## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 3)

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.

### Claim 5 (depends on 4)

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.

### Claim 6 (depends on 4)

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.

### Claim 7 (depends on 4)

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.

### Claim 8 (depends on 7)

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.

### Claim 9 (depends on 4)

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.

### Claim 10 (depends on 4)
