Remote Control Panel for reciprocating compressor

ELECTROMACH received the order to design 5 complete remote control panels for controlling 10 reciprocating compressors.

Reciprocating compressor

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged. We can categorize reciprocating compressors into many types and for many applications. Primarily, it is used in a great many industries, including oil refineries, gas pipelines, chemical plants, natural gas processing plants and refrigeration plants.

Remote Control Panel

Each control panel consists of 4 interlocked units with 2 additional local control panels. The local control panels are EX certified and can be placed in the hazardous area. The local two-sides panels have a control box on one side and a pneumatic capacity system on the other side.

Each control unit monitors and regulates two compressors in parallel, an A and B compressor. The control units are also two-sided executed and will be placed in the safe area. At the front of the panel the components for monitoring and controlling are mounted, such as the redundant Allen Bradley PLC and the power distribution. The connection terminals and the Ex-i isolators for the field instrumentation are mounted on the back.

The panels will be used at the Khabarovsk refinery in Russia and are supplied to Technigas Reunidas, who are modernizing the refinery.

Khabarovsk refinery

This is the oldest and largest oil refinery in the Far East. The refinery, originally built in 1935, had an initial capacity of 8,000 barrels per day.
The initial purpose was to supply oil to the Soviet Pacific fleet and support the developing economy of the Russian Far East and Eastern Siberia.

After the completion of the modernization, which is scheduled for 2012, it is expected to produce between 70,000 and 90,000 barrels per day, depending on the market conditions. The refinery is then grown into a modern complex which meets the high national and international quality requirements.
