Modeling Fouling Effects in LDPE Tubular Polymerization Reactors. 3. Computational Fluid Dynamics Analysis of a Reacting Zone

Autor: Michael L. Call, Allen L. Brown, Joe Hannon, Steve Hearn, Alberto Buchelli, Andrew Bird

Publikováno v: Industrial & Engineering Chemistry Research. 44:1493-1501

Fouling in a LDPE tubular polymerization reactor is caused by the polyethylene/ethylene mixture forming two phases inside the reactor. Some of the polymer-rich phase is deposited on the reactor's inside wall, which considerably reduces heat-transfer

Modeling Fouling Effects in LDPE Tubular Polymerization Reactors. 1. Fouling Thickness Determination

Autor: Steve Hearn, Alberto Buchelli, Michael L. Call, Andrew Bird, Allen L. Brown, Joe Hannon

Publikováno v: Industrial & Engineering Chemistry Research. 44:1474-1479

Fouling in a low-density polyethylene (LDPE) tubular polymerization reactor is caused by the polyethylene/ethylene mixture forming two phases inside the reactor. Some of the polymer-rich phase is deposited on the reactor's inside wall, which consider

Nonequilibrium Behavior in Ethylene/Polyethylene Flash Separators

Autor: Michael L. Call, Alberto Buchelli, John Franjione, Sundaram Ramanathan, Costas P. Bokis, Allen L. Brown

Publikováno v: Industrial & Engineering Chemistry Research. 43:1768-1778

In this work, we investigated various approaches for the modeling of the high- and low-pressure separator units downstream from a low-density polyethylene tubular reactor using the Polymers Plus software package. First, we examined the performance of

MSL: a model for W3C XML Schema

Autor: Matthew Fuchs, Jonathan Robie, Allen L. Brown, Philip Wadler

Publikováno v: WWW

Model Schema Language (MSL) is an attempt to formalize some of the core ideas in XML Schema. The benefits of a formal description are that it is both concise and precise. MSL has already proved helpful in work on the design of XML Query. We expect th

Physical Properties, Reactor Modeling, and Polymerization Kinetics in the Low-Density Polyethylene Tubular Reactor Process

Autor: John Franjione, and Michael L. Call, Alberto Buchelli, and Sundaram Ramanathan, Allen L. Brown, Costas P. Bokis

Publikováno v: Industrial & Engineering Chemistry Research. 41:1017-1030

In this investigation, we demonstrate our methodology in developing a comprehensive computer simulation model for the low-density polyethylene process in a tubular reactor using Polymers Plus. We use the perturbed-chain statistical associating fluid

Preference logics: Towards a unified approach to nonmonotonicity in deductive reasoning

Autor: Allen L. Brown, Toshiro Wakayama, Surya Mantha

Publikováno v: Annals of Mathematics and Artificial Intelligence. 10:233-280

The notion ofpreference is central to most forms of nonmonotonic reasoning. Shoham, in his dissertation, used this notion to give a single semantical point of view from which most nonmonotonic reasoning systems could be studied. In this paper, we stu

Exploiting the normative aspect of preference: A deontic logic without actions

Autor: Toshiro Wakayama, Allen L. Brown, Surya Mantha

Publikováno v: Annals of Mathematics and Artificial Intelligence. 9:167-203

This paper is an attempt to clear the following charge leveled against preference logics: preference logics rest upon the mistaken belief that concept construction can satisfactorily be carried out in isolation from theory construction (J. Mullen, Me

Definite clause programs are canonical (over a suitable domain)

Autor: Allen L. Brown, Howard A. Blair

Publikováno v: Annals of Mathematics and Artificial Intelligence. 1:1-19

For each first-order languageL with a nonempty Herbrand universe, we construct an algebraC interpreting the function symbols ofL that is a model of the Clark equality theory with languageL and is canonical in the sense that for every definite clause
