Technical designation for a pipeline that lies above the soil surface

Old spelling for ethylene

Alarm and Emergency Plan

The Alarm and Emergency Plan is used to control and limit damage, so that impact can be kept to a minimum and any damage to people, the environment and property is limited. In addition, it serves to control information flows and measures when dealing with exceptional events, and to prevent or limit the resulting impact to people, the environment and property.

Area “Antwerp / Rotterdam / Amsterdam” in particular with regard to port activity

BImSchG (German Federal Emissions Protection Act)
Abbreviation for Federal Emissions Protection Act, which regulates and controls harmful influences such as air, water, or noise in the framework of environmental legislation for the environment.


Common Carrier
„Common Carrier“ means that, depending on available pipeline capacity, any consumer, producer or third party can contract ethylene transport subject to a standard product specification, general pipeline transport conditions and a public tariff system.

CP (cathodic protection):
Cathodic protection (CP) is an active system to prevent corrosion to pipelines. It is based on a DC power source (low current) that prevents electrochemical processes of corrosion on pipelines. The system is used worldwide in pipeline construction as well as ships, port facilities or any components in humid atmospheres. CP also allows accurate positioning of any defective spots in the pipeline insulation.

Process by which hydrocarbon molecules are broken down at temperatures of over 800° Celsius.

Crude oil
Naturally occurring mixture of hydrocarbons that includes compounds of different molecular sizes.

Crude petroleum
Untreated oil distillate as raw material for the petrochemical industry (naphtha).


High-quality processing products from crude oil.



Release of gaseous, liquid or solid substances


Are the production and discharge of something that has an effect on the biosphere (humen, animal, plant, soil, warter)

Ethylene Pipeline South (EPS); pipeline from Ludwigshafen to the Bavarian chemical industry

Chemical formula C2H6, after methane the second most common atmospheric trace gas from the group of hydrocarbons.

Also ethylene monomer, ethene: Ethylene is a simple reactive hydrocarbon containing two carbon atoms; it is used by the petrochemical industry among other things for the production of polyethylene, polyvinyl acetate and polyvinyl chloride (PVC); colourless, slightly sweet-smelling gas that is lighter than air under normal conditions. Chemically, ethylene is composed of two carbon and four atoms of hydrogen. Ethylene boils at -104 °C and 1 bar; ethylene is always gaseous at atmospheric pressure and a temperature range of -30 °C to + 30 °C.

Ethylene pipeline
The line was put into operation in 1976, complies with all current technical safety requirements and corresponds to the state of the art. It is regularly inspected from ground and air (helicopter).


Fluid is a collective term for all gaseous (gas) and liquid (fluid physics) states of matter.


A state of matter in which the individual molecules are relatively mobile.

A state of matter, is one of the distinct forms that matter takes on, which can transform into each other by mere changes of temperature or pressure. There are the three fundamental states of matter: solid, liquid, and gas.


Are the production and discharge of something that has an effect on the biosphere (human, animal, plant, soil, water)

Totality of all basic facilities, including personnel, material and institutional resources, that ensure the functioning of an economy. Colloquially, the term is often equated to transport links (land, rail, air), but can also designate energy or commodity pipelines, or telecommunication backbone pathways.


Joint venture
Joint enterprise undertaken by two otherwise independent company, for example through the establishment of a subsidiary company in the hope of profitably merging their knowledge and skills.




(LDS) Leakage Detection and Localization System
This system is used for monitoring pipelines, tank farms and chemical plants and detects leaks/faults at an early stage. The leak position is captured as precisely as possible using different measurement and detection techniques.


This is an untreated petroleum distillate, which is used as a raw material for the petrochemical industry (crude petroleum).

Natural gas
Collective term for hydrocarbon gas mixture consisting primarily of methane; its other components include ethane, propane, nitrogen, and carbon dioxide; it is primarily used as fuel.




Petrochemical industry
Petrochemical (also petroleum chemistry; after (Greek.) petros = rock and (Latin) oleum = oil) refers to the production of chemical products from natural gas and appropriate fractions of crude oil.

Pig (Pipeline Inspection Gauge)
A pig is a mobile operating and monitoring device that is basically used to clean, seal after repairs and check for corrosion and cracks inside the pipeline.

Pigging is a process by which a pipeline is checked from the inside with a “mobile mini lab” that traverses the pipeline over its entire length. The device collects a wealth of data that enable a precise analysis of the pipeline wall. The measured values enable calculation of wall thickness at every point and detection of defects such as corrosion spots so that appropriate measures can be taken.

Tubular line required to transport liquids or gases over short or long distances.

Pipeline routing
The area required for laying a pipeline system. It describes how to design and determines the layout of a roadway in terms of position, height and cross section.

Pipeline transport tariff / Pipeline transport tariff system / Pipeline transport fees
Fixed tariff system that regulates the pipeline transport charges for all connected organizations / feeders. ARG’s pipeline transport tariff comprises a fixed Basic Rate(Basic Rate) and a variable element, the distance-related Pipelining Rate.

Chemical compound; composed from same or similar low-molecular basic components (monomers).

Polyvinyl chloride
Abbreviation PVC: Thermoplastic plastic produced by polymerisation of vinyl chloride.

A gaseous hydrocarbon from the group of alkenes.


Processing plant that produces marketable petroleum products from crude oil.

Stock of assets such as capital, real estate, personnel and consumables. The amount of resources is always restricted, or limited, even if available in very large quantities.

The “abstract” way or course followed by roads, railways etc. The course of supply and disposal pipelines is also called route.

ROV (regional planning procedure – Raumordnungsverfahren)
Multidisciplinary coordination for projects of supra-regional significance. A procedure that basically endeavours to balance the needs of people and the environment against the benefits and risks of each project in order to establish the requirements for the project. The aim is to balance the interests of stakeholders on site.


Service Provider
Technical service provider of ARG mbH & Co. KG: petrochemical pipeline services B.V. (PPS) and Evonik Technology & Infrastructure GmbH.

Steam cracking (also olefin cracker)
Process (see also cracking) applied in the petrochemical industry primarily for the production of unsaturated gases (e.g. ethylene). The steam cracking process enables the production of chemical raw materials by using steam from petroleum products.

Above the so-called critical pressure and critical temperature, materials take on special physical properties that are not typical of fluids or gases. Also referred to as “dense phase”. Ethylene is transported in pipelines in the gas phase, whereby the density of the gas is closer to the density of liquid.
