AIR SEPARATION PLANTS

HIGH PURITY SOLUTIONS

INTRODUCTION

Cryogenic air separation plants are suitable for the production of liquid and / or gaseous oxygen, nitrogen and argon. The precious products are derived from atmospheric air, based on a low-temperature rectification process with high purity and widespread applications in industrial and medical sectors.

CRYOGENIC AIR SEPARATION

The raw material for air separation is atmospheric air with its main constituents: nitrogen, oxygen and argon. The air separation is based on the cryogenic rectification process, in which the compressed air is cooled down to -195 °C and partially liquefied. The rectification separates the individual constituents of the air by means of their differing boiling points. The gases / liquids are then available in the highest purity.

CO2 TECHNOLOGIES FOR THE CHEMICAL, POWER AND FOOD INDUSTRY

INTRODUCTION

Anglo Euro Energi Indonesia has selected and appointed Cryotec GmbH for the construction and delivery of CO2 plants from a single source, where the various components are optimally matched to each other and perform extremely efficiently. The CO2 plants can be erected pre-assembled on base frames or in containers and are suitable for both indoor and outdoor installation. The prefabricated units enable a shortened assembly / commissioning time onsite.

Cryotec carbon dioxide plants are fully automated, capable in dealing with large volumes with low operation costs. AEEI is able to offer competitive plant solutions and efficient plant operation and the CO2 Purification and / or Recovery produces high product purity.

After commissioning, staff training is provided by Anglo Euro Energi and operations and maintenance of the plant are monitored by remote access to ensure optimal performance.

CO2 recovery, purification and liquefaction plants provide the most efficient solution to process carbon dioxide for usage in breweries, chemical plants or dry ice production.

SOME CO2 APPLICATIONS

CO2 EXTRACTION

There are natural gas fields with a very high CO2 concentration particularly in the vicinity of volcanic regions. This CO2 can be cleaned, processed and utilised for conversion to commercial products.

FOOD QUALITY CO2

The CO2 recovered from fermentation processes is particularly suitable for producing food quality CO2.

CO2 FROM INDUSTRIAL APPLICATIONS

Large quantities of carbon dioxide evolve from many industrial processes, for example combustion and other chemical processes. The CO2 can be recovered and made available for use in various Industrial sectors.

BIO — CO2

The carbon dioxide produced by biogas plants is often allowed to go to waste. Cryotec has the technology to extract this carbon dioxide, and prepare it for various uses (i.e. as a “fertiliser” in greenhouses, food industry). Using carbon dioxide separated from biogas and liquid biomethane can make existing plants operate more efficiently resulting in improved profit and environmental performance.

LNG TO POWER

AEEI is collaborating with CRYOTEC for LNG to Power projects internationally.
AEEI is focusing on securing sources of natural gas from natural gas producing wells both onshore and offshore.

The offshore gas shall be delivered via pipeline to onshore locations where our liquefaction plant shall be located to process the natural gas into LNG to be transported and distributed to customers at nearby industries.

For onshore site locations, methane shall be processed for power generation to replace diesel generators.

SATELLITE STATIONS

Natural gas is an increasing reliable source for energy supply. Diesel-powered back-up systems can be replaced by Gartrellite stations.

Switching fuel supply to LNG enables clean and efficient energy generation. Gas-fired Power Plants emit lower CO2, NOx, SO2 and other particulates.

LNG eradicates the need to connect to a pipeline as the satellite station is fuelled by tanker. An LNG infrastructure can be implemented as a back-up system for large gas turbine power plants.

BOIL – OFF GAS HANDLING

Solutions from CRYOTEC can recover the boil-off gas from LNG storage tanks and convert it back into usable form. This boil-off gas can be reliquefied, and fed back into the LNG tank or transformed into electrical energy.

SMALL – SCALE LIQUEFACTION

Small-Scale Liquefaction enables production of small natural gas fields for commercial operations. Natural gas can be processed and liquefied directly at source or at pipeline terminal for transportation and distribution.

