Liquid Nitrogen Applications for Upstream and Midstream Operations

Kathairos eliminates methane emissions from pneumatic process controls and pumps across midstream facilities by replacing supply gas from pneumatics with inert, high-pressure nitrogen supplied from our cryogenic liquid nitrogen tanks. Our system integrates seamlessly with existing equipment—requiring no production interruptions—while delivering stable, reliable pressure for consistent control performance. Designed for remote and extreme environments (-50°F to 110°F), Kathairos’ autonomous, low-maintenance solution enabling zero methane venting and full regulatory compliance without modifying existing equipment or interrupting production.

Instrument air failures at midstream facilities can quickly compromise pneumatic controls, disrupt operations, and lead to costly downtime, particularly during extreme weather events. Kathairos’ liquid nitrogen system provides a dependable, autonomous backup supply of compressed nitrogen gas to maintain critical valve actuation and control system performance when instrument air systems fail. With immediate availability, no moving parts, and zero methane venting, Kathairos ensures uninterrupted valve actuation and site revenue across midstream assets in temperatures ranging from -50°F to 110°F.

Midstream compressor stations rely on properly sized start air receivers to deliver the surge required for engine starts. Kathairos’ liquid nitrogen system keeps those receivers charged with bone-dry gas and provides a standby start source when instrument air is unavailable due to compressor or dryer issues, power loss, or winter freeze-up. This improves operational resilience and reduces methane venting during start events where gas-start is used.

Kathairos’ liquid nitrogen tank solution is an ideal fit for midstream operators performing minor facility equipment purging because it provides an on-demand source of clean, dry, inert nitrogen without relying on an outside power supply. Our self-contained system can safely displace oxygen and residual hydrocarbons to reduce explosion risk and keep maintenance windows tight. With reliable performance in extreme temperatures and minimal maintenance requirements, Kathairos enables safer, more efficient purging operations across remote and operationally demanding midstream facilities.

Kathairos’ liquid nitrogen solution enhances stock tank inert gas blanketing across midstream terminals, storage facilities, and stabilization sites by delivering a consistent nitrogen supply to tank vapor spaces, maintaining positive pressure and preventing oxygen ingress. Our stand-alone solution integrates seamlessly, requiring no external power or complex infrastructure. By maintaining stable positive pressure within atmospheric storage tanks, Kathairos helps midstream operators improve safety, reduce VOC emissions, support regulatory compliance, protect critical storage assets, and keeping midstream terminals running without added complexity or maintenance burden.

Kathairos increases site reliability by delivering dry, inert nitrogen that maintains consistent pneumatic pressure and prevents control failures before they occur. Our liquid nitrogen solution provides ultra-reliable pneumatic pressure with no moving parts and no outside power requirements, ensuring continuous operation even in the harshest environments. Engineered to perform in extreme temperatures from -50°F to 110°F, Kathairos keeps critical controls running consistently, reducing downtime and safeguarding operational performance in any weather.

With over 850,000 tCO2e eliminated in 4 years, Kathairos helps operators significantly decrease quickly and at scale facility emissions by eliminating methane venting from pneumatic devices across upstream and midstream operations faster than any other solution. By replacing methane operated pneumatics with inert nitrogen supplied from our standalone liquid nitrogen system, operators can achieve immediate and measurable emissions reductions without modifying existing equipment or disrupting production. Designed for remote, off-grid sites and extreme operating conditions, Kathairos provides a reliable, zero-emissions alternative that supports regulatory compliance, Scope 1 emissions reporting, and long-term emissions targets — deployable at any scale, across any site, without interrupting operations.

Kathairos provides empirical venting performance monitoring and reporting that gives operators clear, defensible insight into their operational venting performance. Our systems quantify nitrogen usage and corresponding methane displacement at the site level, enabling producers to see exactly how much methane is being eliminated at each site. This data-driven approach supports transparent reporting to regulatory bodies and voluntary frameworks such as OGMP 2.0, while strengthening ESG disclosures and audit readiness. With accurate, site-level performance data, Kathairos empowers operators to validate emissions reductions, demonstrate progress toward targets, and build audit-ready credibility with regulators, investors, and emissions verification bodies.

Kathairos enables operators to generate high-quality emissions reduction offsets by delivering methane reductions that go beyond regulatory requirements. For every tonne of CO2e avoided through the replacement of methane-driven pneumatics with nitrogen, eligible carbon credits can be created—transforming emissions reductions into tangible financial value. As both a field-level solutions provider and an experienced carbon accounting partner, Kathairos manages the technical quantification, documentation, and serialization process required to bring offsets to market. By overseeing the regulatory and verification complexities, we allow energy producers to focus on the operational and economic returns of their emissions reduction program — while we manage the pathway from methane elimination to marketable carbon credits.

Kathairos is built for rapid, enterprise-wide scalability—whether deploying at a few sites or across thousands—with delivery timelines in less than 8 weeks. Our easy-to-install systems allow operators to keep all existing infrastructure and pneumatic devices, eliminating the need for costly retrofits or operational disruption. With standardized tank sizes optimized for site operations and economics, Kathairos enables companies to implement a consistent, repeatable methane reduction strategy that scales seamlessly across their portfolio.

Kathairos delivers consistent performance and predictable costs across the full life of a site — from new commissioning to abandonment. No moving parts, no external power, and 30+ day refill cycles eliminate maintenance burden and service call overhead. Deployed on a monthly rental model, there's zero upfront capital, just a predictable OPEX line that right-sizes your site's production and economics as they evolve.

When total cost of ownership is calculated — factoring in any avoided methane fees, reduced downtime, and potential offset revenue — Kathairos delivers a net positive economic outcome. A solution that pays for itself and keeps performing, for the life of the site.
