PLC APPLICATION: CHEMICAL AND PETROCHEMICAL

AMMONIA AND ETHYLENE PROCESSING: Programmable controllers monitor and control large compressors that are using ammonia and ethylene manufacturing.The PLC monitors bearing temperature, operation of clearance pockets,compressor speed,power consumption vibration, discharge temperature,pressure and suction flow.
DYES : PLC monitors and control the dye processing used in the textile industry. They match and blend colour to pre-determined values.
CHEMICAL BATCHING:The programmable logic controller controls the batching ratio of two or more material in a continues process.The system determine the rate of discharge of each materials and keeps inventory records. Several batch recipes can be logged and retrieve automatically or on command from the operator.
FAN CONTROL: PLC control fan based on a level of logic gases in a chemical production environment.This system effectively remove gases,when at a preset level of contamination reached,the PLC control the fan starting and stopping,recycling and speeds,so that the safety level are maintained while energy consumption are minimized.
