vérification de l'nité de séchage de gaz naturel GLA/HBK

Abstract

The unit of GLA where our training course was carried out, currently treats an additional expenditure without knowing the consequences, then we carried out the checking of dimensions of the driers and the mass of the molecular sieve to see whether the unit is under or oversize or in another way if the unit is able or not to treat this substitute. According to calculations one found that the computed values are larger than those of the design, which means that the unit is under dimensioned. For not confronting problems, the solutions are : 1- Install another upstream flash drum dryers that help eliminate more free water and relieves sieve. 2- Reduce output of gas to treat and respect the value conceived by the design. 3- Install a fourth drier to treat the surplus of the load. 4- Increase the height of the sieve by (Dcalculed - Ddesign) and fill it by a mass of (mcalculed - mdesign) of the molecular sieve.
