English to Russian Tech/Engineering Petroleum Eng/Sci reactors

Добрый вечер, подскажите, пожалуйста, что за take off line/location, далее будет continuous takeoff nozzle - это линия отвода?

In series mode (bimodal operation) Reactor A product takeoff uses a single continuous take off line connecting to Reactor B. Flow in this line is not controlled directly. The Reactor A takeoff location (Bottom of Leg #4) is higher pressure than the entry to the Reactor B (Bottom of Leg #7).

Спасибо!
