Portable oil-drilling waste recovery system

Portable waste fluid containment and recovery apparatus for installation in-line with a piping system between a pair of horizontal interfacing flanges thereof comprising:

• a) a pan having a bottom and surrounding sidewalls, said bottom having a bore therethrough and being sloped downward from adjacent said sidewalls towards said bore;
• b) flange interface means having a pair of opposed interfacing surfaces which interface with respective ones of the pair of interfacing flanges disposed around said bore for sealably connecting said bottom in line with the piping system;
• c) a drain pipe connected through said bottom adjacent said bore;
• d) a horizontal grating floor disposed over said bottom whereby personnel can walk on said grating floor and waste fluids can pass through said grating floor to said bottom;
• e) a base carrying and supporting said bottom;
• f) a pair of wheels removably carried by said base;
• and,
• g) a pulling tongue removably carried by said base whereby said base with said bottom in combination are pulled as a trailer behind a vehicle to a site for use and then said pair of wheels and said pulling tongue are removed to allow said bottom to be positioned in-line with a piping system.

Supported and vertically adjustable waste fluid containment and recovery apparatus for installation in-line with a piping system between a pair of horizontal interfacing flanges thereof comprising:

• a) a pan having a bottom and surrounding sidewalls, said bottom having a bore therethrough and being sloped downward from adjacent said sidewalls towards said bore;
• b) flange interface means having a pair of opposed interfacing surfaces which interface with respective ones of the pair of interfacing flanges disposed around said bore for sealably connecting said bottom in line with the piping system;
• c) a drain pipe connected through said bottom adjacent said bore;
• d) a horizontal grating floor disposed over said bottom whereby personnel can walk on said grating floor and waste fluids can pass through said grating floor to said bottom;
• e) a plurality of guide members carried by said bottom at spaced intervals about a periphery thereof;
• f) a plurality of vertical support members removably connected to respective ones of said guide members;
• and,
• g) locking adjustment means for releasably and adjustably attaching said plurality of guide members to respective ones of said plurality of vertical support members at selected vertical heights.
