DistPad vs Haverly's PetroCalc

Utility App for wireless control of atmospheric distillation analysers from ORBIS BV that are used in Petroleum & Petrochemical Laboratories. The app is capable of controlling the atmospheric distillation analysers of ORBIS BV, provides information about the analysers and reports the results of the analysers in a tabular and graphical manner. A set of standard methods allows to easily set up measurement programs that can be send to one of the connected analysers. A status screen provides information about the current status of each sample currently running on one of the analysers. Results can be viewed real time while the instrument is running or upon completion of the test. Results can be exported via ftp connection in xml format to a remote database (LIMS) Laboratory information management system. or printed on a Zebra thermal printer. The format of reporting to the printer or LIMS can be set easily on a formatting screen which can be set as a global default setting or for each standard method or program individually. The program parameters for each Sample (tasks) that are due to run ,currently running or being finished can be changed at all time. The parameters that can be changed are depending on the status of each task. Reference samples can be monitored using the reference screen showing consistency of each analyser. Frequency of verification and recalibration of the analysers can be set in the system settings screen along other parameters.

PETROCALC – THE TRUSTED PETROLEUM CALCULATOR IN YOUR POCKET PetroCalc is the all‑in‑one oil & gas calculator that engineers, technicians, and students rely on for fast, accurate viscosity calculations, crude‑oil blending, and every other petroleum‑property task. Whether you need an oil calculator for the field, a crude‑oil calculator for the lab, or a classroom reference, PetroCalc streamlines every petroleum calculation—from viscosity blending to heating‑value look‑ups—completely offline. KEY FEATURES • Unit Conversion – Instantly switch between energy units (MJ/m³, MBTU/bbl, BTU/gal, kCal), temperature (°F/°C), pressure (psi/bar), oil‑density & gravity (kg/m³, API °, specific gravity), kinematic ↔ dynamic viscosity (cSt ↔ cP) and operational scales (SUS, SFS, Redwood I, Engler °), plus calorific‑value conversions and more with our intuitive oil & gas calculator interface. • Distillation‑Curve Tools – Convert temperatures between TBP, ASTM D86, D1160, and D2887 scales and perform yield‑temperature interpolation for full distillation‑curve analysis. • Blending Tools – Execute precise crude‑oil blending and petroleum blending for RVP, Flash Point, Smoke Point, Pour / Cloud / Freeze Point, API Gravity, Aniline Point, Mercaptan Sulfur, Nitrogen, and custom fractions. • Fuel Property Indices – Compute Cetane Index (ASTM D4737 A/B, D976), Driveability Index, Refractive Index, and additional viscosity calculations. • Heating Values – Obtain Gross & Net HHV in MJ/m³, MBTU/bbl, BTU/gal, kCal/kg, and more. • Boiling‑Point Utilities – IBP/EBP plus five average‑boiling‑point methods (Volume, Weight, Molal, Cubic, Mean). • K‑Factor Calculations – UOP K, Watson K, VRC K, Whole‑Crude K at any temperature. • Viscosity Prediction – Single‑point, two‑point (Twu), and API 11A4.2 models with built‑in viscosity‑blending conversions. WHY PETROCALC? • Developed by Haverly Systems, a leader in petroleum‑process modeling. • Optimized for petroleum, chemical, and process engineers—and perfect for students in engineering courses who need a dependable petroleum calculator and oil calculator for coursework. • Works fully offline—no data connection required on‑site. • Simple, accurate, and fast: the only crude‑oil calculator and petroleum‑blending tool you’ll ever need.
