Indirect evaporative cooler using membrane-contained, liquid desiccant for dehumidification
TL;DR: In this article, an indirect evaporative cooler is proposed for cooling inlet supply air from a first temperature to a second, lower temperature using a stream of liquid coolant and either liquid desiccant or purge air.
Patent
Process for the preparation of isocyanates in the gas phase
TL;DR: In this paper, homogenization and centering of the educt streams are used to prevent the formation of polymeric secondary products, which result in baked-on deposits in the reactor and a reduction in reactor service life.

Optimal Design of a Rotating Packed Bed for VOC Stripping from Contaminated Groundwater
TL;DR: In this paper, the authors studied the optimal design of an industrial-scale HiGee stripping process with conflicting objectives such as total annual cost (TAC) and total VOC removal under consideration.
Patent
Method for the production of isocyanates
TL;DR: In this paper, a method for producing polyisocyanates is described, comprising the following steps: amines are reacted with phosgene, hydrogen chloride, excess phos gene, and, if necessary, the solvent are separated from the reaction mixture.

The polyurethanes book
David Randall,Steve Lee +1 more
Abstract: DESCRIPTION Since the first Polyurethanes book was published in 1987, and reprinted with updates in 1990, the world of polyurethanes has changed dramatically. This edition has been completely re-structured, re-written and enlarged by approximately 50%. It provides a greater focus on the whole range of components used to produce polyurethanes, a more detailed analysis of environmental issues and extended views on the applications for polyurethanes. As with the previous editions, this book provides a comprehensive survey of these remarkable materials, again presented in a readable manner, and continues to provide both an easily-understood introduction for those with limited knowledge of chemistry as well as detailed coverage for the more chemically-minded.

Process for the preparation of (cyclo)aliphatic diisocyanates
TL;DR: In this article, a new process for preparing (cyclo) aliphatic diisocyanates by phosgenation of corresponding diamines in the gas phase by phosing of the vaporous diamines at 200 to 600 °C was proposed.
Patent
Process for the preparation of aromatic diisocyanates
TL;DR: A continuous process for the preparation of aromatic diisocyanates by phosgenation of corresponding diamines, in which the reaction is carried out in the gas phase is described in this article, where the mean contact time for the gaseous reactants is from 05 to 5 seconds with a mean deviation of no more than 6%
