Liquid distillation system

Liquid distillation system

Distillation is a process of separating the component substances from a liquid mixture by selective vaporization and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility […]

Sulphur recovery plant

Sulphur recovery plant

Sulfur is a component of coal and other gasification feed stocks. Resulting sulfur compounds in syngas need to be removed in most gasification applications due to environmental regulations or to avoid catalyst poisoning. Whether it is electricity, liquid fuels, or some other product being output, sulfur emissions are regulated, and sulfur removal is important for […]

Vapour recovery system

Vapour recovery system

Vapor (or vapour) recovery is the process of recovering the vapors of gasoline or other fuels, so that they do not escape into the atmosphere. This is often done (or required by law) at filling stations, in order to reduce noxious and potentially explosive fumes and pollution. The negative pressure created in the (underground) tank […]

Oily water treatment

Oily water treatment

Solids and oil separation technologies have been used across a range of applications, at installations both onshore and offshore. Including: • Produced water – recovered during the separation of crude oil. • Desalter water – generated during crude oil washing. • Ballast water – for incoming sea tankers. • Terminal and refinery process drainage – […]

Waste water treatment

Waste water treatment

wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Most industries produce some wet waste although recent trends in the developed world have been to minimise such production or recycle […]

Dew point control

Dew point control

Hydrocarbon dew point refers to the temperature at any pressure range or the pressure at any temperature range where hydrocarbons begin to condense from the gas mixture. At the same temperature, heavier hydrocarbons’ dew point temperature increases as the pressure is reduced. Hydrocarbon dew point control (HCDPC) can be used for the extraction of NGL […]

Glycol reclaiming

Glycol reclaiming

Large glycol reclamation plants that recover mono-ethylene glycol (MEG) used for hydrate inhibition typically apply flash vaporisation under vacuum to remove dissolved and suspended solid contaminants. Heat is transferred to the salty rich glycol feed at the lowest possible temperature by direct contact with hot recycled liquid, followed by distillation to recover clean salt-free reconcentrated […]

Molecular sieve

Molecular sieve

Molecular sieves are crystalline metal aluminosilicates having a threedimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size. A 4 to 8-mesh sieve is normally used in gasphase applications, while the 8 to 12-mesh […]

Teg regeneration

Teg regeneration

Most natural gas producers use Triethylene glycol (TEG) to remove water from the natural gas stream in order to meet the pipeline quality standards. This process is required to prevent hydrates formation at low temperatures or corrosion problems due to the presence of carbon dioxide or hydrogen sulfide (regularly found in natural gas). Dehydration, or […]

Meg regeneration

Meg regeneration

Monoethylene Glycol (MEG) is used regularly in the oil and gas industry to prevent the formation of hydrates and resulting blockages in pipelines and equipment. To reduce costs and the quantity of wasted MEG, MEG is often regenerated. Hydrate formation becomes more frequent at low temperatures and high pressures, making subsea pipelines particularly vulnerable to […]
