Natural gas is lighter than air and will not pool as a liquid or vapor. Technologies are needed to separate gas from liquids, to remove particles from gas, and to remove droplets from gas. LANL Standard Drawings and Details either (1) depict required format/content or (2) are templates that are completed by a Design Agency (LANL or external AE) for a design drawing package, in a manner similar to specifications. • Advantages of Gas turbine power plants. As a liquid, natural gas occupies only 1/600 of the volume of natural gas (at atmospheric pressure) in gaseous form, making LNG more economical and practical to store. Hydrates typically form in process where light hydrocarbons, water vapor and low temperatures or high pressures are present.
