The Guide focuses on systems and arrangements provided for the safe delivery of natural gas by means of regasification systems. simple flow sheet • Refrigerated Gas Plant o Build a more complex flow sheet, Heat Exchangers and Logical unit operations (Balance, Adjust). 5 × 10 3 kg mol/h, and the composition is 83, 12, 4, and 1 mol percent methane, ethane, propane, and n -butane, respectively. creating a natural gas industry boom. The Lean amine and Rich amine flow through the heat exchanger, heating the Rich amine. Together they transport and control the flow of the natural gas or oil from its origin point at the wellsite to a main storage facility, a processing plant, or a shipping point.
