No part of this Report may be reproduced without the written consent of GPA Midstream Association ii IMPACT STATEMENT Standard for Liquid Petroleum Gas Specifications and Test Methods GPA 2140 Purpose This standard encompasses
9、the specification that generally defines physical properties and characteristics for liquid petroleum gases (LP-Gas) for use in private, commercial, or industrial applications. The current revision adds the referenced testing method for sulfur ASTM D-5623 and vapor pressure ASTM D-2598. It adds a fo
10、otnote related to the vapor pressure reference method to be used in case of dispute. It also removes ASTM testing method year references and makes various editorial and spelling additions and corrections. Impact It is not expected that the changes to this Standard will have any new or further impact
11、. The user of this Standard should perform their own economic evaluation to include the use of handheld portable electronic devices as applicable. iii FOREWORD These specifications generally define physical properties and characteristics of liquefied petroleum gases (LP-Gas) which make them suitable
12、 for private, commercial, or industrial applications. These specifications do not purport to specifically define all possible requirements to meet all possible applications. Therefore the user is cautioned to exercise judgment in formulating final specifications for specific applications. The GPA Mi
13、dstream Association, its management, and supporting companies claim no specific knowledge of how manufacturers and users will produce, handle, store, transfer or consume the products defined herein and therefore, are not responsible for any claims, causes of action, liabilities, losses or expenses r
14、esulting from injury or death of persons and/or damage to property arising directly or indirectly from the use of LP-Gas or these specifications relating to LP-Gas. LP-gases are composed of hydrocarbon compounds, predominately propane and butane, produced during the processing of natural gas and als
15、o in the conventional processing of crude oil. The composition of LP-gases may vary depending on the source and the ratios of propane and butane content. They exist as gases at atmospheric pressure and ambient temperatures, but are readily liquefied under moderate pressures for transportation and ut
16、ilization. There are many uses for LP-gases, the major ones being as (1) petrochemical, synthetic rubber, and motor gasoline feedstocks, and as (2) commercial, domestic and industrial fuel. The following may be accepted as a general guide for the common uses for the four fuel types covered by these
17、specifications: Commercial Propane is the preferred fuel type for domestic, commercial and industrial fuels. It is also a suitable fuel for low severity internal combustion engines. Commercial Butane is used principally as feedstock for petrochemicals, synthetic rubber, and as blending stocks or fee
18、dstocks in the manufacture of motor gasolines. Its use as a fuel is generally limited to industrial applications where vaporization problems are not encountered, however, small quantifies are used as domestic fuel. Commercial Butane-Propane Mixtures cover a broad range of mixtures, which permits the
19、 tailoring of fuels or feedstocks to specific needs. Propane HD-5 is less variable in composition and combustion characteristics than other products covered by these specifications. It is also suitable as a fuel for internal combustion engines operating at moderate to high engine severity. Additiona
20、l Considerations Odorization For certain applications including, but not limited to, use of LP-gas for residential and commercial fuels, users of LP-gas should be aware of additional requirements of other standards, principally NFPA 58 “Storage and Handling of Liquefied Petroleum Gases“(1) and other
21、 regulations (2). NFPA 58 has been adopted widely by local, state and other regulatory bodies in the form of laws, ordinances, or regulations governing the safe storage, transportation, and use of LP-gas as fuels. iv Among other requirements, NFPA 58 (See. 1-4.1.1) stipulates that LP-gases “be odori
