Abstract

The invention discloses a tubular parallel flow type gas-liquid contact absorber which comprises a gas steady flow straight pipe section, a gas contraction acceleration section, a gas dispersion expansion section and a gas-liquid uniform mixing mass transfer absorption section which are connected in sequence; liquid absorbent injection atomization parts are arranged in the gas contraction acceleration section and the gas dispersion expansion section; each of the liquid absorbent injection atomization parts comprises a built-in ellipsoidal flow guide cone and a trapezoidal cone, a flow guide cone liquid annular flow channel is arranged in the ellipsoidal flow guide cone, an outer pipe liquid annular flow channel is communicated with the flow guide cone liquid annular flow channel through aplurality of liquid annular flow channel connecting pipes, and a plurality of liquid incident small holes are evenly distributed in the outer wall face of the flow guide cone liquid annular flow channel in the circumferential direction, an auxiliary atomized gas flow channel is axially arranged in the ellipsoidal flow guide cone, and an auxiliary atomized gas circular seam is formed in the end face of the tail portion of the ellipsoidal flow guide cone. Purification treatment of natural gas dehydration and deacidification under different working conditions can be achieved, the gas-liquid masstransfer efficiency is high, the structure is compact, the treatment amount is large, operation is easy, and the gas-liquid flow application range is wide. The device is especially suitable for an offshore platform to replace a traditional absorption tower in a natural gas dehydration or deacidification process.

Description

technical field [0001] The invention relates to natural gas purification treatment equipment in the process of oil and gas exploitation, in particular to a tubular parallel-flow gas-liquid contact absorber for removing gaseous water and acid gas. Background technique [0002] As we all know, the natural gas extracted from the formation inevitably contains impurities such as water, dust particles, natural gas and hydrogen sulfide. On the one hand, acid gases such as carbon dioxide and hydrogen sulfide contained in natural gas will not only reduce the combustion calorific value of natural gas, but also corrode natural gas pipelines and equipment. On the other hand, the gaseous water (or gas phase water) contained in natural gas will be precipitated as liquid water when the pressure increases or the temperature decreases. These liquid waters will not only combine with some low molecular weight hydrocarbons to form hydrates and cause pipeline Blockage or equipment damage, and w...