APPLICATIONS FOR ENERGY SUPPLY

Reliable constant supply of LNG for independent power generation.

Constant supply systems
Provide a completely independent power supply derived from LNG.

Peak load systems
Designed to make up for supply shortages during peak load times (winter, increased production, etc.)

Back-up systems / emergency systems
Designed to ensure the continuity of plants operation in the event of a power outage or loss of the gas supply.

SMALL – SCALE LNG LIQUEFACTION MODULE

Natural gas is a clean fuel for the future with a 25% reduction in CO2 emissions, 90% reduction in NOx emissions, and 100% reduction in SO2 and fine particle emissions. LNG is in great demand globally and is often considered as a transition fuel.

The liquefaction of natural gas into LNG ensures a flexible, independent supply in contrast to transporting gas by pipeline. Methane is the main constituent of natural gas.

Natural gas is cleaned and dried, carbon dioxide and water are removed before it is liquefied. The multi-stage cryogenic process developed by CRYOTEC cools the natural gas down to its liquefaction point. The liquefied natural gas can then be stored or transported in ISO tanks or special containers.

BENEFITS OF LNG

• LNG is a sustainable, commercially viable alternative to diesel fuel and has widespread applications in the power, transportation, and industrial sectors
• LNG has great potential for reaching the 1.5°C target of reduced greenhouse gases and improved air quality due to fewer emissions of particulate matter, sulphur, nitrogen oxide and CO2
• The advantage of the liquid state of natural gas is its very high energy density and very high energy content, which allow the long ranges that are particularly important for long-distance freight transport: Ranges of 1,000km and more can be achieved with just one tank of fuel
• Efficient energy storage : 1m³ LNG ≃ 600m³ Natural gas
• LNG is non-toxic and non-corrosive

LNG SUPPLY CHAIN

LNG REGASIFICATION

Regasification plants enable energy providers to cover peak periods of natural gas consumption. This involves re-evaporating the liquid natural gas and feeding it into the supply network or used for generating heat or power. The cold energy in the LNG released by the re-evaporation can also be put to good use for cooling or freezing purposes.

LNG REGASIFICATION PLANTS

In the LNG tank farms, the cryogenic, liquid natural gas is stored in double-walled, vacuum-insulated tanks. The atmospheric evaporators transform the liquid natural gas into its gaseous form, that can then be fed to where it will be used. The plant equipment in these satellite stations have proven to be reliable overtime in the field of technical gases.

LNG APPLICATIONS

LNG AS FUEL

Liquefied natural gas (LNG) is gaining importance as a fuel. Its environmentally friendly combustion and many possible uses are helping to make LNG a success. Particularly in urban areas and ports, liquefied natural gas is a recognised alternative to conventional fuels as it significantly improves the air quality by reducing emissions.

Bio LNG is an environmental alternative that can be considered where sufficient raw materials are available from agricultural or industrial sources.

LNG FILLING STATIONS

CRYOTEC supplies and constructs turnkey LNG filling stations. These filling station systems are designed, engineered, constructed and installed either as a mobile system solution (skid-mounted, containerised) or as a stationary tank farm. Filling stations are designed to refuel vehicles, buses and trucks towards sustainable clean energy usage.

SHIPPING

In many ports, emission limits are already put into practise in order to improve the air quality of the neighbouring towns and cities. In the shipping industry, liquid natural gas is establishing itself as an alternative propulsion technology. CRYOTEC develops and designs LNG tank storage facilities and refuelling stations for the marine sector.

BIO – LNG

The liquefaction of biomethane from biogas plants is an excellent technology for storing energy and delivering it again when it is needed.

Biomethane can be stored by the liquefaction process, and then transported to the end user.

A better environmental balance can be achieved by adding biomethane to fossil natural gas. If the biogas is cleaned to natural gas quality (or better), it can be fed into the natural gas network.
