For ex-The SSLNG unit at Vijaipur.<\/p>\n<h2><strong>How does the SSLNG unit at Vijaipur work?<\/strong><\/h2>\n<p>1) There are treatment skids \u2014 zeolite pretreatment skids (ZPTS) \u2014 and liquefaction skids. They are known as cryo boxes which convert natural gas to LNG.<\/p>\n<p>2) Natural gas is processed in the ZPTS at a pressure of approximately 15 bar to remove non-desirable components such as nitrogen, water, sulphur, and carbon dioxide.<br \/>\nIt is then fed to the cryo box, where it is compressed in a four-stage compressor to a pressure of around 260 bar.<\/p>\n<p>3) The gas is cooled by a propane-based external refrigeration system to minus 60-70 degree Celsius. After that, the gas is subjected to expansion so that the temperature falls below minus 140 degrees Celsius and it can liquefy.<\/p>\n<p>4) The LNG is then dispatched by cryogenic tankers to nearby areas for use in city gas distribution networks as CNG and piped gas.<\/p>\n<p>5) The SSLNG unit is controlled by an automated, web-based Supervisory Control and Data Acquisition (SCADA) system, typically used to monitor large industrial devices and processes.<\/p>\n<p>Read more- <a href=\"https:\/\/forumias.com\/blog\/upsc-current-affairs-news\/yojana-november-2023-energy-transition-in-india\/#:~:text=What%20steps%20have%20been%20taken%20by%20India%20towards%20Energy%20Transition%3F,-The%20Government%20of&amp;text=Energy%20Conservation%20Amendment%20Act%2C%202022,energy%20and%20feedstock%20in%20industries.\">Energy Transition In India<\/a><\/p>\n<h2><strong>What is the significance of small-scale liquefied natural gas (SSLNG) unit?<\/strong><\/h2>\n<p>1) <strong>Transition to green energy<\/strong>-The government aims to increase the share of natural gas in its primary energy mix to 15% by 2030 from 6% at present. This is because natural gas is far less polluting than conventional hydrocarbons like coal and oil. It is seen as a key transition fuel in India\u2019s journey towards green energy and future fuels.<\/p>\n<p>2) <strong>Decarbonization of transportation sector<\/strong>-It is cleaner fuel with reduced emission of carbon dioxide and negligible amounts of particulate matter, nitrogen oxide, and Sulphur dioxide as compared to diesel.<\/p>\n<p>3) <strong>Overcome transportation challenge of Natural Gas<\/strong>-There are many places that are not connected by the country\u2019s natural gas pipeline grid. This hinders the use of LNG directly as fuel for long-haul trucks and inter-city buses. This challenge can be overcome by small-scale liquefied natural gas unit.<\/p>\n<p>4) <strong>Save forex reserve<\/strong>-It is usually cheaper than crude oil, from which diesel is derived. Thus, replacing a major chunk of India\u2019s diesel consumption by LNG could lead to substantial foreign exchange savings.<\/p>\n<h2><strong>What are the challenges in its wider adoption?<\/strong><\/h2>\n<p>1) <strong>Paucity of LNG-powered vehicles<\/strong>-There is shortage of LNG-powered vehicles in India.<\/p>\n<p>2) <strong>High cost<\/strong>-The LNG-powered vehicles have higher initial cost as compared to diesel run vehicles.<\/p>\n<p>3)<strong> Financing ecosystem<\/strong>&#8211; India does not have a robust LNG vehicle financing ecosystem.<\/p>\n<p>4) <strong>Retail network<\/strong>-India does not have LNG retail network.<\/p>\n<h2><strong>What steps have been taken to overcome this challenge?<\/strong><\/h2>\n<p>1) Companies such as GAIL and Petronet are working to build a viable ecosystem for transporters to move from diesel vehicles to LNG.<\/p>\n<p>2) Petronet has collaborated with commercial vehicle manufacturers and other public sector oil &amp; gas companies for trials and pilot projects for LNG-fuelled trucks and buses.<\/p>\n<p>3) Petronet has established a few LNG dispensing stations along highways.Similarly,Indian Oil Corporation is also planning to build LNG dispensing stations along major highways.<\/p>\n<p><strong>Question for practice<\/strong><\/p>\n<p>What is SSLNG?
