液化天然气（LNG）及天然气（NG）物性计算是LNG接收站生产、运行的基础。虽然国外已有很多商业软件可以计算其物性，但大多价格昂贵且应用复杂。因此，以BWRS方程为理论基础，在Forcecontrol V7．0平台上设计出一款应用简单，且能够满足LNG接收站需求的物性计算软件。通过将大连L N G接收站实际运行数据及A spen Plus计算数据与此软件计算数据进行对比，得到一些典型物性的相对误差；同时，通过实例计算以验证其可靠性。结果表明，该软件能较为准确地计算LNG及NG物性，并且能很好地满足LNG接收站物性计算的需求。

The production and operation of LNG terminal are based on liquefied natural gas (LNG) and natural gas (NG) properties calculation .Although there are many foreign commer-cial softwares which can calculate the properties , most of them are expensive and complex . Therefore ,BWRS equation as the theoretical basis ,the properties calculation software is de-signed based on the Forcecontrol V7 .0 software platform which is simple and can meet the needs of LNG Terminal .By comparing the data of the actual operation in Dalian LNG Terminal ,calcu-lated data by Aspen Plus and by this software ,relative errors about some typical properties have been received .Meanwhile ,the reliability of the calculation has been verified with some exam-ples .Results show that the software can provide fairly accurate calculation results of LNG and NG properties and can well meet the properties calculation needs of LNG Terminal .
