Stainless steel corrugated packing

Stainless steel corrugated packingThe application in aniline tower is mainly reflected in its excellent mass transfer performance, corrosion resistance, and structural stability.

Mass transfer efficiency and structural advantages:The stainless steel regular packing adopts a corrugated structure design, which increases the gas-liquid contact area, and optimizes the flow path through regular arrangement, significantly improving mass transfer efficiency. For example,In the renovation of the benzene washing tower, the resistance of 125Y and 250Y fillers was successfully reduced from 1kPa to 0.6kPa, verifying their applicability in negative pressure operation. ‌

Corrosion resistance and long-term stability:adoptMade of 304 and 316L stainless steel materials, it can withstand chemical corrosion and high temperature environments, and is suitable for the production needs of aniline that is exposed to corrosive media for a long time. For example, the benzene washing tower in a coking plant experienced corrosion of the packing due to the presence of sulfides in the medium. After replacing the stainless steel regular packing, it operated stably. ‌

Industrial application cases:In the process of benzene removal from coke oven gas, stainless steel structured packing has successfully replaced traditional steel mesh packing, improving processing capacityMore than 30% and lower pressure drop. Its modular installation method also simplifies the maintenance and expansion process of the aniline tower

Stainless steel corrugated packingAfter selecting suitable packing materials, it is necessary to use appropriate liquid distributors to ensure the mass transfer effect of efficient and regular packing materials. The liquid distribution points should also ensure a certain density and flow intensity of the liquid spray points. So our company installs a tray type liquid distributor in the bottom packing layer of the packed tower. While ensuring uniform distribution of the liquid, the liquid flow intensity at each distribution point is uniform, which can achieve the mass transfer performance of the packing layer and better guarantee the process performance.

Stainless steel corrugated packing is widely used in unit operations such as distillation, absorption, and extraction. The product has been successfully applied in various facilities in refining and petrochemicals. For example: three-phase separator corrugated plate, coalescer packing, oil-water separation packing, lubricating oil and asphalt vacuum device, atmospheric crude oil tower, FCC vacuum tower, coking fractionation tower, high-pressure absorption/stripping device, secondary absorption and lean oil absorber, natural gas dehydration device, ethylene water quenching tower, etc. Due to the advantages of high flux, low resistance, high efficiency, strong anti clogging and anti fouling ability of corrugated packing for metal stainless steel orifice plates. Specially suitable for atmospheric pressure and moderate vacuum distillation of organic compounds with pollution hazards, such as ethanol, ethylbenzene/styrene, fatty alcohols, ethylenediamine, cyclohexane/cyclohexanol, ethylene glycol, fatty acids, mixed CO2, H2S, HCl, ClO2, Cl2, etc. In the design of new and old tower renovations, it is used to replace bulk packing materials such as Bao'er rings and certain plate towers. Especially in the renovation of large towers, it has significant economic effects on improving product output and quality, and reducing energy consumption. The main materials for producing stainless steel orifice plate corrugated packing include 201, 304, 316L, aluminum alloy, titanium, carbon steel, etc. The specifications, models, and materials should be selected according to the design needs of the packing tower.
