Abstract
An apparatus for redirecting fluid at a flanged connection is disclosed. The apparatus comprises a flattened section and a tubular section. The flattened section is suitable for insertion between two adjacent flanges of the flanged connection and the tubular section is suitable for attachment to a conduit such as a hose or pipe. The flattened section has a front face, a rear face and an inlet on the front face. The tubular section has an outlet and the interior of the flattened section is in fluid communication with the interior of the tubular section. The flattened section is sufficiently thin to allow the flanged connection to be reassembled, with the apparatus installed, without redesign or dismantling of any related piping.
Description
"STEAMOUT EFFLUENT CATCHMENT BLIND FOR TANKS
AND PRESSURE TANKS"
FIELD OF THE INVENTION
This invention relates generally to catchment devices and clean-out blinds and, more particularly, to devices for installation or insertion between flanges or flanged sections of pipe to facilitate catching and redirecting steam and water effluent.
BACKGROUND OF THE INVENTION
During clean-up times or turn-arounds at refineries, petrochemical and other oil-and-gas facilities, when typically dozens of pressure vessels in a plant are purged and cleaned with steam, clean-up crews often unbolt flanged sections of piping to provide an exit for the steam and water that has gone through a pressure vessel and piping as part of the clean-out process. It is not uncommon for the clean-up crews to simply let the steam escape into the atmosphere and allow the water run onto the ground or floor.
One problem with this is that the steam vapour and water effluent will be contaminated with whatever was inside the pressure vessel or piping.
Contaminants may include hydrocarbons, H2S or carcinogenic substances; and would thus be released to the surroundings, creating environmental and safety concerns.
A further problem is that the piping between the various pressure vessels is often fixed in place. It is therefore difficult to remove a section of pipe to attach a vacuum hose or other containment means. It is simply easier to unbolt flanged sections of pipe, and perhaps slide one relative to another, thereby creating an opening for the steam and water to exit. This has worked because all that typically exits during a clean-out of a plant or pressure vessel is the contaminated steam and water, requiring only a relatively small opening or crack.
Applicant is not aware of any device, suitable for catching and redirecting steam and water effluent during clean-outs and turn-arounds at refineries, petrochemical and other oil-and-gas facilities that is simple to operate, and can be easily and inexpensively manufactured and is installed between flanges in a straightforward manner.
SUMMARY OF THE INVENTION
The invention provides an apparatus for redirecting fluid at a flanged connection. In one aspect the apparatus comprises a flattened or narrowed section suitable for insertion between two adjacent flanges of the flanged connection, said flattened section having a front face, a rear face and an inlet on the front face. The apparatus further comprises a tubular section suitable for attachment to a conduit, said tubular section having an outlet. The interior of the flattened section is in communication with the interior of the tubular section enabling efFluent, which enters the intlet, to move from the flattened section to the tubular section and out the outlet.
