Natural feed gas to the pressure 4.7 MPa and a temperature of 25,9 ¬ ° goes to install
gas separation (Figure 7), where it is cooled in a heat exchanger, passes through a separator
to separate the condensed moisture and solids. Further, the gas is dried in the zeolite
adsorbers and through the separator is sent to the column demetanizatora. Bottoms
demetanizatora sent for further separation of gas, and from the top of demetanizatora
cleaned and dried commercial gas fed into the main pipeline Hiva Beyneu.
Indicative of the natural gas commodity:
Methane - 98.59%
Ethan - 0.0012%
Nitrogen - 0.0123%
Carbon dioxide - 0.0006%.
Part of the marketable gas is used for own needs at the plants producing ethylene and
polyethylene, for regenerating the zeolites (after the fuel system).
Discharges from safety valves separators adsoberov, demetanizatora can enter the
collector dry jet separator and then to the torch to burn as needed.
Solid waste is spent zeolite adsorbers natural gas dehydration.
Bottoms demetanizatora enters the column deetanizatora where stands ethane,
commonly used in the production of ethylene polymer quality. Bottoms deetanizatora in the
column depropanizer produces propane and then in the column debutanizer produces
butane. Propane and butane are the foundation of liquefied natural gas, which accumulates
in the gas-holder (the field) Mercantile Park, from time to time are shipped by tankers to the
consumer.
Bottoms debutanizer is a light gas condensate, which is collected in two PBC
Mercantile Park, as well as periodically for condensate is sent to the NOE Akchalak and
then the consumer - oil refineries - for the production of motor fuels.
