Buying a Diesel Paraffin Removal Truck
If you're in the oil and gas industry, you've probably dealt with paraffin problems. Paraffin — also called wax — builds up in the tubing and the wellbore, and it reduces production. Eventually, it can plug the well completely. A diesel paraffin removal truck — also called a hot oil truck or a paraffin truck — is the equipment you use to fix this. If you're shopping for one, here's what you need to know.
What Does a Paraffin Removal Truck Do?
A paraffin removal truck has one main job: heat up oil or diesel, pump it down the well, and melt the paraffin. It works like this:
- The truck carries a tank of oil or diesel.
- It has a heating system — usually a heat exchanger or a boiler — that heats the fluid up to 150-200°C.
- The hot fluid is pumped down the well, through the tubing.
- The hot fluid melts the paraffin that's built up in the tubing and the wellbore.
- The melted paraffin comes back up with the fluid, and the well flows normally again.
Paraffin removal is a regular maintenance operation. In many oil fields, you have to do paraffin removal every few weeks or months, depending on the crude oil and the well temperature. If you don't do it, production will decline, and eventually the well will plug.
What to Look For When Buying a Paraffin Removal Truck
Heating Capacity. How hot can the truck heat the fluid? Paraffin melts at different temperatures, depending on the type of paraffin. You need a truck that can heat the fluid hot enough to melt the paraffin in your wells. Most paraffin trucks can heat to 150-200°C, which is enough for most wells.
Tank Size. How big a tank do you need? Paraffin removal jobs use a lot of hot fluid — usually 50-200 barrels per job. You need a tank big enough to hold enough fluid for the job, plus a buffer. Most paraffin trucks have 5,000-15,000 liter tanks.
Pumping Capacity. What's the pump rate? You need a pump that can pump the hot fluid down the well at the right rate and pressure. Most paraffin trucks have pumps that can deliver 10-50 barrels per minute at 500-1,500 psi.
Truck Chassis. What kind of truck chassis do you need? If you're driving on paved roads, a 4x2 truck is enough. If you're driving on rough oilfield roads, you need a 4x4 or 6x6 truck, with good off-road capability.
New vs. Used
Buy New If: You're starting a new operation, you need a warranty, or you want the latest features. New paraffin removal trucks come with factory support, and you know exactly what you're getting. But they're expensive.
Buy Used If: You're on a tight budget, or you just need a truck that works. Used paraffin removal trucks are 40-60% cheaper than new. But you have to inspect them carefully — check the heating system, check the pump, check the tank for rust, and check the truck chassis. Bring a mechanic with you to inspect any used truck before you buy.
FAQ
Q: How much does a diesel paraffin removal truck cost?
A: A new paraffin removal truck costs $150,000 to $400,000, depending on the size and features. A small 5,000-liter truck starts around $150,000. A big 15,000-liter truck can cost $400,000 or more. Used trucks are 40-60% cheaper.
