Abstract

Information about vent fluid flow through a confined spaces (13) in multiple processing facilities is sensed and transmitted to a remote location. Sensing includes obtaining a pressure differential of vent fluid flow across a filter or at different locations along a length of a flow line. The sensed information is transmitted using wireless communication means (51, 52). The vent fluid flow sensed at the multiple facilities is monitored at the remote location, and a need for corrective action is determined based on monitoring the flow. Monitoring units are used to transmit the vent fluid flow information, one or more of which are disposed at each processing facility. The monitoring units are transported in a transportation unit (78), which is equipped to secure multiple monitoring units within and protect the units from damage during transit. When venting at a particular processing facility is completed, the monitoring unit is transported to different processing facility.

Description

PCT PATENT APPLICATION REMOTE REALTIME MONITORING OF AN INDUSTRIAL VENTING SYSTEM [0001] This application claims priority to and the benefit of co-pending U.S. Provisional Application Serial No. 63/511,411, filed June 30, 2023, the full disclosure of which is incorporated by reference herein in its entirety and for all purposes. BACKGROUND OF THE INVENTION 1. Field of Invention [0002] The present disclosure relates to monitoring industrial venting performance in real time and remotely. 2. Description of Prior Art [0003] Industrial facilities used for production and/or processing include equipment that is periodically brought out of service for repair or maintenance. Some of this equipment, such as vessels, reactors, drums, columns, towers, and heat exchangers, have internal confined spaces that are not in communication with ambient surroundings. The equipment is usually vented with a forced vacuum causing ambient air to enter the confined spaced when the repair or maintenance involves personnel accessing inside the confined space(s). Venting fluid flow is sometimes quantified in terms of air changes per hour, which equals the volumetric flow rate of air divided by the confined space volume, safety regulations sometimes dictate the change out values. [0004] In one type of venting, a collector system having a fan or blower draws air from within the confined space through ducting, that sometimes has multiple legs strategically located in the 1 SUBSTITUTE SHEET (RULE 26) confined space. The air pulled from within the confined space is usually replaced with ambient air drawn into the confined space, usually through a manway or other opening in a side of the equipment. A filter in the collector system upstream of the collector blower captures particulate matter (e.g.. dust, catalyst, welding debris, etc.) entrained in the venting fluid exiting the confined space. Currently, venting fluid flowrate through the ducting is measured manually with handheld devices. As inadequate flow of venting fluid can create a hazardous situation inside a confined space, a need exists for continuous monitoring of venting fluid flowrate. SUMMARY OF THE INVENTION [0005] Disclosed is an example of a method of venting that includes transporting a ventilation system to where a confined space is located, where the ventilation system includes a line, a filter in the line, and a blower. The method also includes providing communication between the confined space and an upstream end of the line, providing communication between an inlet of the blower and a downstream end of the line, drawing air from within the confined space by activating the blower to create a flow of air through the line, sensing a characteristic of the flow of air within the line, transmitting data representing the characteristic of the flow of air to a monitoring location that is remote from the confined space, and transporting the ventilation system to where another confined space is located and repeating the steps of venting, sensing, and transmitting data. The ventilation system optionally includes a monitoring unit, and the method further involves transporting the monitoring unit inside of a transportation unit, the transportation unit having a joist on which the monitoring unit is supported, and a pivoting plate that is hingedly affixed to the joist; in this example the monitoring unit is part of a unit package and the method further includes securing the monitoring unit within the transportation unit by pivoting the pivoting plate into coupling engagement with a lower surface of the unit package. Further in this optional example, a magnet is on the lower surface of the unit package, and where the pivoting plate is made up of a ferromagnetic material, so that the pivoting plate is coupled with the monitoring unit by a magnetic attraction between the magnet and the ferromagnetic material. In an embodiment, the method further includes monitoring the data at the remote location, and optionally the monitored data is one or both of pressure of air in the line and a flowrate of air in the line. In an alternative, a characteristic of the flow of air is manually sensed within the line. The method optionally includes identifying a blockage of the flow of air to the blower based on the step of manual sensing. Examples of the method include identifying corrective action based on the monitored data, where the corrective action is to change a section of the line, replace a cartridge in the filter, or both. In examples, the data being monitored represents a characteristic of another flow of air in a different line. [0006] Also disclosed is a system for venting, where the system includes a collector blower having a suction and a discharge, a suction line having an end connected to the suction and an opposite end in a confined space, a filter in the suction line, sensor taps in the suction line, a monitoring unit with a transducer in communication with the sensor taps and in wirel
