Chemical injection quills from Crystal Industrial

I’d like to tell you about the chemical injection quill, which is a less-common product in the industry, to help users make good plans and technical evaluations.

What is a chemical injection quill?
Chemical injection quill is a piece of machinery used in the chemical injection process, which is used in many different industries. It is a piece of equipment that connects the chemical supply line to the process pipeline. The chemicals that are injected are controlled to cause a chemical reaction, and the quill helps to spread these chemicals through the process pipeline.

Types of applications
Chemical injection is used for many things, like adding additives, treatment with chemicals or biological fluids, and removing or separating things. Here are some examples of chemicals that are used in the process of oil/gas injection:

Methanol
Used to stop hydrates from forming. When hydrate solidifies, it can slow down or stop the flow in wells and flowlines.

Corrosion inhibitors
Used to stop corrosion from happening in wells and pipelines, which cuts down on downtime.

H2S scavenger
Used to treat oil and gas by lowering the amount of H2S to protect health and stop corrosion.

The injection quill could have different shapes, connections, and fittings, such as: From a simple custom-built tube/probe to a single unit with isolation valves and valves that don’t let fluid back in. As part of what we do best, we make an unified chemical injection quill with a probe, double block & bleed assembly ( and 2 isolation valves), and an integral non-return check valve, all in one tight assembly.

This type of quill is attached to the pipeline through a fitting so that the quill or probe can be inserted and reach the middle of the process line. The other end is connected to the chemical feed line by pipes or tubes that go all the way back to the chemical injection skid or chemical Dosing package, which holds the pump and chemical tank.

While an injection quill is designed, the following points must be taken into account:

Design calculation
The wake frequency is calculated using the standard ASME PTC 19.3 TW-2010 for Thermowell, since the quill is very comparable to it. Since the design has to take into account both temperature and stress, the customer should give the necessary process data (fluid, temperature, pressure, velocity, flow rate, density, viscosity). If the calculation isn’t good enough, you can also use a support collar to get a great outcome. A poorly made quill can break quickly and need to be replaced.

Material
The grade of the material should be right for both the service and the type of chemical that will be injected. Since the quill, DBB, and check valve are all part of the same assembly, you need to look at several parameters just like you would for an isolation valve. This includes the body of the valve and its trim, whether it has a soft seat or a metal seat, etc. A bad choice of material grade is the cause of many mechanical problems.

Isolation is safe
There are designs for quills that don’t have an isolation valve built in or that only have a single isolation. In some applications and media, a DBB valve that is built in is important to improve safety. So it is with the Injection Quill, which is installed in API 6A wellheads with a pressure rating of 10,000 psi. When talking about safety, the way the valve seals and how much it leaks are very important. We have a routine customer for injection quills who needs API PSL 3G PR2 because the gas service is very sour. This testing and quality standard is very unique and not something that all manufacturers can meet.

Dimension
The length of the quill is one of the most important things to know when figuring out the wake frequency. Most of the time, the length is made as per custom choice. Most of the time, the chemical is spread out well when the nozzles are in the middle of the pipeline.

Nozzles
The usual tubes or nozzles are used as the standard for the injection quill. But some applications or users need nozzles that are specially made for better atomization.

Options for mounting
There are different ways to mount it. It could be welded, threaded or flanged, depending on the design, but we must make sure that the outside diameter (OD) of the quill or probe will fit all the way down to the process stream. In one case, the outside diameter (O.D.) of the quill or probe did not fit because the welding penetration took into account the small tolerances. Also, threaded connections are usually not the best choice for very high pressure.

Injection quills and their applications?

Injection quills are used in the oil and gas industry to inject fluids into pipelines for a variety of purposes. These purposes include corrosion control, scale inhibition, and enhanced oil recovery. Injection quills are typically made of corrosion-resistant materials such as stainless steel or plastic and are designed to be inserted into the pipeline through a fitting called a spool piece. The quill has one or more openings through which the fluid can be injected, and the rate of injection can be controlled using valves or other flow control devices. Injection quills are used in both onshore and offshore oil and gas operations and are an important tool for maintaining the integrity and efficiency of pipelines.

