Description
Technical field
The utility model relates to fld production gas technology field, and particularly a kind of Sweet natural gas carries out dehydrated device, is a kind of tower tray whirlwind-type pre-separation dehydration absorption tower.
Background technology
At present, in the stratum, in the Sweet natural gas and the purified natural gas after the desulfurization of extraction, generally all contain the steam of saturation capacity, steam is component pernicious in the Sweet natural gas.The existence of steam in the Sweet natural gas has reduced the transport capacity of gas pipe line to other active principle, has reduced the calorific value of Sweet natural gas.And, when distribution pressure and variation of ambient temperature, possibly cause that steam separates out from Sweet natural gas; Form the solid hydrate of liquid water, ice or Sweet natural gas; The existence of these materials can increase the gas transmission pressure drop, reduces the handling capacity of gas transmission line, reduces the handling capacity of gas transmission line; Also can stop up valve and pipeline when serious, influence steady air feed.When conveying contained the acidic components Sweet natural gas, the existence of liquid water also can be quickened the corrosion of acidic components to tube wall, valve, reduced the pipeline life-span.Therefore, Sweet natural gas must carry out processed, reach regulation contain the water dew point index after, just allow to get into the gas transmission main line.
At present, the oil field extensively adopts triglycol that Sweet natural gas is dewatered.Traditional triglycol dehydration is main further deviates from the moisture in the Sweet natural gas utilizing the adsorption of triglycol, makes it to reach outer defeated dew point requirement.Traditional process: come gas through double-drum filter, triglycol absorption tower and outside defeated three stages.Liquid content fluctuates bigger in the gas owing to coming; Double-drum filter is effective separated free water often; Separated structures once more is not set in the absorption tower in addition; Thereby cause the water dew point in the Sweet natural gas after triglycol absorbs not reach outer defeated requirement, the part triglycol is brought into piping system by gas, causes triglycol loss.
The utility model content
The purpose of the utility model is: a kind of tower tray whirlwind-type pre-separation dehydration absorption tower is provided; Under not changing the effect situation of double-barrel separator in the flow process; Through the absorption tower internal structure change; Adapt to and contain the tower tray whirlwind-type pre-separation dehydration absorption tower that liquid changes in the gas, to realize that water dew point is up to standard under the multi-state.
The technical scheme that the utility model adopts is: tower tray whirlwind-type pre-separation dehydration absorption tower is characterized in that: comprise the absorption tower body, absorbing tower body is the vertical barrel structure, absorbs tower body and is located on the skirt skirt and basic fixed; The gas import is fixed on and absorbs on the tower body, and the gas import communicates with the air inlet distribution cavity, in the air inlet distribution cavity swirler-is arranged; There is partition panel swirler-delivery port upper end, and the partition panel upper end is fixed with tower tray, and the tower tray top and bottom have triglycol import and triglycol outlet respectively; Triglycol import and triglycol outlet are inwardly stretched into by the absorption tower is external; The triglycol outlet is in the lower end of tower tray, and the triglycol import is in the upper end of tower tray, and spray catcher is arranged at tower tray top; The gas outlet is arranged at the top that absorbs tower body; Leakage fluid dram is arranged at the bottom that absorbs tower body, and drainage tube is arranged at the bottom of air inlet distribution cavity.
Described skirt and upper end that absorbs the tower body joint face and having heaters import and export on the wall that absorbs tower body.
Described spray catcher can be the horizontal spray catcher, and horizontal spray catcher plane is vertical with absorption tower body medullary ray.
Described spray catcher also can be rectilinear spray catcher, and rectilinear spray catcher plane is parallel with absorption tower body medullary ray.
Principle of work: consult Fig. 1.Sweet natural gas radially gets into from gas import 3 and absorbs in the tower body 2, and gas carries out the gas-liquid separation first time through swirler-4; Gas after the separation gets into the inlet of tower tray 5 from swirler-4 tops output, and with the absorption that crosses of from top to down triglycol in the tower tray 5, after just adsorbing through triglycol, wherein water dew point can be far below the requirement of outer gas transmission dew point; Gas continues to rise, and gets into spray catcher 6, removes 99% saturation water, can tackle the triglycol more than 99% in the gas, thereby reduces the triglycol loss, handles qualified Sweet natural gas and gets into outer communication system.The liquid that advances tower gas-liquid separation for the first time and tackle through spray catcher 6 flows into liquid storage cylinder.Liquid storage cylinder is provided with level monitoring.Consider north cold in winter, in liquid storage cylinder, be provided with heating coil.Vertically arranged spray catcher can be avoided the liquid flooding that causes under the atmosphere speed.
The beneficial effect of the utility model: the utility model tower tray whirlwind-type pre-separation dehydration absorption tower, Sweet natural gas radially get into from gas import 3 and absorb in the tower body 2, and gas carries out the gas-liquid separation first time through swirler-4; The output of gas after the separation from swirler-4 tops, the inlet of entering filler 15, through filler 15 absorption, just through after the triglycol absorption, wherein water dew point is far below the requirement of outer gas transmission dew point; Gas continues to rise, and gets into spray catcher 6, removes 99% saturation water, can tackle the triglycol more than 99% in the gas, thereby reduces the triglycol loss, handles qualified Sweet natural gas and gets into outer communication system.
