Defoaming coalescing separator

Abstract

The invention relates to a defoaming coalescence separator which comprises a skid seat, a defoaming coalescence separator body, a pipeline, a valve, an instrument, a control system and the like, wherein the defoaming coalescence separator body, the pipeline, the valve, the instrument, the control system and the like are mounted on the skid seat. The defoaming coalescence separator body comprises a barrel, a sand discharge port is formed in the bottom end of the barrel, an exhaust port is formed in the top end of the barrel, and an air inlet is formed in the middle of the barrel; a gas distribution pipe, a primary collision structure, a secondary collision structure, a defoaming coalescer and a tail end interception structure are sequentially arranged in the cylinder body from bottom to top; the first end of the gas distribution pipe is connected with the gas inlet, and the second end is provided with a first collision structure. According to the defoaming coalescence separator disclosed by the invention, gas-liquid separation is accelerated by utilizing the first collision structure, and part of foam can be broken, so that subsequent defoaming coalescence treatment is facilitated; by means of the second collision structure, the situation that foam-containing gas rapidly rises after primary collision and excessively loads the defoaming and coalescence section can be avoided, meanwhile, the structure can increase the separation process of fluid, and the separation effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of natural gas processing, and in particular relates to a defoaming and coalescing separator. Background technique [0002] During normal production of most gas wells, the flow state in the wellbore is annular mist flow, and the liquid is carried by the gas to the surface in the form of droplets. The gas presents a continuous phase while the liquid presents a discontinuous phase. When the gas phase flow rate is too low to provide enough energy to make the liquid in the wellbore flow out of the wellhead continuously, the liquid will flow in the opposite direction of the gas and accumulate at the bottom of the well, and the gas well will begin to accumulate liquid. Fluid accumulation in the wellbore will increase the back pressure on the gas layer and limit the production capacity of the well. If the fluid accumulation in the wellbore is too large, the gas well will stop blowing completely. In addition, the l...

Problems solved by technology

[0004] However, after the air-water foam is sent to the ground, due to the poor defoaming effect of the existing separation equipment configured at the front end of the compressor and a large amount of water not separated, a large amount of foam, water and sand are directly poured into the compressor system without time to separate , resulting in frequent high liquid level shutdown of the compressor, blockage and damage of the inlet conical filter, damage to the intake valve and valve seat, etc., resulting in frequent shutdown of the compressor unit

The above problems will cause difficulties for on-site production and management, and increase the cost of operation and management
