Abstract
The invention relates to a flashed vapor regenerating system which is used for regenerating purificant in a natural gas purifying system. The purifying system comprises a natural gas inlet pipeline, a natural gas outlet pipeline, a regenerative gas inlet pipeline and a regenerative gas outlet pipeline; natural gas enters the purifying system to be purified through the natural gas inlet pipeline and then is discharged through the natural gas outlet pipeline; the flashed vapor regenerating system comprises a storage tank and a heat exchange device; the storage tank is provided with a liquid inlet and a flashed vapor outlet; the natural gas outlet pipeline is connected with the liquid inlet of the storage tank through the heat exchange device; and the flashed vapor outlet of the storage tank is connected with the regenerative gas inlet pipeline. As the flashed vapor regeneration system adopts flashed vapor as regenerative gas in the purifying system, other mediums can be prevented from being introduced during the purification of natural gas, and flashed vapor can be sufficiently utilized and prevented from being lost during purification and generation processes.
Description
Technical field
The present invention relates to a kind of flashed vapour regenerative system and technology of in gas purifying process, using.
Background technology
In the existing gas purifying process, during the objectionable impurities in removing natural gas (water, benzene, heavy hydrocarbon, carbon dioxide and mercury), old process is third party's medium of adopting chemical method to absorb to combine with the steam parsing (like nitrogen etc.) thermal regeneration.This purification style can be introduced other medium, and can loss part flashed vapour in the regenerative process.
Summary of the invention
The purpose of this invention is to provide a kind of flashed vapour regenerative system and technology of not introducing other medium and making full use of natural gas.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of flashed vapour regenerative system; The cleanser of described cleaning system is used for regenerating in the natural gas purification system; Described cleaning system has natural gas air inlet pipeline, natural gas outlet pipe, regeneration gas air inlet pipeline, regeneration gas outlet pipe; Natural gas is got in the described cleaning system by described natural gas air inlet pipeline and purifies; Discharge via described natural gas outlet pipe, described flashed vapour regenerative system comprises storage tank, heat-exchanger rig again, and described storage tank has inlet and flashed vapour outlet; Described natural gas outlet pipe is connected with the inlet of described storage tank through described heat-exchanger rig, and the flashed vapour outlet of described storage tank is connected with described regeneration gas air inlet pipeline.
