Note: Before proceeding with the procedure, proper lineups to / from the tanks and unit must be made. The appropriate drawings must be reviewed and the lineups understood by the Pumpers to ensure that the equipment lineup has been made from the appropriate tank and process area. A list of drawings is included at the end of this procedure.

Date Time Initials

1.______Prepare the tank and the pump.

1.1 Get a gauge and temperature on the tank to be pumped. Record this information in your notebook.

1.2 Open the pump suction valve.

2.______Start the pump.

2.1 Start the pump.

2.2 Open the pump discharge bleeder to the flare line.

2.3 Watch the pump pressure gauge. When the pressure comes up to normal discharge pressure, close the discharge bleeder and gradually crack open the discharge valve, just enough to hold pressure. Normal discharge pressure will vary and experience is the best guide as to how much to open the discharge valve.

2.4 Call the unit operator to verify that he is receiving feed. If he is not, repeat steps 2.0 through 2.3 until flow is verified.

Note: In cold weather, the LPG storage tank pressure may drop to the point where picking up and maintaining pump suction is difficult. If this happens, it may be necessary to put propane vapors over to the tank to raise pressure. Before opening the vapor line between tanks, consult with the Tank Farm Supervisor or Shift Foreman.

2.5 Check the pump and pipelines for leaks or any other abnormalities before leaving the area.

3.______Record the startup.

3.1 Record the startup on the pumpers' "to unit" log sheet. Include the gauge, temperature, and time.

PROCEDURE INFORMATION

PURPOSE: This procedure describes the steps necessary to line up a liquefied petroleum gas (LPG) unit feed pump. Lining up the feed pump is necessary to provide feedstock to the process unit.

PREREQUISITES: A supervisor or unit operator must authorize the startup of a unit feed pump.

RESPONSIBILITY: The Tank Farm Pumper is responsible for starting the unit feed pumps.

MATERIALS AND EQUIPMENT: No special equipment is required.

SAFETY:

Special or Unique Hazards: N/A

Engineering Controls: N/A

Administrative Controls: This procedure is an administrative control to help prevent possible problems.

Personal Protective Equipment (PPE): Normal Tank Farm personal protective equipment must be worn at all times. This includes hard hats, fire retardant clothing and safety glasses. Additional protective equipment may be required per permit requirements.

SAFETY SYSTEMS

Shutdowns: N/A

Relief: N/A

Other Safety: N/A

QUALITY AND INVENTORY

Inventory: Double-check gauges for accuracy to prevent yield calculation errors and to keep tank levels within safe limits.

Quality: The unit feed should be of normal quality to prevent potential unit problems and or unit product specification problems.

OPERATING LIMITS:

Description / Limits / Consequences of Deviation / Corrective and Avoidance Steps
Tank Level / Depends on particular tank and pump. / Pump will cavitate and can be damaged. May result in LPG being released and possible fire. / Ensure that sufficient product is in tank to prevent pump cavitation.

CHEMICAL SAFETY:

General information is provided here. Additional information is available from the MSDS sheet for the specific material in question. /

LPG:
Propane
Propylene
Butane

Isobutane / Flammable materials
LPG is a vapor at atmospheric temperature and pressure / Hot fumes or mists can be irritating to the skin eyes and respiratory tract and can cause drowsiness, headache, and nausea. Overexposure to vapors can lead to unconsciousness or convulsions, bronchopneumonia, and even brief inhalations of high concentrations can cause fatal pulmonary edema.
LPG Liquid causes freeze burns upon contact to skin or eyes.
Hydrocarbon vapors can burn or explode on contact with a source of ignition in the presence of air or oxygen. / In case of skin contact with liquid LPG immediately wash with tepid water. If freezing burns have occurred, apply bulky, dry, sterile bandage and get medical attention.
In case of eye contact, immediately flush eyes with water for 15 minutes including under the eyelids, and see a physician.
If swallowed see a physician, do not induce vomiting.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. See a physician
