摘要
为了提高煤矿区低浓度煤层气的利用率,扩大低浓度煤层气的利用途径,针对开发的低浓度煤层气提质制压缩天然气技术,以年产2 000万Nm^3压缩天然气项目为例,进行了设备选型,计算了公用工程消耗、项目投资,分析了项目的经济性及成本。结果表明,项目用电1 562.56万kWh,用水2.672万t,用气96万Nm^3,用地18 000 m^2。项目总投资7 846万元,建设投资6 990万元,其中工程费用5 621万元,其他费用2 225万元。压缩天然气销售价格为2.6元/Nm^3时,项目的财务内部收益率为31.87%(税后),投资回收期为4.44 a(含1.5 a建设期),单位产品成本为1.3元/Nm^3。
In order to increase the utilization rate and extend the utilization routes of low concentrated coal-bed methane,the equipments selection,utility consumption and project investment as well as economy and cost were calculated on the basis of as-developed low concentrated coal bed methane（ CBM） upgrade to compressed natural gas（ CNG） technology,with an annual output of 20 million standard cubic meters natural gas project as example.The results shows that the electricity consumption is 15.625 6 million kWh; the water consumption is 26.72 thousand tons; the gas consumption is 0.96 million Nm^3; the floor area is 18 thousand m^2.The total investment of this project is ￥ 78.46 million; while the construction investment is ￥ 69.9 million. The construction cost is ￥ 56. 21 million and the other costs are ￥ 22. 25 million.Accordingly,when the selling price of CNG is ￥ 2.6 per Nm^3,financial internal rate of return of the project is 31.87%（ after tax）;while the investment recovery period is 4.44 years（ including 1.5 years construction period）.And the unit product cost is ￥ 1.3 per Nm^3.
