Introduction to high-efficiency and low-cost small natural gas liquefaction plants

（ WSCE-MiniLNG series)

Harbin Institute of Technology and Harbin Institute of Technology Xuebei Cryogenic Equipment Co., Ltd. have jointly developed a small, efficient, low-cost natural gas liquefaction plant equipment: WSCE-MiniLNG series liquefaction plant equipment. The WSCE-MiniLNG liquefaction plant can be installed anywhere where natural gas is available. Whether it is coal bed methane, oil field gas, refinery waste gas or biogas, it can produce LNG. It can also directly draw gas from the urban natural gas pipeline network to produce LNG.

WSCE-MiniLNG liquefaction plant has the advantages of low cost and small floor space. Traditional natural gas liquefaction plants are large in scale, often requiring investments of tens or even hundreds of millions of yuan, covering an area of ??dozens of acres, and have to go through long and complex approval procedures at the national and local governments. The WSCE-MiniLNG liquefaction plant produced by Xuebei Company only has an investment of 2 to 5 million yuan, can cover an area as small as 25 square meters, and can produce 1,000 to 3,000 standard cubic meters of liquefied natural gas every day. A liquefaction plant with a daily output of 3,000 standard cubic meters of LNG can supply gas for 100 taxis, 25 buses, 15 large trucks, or 6,000 urban residents.

WSCE-MiniLNG liquefaction plant can adapt to different conditions of various gas sources. The liquefaction plant equipment adopts modular, skid-mounted and even vehicle-mounted designs. Equipment size, type and quantity can be combined according to actual needs. Due to its small and compact vehicle-mounted design, this completely new type of mobile liquefaction plant can travel between different gas sources and is not limited by the life of the gas source or geographical location. It is especially suitable for scattered small gas sources, especially those single well coal bed methane and oil field flare gas that are small or difficult to connect to the pipeline network. It can also recover waste gas from petroleum refineries or oil field associated gas during equipment maintenance. According to needs, this small vehicle-mounted liquefaction plant can also be accompanied by an LNG tanker with a capacity of 20 cubic meters, and can be loaded and transported while liquefying. Since all liquefaction equipment is mass-produced in professional chemical plants, the quality of the equipment is not only guaranteed, but the cost is also greatly reduced.

WSCE-MiniLNG liquefaction plant creates convenient conditions for the promotion and use of natural gas vehicles. Currently, many cities are using pipeline natural gas to produce high-pressure natural gas (CNG) for taxis. However, a 50-liter high-pressure gas cylinder can only power taxis for more than 100 kilometers. In addition, the number of CNG filling stations is scarce, which seriously affects the use of natural gas vehicles. Promote use. Using liquefied natural gas (LNG), the same 50-liter volume can run 400 kilometers.

WSCE-MiniLNG liquefaction plant is more suitable for large fleets traveling long distances. For those large long-distance truck fleets or long-distance bus fleets with fixed transportation distances, including coal transport fleets, you can build a WSCE-MiniLNG liquefaction plant in a nearby gas source to specifically refuel the fleet. The economic superiority of LNG vehicles over diesel vehicles is quite prominent: according to the current market price of 300L of LNG, it is 619 yuan, which is equivalent to 177 liters of 35# diesel. The current market price of 35# diesel is 5.87 yuan/L, which is 1,039 yuan. It is 420 yuan more expensive than using natural gas. If the truck uses a 300-liter bottle of LNG every day, it can save NT$12,600 per month. 300 liters of LNG can drive a large truck 400 kilometers.

The WSCE-MiniLNG liquefaction plant also creates convenient conditions for the use of natural gas in remote towns and residential areas far away from long-distance pipelines. Currently, many urban residents who are far away from natural gas pipeline networks or sources cannot enjoy the benefits of using natural gas as a domestic fuel.

A small liquefaction plant that can produce 3 cubic meters of liquid LNG per day is equivalent to 1,875 standard cubic meters of natural gas in standard conditions. If calculated based on the standard daily gas consumption of 0.5 standard cubic meters per household, it can supply 3,750 households with natural gas for one day. If we take the 1,500 standard "socialist new rural" residential areas being built across the country as an example, only 750 standard cubic meters are needed every day. Therefore, one gas supply station has a rich gas supply coefficient of 2.5 times, or two " "New Countryside" provides gas at the same time. In addition, Fuyu's liquefied natural gas can also be used to expand the user market or be combined with natural gas vehicle filling stations. If residential gas supply stations and taxi gas filling stations are jointly supplied, in addition to supplying gas to 1,500 residential communities, Fuyu LNG can also refuel 33 LNG or 100 CNG taxis every day.

At present, some gas companies use liquefied petroleum gas (LPG) to supply gas to residents in residential areas. Taking 1,500 households as an example, they use 750 standard cubic meters of natural gas per day, totaling 2,475 yuan, which is equivalent to 1,080L of LPG. If the residential area Calculated based on the market LPG price of 3.75 yuan/L, it is equivalent to a daily LPG gas fee of 4,050 yuan. Therefore, after building a WSCE-MiniLNG liquefaction plant, the use of LNG can save 1,575 yuan per day, 47,250 yuan per month, and 56.7 yuan in gas fees per year. Ten thousand yuan. It is safer and more environmentally friendly for residents to use LNG than LPG.

