Equipment

Lifecycle & Quality Management (Procurement to Site)

This indicates full ownership of the technical procurement cycle and quality compliance for heavy rotating and static process equipment i.e.

Fans (Centrifugal & Axial),

Dampers,

Pneumatic Conveying Systems,

Air Dryers,

Compressors (Reciprocating, Screw & Centrifugal) Air Receiver Tanks

Valves.

Technical Specification Preparation: Defining exact operating parameters, material of construction (MOC), codes/standards (e.g., ASME, API, ISO), and performance guarantees.

Offer Vetting & Technical Comparative Statements (TCS): Evaluating technical bids from various vendors against the project design criteria to ensure apples-to-apples comparison and eliminate non-compliant options.

Drawing & QAP Approval: Reviewing general arrangement (GA) drawings, piping and instrumentation diagrams (P&IDs;), and Quality Assurance Plans (QAP) to ensure compliance with project standards before manufacturing begins.

Inspection Report Review & Physical Inspection: Conducting Factory Acceptance Tests (FAT) and physical inspections at vendor shops based on the approved Quality Control Plan (QCP).

Site Installation Supervision: Ensuring mechanical alignment, foundation checking, safety compliance, and proper erection during installation.

- Enthalpy & Combustion Engineering Calculations

This represents the core of process design for furnaces, boilers, or thermal processing plants:

Stoichiometric Process Calculations: Determining the theoretical and actual mass balance of air required for complete fuel combustion.

Gas Density Calculation: By using Molecular Weight of individual gases.

Enthalpy & Sizing: Calculating thermal loads, heat balances, energy additions/losses, and temperature gradients.

System Resistance & Combustion Air Requirement: Mapping out pressure drops across the combustion air path to properly size Force Draft (FD) or Induced Draft (ID) fans.

Flue Gas Generation & Fuel Inputs: Calculating the composition, mass, and volume of flue gas generated to size exhaust ducting, chimneys,



and pollution control equipment. 3.

Industrial

Refrigeration & Chillers

This shows expertise in deep-cooling and heavy HVAC infrastructure:

VAM (Vapor Absorption Machine) Chillers: High-level understanding of heat-driven cooling cycles (lithium bromide-water or ammonia-water systems) designed to utilize waste heat or low-pressure steam, optimizing a facility's thermal efficiency.

Refrigerant Compressor Chillers: Knowledge of electricity-driven mechanical vapor-compression cycles using reciprocating, screw, or centrifugal compressors to manage heavy chilled water networks.

- HVAC & Pressurized Ventilation System Design

This covers cleanroom or industrial building climate control and air management:

Pressurized Ventilation Design: Engineering positive/negative pressure systems to prevent contamination or hazardous gas buildup (crucial for control rooms and chemical labs).

Ducting Engineering: Performing external static pressure (ESP) calculations, developing Bill of Quantities (BOQ), building layout drawings, and fabricating detailed duct isometric/shop drawings. 5.

Compressed Air Distribution

Networks

This highlights utility engineering skills for plant air and instrument air infrastructure:

Pipeline & Loop Sizing: Calculating friction loss, air velocity, and pressure drops using fluid dynamics principles to optimize pipe diameters.

Pressure Regulating Valve (PRV) Sizing: Designing set pressure range in order to meet system criteria.

Air Receiver Tank Sizing: Calculating necessary storage volumes based on compressor capacities, modulation cycles, and peak plant demands to maintain network stability.

- Software & Analytical Tools

Custom Excel Formula Development: Building complex, automated engineering spreadsheets for iterative calculations (e.g., pipe friction factor via the Colebrook-White equation, psychrometric properties, or automated BOQ tallies).

AutoCAD Drafting: Developing precise engineering deliverables such as process flow diagrams (PFDs), P&IDs;, equipment layouts, and installation schematics, equipment development drawing (reverse engineering & retrofitting).
