Purpose
The compressor is designed to compress natural gas in the production of nitrogen fertilizers.
The unit components:
- centrifugal compressor made two-cylinder;
- the system for oil supply to the seals;
- governing system;
- anti-surge protection system;
- the system of control, monitoring, protection and signaling.
Design features
The compressor cylinders are installed on a common foundation frame. There are four stages in each cylinder. The cylinder casings are made of steel, with a horizontal split.The compressor is provided with hermetical end face seals. Oil is supplied to the end face seals by a screw pump. The pressure differential regulator maintains constant pressure differential of oil-gas.
The compressor is driven by the C-4,3-40,8 condensing turbine.