One common application of injection quills in the oil and gas industry is corrosion control. Corrosion is a natural process that occurs when metal pipelines are exposed to the elements, such as water, oxygen, and acidic or basic fluids. Corrosion can weaken the pipeline and create leaks, which can be dangerous and costly. To prevent corrosion, oil and gas companies may inject corrosion inhibitors into the pipeline using injection quills. These inhibitors form a protective layer on the metal surface, preventing the corrosion process from occurring.

Another application of injection quills in the oil and gas industry is scale inhibition. Scale is a buildup of minerals and other substances on the inside of pipelines, which can occur when water is present. Scale can restrict the flow of fluids through the pipeline and cause it to become less efficient. To prevent scale buildup, oil and gas companies may inject scale inhibitors into the pipeline using injection quills. These inhibitors prevent the minerals from sticking to the surface of the pipeline, keeping it clean and unobstructed.

Injection quills are also used in the oil and gas industry for enhanced oil recovery (EOR). EOR is a process that involves injecting fluids into an oil reservoir to increase the amount of oil that can be extracted. There are several types of fluids that can be used for EOR, including water, steam, and gases such as carbon dioxide. Injection quills are used to inject these fluids into the reservoir, often at high pressure, to increase the pressure within the reservoir and force more oil to flow out of the well.

In addition to these main applications, injection quills can also be used for other purposes in the oil and gas industry. For example, they can be used to inject cleaning fluids into pipelines to remove dirt, debris, and other contaminants. They can also be used to inject gases such as nitrogen or hydrogen into pipelines to create a protective atmosphere or to flush out the pipeline.

Overall, injection quills are an important tool in the oil and gas industry, providing a safe and efficient way to inject fluids into pipelines. They are used for a variety of purposes, including corrosion control, scale inhibition, and enhanced oil recovery, and are an essential part of maintaining the integrity and efficiency of pipelines.

Retractable injection quills: types and materials

Retractable injection quills from Crystal Industrial Syndicate are devices that are used to inject liquids or gases into a pressurized system, such as a piping system in a chemical plant. They typically consist of a needle or nozzle that can be inserted into the system through a small opening, and a mechanism for retracting the needle or nozzle when it is not in use. The main advantage of retractable injection quills is that they allow the user to inject fluids into the system without having to disconnect or open the system, which can reduce the risk of spills or leaks and make the injection process more efficient.

With retractable injection quills, the quill can be pulled out and put back in without having to depressurize the whole process. This is a very useful feature for people who work with chemicals like sodium hypochlorite, ammonia, and polymer that tend to clog.

Crystal Industrial Syndicate manufactures world-class retractable injection quills. Our retractable injection quills come in 4 main varieties.

STANDARD SERVICE RETRACTABLE
They can be used in a wide variety of chemical treatment applications because they can be made in different sizes and out of different materials.

HEAVY SERVICE RETRACTABLE
For purposes with longer insertion lengths, greater pressures, turbulent flows, and other harsh conditions.

HIGH CORROSION RESISTANT
More options for materials that can stand up to high chloride and other aggressive chemicals in process flows.

FLANGED RETRACTABLE
A durable design that uses a 250 psi dual-bolt restraint and a guide pipe assembly that helps support the restraint.

With retractable injectors, the injection quill can be put in or taken out while the system is still under pressure. It c Can be used when there is no way to turn off the pressure in the line. The employment of this removable injection quill enhances injection and diffusion and makes it possible to inject corrosive chemicals into a pipeline without hurting the pipe or threaded port at the injection point. When injected into the pipe’s centre stream, the chemicals are spread out more evenly because the pipe’s speed is higher and more turbulent.

In the past, this variety of retractable injector was called a “corporation stop injector.” However, high-quality ball valves have many benefits over the older model that utilizes a corporation stop for the valve that turns the flow off. The ball valve nipple will have a smaller space between the quill and the valve. This will make it less likely for the pipe to rattle when there is turbulence in the flow.

Available in 34″, 1″, 1-1/2″, and 2″ sizes, as well as custom sizes that are larger.

Construction materials for retractable injection quills
Retractable injection quills can be made from a variety of materials, depending on the specific application and the properties of the fluid being injected. Some common materials for injection quills include stainless steel, aluminum, brass, and plastic. The choice of material may be based on factors such as the temperature and pressure of the system, the chemical compatibility of the material with the injected fluid, and the mechanical strength and durability of the quill. In some cases, injection quills may be coated or lined with materials that provide additional chemical resistance or improve the sealing properties of the device.
