Heavy Hydrocarbon Removal Once the feed gas passes through the first pass of the refrigerant exchanger, it is withdrawn at a "midpoint" temperature. The two-phase stream is then sent to the Heavies Separator, 23-V-0104 where the vapor phase is directed back to the refrigerant exchanger for liquefaction. The small amount of condensed heavy hydrocarbon liquid from the bottom of the Heavies Separator is sent to the Heavies Reheat Exchangers, 23-E 0105 and 23-E-OI06. The vaporized hydrocarbons are mixed with the boil-off gas, used for regeneration gas, and subsequently consumed as fuel. Some small amount is left as liquid and is sent to the slop drum for disposal. 重烃去除 一旦原料气首次流经制冷交换器时，原料气将以“中点”温度被撤出。双相气流被送至重烃分离器Heavies Separator23-V-0104，经过分离，蒸发气相被直接返送回制冷交换器进行液化。来自重烃分离器底部小量的冷凝重烃液体被送至重烃再加热交换器Heavies Reheat Exchanger 23-E-0105和23-E-0106。蒸发后的烃混合着蒸发气用于再生气，之后可以当做燃料使用。某些少量以晶体的形式离开被送至污水油罐处理。 |
