Low-density polyethylene (LDPE) resins are used to produce a range of general-purpose and high-performance applications, which include blown and cast film, extrusion and coating, and rotational and injection molding. ROTTERDAM, Netherlands, Aug. 25 /PRNewswire/ -- LyondellBasell Industries announces the launch of Lupotech A technology for the production of specialty low density polyethylene (LDPE) and ethylene vinyl acetate (EVA) products. This high-pressure autoclave process technology is optimized for the manufacture of advanced products with demanding .POLYETHYLENE PRODUCTION TECHNOLOGIES PE Polymerization Techniques The route to PE falls into two categories: 1. High pressure polymerization • Produces LDPE • Operating pressure ranging from 1000 to 3000 barg • Operating temperature from 80 to 300 °C • Autoclave or tubular reactor • Free radical catalysts using initiators (peroxides)
From plastic bags to containers, LDPE's ease of processing and durability make it an essential in modern manufacturing. SCGC™ LDPE is a low-density polyethylene resin produced by an autoclave process, a technology developed by ICI Co., Ltd., suitable for extrusion coating and lamination applications used in flexible packaging and aseptic box. The chapter presents a hands-on workshop for simulating an autoclave high-pressure (HP) LDPE process. It also presents an effective methodology for estimating the kinetic parameters based on plant data in the development of simulation and optimization models for commercial polyolefin processes involving free radical polymerization. Another .The first LDPE/EVA (Low Density Polyethylene / Ethylene Vinyl Acetate) autoclave process was introduced in 1938. In this type of application, a mix of pressurized ethylene gas and catalysts is stirred at high temperature in a vessel. The stirrer is turned by an electric motor which is in line with the vessel.
LDPE autoclave process LDPE is produced either in a tubular reactor (PFTR, LDPE tubular process) or in a high-pressure, continuous stirred tank reactor (CSTR, LDPE autoclave process). In both process designs the very high pressures require very special, thick-walled equipment and fatigue is a major design aspect for the applied pumps and compressors. In the LDPE .

In general autoclave LDPE outperforms tubular LDPE with respect to neck-in. The draw down limit for tubular LDPE on the other hand is higher than for autoclave. The work presented here provides technical details of the benefits of blending tubular LDPE with autoclave LDPE for extrusion coating applications. For a lab scale line, it is shown that at 30 to 50% tube resin . Process Summary. The Autoclave Reactor Polymerization of Ethylene is a non-catalytic Process that operates with Organic Peroxides as Radical Initiators at an operating pressure from 1,300 to 2,000 bar and a Reactor Temperature of up to 310°C. The aim of the present work is the development of a practical model for an industrial high-pressure polyethylene plant. The reactor considered in this work is the adiabatic slim type autoclave .Detailed models of industrial Low-density polyethylene (LDPE) autoclave reactors have been built by integrating several advanced modeling concepts: (a) An advanced thermodynamic model based on the Statistical Association Fluid Theory (SAFT) γ-Mie Equation of State, which represents molecules as chains of distinct functional groups [1-3]. .
