Abstract
A system for maintaining a stable pressure in a process analyzer measurement cell using pneumatic components. The system comprises an eductor having a pressure passage, a discharge passage, and a suction passage, and an eductor flow regulator for regulating the flow of a motive gas to the pressure passage as a function of pressure in the suction passage or the discharge passage.
Claims12
A system for maintaining pressure in a vent header when venting one or more process gases comprising an eductor having a pressure passage for receiving a motive gas, a discharge passage, a flow constrictor between the pressure passage and the discharge passage for speeding the flow of fluid past a suction opening, and a suction passage for connecting the suction opening to the vent header;
- and an eductor flow regulator for regulating the flow of the motive gas to the pressure passage as a function of pressure in the suction passage or the discharge passage.
A method for maintaining pressure in a vent header when venting one or more process gases using an eductor having a pressure passage for receiving a motive gas, a discharge passage, a flow constrictor between the pressure passage and the discharge passage for speeding the flow of fluid past a suction opening, and a suction passage for connecting the suction opening to the vent header, the method comprising the step of regulating the flow of the motive gas to the pressure passage as a function of pressure in the suction passage or the discharge passage.
