Abstract

The invention discloses a safe processing system and a safe processing method for a release medium of an intermittent pump station of a liquid state ethane pipeline. The liquid state ethane is conveyed by a liquid state ethane pipeline. An in-station cut-off valve, an out-of-station cut-off valve and a pressurizing pump are arranged on the liquid state ethane pipeline. The safe processing system comprises a non-planed release processing system, a planed emptying system, a recovery system and a control system. Based on the operating characteristics of a liquid state ethane long conveying pipeline pump station, two independent release medium processing modes are established by adopting a policy of directly burning a non-planed release medium and recovering a planed emptied medium efficientlyaccording to characteristics that recovered ethane is relatively good in economic value and is relatively low in released temperature by combining a safety protecting idea of the intermittent pump station of a conventional oil product pipeline, so that a condition of constructing a high pressure tank to receive the non-planed release medium is avoided, and a trunk line stored medium is recoveredefficiently.

Description

technical field [0001] The invention belongs to the technical field of liquid ethane transportation, and in particular relates to a system and method for safely treating the discharge medium of an intermediate pumping station of a liquid ethane pipeline. Background technique [0002] With the development of natural gas processing technology and the development of high-efficiency natural gas utilization technology, the recovery efficiency of ethane in natural gas has been continuously improved, and its long-distance transmission technology needs to be vigorously developed to expand the scope of application. Ethane product is a kind of light molar mass among natural gas by-products, with high saturated vapor pressure, critical temperature of about 32°C, and critical pressure of about 4.5MPa, so it is possible to carry out single-phase transportation in gas or liquid state. Compared with gaseous ethane pipeline transportation, liquid transportation has the remarkable characteri...
