  Performance Improvement of Thermosyphon Heat Exchangers by Using Two Kinds of Working Fluids

  摘要：

  In this study, the concept of introducing two-fluid thermosyphons is examined. Calculations were performed for both low and high temperature ranges with parallel and counter-flow arrangements. For lower-temperature application, 125 degreesC > T-hi > 75 degreesC, use of ammonia in some rows and water in the rest of the thermosyphon can slightly improve the associated heat transfer performance for balanced counter-flow arrangement. However, for balanced parallel-flow arrangement in both low-and high-temperature applications, the concept of using two-fluid thermosyphons may not be feasible. The use of two-fluid thermosyphons is especially advantageous for high-temperature applications. For instance, in range of 375 degreesC > T-hi > 350 degreesC the two-fluid thermosyphons (Dowtherm A-water) shows a 15-99% increase of heat transfer performance relative to Dowtherm A alone.

  The present invention provides a process for producing an alkyl ether of a phenol from a phenol and an alcohol at a selectivity and a yield higher than in conventional processes, stably over a long period of time. The process is characterized by alkyl-etherifying a phenol with an alcohol in the presence of an oxide catalyst comprising an alkali metal as a constituent element.

  本发明提供了一种用苯酚和醇生产苯酚烷基醚的工艺，其选择性和产率均高于传统工艺，且能长期稳定地生产。该工艺的特点是在由碱金属作为组成元素的氧化物催化剂存在下，将苯酚与醇进行烷基醚化。
