OIL HEATING SYSTEM Russian patent published in 2015 - IPC E21B36/04 E21B37/00 

FIELD: oil-and-gas industry.

SUBSTANCE: oil heating system contains the AC or DC heating cable installed in zone of possible formation of asphalt-resin-wax deposits, the cable contains heating cores and steel or synthetic polymer armour. The heating cores are connected via the junction terminal cabinet to the control station, that ensures the set heating mode, parameters monitoring and set of protections. The control station includes casing, in which the terminal block is installed to connect the heating cable and power cable of the control station, power unit, switching on/off unit, GSM unit, control and monitoring unit. The power unit ensures DC or AC power supply of the heating cable. The switching on/off unit includes the circuit breaker and starter ensuring normal and emergency power switching on/off. GSM unit ensures the remote monitoring and control of the oil heating system. The control and monitoring unit includes a digital logic controller and control module of the universal power unit, ensuring control of the set mode of the cable heating, protection against short circuit, current leaks, exceedance of set current and voltage level, exceedance of set cable temperature and heated medium, control panel ensuring entry and updating of the current parameters and visual monitoring of the system operation.

EFFECT: increased efficiency of asphalt-resin-wax deposits prevention.
