Chemical Reactor Conversion Calculator

Calculate the required volume of a continuous stirred-tank reactor (CSTR) to achieve a target conversion for first- or second-order reactions. Essential for chemical process design and scale-up.

Initial Reactant Concentration (mol/L)

Reaction Rate Constant (L/mol·s)

Volumetric Flow Rate (L/min)

Desired Conversion (%)

Reaction Order

Gas Absorption Column Design Calculator

Design a packed gas absorption column by calculating the number of overall gas-phase transfer units (NOG) and total column height needed to achieve a target gas-phase separation. Used in scrubber design for air pollution control and chemical processing.

Inlet Gas Concentration (Y₁) (mole fraction)

Outlet Gas Concentration (Y₂) (mole fraction)

Henry's Law Constant (atm·L/mol)

Liquid to Gas Ratio (L/G)

Height of Transfer Unit (HOG) (ft)
