Optimization Of Nature Gas Pipe Network Pressure Energy In Power Generation And Ice Making System

With the tensions in the world’s energy and the gradual awareness of the ecologicalenvironment, it promotes the booming of natural gas industry.Our country also takes active part in the natural gas industry, and in particular the mostimportant of which is the natural gas pipeline construction. Pipeline Transportation is themain natural gas modes of transport; the national has been constructed natural gas pipelinemileage up to60million meters. Natural Gas Pipelines, there is a huge amount of pressure,but the domestic pressure regulating stations and is not to be recycled. Through theappropriate processes and equipment, you can use this energy is converted to a cold andmechanical energy to be usedThis paper provides a first in China natural gas pressure to power generation-ice-systemof the model project for research background of the project, the process and key equipment toexplore the project stand-alone debug and process the regulation and in the analysis of theissues, and mainly the turbo expander speed too high to the lube oil system oil temperature istoo high, the oil system Chain control result of higher unit operating flexibility is not enough,the pump power consumption is large and the compressor load the current instability, and forsystem optimization.In response to the above question, the paper to screw expanders and star spin fluid motorperformance will be selected on the basis that the use of a replacement device star spin fluidmotor, the process of the fire with efficiency of42.6%with a capacity of120kW. Althoughimprovements in program fire with efficiency and power output dropped, but the powerequipment speed to drop the overall running costs and difficulty has been significantlyreduced. On the basis of this, the original process adjustment is a star spin fluid motor directdrive two compressors to achieve double-shaft, excess energy to be driven generators for siteuse. Investment of the optimization project is$4,800,000, and the investment recovery periodis7.42years. Finally, the paper does technical and economic analysis and operating flexibleanalysis and justifies the rationale and benefits of the optimization program.
