APSL Systems

What APSL Systems does

APSL Systems Limited is a privately-held UK engineering firm, headquartered in Rugby, Warwickshire, that designs and supplies process separation equipment for the global oil and gas industry. Founded in 2012, the company specializes in produced water treatment and seawater treatment equipment for both onshore and offshore applications, serving oil and gas exploration and production operators as well as refining and petrochemical facilities. Its portfolio spans primary, secondary and tertiary treatment stages and includes plate separators, deoiling and desanding hydrocyclones (marketed under the proprietary Twin-Spin brand), induced gas flotation units, deep bed nutshell filters, cartridge and bag filters, multi-media fine filters, vacuum and gas-strip deaerators, and ancillary solids handling equipment such as slurry-jets and sand cleaning systems.

The underlying technology is grounded in mechanical process engineering rather than software or AI: hydrocyclones use semi-axial inlets and compact liner geometries to generate higher g-forces for finer oil droplet and solids removal, while filter designs emphasize high-efficiency automatic backwashing suited to offshore conditions. APSL operates a direct enterprise sales model, supplemented by a global network of agents, and delivers customized equipment packages worldwide — with disclosed project wins spanning West Africa, Central Africa, the Norwegian Continental Shelf, the Gulf of Mexico and South America. The company has been ISO 9001:2015 certified since September 2018, which functions as a baseline qualification for bidding on major operator procurement frameworks.

APSL generates revenue primarily through one-time supply of capital equipment and integrated process packages, with an aftermarket layer providing retrofits, upgrades, spare parts and engineering support regardless of original equipment manufacturer. Pricing is quote-based with no publicly disclosed price points, and contracts typically span multi-year project execution cycles. The customer base is concentrated in oil and gas enterprise operators, with repeated business from West African FPSO and platform operators representing a significant share of disclosed wins.

Brands

• Twin-Spin: Twin-Spin is APSL's proprietary technology brand featuring high-performance hydrocyclone designs with unique features for improved reliability, longevity, and separation efficiency.

Products and services

• Twin-Spin Deoiling Hydrocyclones High-performance liquid-liquid hydrocyclones for produced water deoiling featuring semi-axial inlets that reduce turbulence and oil droplet shear, smaller internal diameters generating higher g-forces for removing smaller oil droplets, increased capacity at very low pressure loss per unit, and smaller liner OD enabling compact vessel configurations. Sold to oil and gas operators for offshore and onshore produced water clean-up.
• Twin-Spin Desanding Hydrocyclones Solid-liquid desanding hydrocyclones for sand and solids removal from multi-phase, gas, and produced water streams, including wellhead multiphase separation and high-pressure pre/post-choke proppant removal. Available in sizes from 12mm to 100mm with erosion-resistant ceramic materials, no moving parts, broad particle removal range from 5 microns to mm, and compact footprint.
• Deep Bed Nutshell Filters Next-generation automated, self-cleaning granular media filter using walnut shell media that outperforms other granular media filters by fluidising and fully suspending media and contaminants for regeneration, and by delivering consistent polishing performance in produced water polishing applications.
• Mechanical and Hydraulic Induced Gas Flotation Units High-performance vertical single-cell and horizontal multi-cell hydraulic and mechanically induced gas flotation machines for removing hydrocarbons and solids from produced water in offshore and onshore oil and gas facilities.
• Compact Flotation Units Compact flotation units for separating oil and solids from produced water, designed for superior separation performance in a compact footprint suited to space-constrained offshore platform installations.
