AUTOMATED PROCESSING PLANT OF ASSOCIATED PETROLEUM GAS TO CONVERSION GAS OF IMPROVED COMPOSITION Russian patent published in 2012 - IPC F25J3/02 C10L3/06 

FIELD: machine building.

SUBSTANCE: automated plant consists of tubular converter 1, service tank 2, heat exchangers 3 and 4, steam generator 5, cutoff valves 11-15, compressors 16 and 19, exhaust fan 22, jet mixer 25, three-way valve 26, and dosing pump 27. Motors 17, 20, 23 and 28 of compressors, exhaust fan and dosing pump are equipped with static frequency converters 18, 21, 24 and 29. Plant is equipped with temperature sensors 33 - 45, pressure sensors 46-55, flow sensors 56-61, level sensors 62, dielcometres 63 - 66 and conductometre 67. The plant control is implemented by means of distributed-integrated system consisting of personal computer and microprocessor controller, which are in-parallel connected to each other via information channels and channels of control actions. Outputs of microprocessor controller are directed to drives of cutoff and three-way valves and to static frequency converters.

EFFECT: invention allows improving the gas composition with implementation of rational and fail-safe control modes and improving power and environmental characteristics.
