3-D high-pressure cleaning tool used on reactor

Problem: An industrial facility in Delaware faced production problems due to severe fouling of a horizontal reactor, with buildup predominantly on the agitator shaft, blades and reactor ends. The company attempted two different manual cleaning methods ­– a sharp metal rod and a high-pressure lance. Both methods were only able to remove chunks of residue in the line of sight of the operator, leaving a large amount of residue on the vessel’s walls and blades. A safer, faster, more efficient solution was required.       

Solution: Chemac Inc. was invited to conduct a demonstration using a URACA 3-D TWK 175/800 high-pressure cleaning tool. The tool had an operational pressure of approximately 10,000 psi and a flow rate of 40 gpm. It was fitted on a high-pressure pipe and positioned inside the vessel with a special flange adapter. The operator only needed to position the tool, lock the agitator and turn on the pump.

Result: The tool successfully removed all buildup from the reactor in minutes. All residues were removed to the complete satisfaction of plant management. All cleaning was done with minimal labor, mitigating previous safety concerns. 800/217-8677; www.chemacinc.com.

Pneumatic cutter renews pipe system

Problem: The high-volume drainage line, which takes in all other drainlines for the aqua-theatre inside Hersheypark in Hershey, Pa., was experiencing inadequate flow, backups and corrosion.

Solution: Jet Tec Inc. mechanically cleaned the 4-inch-diameter cast iron pipe system, located 15 to 28 feet underground, with the Pneumatic Micro-Cutter from Nu Flow Technologies. It is used for reinstating and to clean and remove pipe debris, calcite and roots from the inside of a variety of pipes, including steel, cast iron and Orangeburg. The system rotates at 1,500 rpm in 1 1/4- to 6-inch pipes in lengths up to 100 feet, and will negotiate turns of 90 degrees in pipes down to 2 inches in diameter.

Result: The cutter allowed Jet Tec. Inc. to remove corrosion and bring the interior of the pipe back to the original diameter, without causing any failure or breach to the already-damaged pipes. After cleaning the line, a Nu Drain structural liner was installed. 905/433-5510; www.nuflowtech.com.
