Abstract
The utility model discloses a glycol regenerating device, belonging to an ordinary instrument in organic chemistry. The glycol regenerating device comprises a three-phase separator, a rectifying column, a heating tank, a buffer tank and a flash tank, wherein a raw material inlet a is connected with the three-phase separator through a pipeline; a natural gas outlet b is formed on the top of the three-phase separator; a liquid hydrocarbon outlet c is formed at the middle part of the three-phase separator; a glycol-enriched liquid outlet pipeline d is arranged at the bottom of the three-phase separator and enters a pipe passage of the rectifying column; an outlet e of the rectifying column enters a pipe passage of the buffer tank; an outlet f of the buffer tank enters the flash tank; the top outlet g of the flash tank is connected with a flambeau vent; and a lower outlet h of the flash tank returns to the rectifying column. The glycol regenerating device is good in glycol regenerating effect, uniform in injection and effective in inhibition of formation of natural gas hydrate; through multi-stage heat exchange, the heat loss is low and the running cost is low; the glycol regenerating device is equipped with an advanced heater and an advanced control system, so that the glycol regenerating device runs stably and is high in heat efficiency, safe and reliable; and by a prying technology, the glycol regenerating device is compact in structure, is an independent system and is quick to install, convenient to carry and move, simple in process and convenient to operate.
Description
Technical field
The utility model belongs to vitochemical general instrument, particularly ethylene glycol regenerating device.
Background technology
At present, utilize ethylene glycol to carry out the theoretical maturation of gas production dewatering process, be widely adopted in the at home gas field development process.Used ethylene glycol need to dewater to regenerate and could continue to use.Ethylene glycol regenerating device is in practical process in recent years, some problems have been exposed, as: can not accurately control the liquid level of regenerator reboiler well, heat exchange efficiency is low, and the regenerator treating capacity is little, and the ethylene glycol primary recycling is qualified poor, the loss of ethylene glycol is more, in addition, device, pipeline corrosion is serious, and the regenerative system operation is stable not.Also usually blocking pipe and equipment because generate hyrate in gas extraction, conveying and processing.
Summary of the invention
In order to address the above problem, the utility model is intended to make a kind of compact conformation, has autonomous system of one's own, and is quick for installation, is convenient to resettlement, flow process brief introduction, easy to operate ethylene glycol regenerating device.
Ethylene glycol regenerating device of the present utility model is to be made of three phase separator, rectifying column, heating tank, surge tank and flash tank.Feed(raw material)inlet a pipeline is connected to three phase separator, the outlet f that the outlet e that the top of three phase separator has gas outlet b, middle part to have liquid hydrocarbon outlet c, bottom to have glycol rich solution export pipeline d to enter tube side, the rectifying column of rectifying column enters the tube side of surge tank, surge tank enters flash tank, the top exit g of flash tank connects torch emptying, and lower outlet h returns in the rectifying column.The top of rectifying column is that steam outlet, bottom enter the surge tank shell side through heating tank, and the bottom of surge tank shell side is that glycol lean solution outlet i returns to the pipeline of feed(raw material)inlet a.
As further improvement of the utility model, described rectifying column base is on heating tank, and the heating fangs is on surge tank, and its shell side is connected.
As further improvement of the utility model, the outlet i place of the outlet h of flash tank and surge tank is equipped with filter.
Ethylene glycol regenerating device reasonable in design of the present utility model, in natural gas, inject quantitative ethylene glycol inhibitor and avoid the formation of hydrate, be re-introduced in the natural gas after with the glycol recycling concentrate by heating means and recycle carrying terminal point ethylene glycol to be separated and entered ethylene glycol regenerating device.Glycol recycling is effective like this, injects evenly the formation of establishment gas hydrates; Adopt multi-stage heat exchanger, thermal losses is low, and operating cost is low; Advanced heater and the control system of device configuration, stable thermal efficiency height is safe and reliable; Use the skid micronizing technology, apparatus structure is compact, has autonomous system of one's own, and is quick for installation, is convenient to resettlement, and flow process is simple and direct, and is easy to operate.
