Engineering Services
From feasibility and selection to commissioning, operations and the retrofit a decade later.
Equipment is the start of the relationship
Technical Consulting & Selection
Starting from your gas demand curve, purity requirements, site conditions and capex ceiling, we compare processes, size the equipment and deliver feasibility plus payback analysis.
Process & Engineering Design
PFD, P&ID, equipment layout, piping stress and control philosophy, coordinated with design institutes through construction drawings and safety review.
Installation, Commissioning & Start-up
Resident project managers plus process and I&C engineers handle erection, piping, solo runs, integrated testing and handover to on-spec product.
O&M and Remote Monitoring
Live data feeds into our monitoring platform for energy analysis, fault alerts and annual maintenance planning, with optional fully outsourced O&M.
Retrofit & Energy Upgrade
Capacity expansion, purity upgrade, energy diagnosis and control-system renewal for aging ASU and PSA plants, typically paid back in 12 – 18 months.
Spares Supply & Operator Training
Customer-specific spare lists and safety stock, plus operator, maintenance and emergency-drill training with standardized work procedures.
