It is necessary to importantly measure or ascertain this parameter, since the flow rate is critical in many industrial processes, especially in chemical industries. Static Head – The difference between the inlet tank fluid surface elevation and the discharge tank fluid surface elevation.
A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale. [1] The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials. [ 2 ]
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. [3] [4] [5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency [6] while the composition must be disclosed if the regulator demands it.

Chemical – abrasive/reactive: pickling in liquids, plasma-assisted, sputter-cleaning, electropolishing; Chemical – non-reactive: organic solvents, aqueous solutions, supercritical CO 2; The contamination layer may then be further classified according to: Origin; Composition: e.g. cooling lubricants may be composed differently. Single ...
This convention applies to all branches of economy, in which chemicals are used. After an assessment of the hazards involved and protective measures to be applied, an organization may be exempted by the competent authority of a member if special problems are encountered, sufficient protection is provided, or precautions taken to protect confidential information do not compromise the safety of ...
Liquid fluids are composed of natural and synthetic material in a mixed state, [1] which can be of two types: [2] Aqueous; [3] usually with substances added that control viscosity, along with lubricants, for the inhibition of corrosive inhibitors, salts, and pH-control agents. [1] Oil; which could be usually using hydrocarbon oil, [1]
An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [2]
Process Safety Management of Highly Hazardous Chemicals is a regulation promulgated by the U.S. Occupational Safety and Health Administration (OSHA). [1] It defines and regulates a process safety management (PSM) program for plants using, storing, manufacturing, handling or carrying out on-site movement of hazardous materials above defined amount thresholds.
