Engineering Tools & Calculators
Interactive gas analyzer selection workflows, embedded analyzer calculators, and standalone engineering utilities for faster front-end specification work.
Featured Tools
Start with guided selection, then open engineering checks.
Use the selector for analyzer fit, or open the engineering calculator library for standalone fired-heater, steam, pressure-drop, and heat-transfer utilities.
Gas Analyzer Selector Wizard
Answer guided questions, select the target gas and process context, then review analyzer recommendations by application fit.
Engineering Calculators Library
Open standalone calculators for steam properties, API 530 tube wall checks, fired-heater balance, pressure drop, heat transfer, and utility estimates.
Tools by Gas Workflow
Open the right selector, calculator, or comparison path by gas family.
These cards route to live branded tools. Rich analyzer pages handle syngas, methane, biogas and gas purity calculators; ammonia, H2S and chlorine start inside the gas selector wizard.
Ammonia
SCR/SNCR slip, CEMS context, cold-storage safety, and process NH3 selection.
NH3 Analyzer Selector
Start the wizard with ammonia preselected, then choose the application and process conditions.
NH3 Application Prompts
Use the wizard prompts to separate SCR slip, stack emissions, process monitoring, and safety duty.
NH3 Shortlist Wizard
Build a guided shortlist before discussing TDLAS, UV-DOAS, NDIR, or electrochemical tradeoffs.
Hydrogen Sulfide
Sour gas, biogas, refinery, and safety applications with ppb-to-percent selection needs.
H2S Analyzer Selector
Open the selector with H2S selected for application and sample-path recommendations.
H2S Application Prompts
Capture the application context needed before installed-cost or maintenance discussion.
H2S Shortlist Wizard
Start from process duty before comparing UVF, electrochemical, and other H2S paths.
Methane Analysis
Process and emissions CH4 analysis; flammable-atmosphere safety detection lives under Combustible Gas Detectors.
Methane Analyzer Selector
Use the methane page selector for process and emissions CH4 analyzer fit.
Methane TCO Calculator
Compare ownership assumptions for methane analyzer technology decisions.
TDLAS vs NDIR vs FID
Review the static technology comparison table on the methane analyzer page.
Chlorine
Gas-phase chlorine and aqueous residual chlorine selection paths stay separated by application context.
Chlorine Analyzer Selector
Open the selector with chlorine preselected before choosing gas-phase or water-treatment duty.
Unit & Application Prep
Start the pathway for ppm, mg/m3, process gas, or residual-chlorine discussion.
Gas vs Aqueous Path
Use application prompts to separate UV-DOAS gas-phase chlorine from water-treatment analyzers.
Biogas & Landfill
Analyzer selection, composition reference, and ownership modeling for CH4/CO2/H2S streams.
Biogas Analyzer Selector
Choose monitoring objectives for digester, upgrading, landfill, or engine-protection duty.
Biogas TCO Calculator
Model ownership assumptions for biogas and landfill gas monitoring programs.
Gas Composition Chart
Review typical biogas and landfill gas composition ranges before analyzer selection.
Gas Purity
Gas separation, specialty-gas QA, process purity, and technology economics.
Purity Analyzer Selector
Select the gas and purity workflow before comparing analyzer technologies.
Purity TCO Calculator
Estimate ownership impact across TDLAS, TCD, and EC purity analyzer paths.
Spec Comparison
Review ZS-series analyzer specifications for gas purity applications.
Syngas
Gasification composition, analyzer selection, and cost comparison for CO/H2/CO2 process streams.
Syngas Analyzer Selection
Open the syngas calculator suite and start with analyzer selection logic.
Composition Calculator
Use the syngas suite for composition ratios and process stream assumptions.
Syngas TCO Comparison
Open the same branded suite for total-cost comparison across analyzer choices.
Engineering Calculators
Standalone design utilities for fired-heater and process engineering checks.
Each calculator opens in a separate tab as a self-contained utility, so the library stays fast to browse while preserving quick access from the tools hub.
