Embodiment 1

[0021] In order to prevent the formation of natural gas hydrate, a methanol storage skid is set up at the well site or gas gathering station to store a certain amount of methanol for a certain period of time to meet the injection requirements of methanol inhibitors for the normal production of gas wells; and to overcome the inconvenience of moving the existing methanol storage device and cause equipment investment waste, and the alcohol injection equipment needs to be installed on site, the construction period is long, and the overall investment is high. This embodiment provides a method such as figure 1 The shown methanol receiving and storage skid-mounted device includes a methanol storage tank 4, which is arranged on a movable skid base 14, and the feed pipeline of the methanol storage tank 4 is arranged from right to left Quick connector 1 and shut-off valve one 2, the outlet pipeline at the bottom of the methanol storage tank 4 is connected to the methanol injection pump, ...

Embodiment 2

[0027] This embodiment provides a methanol receiving and storage skid-mounted device, including a methanol storage tank 4, the methanol storage tank 4 is arranged on a movable skid base 14, and the feed line of the methanol storage tank 4 runs from the right A quick connector 1 and a shut-off valve 1 are provided to the left, and the outlet pipeline at the bottom of the methanol storage tank 4 is connected to a methanol injection pump, and a shut-off valve 2 11, a filter 12 and a methanol outlet shut-off valve are arranged on the outlet pipeline from left to right 13. The bottom of the methanol storage tank 4 is also provided with a blowdown pipeline, and a shut-off valve 3 10 is set on the blowdown pipeline. The upper end of the methanol storage tank 4 is connected with a nitrogen pipeline 7 and a pump methanol return pipeline 8 .

[0028] At the same time, a check valve 3 is arranged on the feed line of the methanol storage tank 4 behind the cut-off valve 2, and a check valve...

Abstract

The invention provides a skid-mounted unit for receiving and storing methanol, comprising a methanol storage tank disposed on a skid which is movable. A feed line of the methanol storage tank is provided with a quick connector and a first cut-off valve; a bottom outlet line of the methanol storage tank is connected with a methanol injection pump; the bottom outlet line is provided with a second cut-off valve, a filter and a methanol outlet cut-off valve; the bottom of the methanol storage tank is further provided with a drainage line which is provided with a third cut-off valve; the upper end of the methanol storage tank is connected with a nitrogen line and a pumped methanol return line. The skid-mounted unit is simple in structure; all devices and auxiliary lines are integrated to the skid, moving and mounting are facilitated, and the requirement for step development of a gas field is met; meanwhile, reasonable allocation can be made according to the production conditions of a gas well, equipment investment waste is avoided, cost is saved, supplementing can be performed regularly according to the production requirements of the gas well and changes in the liquid level, attendance is totally not required, running is automated, monitoring is remote, safety and reliability are achieved, and labor intensity is reduced.

Description

technical field [0001] The invention specifically relates to a methanol receiving and storage skid. Background technique [0002] Natural gas hydrate is certain small molecular gas (N 2 , CO 2 、CH 4 、C 2 h 6 、C 3 h 8 etc.) snow-like crystals formed with liquid water. In severe cases, these hydrates can block wellbores, pipelines, valves and equipment, thereby affecting the normal operation of natural gas exploitation, gathering, transportation and processing. [0003] In order to prevent the formation of hydrates, hydrate inhibitors are usually injected into the pipeline during natural gas production. Natural gas hydrate inhibitors include: methanol, ethylene glycol, diethylene glycol, etc. Since the form of hydroxyl groups is similar to water molecules, according to the principle of similar miscibility, the water in natural gas is easily soluble in methanol, which changes the interaction between water molecules and reduces the partial pressure of water vapor on the ...
