The invention relates to a natural gas absorbent regeneration and energy conservation technology and a natural gas absorbent regeneration and energy conservation device. The technology and the device can overcome the defects that the energy consumption is great and the heating time is long when the absorbent is regenerated. The technical scheme is as follows: a process of two towers is adopted, one tower is used for dehydration of natural gas and the other one is used for regeneration of natural gas. The two towers are switched for dehydration and regeneration of natural gas. During dehydration of natural gas, compressed natural gas first enters into the dehydration tower A to be dehydrated and obtain dried natural gas after being separated by a front filter separator, then the natural gas enters into a gas storage tank after being separated by a back filter separator; during heating and regeneration of absorbent, after flow reduction and depressurization, the regenerated natural gas is first heated in a heat exchanger and a heater and enters into the dehydration tower B to regenerate the absorbent, then, the natural gas enters into the heat exchanger to be cooled, and finally the natural gas enters into a recovery tank after being separated by a condensation separator; and during cold blowing and regeneration of the absorbent, after flow reduction and depressurization, the regenerated natural gas enters into the dehydration tower B to cold blow and reduce the temperature of the absorbent. According to the technology, complementary utilization of energy is achieved, energy consumption in absorbent regeneration is reduced, and energy-saving operation of the device is realized.

The invention provides a new concept high-speed aerocraft propulsion system layout method. Two cycles are built in a propulsion system, namely a Brayton cycle with the air as the working medium and a closed cycle with supercritical state fluid as the working medium. The two cycles are coupled through a supercritical microscopic scale heat exchange technology, a supercritical state fluid turbine and compressor power balance.
