API MPMS Chapter 1 1.l-2004/Adlunct to AS’TM 01250-04 and IP 200/04 provides general procedures for the conversion of Input data to generate the corrected values at the user specified bate temperature and pressure using the effect of temperature on the liquid (Cit.). the compressibility coefficw.iit (F,). the correction foe the effect of pressure on the liquid (CPI.). or the correction for temperature and pressure of a liquid (CTPL), in a form that is consistent with the computation procedures used to generate VCF values. Two sets ad procedures are given for computing the volume correction factor: one set roe data expressed in U.S. customary units (temperature in degrees Fahrenheit. pressure in pounds per square inch gauge), the other for the metric system of units (temperature In degrees Celsius, prelature in kilopascals). In contrast to API MPMS Chapter 1 1.1.1980/ASTM D1250.80/IP 200/80. the metric procedures require the procedure for U.S. customary units be used first to compute density at 60 F This value is then further corrected to give the metric output. For density/weight/volume intraconverslon, reference shall be made to API MPMS Chapter 11.5 Part ito Part 3/Adjunct to ASTI4 01250-08 and IP 200/08. These standards provide conversion of riicasureinents ri-urn one system of units to another fur both in vacua and In air values. For NGL and L.PG. reference shall be made to Al’l MPAIS Chapter 11.2.4 .2007/(;PA Technical Puhlkat Ion TP-27.2007. The implementation procedures describe how to cakulate the CTL given an appropriate density factor at bjsis temperature and an observed temperature, and calcubte the appt’opnate density factor at basis temperature given a relative density at an observed temperature. The implementation procedures are presented In pairs by base temperature. First, the procedures for Tables 23K and 24E of API MPMS Chapter ii.2.4.2007/GPA TP-27’2007 at a 60 F base temperature are given. The procedure for table 23K makes use of the procedure described in Table 24K. thus Table 24K Is presented first. These are followed by procedures for Table 54K and Table 53K at a base temperature of 15 ‘C, which themselves make use of the procedures in Table 23K and Table 24K; thesc In turn are followed by the procedures for Table 60K and Table 59K at a base temperature of 20 ‘C, which also make use of...
