CO2 Conversion Guide

Converting liquid CO2 into cubic feet or other units of measurement accurately is crucial for operational efficiency and safety. This guide provides a clear breakdown of how to calculate these conversions and essential safety standards for handling CO2.

Volume Calculations

Knowing the specific conversion rates is essential when converting liquid CO2 to its gaseous form. This knowledge helps calculate how much gas can be derived from a given amount of liquid CO2, whether for industrial or commercial purposes. For instance, 1 gallon of liquid CO2 equals 74.04 standard cubic feet (SCF) of CO2 gas. 

CO2 Conversion Data

Below is a quick reference table to help convert liquid CO2 to various units of measurement.

Legend
  • scf (standard cubic foot) gas measured at 1 atmosphere and 70°F.
  • Nm3 (normal cubic meter) gas measured at 1 atmosphere and 0°C.
  • Liquid measured at 1 atmosphere and boiling temperature.

Safety Standards and Usage

Following industry safety guidelines is crucial to protecting personnel and equipment when handling carbon dioxide, especially in its liquid or gaseous form. CO2 is 1.5 times heavier than air, so it can accumulate in low or confined spaces and pose suffocation risks. Always adhere to Occupational Safety and Health Administration (OSHA) standards, which outline protocols for safe storage, handling and monitoring.

Key safety reminders include:

  • Use proper ventilation and monitoring equipment.
  • Liquid CO2 and dry ice (solid CO2) are extremely cold and can cause frostbite or burns upon contact. Wear appropriate personal protective equipment (PPE) when handling.
  • Ensure CO2 containers and systems are regularly inspected to prevent leaks or overpressurization.
  • Always read and understand the Safety Data Sheet (SDS) before using CO2. This document outlines potential hazards and safe handling procedures.
  • If you have any questions or concerns regarding CO2 safety, contact a Meritus Gas Partner representative for expert advice.
