Description
Technical field
The present invention relates to a kind of multiphase flow blender, relate to a kind of distortion hole chip oil-gas-water three-phase flow static mixer specifically.
Background technology
The industry of flow process such as petrochemical industry, Coal Chemical Industry type is the pillar industry of the national economic development, is to ensure that China reaches the important foundation of the level of medium-developed country at mid-21st Century.Mobile corrosion is that flow process type commercial plant maximizes, the operating condition harshnessization, ubiquitous failure phenomenon in the evolutions such as raw material poor qualityization, hydrogenation reaction outflow air-cooler system (Reactor Effluent Air Coolers particularly, be called for short REAC), heat exchanger system, the normal three top systems that reduce pressure are at oil, gas, during carrying, water multiphase relates to heterogeneous flowing, heat and mass, complex processes such as phase transformation corrosion, the tube bank that causes is stopped up, mobile corrosion failure accident such as booster has tangible locality, sudden and risk has become such device safety of restriction, stable, the significant obstacle of long-term operation.
Existing result of study shows: frequent failure and the deposition of the ammonium salt crystallization in the course of reaction of hydrogenation REAC tube bank, heat exchanger tube are closely related.Because feedstock oil is rich in the compound of sulphur (S) and nitrogen (N), and contain part chlorine (Cl) change thing, after hydrogenation reaction, change NH into
3, H
2S and HCl, the NH that reaction generates in heat exchanger tube or air cooler tube bundle
4Cl and NH
4HS can directly become solid crystals by vapor condensation, is lacking obstruction tube bank rapidly under the situation of aqueous water.Usually need at the ammonium salt of heat exchanger front and back water filling in REAC upstream with the wash crystallization deposition for avoiding ammonium salt to stop up tube bank.But because physical property differences such as the density of oil, gas, water three-phase stream, viscosity make its flow condition difference very big, even if water injection rate fully still can't fully effectively not wash ammonium salt if mixed effect is good.Although the hydrogenation high-pressure air cooler system of external certain factory requires to carry out the water filling of capacity according to API 932-B, and guarantee that there is the aqueous water of 25% water filling total amount in the air cooler entrance, but because mixed effect is inhomogeneous, can't effectively wash the ammonium salt of crystallization deposition, dissect and find that the first comb bundle of air cooler tube bundle serious ammonium salt occurred and stopped up the tube bank phenomenon.
For guaranteeing the abundant mixing of oil, gas, water multiphase, improve mixed effect, the research and development high efficiency static mixer is the key point that solves such problem.But regrettably, characteristics such as the static mixer in the chemical industry is mainly used in processes such as gas/gas mixing, gas/liquid mixing, liquid/liquid mixing, extraction, multiphase flow reaction, augmentation of heat transfer, and existing blender exists complex structure, manufacturing cost height mostly in the process that multiphase flow mixes, the mixed process energy loss is big, mixed effect is not remarkable.Particularly require the oil-gas-water three-phase to flow well-mixed place, be subjected to the restriction of factors such as dielectric object gender gap, make the element length of blender lengthen greatly, the pressure loss of fluid increases, and also arranges to pipeline configuration simultaneously and brings difficulty.
Summary of the invention
The object of the present invention is to provide a kind of distortion hole chip oil-gas-water three-phase flow static mixer, can make quick, the efficient mixing of oil-gas-water three-phase stream short distance, can effectively avoid easy crystallographic component (NH in the multiphase flow course of conveying
4Cl, NH
4HS or other solid-phase media) crystallization deposition stop up the tube bank problem, significantly promote hydrogenation air-cooler system, heat exchanger system, normal the reduce pressure moving corrosive power of anti-current of three top systems, prolong safe, stable, the long-term operation of such device systems.
