PREFACE
As teachers of surface production facility design in petroleum engineering
programs at Louisiana State University and the University of Houston,
KenandIrealizedthatnosinglesourcecouldbeusedasatextinthisfield.
We found ourselves reproducing pages from catalogs, reports, and projects
wehaddonetoprovideourstudentswiththebasicinformationtheyneeded
to understand our lectures and carry out their assignments. More impor-
tantly, the material that did exist usually contained nomographs, charts,
and rules of thumb that did not refer to the basic theories and underlying
assumptionsuponwhichtheywerebased.AlthoughVolume2oftenbuilds
uponinformationthatwaspresentedinSurfaceProductionOperations,Vol-
ume 1: Design of Oil-Handling Systems and Facilities, it does present the
basic concepts and techniques necessary to select, specify, and size gas-
handling, conditioning, and processing equipment. After the initial release
ofthefirsttwovolumes,werealizedthatmanytopicsneededtobecovered
inmoredepth.Asaresult,threeadditionalvolumeswereaddedtotheseries,
tobepublishedatalatertime.Volume3coversthedesignoffacilitypiping
and pipeline systems, as well as relief and vent disposal systems; Volume 4
covers rotating equipment, specifically pumps, compressors, and drivers;
andVolume5coversinstrumentation,processcontrol,safetysystems,elec-
trical installations in hazardous (classified) locations, and project and risk
management.
Volume 2, which covers one semester’s work or a two-week short
course,focusesontheprocessesandequipmentinvolvedwithgas-handling,
conditioning,andprocessingfacilities.Theobjectiveofgas-handling,con-
ditioning, and processing facilities is to separate natural gas, condensate, or
oilandwaterfromagas-producingwellandconditionthesefluidsforsaleor
disposal.Specificareasaddressedbythisvolumeincludebasicprinciplesand
fluid properties, process selection, heat transfer and heat exchanger equip-
ment, hydrate prediction and prevention, condensate stabilization, com-
pression, dehydration, acid gas treating, and gas processing. As was the
case with Volume 1, this text covers topics that are common to both oil-
and gas-handling production facilities, such as surface safety systems.
Throughoutthetextwehaveattemptedtoconcentrateonwhatweper-
ceive to be modern and common practices. We have personally been
involved in the design and troubleshooting of such modern facilities
