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.
