Gas composition. Methanol and/or glycol shall not be deliberately added to the natural gas. Cylinder should be designed to tolerate being filled with natural gas meeting either of the following three conditions:
(a) SAE J1616
(b) Dry gas Water vapour would normally be limited to less than 32 mg/m3. a pressure dewpoint of -9 °C at 20 MPa. There would be no constituent limits for dry gas, except for: Hydrogen sulfide and other soluble sulfides: 23 mg/m3 Oxygen: 1 per cent by volume Hydrogen shall be limited to 2 per cent by volume when cylinders are manufactured from a steel with an ultimate tensile strength exceeding 950 MPa;
(c) Wet gas Gas that contains a water content higher than b) normally meets the following constituent limits; Hydrogen sulfide and other soluble sulfides: 23 mg/m3 Oxygen: 1 per cent by volume Carbon dioxide: 4 per cent by volume Hydrogen: 0.1 per cent by volume Under wet gas conditions, a minimum of 1 mg of compressor oil per kg of gas is necessary to protect metallic cylinders and liners.

Gas composition. The composition and Gross Heating Value shall be determined by composite sampling and analysis every thirty (30) days, or sooner at Gatherer’s sole election, by Gatherer at the Receipt Points. Such sampling and analysis shall conclusively establish the composition and Gross Heating Value of Shippers’ Gas until such sampling and analysis is conducted again. Gas delivered at the Receipt Points, downstream of any dehydration equipment, having a water content of [***] pounds per Mcf, or less, shall be considered dry, otherwise the Gas shall be considered fully saturated.
Gas composition. The composition and Gross Heating Value shall be determined by:
