Abstract
Methods and apparatus are provided for influencing mixing of a first fluid injected through a slot into a second fluid flowing through a conduit, by automatically or remotely adjusting the slot width to provide at least a certain slot velocity of the first fluid being introduced into the conduit. In particular, methods and apparatus are provided for mixing control in injecting titanium tetrachloride into an oxygen stream in a process for making titanium dioxide.
Claims21
A method for mixing two fluids, comprising the steps of:
- introducing a first fluid through a circumferential injection slot and into a conduit transporting a second fluid, wherein the circumferential injection slot is defined by a moveable wall that is transversely movable relative to the introduction of the first fluid therethrough;
- and
- automatically or remotely adjusting the circumferential injection slot, by transversely moving the moveable wall so as to adjust the width of the circumferential injection slot to maintain at least a certain slot velocity of the first fluid through the circumferential injection slot.
A method for mixing two fluids, comprising the steps of:
- introducing, at a first pressure, a first fluid through a circumferential injection slot and into a conduit transporting a second fluid, wherein the circumferential injection slot is defined by a moveable wall that is transversely movable relative to the introduction of the first fluid therethrough;
- monitoring the first pressure;
- and
- automatically or remotely adjusting the circumferential injection slot in accordance with the monitored first pressure by transversely moving the moveable wall so as to adjust the width of the circumferential injection slot.
A method for mixing two fluids, comprising the steps of:
- introducing, at a first flow rate and a first pressure, a first fluid through a circumferential injection slot and into a conduit transporting a second fluid, wherein the circumferential injection slot is defined by a moveable wall that is transversely movable relative to the introduction of the first fluid therethrough;
- monitoring the first flow rate;
- and
- automatically or remotely adjusting the size of the circumferential injection slot in accordance with the monitored first flow rate by transversely moving the moveable wall so as to adjust the width of the circumferential injection slot.
A method for adjusting a circumferential injection slot in an apparatus for injecting a first fluid into a conduit transporting a second fluid, the circumferential injection slot defined by a moveable wall that is transversely moveable relative to the injection of the first fluid therethrough, comprising the step of:
- automatically or remotely adjusting the circumferential injection slot to maintain a substantially constant slot velocity by transversely moving the moveable wall so as to adjust the width of the circumferential injection slot.
A method for mixing two fluids, comprising the steps of:
- introducing a first fluid through a circumferential injection slot and into a conduit transporting a second fluid, wherein the circumferential injection slot is defined by a moveable wall that is transversely movable relative to the introduction of the first fluid therethrough;
- and
- automatically adjusting the circumferential injection slot, by transversely moving the moveable wall so as to adjust the width of the circumferential injection slot to maintain at least a substantially constant slot velocity of the first fluid through the circumferential injection slot and maintain a substantially constant pressure drop across the circumferential injection slot and so that the introducing step is preformed at a substantially constant pressure wherein a bellows is utilized to maintain the substantially constant pressure of the introducing step and the bellows has a side attached to the movable wall.
