A wide range of analysis instruments are used in the oil, gas and petrochemical industries. [1] [16] Chromatography – to measure the quality of product or reactants; Density (oil) – for custody metering of liquids; Dewpoint (water dewpoint and hydrocarbon dewpoint) to check the efficiency of dehydration or dewpoint control plant

A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)
Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. [1] Meanwhile, control engineering , also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors.
This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management systems, production management systems, digital twins.
Example of a continuous flow control loop. Signalling is by industry standard 4-20 mA current loops, and a "smart" valve positioner ensures the control valve operates correctly. The fundamental building block of any industrial control system is the control loop, which controls just one process variable.
Many different solvents are suitable, including sulfolane (C 4 H 8 O 2 S), furfural (C 5 H 4 O 2), tetraethylene glycol (C 8 H 18 O 5), dimethylsulfoxide (C 2 H 6 OS), and N-methyl-2-pyrrolidone (C 5 H 9 NO). Below is a schematic flow diagram of one method, involving extractive distillation, for extraction of the BTX aromatics from a catalytic ...
