METHOD OF DETECTING EMERGENCY LEAKS OF PIPELINE FOR ENVIRONMENT PROTECTION Russian patent published in 2016 - IPC F17D5/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas equipment, which provides protection from pollution near pipeline. Method of detecting leakages of transport pipeline of liquid or gaseous hydrocarbons or mixtures thereof, involves construction of a "pipe in pipe" structure, consisting of a pipeline and an outer jacket made of sealed sections equipped with gas outlet devices - at top points of pipeline route and nozzles with shutoff valves for removal of liquid in drain bends at lower points of pipeline route. Each section is filled with a control liquid or gas and is equipped with pressure and temperature control means, which are connected with system for collection, processing and transmission of information on leakage in measuring and computing system. At pressure change control of liquid or gas in sections, emergency control algorithms are used.

EFFECT: higher efficiency of protecting environment from contamination near pipeline.
