Abstract: A method for cleaning tubes and heat exchangers as set forth. The method and apparatus involve an elongate lance which is mounted to move in an X and Y pattern to align with a set of tubes. Each tube is cleaned by positioning the lance at the end of each tube to be cleaned. A plug is placed in the tube to be cleaned to form a standing column for water. By means of a valve control system, the standing column of water is cycled from low to high pressure by switching the flow of water. In this switched mode, water is delivered under pressure into the column. The lance tip functions in conjunction with an orifice upstream of the lance tip to form a shock wave of energy radiating along the standing column of water from the orifice into the tube to be cleaned. The addition of water to the tube ultimately moves the plug along the length of the tube. It is one theory of operation of the present disclosure that the column of water exposed to shock waves is used in cleaning, i.e., shock waves do the cleaning while the addition of water merely provides sufficient water to form the standing column of water in the tube.

Abstract: An apparatus for monitoring current for a motor drive including at least high-side and low-side switching transistors includes a driver circuit for driving a gate of the low-side switching transistor. First circuitry measures a drain to source voltage across the low-side switching transistor and generates a voltage output responsive thereto. Second circuitry has a first state of operation that samples the voltage output of the first circuitry when the low-side switching transistor is turned on and has a second state of operation to sample the voltage output of the first circuitry when the low-side switching transistor is turned off. The second circuitry further generates a monitored output current responsive to the sampled voltage output.

Abstract: A method for cleaning tubes and heat exchangers provides a cavitation enhancement unit between a source of pressurized fluid an a lance. The pressurized fluid flows through jets, which impart a high speed rotation to a set of propellers, preferably square in profile canted at a 15° angle. Generation of cavitation develops a cleaning vibration in the fluid discharged from the lance.

Abstract: A method for cleaning tubes and heat exchangers provides an oscillating pump/valve mechanism to provide a periodic waveform of shocks to fouled tubes. Preferably, a pair of pneumatic control valves operates an actuator to oscillate a valve within a valve block, and isolation of a fluid within a manifold in the block creates a pumping action from the valve, to create an intense fluid shock wave to clean interior surfaces tubes.

Abstract: An aqueous dispersion of unreacted particulate petroleum coke substantially comprising carbon and containing a small amount of ash substantially comprising vanadium constituents and other materials from a process for the partial oxidation of petroleum coke to produce synthesis gas is mixed with C.sub.4 to C.sub.8 acyclic and/or cyclic alkanols and a frothing agent. After pH adjustment, if necessary, the mixture is subjected to aeration with or without mechanical agitation in a froth flotation zone. About 60 to 95 wt. % of the unconverted particulate petroleum coke (basis carbon) particles float in the froth layer that is formed. The remainder of the unconverted petroleum coke comprising coarser particles is suspended in a bottom aqueous dispersion on which the froth layer floats. In addition, selective separation of the vanadium constituents in the unconverted petroleum coke ash takes place. The vanadium content of the ash in the floated portion of unconverted petroleum coke is unexpectedly decreased about 40 to 80 weight percent. Simultaneously, the vanadium content of the ash in the unconverted petroleum coke suspended in the bottom layer of aqueous dispersion is unexpectedly increased about 20 to 60 weight percent. Water may be recovered from this aqueous dispersion and recycled to the gas quench cooling and scrubbing zones. At least portions of the unconverted particulate petroleum coke from the foam layer and the bottom layer are recycled to the partial oxidation gas generator and to a vanadium recovery zone, respectively. By the subject process, the vanadium content in the recycle stream of unconverted petroleum coke to the gas generator is reduced. The life of the refractory lining of the gas generator is thereby extended.
