STATIE DE USCARE GAZE CU TRIETILENGLICOL (TEG)

Statia de uscare gaze are rolul de a elimina o cantitate cat mai mare de vapori de apa din gazele provenite de la sonde sau din statiile de comprimare. Aceasta cantitate eliminata se reflecta in punctul de roua al gazului la iesirea din statia de uscare (valoarea acestuia sa fie cat mai scazuta,

Configuratia de baza : o contactor glicol o condensator glicol superior o schimbator de caldura TEG sarac/TEG bogat (treapta I) o vas separator de degazare o filtru particule TEG o filtru carbon activ TEG o coloana fractionare o refierbator TEG (incalzire cu arzatoare cu gaz) o coloana stripare TEG o acumulator TEG o pompe circulatie TEG o racitor TEG sarac (racire cu aer) o separator gaz combustibil o schimbator de caldura TEG sarac/TEG bogat (treapta II) o panou local de control

Optional poate fi echipata cu (depinde de parametrii gazului si cerintele beneficiarului) :

o racitor gaz o pompe de transfer auxiliare glicol o tanc stocare glicol o oxidizer

TRIETHYLENEGLYCOL (TEG) GAS DEHYDRATION STATION

The gas dehydration station has the purpose to remove as much as possible water vapour from the gas that comes from the weels or from the compression stations. This removed quantity is reflected in the gas dew point at the outlet from the dehydration station (its value to be at the least

Basic structure: o glycol contactor column o top glycol condensator (still reflux condenser) o lean/rich TEG heat excanger (stage I) o degasification separator vessel (flash drum) o TEG particle filters o TEG activated carbon filter o fractionating column (still column) o TEG reboiler (up heating with gas burners) o TEG stripping column o TEG collector (surge drum) o TEG circulation pumps o lean TEG cooler (air cooling) o fuel gas separator o lean/rich TEG heat exchanger (stage II) o local control panel

Optional it may be equiped with (according to the gas parameters and the customer requirements):

o gas cooler o additional glycol transfer pumps o glycol storage tank o natural draft thermal oxidizer
