STUDY ON NATURAL GAS LIQUID (NGL) RECOVERY SIMULATION STUDY

This project is about Natural Gas Liquid (NGL) Recovery in the plant. The main
objective of this project is to study on several technologies and process used in NGL
recovery nowadays via HYSYS simulation. In this study, the technologies used for
simulation are 3-S technology (twister), turbo-expander, and J-T valve expansion. For
NGL recovery process, the processes are based on Ortloff Engineer, LTD which is GSP,
OHR, RSV, RSVE, IOR, and SCORE.
The effects on different types of technologies used for controlling HCDP and to
produce lowtemperature were investigated. Moreover, the ethaneand propane recovery
with respect to compression power and C02-tolerant for different types on NGL
recovery processes were studied.
There are several steps need to be done so that the objectives of this project can
be achieved; define the problem, review the critical literature, define operating
conditions to the simulation, run the simulation, manipulate the technologies/processes,
collect the data for discussion, and draw the conclusion for this project.
Turbo-expander producesmuch lower temperature to the column compared with
twister and J-T valve. RSV and SCOREprocesses give the highest recovery for the same
compression power for ethane and propane recovery process respectively meanwhile
RSVE is more C02-tolerant compared with other ethane recovery process.
