Abstract
Process for the control of turbidity currents, especially of high temperature lubricants in the form of graphite and polymers, suspended in water, with a viscosity of 1,000 to 20,000 cP at a temperature of up to 250 bars and a current velocity of up to 120 m/sec. Closing and opening times of 2 to 20 milliseconds are maintained. Apparatus for achieving the process, which is a switching-off valve having closing and opening times of 2 to 20 milliseconds. The switching-off valve preferably is a plunger valve.
Claims5
A process for controlling the flow of high temperature lubricants in the form of graphite and polymers, suspended in water, having a viscosity of 1,000 to 20,000 cp, at a pressure of up to 250 bars and a current velocity of up to 120 m/sec., using a switching-off valve, comprising maintaining closing and opening times of 2 to 20 milliseconds during the operation of said valve.
