Abstract

The invention provides an LNG light dydrocarbon separation coupled geotherm flash evaporation/Karina combined cycle power generation system. The system comprises an LNG light dydrocarbon separation system, a geotherm flash evaporation cycle system, a Karina cycle system and a natural gas direct expansion system. The LNG light dydrocarbon separation system is used for recycling C2+ light dydrocarbon resources. The geotherm flash evaporation cycle system, the Karina cycle system and the natural gas direct expansion system are used for LNG cold energy and medium-low-temperature geothermal energycoupling power generation. While the geotherm flash evaporation/Karina combined cycle power generation efficiency is improved, effective recycling of the C2+ light dydrocarbon resources and efficientcomplementary use of LNG cold energy and geothermal energy are achieved, and the system has the beneficial effects of being reasonable and compact in structure, safe and flexible in control, efficient, high in practicality and low in cost and saving energy.

Description

technical field [0001] The invention relates to an LNG cold energy and geothermal energy complementary utilization system, in particular to a LNG light hydrocarbon separation coupled geothermal flash / Karina combined cycle power generation system. Background technique [0002] LNG (liquefied natural gas, liquefied natural gas) needs to be gasified to normal temperature before being supplied to users. LNG will release about 830-860kWh / kg of cold energy during the gasification process. If this part of cold energy can be utilized, it will produce huge economic benefits. The rich C2+ light hydrocarbon components in LNG are very high-quality chemical raw materials, which can be used to produce many petrochemical products with high added value. Using LNG cold energy to separate its own light hydrocarbon components can realize efficient utilization of LNG, but the utilization rate of LNG cold energy is not high. [0003] The geothermal flash cycle has the advantages of low power g...
