Description
Technical field
The invention belongs to liquefied petroleum gas storage Canning Technique field, specially a kind of LPG gas phase buried pipeline condensed liquid
Pumping equipment and its fluid-discharge method.
Background technique
Liquefied petroleum gas main component is propane, butane, propylene, butylene, and winter saturated vapor is pressed in 0.2MPa or so, this
When dew-point temperature at 3-5 DEG C, when the ground temperature locating for the pipeline is lower than 3 DEG C, just have condensed liquid (butane butylene is liquefied as revealing) analysis
Out.
Condensed liquid in gas phase pipeline not only increases the resistance of ducting, but also can damage gas compressor, and condensed liquid is timely
Discharge is most important for guaranteeing the safe operation of the station LPG.
Conventional LPG stores process pipe laying in filling project, and there are three types of forms, the first is the laying of ground low trestle, the
Two kinds are truss layings, the third is buried-pipe laying.
LPG gas phase pipeline is laid using ground low trestle, low spot draining valve is set, facilitate solidifying in discharge line
Analyse liquid.
LPG gas phase pipeline uses truss laying (laying height is 4.5 meter under runway), is then arranged in pipeline low spot and arranges
Condensed liquid is discharged in liquid valve.
LPG gas phase pipeline buried-pipe laying, laying depth is between 1.2-2 meters, and southern area is since low temperature is higher, no condensation
Liquid generates, and northern area winter is cold, and ground temperature is lower, once the ground temperature near buried pipeline lower than dew-point temperature, in pipeline
Condensed liquid precipitation is just had, brings and seriously affects to operation.
Northern area LPG gas phase pipeline is less using buried-pipe laying based on the above reasons, even if having also needs using heating tape
Heat preserving mode avoids the condensed liquid from generating.
The pros and cons of three kinds of modes of existing LPG gas phase pipeline condensed liquid discharge:
(1) LPG gas phase pipeline is laid using ground low trestle, tapping valve is arranged in pipeline low spot, the method installation maintenance is easy
It is practical, but made troubles when pipeline is connect with loading arm to the current revolution of LPG tank car.
(2) LPG gas phase pipeline is laid using truss, and tapping valve is arranged in pipeline low spot, and truss is most at the method vehicle pass-through
Low clearance reaches 4.5 meters, and tubular service and maintenance are extremely inconvenient.
(3) LPG gas phase pipeline uses buried-pipe laying, and northern area improves medium temperature using electric-heating belt, to avoid coagulating
Analysis liquation goes out；Such method will increase power consumption, and replacement difficulty is larger when heating tape is easily damaged.
