Abstract: Shell-and-tube devices typically require regular maintenance. Described herein is an automated method for tracking the status of individual tubes during maintenance activities and recording status data for review and analysis. Status data may optionally be reported in real-time summary format and/or used to predict time-to-completion. The method helps to reduce the expense of performing maintenance activities in shell-and-tube devices, including shell-and-tube reactors and heat exchangers.

Abstract: A process for recovering (meth)acrylic acid includes distilling a mixture comprising (meth)acrylic acid in a finishing column at less than atmospheric pressure to produce a finishing column overhead stream and a finishing column bottoms stream. An overhead aspirating direct contact condenser system at least partially condenses the finishing column overhead stream to form a finishing column overhead condensate and an overhead non-condensables vent stream. A finishing column vapor-phase side draw may also be recovered. An aspirating direct contact condenser system may be used to at least partially condense the vapor-phase side draw.

Abstract: Shell-and-tube devices typically require regular maintenance. Described herein is an automated method for tracking the status of individual tubes during maintenance activities and recording status data for review and analysis. Status data may optionally be reported in real-time summary format and/or used to predict time-to-completion. The method minimizes omission errors and helps to reduce the expense of performing maintenance activities in shell-and-tube devices, including shell-and-tube reactors and heat exchangers.
