Siemens Compressor Automation (SCAUT)

Published on : Tuesday 30-11--0001

Siemens Compressor Automation solution (SCAUT) is based on the world’s leading automation system family, Siemens SIMATIC S7.

SCAUT is a standardized system designed to meet your needs regarding operation, monitoring, control and protection of complete compressor trains.

This means that your compressors, drives and all auxiliaries run at the highest efficiency adjusted to your process requirements.

SCAUT is designed in accordance with the international standards of IEC (International Electrotechnical Commission).

A large variety of configurations allows for the implementation of flexible machine concepts.

Compressor Control

Anti-surge control designed to cover even the most complex tasks such as variable molecular weight, fast closing discharge valves or increasing suction temperature during recycling
Performance control acting on mass flow, suction- or discharge-pressure including limiting functions such as discharge pressure or motor-current
Load-sharing controller for parallel trains

Integrated Steam Turbine Control

Speed governors integrated into the SIMATIC S7 PLCe
Safeguarding functions, such as excessive temperature or minimum flow protection
Additional control of e.g. extraction pressure or inlet pressure
Automatic ramp-up to minimum governor speed according to predefined start-up curves including the avoidance of up to two critical speed bands

Flexible Modular Redundancy

As sensors and actuators are the weakest parts of an instrument loop, any redundancy concept should start with the appropriate number of field devices. (Typical fault rate split for a loop (according to TÜV): Sensor 35% - PLC 15% - Actuator 50%)The Siemens SCAUT system is designed to match the PLC and field device redundancy in order to:

Minimize costs
Maximize availability

Safety-integrated System

Up to SIL3 certified loops according to IEC 61508 for safety-related functions
