Embodiment Construction

[0024] see now figure 1 , shows a shell and tube heat exchanger 9 for heat exchange between two process streams according to the present invention. The shell and tube heat exchanger 9 contains two different types of baffles (i.e., image 3 central baffles and annular baffles shown in ), the two different types of baffles to improve heat exchange and the resulting The manner of temperature distribution is provided within the exchanger.

[0025] Typically a first fluid (i.e. the first process gas) is introduced into the shell side of the exchanger (i.e. the chamber formed between the tubes and the shell) and a second fluid (i.e. the second process gas) is introduced into the tube side (ie into the tubes of the exchanger). The first fluid is pushed into the central portion of the exchanger when it passes the annular baffle, and it is pushed into the central portion of the exchanger when it bypasses the central baffle. peripheral part. Typically said annular baffles and centr...

Abstract

The present invention discloses a shell and tube heat exchanger that includes a baffle arrangement that improves the temperature distribution and flow pattern through the exchanger and / or is integral to the reaction vessel. The present invention also discloses methods of using the shell and tube heat exchanger, including methods involving the use of the shell and tube heat exchanger and a reaction vessel to generate a reaction product gas comprising trichlorosilane.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 439,199, filed February 3, 2011, and U.S. Nonprovisional Patent Application Nos. 13 / 355,303 and 13 / 355,309, both filed January 20, 2012 , all of which are incorporated herein by reference. technical field [0003] The technical field of the invention relates to heat exchangers, in particular to shell and tube heat exchangers with baffles. The technical field of the invention also relates to methods of using said exchangers, including methods involving the use of said exchangers and reaction vessels to generate reaction product gases. Background technique [0004] Many process systems, such as reactor systems, involve the use of relatively high temperature process streams and / or relatively low temperature process streams. Cooling and / or heating such process streams may require significant energy costs. To reduce such costs, the process ...
