Abstract

A modularized system for conditioning liquid fuel is provided that includes a mobile trailer and a liquid fuel conditioning skid disposed on and secured to the mobile trailer. The modularized system includes a pre-filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a pre-filter configured to remove impurities from a processed liquid fuel prior to providing the processed liquid fuel to a last chance filter. The modularized system includes a last chance filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a last chance filter configured to remove impurities from the processed liquid fuel prior to providing the processed liquid fuel to a gas turbine engine. The pre-filter sub-skid and the last chance filter sub-skid are coupled together via piping enabling flow the processed liquid fuel between the pre-filter sub-skid and the last chance filter sub-skid.

First claim

The invention claimed is:

1. A modularized system for conditioning liquid fuel, comprising:
a mobile trailer;
a liquid fuel conditioning skid disposed on and secured to the mobile trailer;
a pre-filter sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the pre-filter sub-skid comprises a pre-filter configured to remove impurities from a processed liquid fuel prior to providing the processed liquid fuel to a last chance filter; and
a last chance filter sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the last chance filter sub-skid is separate from the pre-filter sub-skid, and wherein the last chance filter sub-skid comprises a last chance filter configured to remove second impurities from the processed liquid fuel received from the pre-filter sub-skid prior to providing the processed liquid fuel to a gas turbine engine of a power plant;
wherein the pre-filter sub-skid and the last chance filter sub-skid are coupled together via a first set of piping enabling flow of the processed liquid fuel between the pre-filter sub-skid and the last chance filter sub-skid, and wherein the last chance filter sub-skid and the pre-filter sub-skid are separate from the liquid fuel conditioning skid.

2. The modularized system of claim 1 , comprising a forwarding sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the forwarding sub-skid comprises at least one pump configured to receive the processed liquid fuel from a buffer tank and to provide the processed liquid fuel to the pre-filter, wherein the forwarding sub-skid and the pre-filter sub-skid are coupled together via a second set of piping enabling flow of the processed liquid fuel between the forwarding sub-skid and the pre-filter sub-skid.

3. The modularized system of claim 2 , comprising a centrifuge sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the centrifuge sub-skid comprises a centrifuge configured to receive a raw liquid fuel, to remove third impurities from the raw liquid fuel to generate the processed liquid fuel, and to provide the processed liquid fuel to the buffer tank.

4. The modularized system of claim 3 , comprising a water tank sub-skid disposed on and secured to the mobile trailer, wherein the water tank sub-skid comprises a water tank and a pump configured to provide water to the centrifuge to flush the centrifuge of sludge, wherein the water tank sub-skid and the centrifuge sub-skid are coupled together via a third set of piping enabling flow of the water between the water tank sub-skid and the centrifuge sub-skid.

5. The modularized system of claim 4 , wherein the mobile trailer is configured to transport the liquid fuel conditioning skid while the pre-filter sub-skid, the last chance filter sub-skid, the forwarding sub-skid, the centrifuge sub-skid, and the water tank sub-skid are disposed on and secured to the liquid fuel conditioning skid.

6. The modularized system of claim 4 , wherein the liquid fuel conditioning skid is configured to be removed from the mobile trailer while the pre-filter sub-skid, the last chance filter sub-skid, the forwarding sub-skid, the centrifuge sub-skid, and the water tank sub-skid are disposed on and secured to the liquid fuel conditioning skid.

7. The modularized system of claim 4 , wherein at least one of the pre-filter sub-skid, the last chance filter sub-skid, the forwarding sub-skid, and the centrifuge sub-skid is configured to be removed from the liquid fuel conditioning skid.

8. The modularized system of claim 7 , wherein each of the pre-filter sub-skid, the last chance filter sub-skid, the forwarding sub-skid, and the centrifuge sub-skid is configured to be removed from the liquid fuel conditioning skid.

9. The modularized system of claim 4 , wherein interconnect piping between the pre-filter sub-skid, the last chance filter sub-skid, the forwarding sub-skid, the centrifuge sub-skid, and the water tank sub-skid is coupled together and flushed prior both to transport of the modularized system to the power plant and to coupling of the modularized system to the power plant.

10. The modularized system of claim 4 , comprising electrical circuitry for a grounding system, and the electrical circuitry for the grounding system is already completed for the modularized system prior both to transport of the modularized system to the power plant and to coupling of the modularized system to the power plant.

11. The modularized system of claim 10 , comprising a single electrical interface for electrically coupling the modularized system to the power plant.

12. The modularized system of claim 4 , comprising a controller coupled to the centrifuge sub-skid and configured to execute instructions to control components of the liquid fuel conditioning skid to condition the liquid fuel for the power plant, wherein the controller is configured to be integrated within a distributed control system of the power plant.

13. A modularized system for conditioning liquid fuel, comprising:
a mobile trailer;
a liquid fuel conditioning skid disposed on and secured to the mobile trailer;
a pre-filter sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the pre-filter sub-skid comprises a pre-filter configured to remove impurities from a processed liquid fuel prior to providing the processed liquid fuel to a last chance filter;
a last chance filter sub-skid disposed on and secured to the liquid fuel conditioning skid, wherein the last chance filter sub-skid is separate from the pre-filter sub-skid, and wherein the last chance filter sub-skid comprises the last chance filter configured to remove second impurities from the processed liquid fuel received from the pre-filter sub-skid prior to providing the processed liquid fuel to a gas turbine engine of a power plant, and wherein the last chance filter sub-skid and the pre-filter sub-skid are separate from the liquid fuel conditioning skid;
electrical circuitry for a grounding system, wherein the electrical circuitry for the grounding system is already completed for the modularized system prior both to transport of the modularized system to the power plant and to coupling of the modularized system to the power plant; and
interconnect piping coupling together the pre-filter sub-skid and the last chance filter sub-skid enabling flow of the processed liquid fuel between the pre-filter sub-skid and the last chance filter sub-skid, wherein the interconnect piping is coupled to the pre-filter sub-skid and the last chance filter sub-skid and flushed prior both to transport of the modularized system to the power plant and to coupling of the modularized system to the power plant.
