ProSep

What ProSep does

ProSep is a Houston-headquartered, privately held provider of proprietary process separation and mixing technologies for the global oil and gas industry, operating from a portfolio of patented products across the upstream, midstream, LNG, and downstream value chain. The current entity was established in November 2013 when PWA Inc. acquired the assets of the original ProSep Inc. (founded 2005 in Houston by former Kvaerner Process principals). The product portfolio is anchored in two technology families: (1) high-efficiency injection mixers — AIM, MAX+, ECLIPSE, ProSalt, ProMix, ProScav, ProDry, and ProBlend — designed to deliver >90% mixing efficiency and 20-60% reductions in chemical and wash water consumption; and (2) produced water treatment systems — Osorb regenerable silica media, TORR, and CTour — engineered to remove dispersed, emulsified, and soluble hydrocarbons (including BTEX and PAHs) down to sub-10 ppm oil-in-water levels. AIM technology improvements were granted US Patent 11,673,104 B2 in 2024.

The business model is project-based capital equipment sales with custom quoting, supplemented by third-party ASME-certified fabrication services in Houston, technology licensing (Osorb media), and lifecycle engineering/commissioning services. Pricing is not publicly disclosed; individual contracts have ranged from roughly $350K (single ProSalt unit) to $25M (Shell Canada Carmon Creek). Distribution combines direct enterprise field sales out of Houston with regional offices in Aberdeen (Europe), Abu Dhabi (Middle East), Al Khobar (MENA), and Kuala Lumpur (Asia Pacific), plus channel representation via Petrotec in Qatar and local fabrication partners in Saudi Arabia. Notable enterprise customers include Saudi Aramco, Shell Canada, Equinor, Aker BP, SAPETRO, and a Middle East NOC, alongside new entry into the US downstream refinery segment in 2024. The company has also extended into carbon capture (CLIMIT-funded Minox Compact CO2 project, 2023) and is pursuing IOT-enabled offerings, signaling an effort to broaden beyond its traditional mixing/water-treatment core.

Core offering

ProSep designs, manufactures, and sells proprietary process separation and high-efficiency mixing technologies for the oil and gas industry. Its portfolio includes patented injection mixers (AIM, MAX+, ECLIPSE, ProSalt, ProMix, ProScav, ProDry, ProBlend), produced water treatment systems (TORR, Osorb Media, CTour Process), gas processing solutions (CO2 Membranes), and full-lifecycle engineering and fabrication services for upstream, midstream, LNG, and downstream operators worldwide.

Product overview

ProSep is an integrated process separation solutions provider offering a portfolio of proprietary technologies for the oil, gas, and water treatment industries. The product portfolio consists of three main categories: (1) Mixing Technologies including AIM, MAX+, ECLIPSE, ProSalt, ProMix, ProScav, ProDry, and ProBlend for chemical injection, water mixing, and gas processing applications; (2) Produced Water Technologies including TORR, Osorb Media Systems, and CTour Process for treating produced water, process water, and quench water streams to remove hydrocarbons and contaminants; and (3) Gas Processing solutions including CO2 membranes and ProDry for dehydration and sweetening. The company also offers Energy Services encompassing design, engineering, and consultancy. These technologies enable operators to reduce chemical and water consumption, meet environmental regulations, and optimize separation performance across upstream, midstream, and downstream operations.
