Abstract
Natural gas may consider the most
popular energy source in recent era and the demand
for it in recent years has been dramatic. However,
natural gas is existed in deep reservoirs so it may
contents many impurities for instance, hydrogen
sulphide, carbon dioxide and mercury. Indeed, these
impurities may cause several technical problems for
instance, corrosion and environment pollution.
Therefore, raw natural gas should be purify before
processing it to global gas markets and amine gas
sweetening process may consider the most common
technology to remove acid gases from natural gas
stream. Thus, this study aims to treat a given
composition natural gas stream with a moderate
hydrogen sulphide contents about 2500ppm vie
engineering mathematical calculations for MEA
circulation rate that was about 490 gpm. The amine
circulation rate is considered quite important amine
gas sweetening parameters that should be at optimum
value to achieve optimum acid gas removal and meet
the product requirement. Thus, the amine circulation
rate examined by material balance calculations for
amine contactor tower. As a result, it is found that 490
gpm amine circulation rate is an effective value to
reduce hydrogen sulphide contents to 4ppm which it
meets the gas pipelines and gas sell contracts
specification.
