Crude Oil Dispatch Pump: A Comprehensive

Overview

Crude oil Dispatch Pump

INTRODUCTION

Crude oil dispatch pumps are used in the oil and gas industry to transport crude oil and gas from one location to another location through pipelines such as from wellhead to storage tank, from storage tank to group gathering station (GGS), from group gathering station (GGS) to oil storage tank (OST), from the group gathering station (GGS) to the central processing facility (CTF) and from the central processing facility (CTF) to the refineries.Crude oil dispatch pumps are specialized pumps designed to efficiently transfer crude oil from storage tanks to trucks, pipelines, or refineries. These pumps are crucial components in the oil and gas industry, as they keep the crude oil moving throughout the transportation process.

These pumps are used to overcome pressure and flow rate losses as the oil flows through the production system.These pumps are specifically designed to handle the thick, viscous nature of crude oil, efficiently transferring it from storage tanks to trucks, pipelines, or refineries.This pump controls the pressure and flow rate as the oil flows through the production system to prevent damage to the system.

Crude Oil Dispatch Pumps can be Classified Into Two Main Types:

• Positive Displacement Pumps 

• Centrifugal Pumps.

(1) Positive Displacement Pumps:

These pumps use a fixed volume to move the fluid through the pump. Examples of positive displacement pumps used for crude oil dispatch include reciprocating pumps and progressive cavity pumps. They are commonly used in low flow rate or high viscosity crude oil applications.These pumps use a closed chamber to trap and move a fixed amount of fluid with each cycle. Common types of positive displacement pumps used for crude oil dispatch include:

• Reciprocating pumps: These pumps use a piston or plunger that moves back and forth in a cylinder to create suction and discharge oil.

• Rotary Gear or Vanes pumps: These pumps use rotating gears or vanes to move oil through the system. They are generally more compact and lighter than reciprocating pumps or These pumps use two intermeshing gears that rotate within a housing to move the oil.

• Screw pumps: These pumps use one or more helical screws that rotate within a chamber to move the oil,These pumps use a set of intermeshing screws to move oil through the system. They are efficient and can handle high viscosities.

(2) Centrifugal Pumps: 

These pumps use a rotating impeller to convert kinetic energy into hydraulic energy to move the oil. Centrifugal pumps are generally less common for crude oil dispatch applications due to the high viscosity of crude oil, but they can be used for thinner crude oils or when very high flow rates are required.

• These pumps are commonly used in oil dispatch operations due to their ability to handle high flow rates and low viscosity fluids. They work by using a rotating impeller to create a centrifugal force that propels the liquid through the pump.

• These pumps use centrifugal force to increase the velocity of the oil, which creates pressure to move it through the system. They are generally less efficient for viscous fluids like crude oil, but they can handle high flow rates.

• The selection of the right type of pump depends on the specific requirements of the application, including the flow rate, pressure, and the type of crude oil being pumped. Factors such as cost, maintenance requirements, and the availability of infrastructure must also be considered.

• Crude oil dispatch pumps are critical components of the oil and gas production system, and their reliability and efficiency are essential to ensure the smooth and safe operation of the entire production process. In recent years, technology advancements have allowed for the use of automation, digitalization, and data analysis to improve the performance and reduce downtime of these pumps.

• Oil conveying pumps are used to move crude oil or refined petroleum products from storage tanks to various points of use.
  

Selection Considerations for Crude Oil Dispatch Pumps

When selecting a crude oil dispatch pump, several factors need to be considered, including:

• The viscosity of the crude oil: The viscosity of crude oil can vary depending on its source and temperature. Higher viscosity oils require pumps that can handle thicker fluids.

• The flow rate required: The flow rate is the amount of oil that needs to be transferred per unit of time. The pump must be able to deliver the required flow rate efficiently.

• The discharge pressure required: The discharge pressure is the pressure needed to overcome the pressure drop in the piping system and deliver the oil to its destination.

• The operating temperature: The pump must be able to operate at the temperatures of the crude oil being transferred.

Additional Features of Crude Oil Dispatch Pumps

Crude oil dispatch pumps may also include additional features such as:

• Bypass valves: These valves allow the oil to circulate back to the storage tank if the discharge pressure becomes too high.

• Relief valves: These valves protect the pump from damage by relieving pressure if it exceeds a certain limit.

• Meters: These devices measure the amount of oil that is being transferred.

• Filters: These components remove impurities from the oil before it is transferred.

Importance of Crude Oil Dispatch Pumps

Crude oil dispatch pumps play a vital role in the oil and gas industry by ensuring the efficient and safe transfer of crude oil. They are essential for keeping the global economy running by delivering the crude oil that is refined into gasoline, diesel fuel, and other products.

There are several types of other oil dispatch pumps

Positive displacement and centrifugal pumps are the two main categories, but there are other types of oil dispatch pumps used for specific needs:

• Metering pumps:  These precision pumps deliver a controlled, constant flow rate of oil, ideal for applications requiring accurate measurement during transfer.

• Diaphragm pumps:  These pumps use a flexible diaphragm to move oil, making them suitable for handling abrasive or corrosive oil mixtures without internal contamination.

• Hydrocarbon condensate pumps:  Designed for low viscosity hydrocarbon liquids like condensate, these pumps efficiently transfer them from separators or storage tanks.

• Portable high-pressure pumps:  As the name suggests, these are mobile units ideal for temporary oil transfer needs or emergency situations requiring high pressure.
