Abstract
A gas seal column apparatus includes a vertically-oriented column, a pump, an inlet pipe, a an outlet pipe, and a drive shaft driven by any type of motor. The pump and the gas seal column comprise a vertically-oriented pump system. The inlet pipe receives pressurized seal gas for introducing the seal gas into the pump system. The outlet pipe enables the seal gas to exit the pump system. The drive shaft is encased by the gas seal column between the pump drive motor and the pump to couple the pump drive motor to the pump.
Claims33
A gas seal column apparatus comprising:
- a vertically-oriented pump envelope including a gas seal column and a pump;
- a pump drive motor configured to drive the pump envelope, the pump envelope and the pump drive motor configured to be sealed together;
- a drive shaft encased by the pump envelope between the pump drive motor and the pump to couple the pump drive motor to the pump;
- an inlet pipe configured to receive pressurized seal gas for introducing the seal gas into the pump envelope;
- a discharge valve configured to enable the seal gas to exit the pump envelope;
- and
- a control box, wherein when the pump drive motor is in a standby mode, the control box is configured to enable an amount of product in the gas seal column to increase to a predetermined threshold, the control box further configured to selectively enable gas pressure within the gas seal column to increase when the amount of product reaches the predetermined threshold to limit the amount of product in the gas seal column.

A gas seal column apparatus, comprising:
- a pump drive motor includes an off mode, a standby mode, and an operating mode;
- a gas seal column configured to receive a seal gas for pressurizing the gas seal column;
- a vertically-oriented pump system comprising a pump and the gas seal column, coupled to the pump drive motor and configured to move a product through the pump;
- a plurality of level sensors to detect a level of the product in the gas seal column and any fumes in the gas seal column;
- and
- a control box in communication with the plurality of level sensors, the control box configured to control an amount of the seal gas received within the gas seal column to control an amount of fumes within the gas seal column and the level of the product within the gas seal column when the pump drive motor is in a standby mode.
3 more elements
A gas seal column apparatus, comprising:
- a pump drive motor and a sealed pump envelope, further comprising a gas seal column and a pump;
- said pump drive motor having an extended shaft suitable to drive said pump;
- where said pump drive motor and a gas shaft seal are attached to the gas seal column;
- where the gas seal column encasing said extended shaft creates a gas-tight seal to comprise a sealed, vertically-oriented, pumping system;
- where the pump drive motor is connected to said sealed pump envelope;
- where a pressurized gas that is introduced into the gas seal column becomes seal gas;
- where the seal gas exits the gas seal column;
- where a plurality of level sensors to detect a level of product and any fumes in the gas seal column;
- where a seal gas control box utilizes said level sensors to control the level and displacement of said product and any fumes within the gas seal column;
- and
- a control box, wherein when the pump drive motor is in a standby mode, the control box is configured to enable an amount of product in the gas seal column to increase to a predetermined level, the control box further configured to enable gas pressure within the gas seal column to increase when the amount of product reaches the predetermined level to limit the amount of product in the gas seal column.
8 more elements
A gas seal column apparatus comprising:
- a vertical gas seal column configured to encase a vertical drive shaft;
- a pump drive motor;
- a gas inlet pipe configured to receive pressurized seal gas and introduce the pressurized seal gas into the vertical gas seal column;
- a gas discharge valve configured to enable the pressurized seal gas to exit the vertical gas seal column;
- and
- a control box configured to control an amount of the pressurized seal gas received within the vertical gas seal column to enable an amount of a product within the vertical gas seal column to selectively increase and decrease when the pump drive motor is in a standby mode.
