oily water drain problem
oily water drain problem
(OP)
I have an existing drain pipe of 4" with slope 0.005 receiving oily water from different equipments of a co2 removement and dewpoint plant. this drainage pipe is buried 1.78 m and is 110 m long. At the end, it climbs again 1.78 m to discharge in a sump tank before it is delivered to the API pool for its treatment.
I dont know the flow rates.
I have to attach to this existing pipe another one collecting the oily water from a new dew point plant with larger capacity, at a distance of 60 m. of the existing pipe.(another option is build a new pipe to the sump)
MY QUESTION IS HOW CAN I DETERMINE IF THE VOLUME DRAINED FROM THE EQUIPMENTS WILL CLIMB THE 1.78 M AND REACH THE SUMP?
HOW CAN I CALCULATE IF THE EXISTING PIPE WILL COPE WITH THE EXTRA VOLUME OF OILY WATER?
I`ve been analysing the thread 25362 and the reference posted by katmar, tables and Manning formula
ANY HELP WOULD BE APPRECIATED, ESPECIALLY POINTERS TO A BOOK OR REFERENCES.
THANKS

RE: oily water drain problem
Check the pipe inverts of the beginning and end of the pipe drain.
RE: oily water drain problem
I´ve checked and the suction of the sump tank has a 2.78 m elevation from the pipe level. (even more)
Maybe it´s a pressurized drainage line, but I have two equipments that are atmospheric, so I´m thinking of joining the new collecting line directly to the sump.
Anyone has another idea?
