METHOD FOR DETERMINING HEAT TRANSFER COEFFICIENT OF GAS IN GAS-COLLECTING TRAIN TO ATMOSPHERE IN AUTOMATED PROCESS CONTROL SYSTEMS OF COMPLEX GAS TREATMENT PLANTS OF GAS-CONDENSATE DEPOSITS OF FAR NORTH Russian patent published in 2013 - IPC F17D5/00 

FIELD: machine building.

SUBSTANCE: telemetry means are used for measurement of the following: gas temperature at the beginning of the train - t_b and volumetric gas flow rate of cluster under normal conditions - Q, ambient temperature - t_a, and actual gas temperature t_ac at the end of the train is measured by means of automated process control systems. Measured t_b, t_a, Q, t_ac are used for determination of the value of heat transfer coefficient to atmosphere K_ac, which is compared to its maximum allowable value A, and if the ratio of K_ac>A is determined, then the fact of disturbance of the normal operating conditions of wells and train is established.

EFFECT: improving determination accuracy of gas heat transfer coefficient to atmosphere and monitoring of its dynamics in real-time mode.
