high pressure in the supply line of ethane in ethane pyrolysis furnace recycle will be sent to
the fuel system. All these flows are separated in a separator of fuel to prevent the ingress of
liquid to gas burners of steam boilers, pressure or other gas burners. Periodically, the
condensate is drained into a container of liquid fuel.
Separated fuel gas enters the sewer system of fuel gas from which the boilers are fed
high-pressure steam, flare header, the pyrolysis furnace and other consumers.
The composition of the fuel gas can be as follows (% vol.):
Hydrogen - 4.14
Methane - 94.14
Ethan - 1,04
Bhutan - 0,04
Nitrogen - 0.61
Carbon dioxide - 0.03
In the case of high-pressure fuel gas is supplied to the torch.
In a separate separator off-gas is separated fuel gas for pyrolysis furnaces. This fuel
gas is a mixture of methane gas from the installation of gas separation, methane waste gas
swing adsorption regeneration of adsorbents with the installation of ethylene.
In the case of high-pressure part of the fuel gas is discharged into the flare separator.
At higher pressure through the control valve gas will be dumped right on the Torch.
Subsystem of liquid fuel. Liquid fuel from the tank flows through the evaporator
refrigerator in a container for liquid fuel. This also comes from the liquid separator fuel gas
separator off-gas.
In the capacity of the liquid fuel coming from the five-step hydrocarbon steam
turbine compressor, together with hydrocarbon quench column and oil cleaning apparatus.
Liquid fuel is almost entirely composed of C5 + fraction Higher.
In the capacity of the liquid fuel pressure is kept to a minimum, the gas phase is
discharged to the flare.
