Publisher Summary This chapter explains how various components are combined into a production system. The material is in no way meant to be all-inclusive. Many things must be considered in selecting components for a system, and there is no substitute for experience and good engineering judgment. A process flow sheet is used to describe the system. There are numerous figures that are typical of a flow sheet that will be used as examples for discussion purposes. Another name for a process flow sheet is a process flow diagram (PFD). Regardless of what it is called, either a flow sheet or a diagram, the information contained on it is the same. There are figures that define many of the commonly used symbols in process flow sheets. The study discusses the controlling process through operation of a control valve. Control valves are used throughout the process to control pressure, level, temperature, or flow. This section focuses primarily on the functions of this equipment; all control valves have a variable opening or orifice. With pressure control the study discusses that the hydrocarbon fluid produced from a well is made up of many components ranging from methane, the lightest and most gaseous hydrocarbon, to some very heavy and complex hydrocarbon compounds. Because of this, whenever there is a drop in fluid pressure, gas is liberated. Therefore, pressure control is important.
