FIELD: main gas pipelines.
SUBSTANCE: group of inventions relates to the main pipeline transport of gas and is intended for emptying gas without venting it into the atmosphere from the equipment of adjacent compressor shops of the main gas pipeline connected by inter-shop ridges. The technical task of the claimed technical solution is to create a method for pumping gas and a system for its implementation from the equipment of two adjacent compressor shops connected by inter-shop ridges using only one technical device: an ejector. A method is proposed for pumping gas from the equipment of compressor shops of the main gas pipeline connected by inter-shop ridges at the entrance and exit with shut-off valves installed on them, including opening a shut-off valve at the entrance to the ejector connected to the inter-shop ridge for pumping the working shop, opening a shut-off valve at the exit of the ejector connected to the inter-shop ridge for suction of the working shop, the opening of the valves of the pipelines supplying the pumped gas from the equipment of the stopped compressor shop to the ejector and the closing of all these valves after pumping is completed is achieved by pumping gas from two adjacent shops connected by inter-shop ridges using a single technical device: an ejector. The result coincides with the task and is achieved due to the fact that in the system of pumping gas from the equipment of the compressor shops of the main gas pipeline, each of which is connected to the neighboring shop by inter-shop ridges at the entrance and exit with cut-off valves installed on them, having technological pipelines, gas purification systems and cooling systems connected to the input and output collectors, connected in turn to the input and output inter-shop ridges, one ejector is installed between the latter for two neighboring shops, moreover, the inlet of the ejector is connected by a pipeline with a shut-off valve to an inter-shop ridge at the exit of each of the workshops, the outlet of the ejector by a pipeline with a shut-off valve is connected to an inter-shop ridge at the entrance of each of the workshops, and the inlet of the pumped gas to the ejector with a shut-off valve is connected in each of the two workshops through the corresponding shut-off valves with suction and discharge collectors.
EFFECT: creation of method for pumping gas from the equipment of compressor shops of the main gas pipeline connected by inter-shop jumpers at the entrance and exit with shut-off valves installed on them, including opening a shut-off valve at the entrance to the ejector connected to the inter-shop jumper for pumping the working shop, opening a shut-off valve at the exit of the ejector connected to the inter-shop jumper for suction of the working shop.
