Regarding the initial manufacturing issues of Mellapak fillers
Thread Content
I have seen literature stating that the MELLAPAK metal plate corrugated packing, publicly introduced by Sulzer in 1977, is made by stamping various metal sheets with a thickness of 0.2 mm, with small holes having a diameter of 4 mm on them. The Intalox Structured packing developed by the American company Norton in the 1980s features perforated half-pieces with a special texture on their surface… Can this be interpreted as meaning that the plate corrugated packing originally developed by Sulzer had no texture and was smooth? No embossing? Has anyone seen any related reports or information?
Sulzer’s packing materials vary depending on the application: from 40Y and 64Y high-anti-clogging types (without drilling or surface treatment) to 125Y, 250Y, 350Y, and 500Y types, which all have surface treatment applied. Surface treatment not only increases the strength of the packing but also enhances the specific surface area for gas-liquid mass transfer as well as the efficiency of this transfer. I have some basic knowledge of Sulzer’s products; if you’re interested, you can add me on WeChat at 15395882727, mentioning HaiChuan and your company name
Hello! You should be fairly familiar with the history of packing materials. I’m just wondering whether the plate corrugated packings manufactured by Sulzer originally, such as the 125Y type, had any surface treatment applied to them
Plate corrugated packing should be used in limited applications, such as oil-water separation and situations with high levels of fouling. The 40Y and 64Y corrugated packs do not have any surface treatment; Sulzer, on the other hand, applies a special treatment to the surface of its packing to improve its efficiency. Are you asking this question for the purpose of writing an article? Is studying whether to wither the flowers also part of your research?
