method of low energy-consumption.

Furthermore the features of the upturning situation in gas industry are as follows:development and operation of small air separation plants with low pressure and low consumption;emerging central oxygen supply in region ;seeking for coordinate dev.

A waste water treatment technology of low energy consumption;

A batch cooking technology with low energy consumption——DDS~(TM) substitution cooking system;

Effect of propionic to acetic acid ratio on biological nitrogen and phosphorus removal with low energy consumption;

Natural ventilation in low energy architecture design;

It is introduced the design of air conditioning and ventilation system for the low energy library of Nanjing Institute of Technology.

Laboratory research,industrial production and field application of the resultant HBC concrete demonstrate that HBC is a kind of low energy consumption and low CO2 emission Portland cement with low hydration heat evolution,high later age strength and high performance,compared with normal PC.
