摘要:

AbstractRemarks on the Degree of Automation of Chemical Processes. In the discussion of lean production, the degree of automation is very often called into question. Overengineering of automation functions is often presupposed. In order to rationalize this discussion, this contribution outlines the broad spectrum of automation functions, automation principles and automation structures. On this basis, terms like the degree of automation, the connectivity of automation function, etc. are defined. These terms build the basis of the adequate choice of the degree of automation. Factors determining this choice and its consequences are described.

摘要:

AbstractMathematical Models of the Morphological Development of Mycelium‐Forming Microorganisms. A significant proportion of the products produced by biotechnology come from mycelium‐forming microorganisms. The highly complex growth and product formation behaviour of these organisms places special demands on process control and on reactor design. This article demonstrates the possible contribution of mathematical models. Particular attention is directed to morphological aspects of an important class of organisms, viz. streptomy

摘要:

AbstractNew Thermoplastic Elastomers: Formulation; Compounding; and Material Properties. This article described novel thermoplastic elastomers (TPO) consisting of a PP matrix and a synthetic rubber phase crosslinked in a new way with organosilanes. The mechanical and rheological properties of the blend are determined primarily by the phase structures produced in the course of compounding. PE‐ULD can also be used as synthetic rubber in place of EP(D)M, with the attendant advantage of reduced swelling in oil

摘要:

AbstractModelling of Mass Exchange of Volatile Organic Compounds in High‐Viscosity Media. Polymers may contain low‐molecular weight organic components as a result of incomplete reaction during polymerisation, contamination of the reactants, and undesired side reactions. Aqueous of polymers are usually applied to surfaces (emulsion paints, adhesives, paper finishing agents, etc.). Since low molecular components then escape into the air, they are removed after polymerisation by stripping the product with an inert gas. While the engineering used for this step is well developed, the mass transfer processes involved have received little yet controversial attention. This paper presents a mechanistic mathematical model which includes the mass transfer steps occurring during stripping in a stationary continuously operating apparatus with complete back‐mixing. Measurements of the position of phase equilibria and determination of the depletion achievable in an aerosol jet loop reactor demonstrate that, provided that the temperature of treatment exceeds the glass transition temperature, the stripping process is determined solely by the partition coefficients of the exchanged components between the phases, the hydrodynamic parameters, and the reactor operating conditions. This contradicts the claims of some authors that diffusion processes in the latex particles are of decisive impor
