High pressure stations

Digital Team — Thu, 04 Mar 2021 11:29:00 +0000

Natural gas is usually highly pressurized as it flows through transmission pipelines, but once it reaches the consumers, it needs to be brought up to the contractual specifications for delivery. This often means that in high pressure stations solids and liquids have to be filtered out, the pressure has to be reduced, and the gas may need to be preheated to compensate the cooling effect of the pressure reduction (Joule-Thomson effect). Moreover, the downstream consumers need to be protected for over-pressurization from the transmission line.
An accurate pressure control is the main contributor to the smooth flow of gas into transmission lines. The wide range of models allows to choose always the most suitable product for each application, because 80 years of experience in the field tell us that not all applications have the same maintenance and silent operations.

Gas metering

Digital Team — Thu, 04 Mar 2021 11:26:20 +0000

Gas metering stations are located along gas distribution and transmission networks. These stations allow pipeline operators and local distribution companies to monitor, manage, and account for the natural gas flowing through the network.
The main scope of a gas metering station is to measure the flow of gas, allowing distribution companies to manage the network and gas sellers to allocate and bill the consumption.
The flow rate through a station can be measured by means of different devices such as rotary, turbine and ultrasonic meters and orifice fittings. They record the flow rate in actual cubic meters and a volume converter calculates the equivalent compendated for pressure, temperature and density.

HIPPS

Digital Team — Thu, 04 Mar 2021 11:16:34 +0000

High Integrity Pressure Protection Systems (HIPPS) by Pietro Fiorentini are mechanical and electrical solutions designed in order to reduce the chance that the pressure will exceed the tolerable allowable level.
These systems are used in the Oil & Gas industries to provide pressure protection of pipelines, piping, vessels and process packages against over pressure, allowing the use of lower design pressure downstream.
Compared to conventional overpressure protection design standards that are based on relief devices (relief valves and rupture disks) that discharge to atmosphere, HIPPS has the great advantage to allow lower pressure rating downstream and to avoid discharge of natural gas to atmosphere.

Gas dehydration units with fixed bed technology (molecular sieves and aluminas)

Digital Team — Thu, 04 Mar 2021 11:12:01 +0000

Water contained in natural gas has to be removed for various reasons: avoid hydrate formation and corrosion, and achieve the required dew point for liquefaction. Hydrate formation would lead to clogging of equipment and components. This free water phase might also contain portions of acid gas (H2S or CO2), thus increasing corrosion effects downstream: this is the reason why natural gas shall be dehydrated.
Gas dehydration units with fixed bed technology (molecular sieves and aluminas) can adsorb impurities by a solid desiccant. Dew points obtained by molecular sieve technology easily go beyond values achieved with Glycol or Low Temperature Separation (LTS) technology: water content achieved with this technology will be as low as 1 ppm vol.
Adsorbent media are usually molecular sieve beds 4A or 3A: the selection depends on gas composition (CO2 and H2S concentration), and required lifetime of the bed.
Typical applications of these systems are gas treatment plants upstream deethanizers and LPG recovery units upstream liquefaction units, or they can be used for re-injection into wells.

H2S removal units with solid bed technology

Digital Team — Thu, 04 Mar 2021 11:10:40 +0000

Before being sent to the transmission network, natural gas needs to be sweetened in order to meet the utilization standards: hydrogen sulfide (H2S) is an undesired chemical molecule because it may corrode pipelines, equipments and instruments.
H2S removal units with solid bed technology by Pietro FIorentini are very simple and reliable natural gas sweetening processes able to achieve a very fine purification with ultra-low contents of hydrogen sulfide. The element chemically reacts with a solid adsorbent, generating a stable solid and non-toxic product that can be easily and safely disposed of or even regenerated.

Gas purification by membranes

Digital Team — Thu, 04 Mar 2021 11:09:45 +0000

In gas purification, membranes are used to separate components in natural gas such as water, CO2 and hydrocarbons according to their permeabilities. Each gas component entering the membrane unit has a characteristic permeation rate that is a function of its ability to dissolve in and diffuse through the membrane.
The driving force for separation of a gas component in a mixture is the difference between its partial pressure across the membrane. As high pressure feed gas flows into the metal shell of the membrane unit, the fast components, such as water and CO2, permeate through the membrane.
This permeate stream is collected at a reduced pressure, while the retentate, i.e., the dry natural gas, leaves the separator at a slightly lower pressure than the feed.
Pietro Fiorentini offers this technology both in natural gas and in biogas purification applications.

The ball of the floating valve is mounted on a trunnion which supports the pressure load. The seats are spring energized and the body construction is one piece, made by forging or casting. The ball is inserted from the top and it’s possible to disassembly the valve in line.

Mainly used for high-pressure transmission systems and for medium pressure gas distribution networks, it can be used with natural gas and previously filtered non-corrosive gases.

The trunnion ball valves are Hydrogen Ready for NG-H₂ blending.

For the Pietro Fiorentini Group, valves are produced by TIV Valves, a Group company specialized in the production of valves based in Rescaldina (MI). For more information visit the website.

In the floating valve the ball is not rigidly held on its rotational axis and so is free to float between seats. Sealing is achieved by the action of the pressure, which pushes the ball against a seat and the body construction is two pieces, bolted joint, made by forging, forged or rolled bar.

Mainly used for high-pressure transmission systems and for medium pressure gas distribution networks, it is suitable for use with natural gas and previously filtered non-corrosive gases.