Due to the scarcity of LNG, some city gas companies have to use high-pressure cylinders to deliver natural gas to residential areas. To transport 200 standard cubic meters of natural gas, use CNG normal temperature and high pressure cylinders with a diameter of 350mm and a length of 1800mm. A minimum of 11 are needed and a weight of 1150 kg. The equivalent LNG cylinder only needs one low temperature and normal pressure cylinder with a diameter of 650mm and a length of 1600mm. cylinder, weighing only 290 kilograms. In addition, similar to CNG car gas stations, it is difficult to store CNG in residential gas supply stations. If LNG is used, a 1 cubic meter LNG cylinder can meet the gas needs of 40 households for a month. LNG in these remote towns can be provided by a WSCE-MiniLNG liquefaction plant built at any natural gas gate station with a natural gas pipeline network within a few hundred kilometers, or by a coal bed methane, oil field gas or biogas gas within a few hundred kilometers. A WSCE-MiniLNG liquefaction plant will be built near the source to provide it.

WSCE-MiniLNG liquefaction plant has the advantages of high adaptability and mobility. It can be transferred to another well to continue producing LNG immediately after one well is depleted. A vehicle-mounted container-type WSCE-MiniLNG liquefaction plant can be a self-contained system without external water supply and electricity, and the operation of the plant can be fully supported by a small natural gas generator. Thanks to the advanced automation design, the daily operations of the liquefaction plant can be monitored and operated remotely. Therefore, apart from security and anti-theft reasons, the liquefaction plant basically does not require routine maintenance.

A WSCE-MiniLNG liquefaction plant with a daily output of 3,000 standard cubic meters has annual sales of more than 3 million yuan. This kind of small natural gas liquefaction plant can immediately turn those closed gas wells that are not suitable for large-scale development into cash cows. Many domestic gas-producing areas are in economically underdeveloped areas. Over the years, even though the state has relaxed some unified management policies in gas-producing areas in order to develop local economies, because local natural gas resources cannot be exported to other places, the gas-producing areas have always been left to their own devices. On the Jinshan Mountain, you can only envy others to get rich. The equipment cost of the WSCE-MiniLNG liquefaction plant produced by Xuebei Company is very low, only a few million, and even individuals can invest in building the plant. Due to the scarcity of LNG, someone will immediately come to you to underwrite the LNG produced. This provides a tool for flexible and rapid development and utilization of local resources and rapid revitalization of the local economy in gas-producing areas. With this tool, some coalbed methane, oil field flare gas or biogas that is stored or even vented to pollute the atmospheric environment can be developed and utilized.

The Institute of Low Temperature and Superconducting Technology of Harbin Institute of Technology and Xuebei Company independently developed a series of large, medium and small natural gas liquefaction technologies, filling the gap in MRC liquefaction technology in China and taking the lead in building the The first industrial-scale MRC natural gas liquefaction plant. At present, the small-scale natural gas liquefaction plant equipment produced by Xuebei Company is completely domestically produced, and its energy consumption indicators and investment costs are superior to foreign ones.

This kind of small natural gas liquefaction plant has a low energy consumption ratio index that is comparable to large and medium-sized liquefaction plants; because the complete set of equipment is completely localized and mass-produced, the equipment cost is quite low; due to the adoption of many new technologies , new processes and new materials make this small liquefaction plant have a very high level of safety, reliability and automation. Especially in terms of modularization, skid-mounted and vehicle-mounted, it is difficult to compare with the previous traditional natural gas liquefaction technology.

No matter which gas source is used, whether coal bed methane, oil field gas, biogas or pipeline gas, the main component is methane, but the other accompanying impurities are slightly different. The liquefaction temperature of methane under normal pressure is below zero degrees Celsius. At about 160 degrees, the volume of liquefied methane is reduced by 625 times. It can be canned and stored in normal pressure liquid cylinders or storage tanks with vacuum insulation and cold insulation. These containers containing liquid methane have very good insulation capabilities, even during transportation There is only a trace amount of volatilization along the way. Because it is a normal-pressure container, it does not require a thick-walled container like CNG cylinders, so LNG cylinders are very light. Various impurities contained in the raw gas before liquefaction, including particulate dust, water, carbon dioxide, sulfide, etc., must be completely removed. The liquefied natural gas is highly pure methane, so the use of LNG natural gas in automobile engines requires It has a much longer life than CNG natural gas that has not been liquefied, and the environmental indicators of vehicle exhaust emissions using LNG are better than any fuel except hydrogen. Liquid methane is colorless and odorless, does not support combustion and will not explode. A lit cigarette will be extinguished when thrown into a beaker containing LNG. LNG is a very safe fuel. Since methane is less dense than air at normal temperatures and pressures, LNG spilled on the ground will evaporate quickly. Therefore, LNG is safer than gasoline and diesel. The world's LNG industry has developed almost without accidents for sixty years.

Xuebei Company has ISO9000 certification and various qualifications necessary for the production of liquefied natural gas equipment. The design of the WSCE-MiniLNG liquefaction plant fully complies with international and domestic safety standards.

Harbin University of Technology Xuebei Cryogenic Equipment Co., Ltd. has applied for the registered trademark and patent of WSCE-MiniLNG.

WSCE-MiniLNG liquefaction plant standard series is divided into three categories: natural gas liquefaction plant equipment, vehicle gas filling station equipment and residential gas supply station equipment according to user characteristics. The corresponding upstream and downstream supporting equipment can be added or subtracted in design according to the specific requirements of the owner.
