ExcelTest-ALT Alloy Electro-Chemical Anti-Scale & Anti-Wax Device for Oil Pipe Network & Downhole Pipe

Product Description:
The ExcelTest-ALT Alloy Electro-Chemical Anti-Scale & Anti-Wax Device is a patented non-chemical wax inhibitor tool (WIT) designed for the oil and gas industry. It effectively inhibits the formation and growth of carbonate nucleus, preventing the accumulation of waxes and asphaltenes in oil wells and oil pipes. The special alloy of copper, zinc, and nickel creates galvanic cells that increase the solubility of calcium carbonate and modify solvent & solute activity, inhibiting the formation of wax scale and algae corrosion.

The device's electrochemical working principle treats the water inside the circulation water pipe, preventing scale formation in the pipeline and containers, and ablates gradually the original old scale. It also softens and ablates long-existing wax, scale, and rust, preventing and slowing pipeline corrosion. The ALT device is environmentally friendly, easy to install, and maintenance-free, making it extremely suitable for pipelines at high or low positions, in wide fields, and other places difficult for people to operate.

Using the ExcelTest-ALT Alloy Electro-Chemical Anti-Scale & Anti-Wax Device can significantly reduce the deposition of solids in pipes, improve the utilization rate of pipelines and equipment, and prolong their service life. It also reduces the frequency of pipe cleaning & equipments maintenance, shortens the maintenance time, and saves maintenance costs.

Oil scale of oil field
Paraffin accumulation is the most common cause of oil well shut-down and maintenance. The paraffin wax is molecular chain length to C20 to C50 nonpolar hydrocarbon saturation, as a separate, semi-solid liquid separated from the oil, becoming much less liquidated. So it has tendency to form crystal in crude oil and depositing.
During oil extraction，the pressure and temperature decrease to certain levels when crude oil from field to the reservoir wellhead via bottom hole. The wax and asphaltene will isolate from crude oil, and form crystalline particles, accumulating and then deposite on the pipe wall. The accumulation of waxes and asphaltenes in oil wells and oil pipes is an industrial paint-point:
1. Cut down oil production, increase cleaning frequency and prolong the maintenance time;
2. Increases tubing loss, increases load the ground driving system, the pump efficiency is reduced, and the pump is easy to burn;
3. Increase the oil flow resistance; decrease the efficiency of pumping and the life of the equipment.

Working principle of ALT Inhibitor
anti-scaling and anti-wax devices

ALT anti-scaling device uses a special alloy of copper, zinc and nickel, totally more than 10 different types of metals. This special alloy will form a large number of galvanic cells upon contact with the fluid. Under this “electrolysis” process due to these tiny primary batteries (Micro-cells), the solubility of calcium carbonate will be increased and at the same time inhibited the formation and growth of carbonated nucleus. The micro-cell adsorption makes carbonate crystallization distorted, therefore, inhibit the forming of calcite (stable calcium carbonate crystal structure, dense, strong) of such crystals. The carbonate precipitation, in the fluid through the device, is generally converting crystal structure into a non-scaling crystal structure, which is not easy to bond metastable crystals (amorphous calcium carbonate) form. This non-scaling crystal structure is easy to flow, which caused anti-scaling effect.
The multi-metal alloy working as special catalyst that modify solvent & solute activity, so that the physical and chemical conditions will changed the Chemical-bond between molecules and ions of various substances in the fluid. These effectively inhibit the formation of wax scale and algae corrosion. The crystallized scale has been deposited to the wall will gradually ablation off or removed.
Fluid flow through the ALT anti (removal) scale device will collide and caused friction and brushing effect with the multi-metal alloy wall. In this turbulent state，the solid-phase particles in the fluid will keep it non-scaling structure and suspends in a dispersed state, for a certain period of time and a certain distance. This contributes

Anti-wax working principle
When crude oil enters the LT3F-J combined downhole device under the influence of ground pressure or pump pressure, the crude oil comes into contact with the hole of special alloy disc and forms a large number of fine columnar jets through the alloy disc holes, resulting in a flow impact to increase the liquidity. The disc surfaces release original battery electrons which act on water molecules in crude oil to avoid water scale, an important cause of the oil scaling. Meanwhile the metal ions of the alloy go into the crude oil with a catalytic role in effectively changing some of the physical properties of crude oil to prevent wax from being released from crude oil to form a solid deposition, thereby the mobility of crude oil is improved.
Waxes in the crude oil treated by the LT3F-J unit and other waxy materials that tend to clump and clog the tubing are in suspension. Under the Catalytic action of the alloy catalyst, hydrocarbon molecules, long-chain fracture, the crude oil becomes more smooth. For high waxy and low severity crude oils, this treatment can increase the crude oil APIs by 2-3 percentage points.

Features and Advantages of Inhibitor

Hindering the adsorption and bonding between solid ions to prevent water & wax scaling, fouling and corrosion of the pipe and circulation system, the Anti-scaling devices can greatly reduce the deposition of solids in the pipes.
No magnetic, no electricity, without adding any chemicals & environmentally friendly products.
Easy installation and maintenance free; Extremely suitable for pipeline at high or low position, in wide field and other places difficult for people to operate.
Softening & ablating long exists wax, scale and rust, to prevent and slow pipeline corrosion.
Inhibit algae growth.
Improve the utilization rate of pipeline as well as equipment; Prolong the service life.
Reduce the frequency of heat exchange maintenance, shorten the maintenance time, save maintenance costs.

ALT anti-scaling device’s is using electrochemical working principles, which effectively treat the water inside the circulation water pipe. While keeping the original operation mode of the water system, the water treated by the ALT anti-scaling device can prevent scale forming in the pipeline and containers, & also ablate gradually the original old scale. This action will restrain the corrosion of the pipeline and the equipment and deoxygenate algae. ALT device can ensure effective function without maintenance more than five years. This is great advantage compare with other chemical and physical anti-scaling technology.
