INTEGRATING AND TRENDING USM, FLOW COMPUTER, AND CHROMATOGRAPH DIAGNOSTICS TO IDENTIFY MEASUREMENT PROBLEMS Today’s smart measurement devices produce significant diagnostics information. When the diagnostics from the various devices are collected, trended, and integrated, operators can remotely and continuously identify measurement problems. The vocabulary associated with this topic is evolving. In the past, the industry used terms such as SCADA and Condition Based Monitoring to describe this process. These…

GAS ODORANTS – SAFE HANDLING, HEALTH, AND ENVIRONMENT Thiols (i.e. mercaptans), sulfides, and tetrahydrothiophene (THT) have been widely used in the odorization of natural and liquefied petroleum gas due to the fact that natural gas does not possess an odor. Mercaptans, for example, have proven to be very effective in odorizing because of their low odor threshold and therefore, immediate impact on the…

FIELD INSPECTION AND CALIBRATION OF VOLUME CORRECTING D E V I C E S Timely, diligent field testing and calibration of gas volume recording and correcting instruments ensure that measurement information fairly represents actual volumes. The instruments save a company capital and operating costs because they can record or integrate volumes at pressures and temperatures above the normal pressure base conditions specified in contracts for volume calculation. This allows…

FUNDAMENTALS OF VOLUME MEASUREMENT (TURBINE METERS) Turbine meters have been used for the custody transfer of refined petroleum products and light crude oils for over 40 years. When correctly applied, they offer high accuracy and long service life over a wide range of products and operating conditions. Traditionally turbine metes were used for the measurement of low viscosity liquids and PD…

FUNDAMENTALS OF NGL SAMPLING SYSTEMS The purpose of this paper is to discuss in depth the systems we use as a standard to sample natural gas liquids, or NGL’s. Before we discuss the systems and methods used to sample these products, we must first clearly define what NGL’s are. NGL’s can be a combination of any fluid in liquid form…

FUNDAMENTALS OF NGL METER STATION DESIGN This paper provides a fundamental overview of an NGL meter station design reviewing the nuances of configuring similar components in different ways. There are multiple considerations that influence the meter station design and all must be taken into account. Major considerations are: what product or products will be measured, what meter technology to utilize, and…

FUNDAMENTALS OF NATURAL GAS LIQUID MEASUREMENT The measurement of natural gas liquids (NGL) is similar in many respects to that of other hydrocarbon liquids but is markedly different in other aspects. The main difference in NGL measurement is the need to properly address the effects of solution mixing. Measuring NGL by mass measurement techniques will properly address solution mixing effects because…
