One of the priority trends in development activities оf Cryogenmash is elaboration of new original cryogenic technologies and creation of the equipment for liquefaction of natural gas, for its storage, transportation and usage.

Creation of the equipment for LNG is being carried out at Cryogenmash since 1980s.

Cryogenmash, using its capabilities and experience, is proposing to elaborate, manufacture and deliver to Customer a complex of the indispensable cryogenic equipment for implementation of the LNG technologies with fulfillment of mounting and commissioning works, as well as training of personnel.

CRYOGENIC EQUIPMENT FOR LIQUEFIED NATURAL GAS (LNG)

• The LNG plants are based on refrigerating and cryogenic cycles, with use of energy-saving technologies, with use of gas pressure difference power at gas-distribution stations; an estimated capacity range is from 0.4 to 10 tons of LNG per hour; the specific power consumption is from 0 to 1 kWhr/kg of LNG.
• LNG storage systems on the basis of modular systems (БСХП), factory-ready for operation, with use of cryogenic reservoirs with screen-vacuum superinsulation. The БСХПs are also available in volumes from 5 to 100 m³. The LNG reservoirs 250 m³ in volume are also made.
• Truck-mounted LNG tanks Type ЦТП with screen-vacuum superinsulation for transportation of liquefied natural gas. The tanks are made in volumes of 8 and 25 m3 and are designed for operating pressure 0.6 MPa. They provide non-drainage storage of LNG during 7-10 days.
• LNG gasification systems designed for various volumes of LNG storage, with capacities ranging from 100 to 2000 m³/hr; gasification of LNG and heating of gas are effected in ambient evaporators with delivery of gas at the temperature that is by 15÷20 degrees lower than the ambient temperature.
• Vehicle-borne fuel systems with the tanks of volumes from 90 to 560 liters for use of LNG in motor transport.
• Transport gasification systems of volumes from 20 to 100 m³ for LNG use in railway transport.
• Units for integrated front-end-purification of natural gas from carbon dioxide and for removal of moisture from gas.
• Automated control and monitoring systems (ACMS) intended to automatically control and monitor the processes of conditioning, liquefaction and storage of LNG.

Note:

The liquefied natural gas is a promising and ecologically safe energy carrier of the XXI-th century – a cryogenic liquid with methane content of not less than 86% by volume (TY (technical specifications) 05-03-03-85) and at boiling temperature from minus 162°C. At re-gasification from 1 m3 of LNG, produced is about 600 m³ of gas under normal conditions (760 mm Hg., 0°C).

LNG is a perspective energy carrier and provides economical and ecological efficiency in relation to other fuels.

For Russia now, actual and perspective is the creation of LNG production and implementation of diverse technologies with usе of LNG.

The implementation of efficient cryogenic technologies with use of LNG allows:
- to supply gas to objects (boiler-houses, human settlements), that are far away from gas-distributing systems;
- to create a reserve stock of LNG fuel with its further re-gasification and feed to Consumer;
- to carry out the conversion of road, air, railway and river transport to gas fuel with use of LNG as a vehicle-borne reserve.

LNG is used as a fuel for autonomous heating of industrial objects and the human settlements that do not have pipeline gas supply. Potential Customers: municipal services of thermal power stations, small enterprises, rural boilers, municipal boiler-houses, the mini-cogeneration stations, autonomous electricity generating plants, motor transport companies; railway transport; air carriers corporations, etc.

The liquefaction plants are not of standard type, since the schematic diagrams and the components of the equipment are specified depending on a set of the parameters specific for particular objects: pressure of gas, its composition, the contents of valuable and harmful impurities, the presence of moisture and solid impurities. Selection of a cycle is effected at the stage of the technical and commercial proposal development. The specific power consumption and the cost of the equipment depend on a selected cycle and basic data.

In order to take into account the Customer's requirements, a questionnaire has been issued specifying the components of the equipment for a LNG complex. For detailed information on LNG technologies, please, fill out the questionnaire and send it to our address. Upon obtaining the questionnaire and after studying it we are ready to prepare a technical and commercial proposal for the LNG equipment under consideration.

The gasification systems based on БСХП and ambient evaporators made by Cryogenmash, just within several years are being successfully operated, using LNG, in Leningrad region for gasification of boiler-houses in settlement Krasny Bor, in Nikopol city and at Luzshsk tinned milk food factory, etc.

CRYOGENIC EQUIPMENT FOR PROCESSING NATURAL, ASSOCIATED AND REFINERY GASES

Cryogenmash is in a position to develop, manufacture and supply the complete sets of the plant equipment, process lines and units for processing hydrocarbon gases, including nitrogen-, helium-, argon- and hydrogen-containing mixtures. The commercial products of such plants include: liquid and gaseous helium, hydrogen, nitrogen, argon, ethane, propane-butane mixtures, propylene, butanes, fuel gases, also natural gas or LNG, extracted from petroleum associated gases, etc., that conform to State Standards (GOST), Branch Standards, Technical Specifications, Company's Standard, or to technological purposes upon Customer's request.

The low-temperature separation technology used by Cryogenmash allows to carry out more deep recovery of commercial products as compared to existing technologies.

The advantages of the schemes with use of low-temperature distillation of gases should be attributed to reaching of high recovery coefficients, for example, for propane - up to 95% by volume, even from hydrocarbon mixtures of gases even with its low content (about 1% by volume).

The estimated capacities of the plants for the gas being processed are as follows:
from 3000 to 150000 Nm³/hr (25 to 1400 mln/ Nm³/year).
Upon request, it is possible to receive more detailed information regarding expediency and practicability of implementation of our cryogenic technologies in gas separation for particular conditions; please, fill out the questionnaire and send it to our address (ГРУ).
