Linde Engineering: Contract signed for 8 shell-and-tube heat exchangers for Inner Mongolia HuiNeng’s project Author/Source: Date: 2018-12-20 Clicks: 2 According to a report dated December 18, Linde Engineering (Dalian) Co., Ltd. and Inner Mongolia HuiNeng Coal Chemical Co., Ltd. recently signed a contract in Ordos for the supply of 8 low-temperature methanol wash shell-and-tube heat exchangers as part of the second phase of a project aimed at producing 1.5 billion cubic meters of coal-based natural gas per year. This heat exchanger will be used in the low-temperature methanol washing unit, with a delivery period of 16 months. It is understood that the contract for the coil-type heat exchanger is the third contract following the agreement signed in October this year between Linde Engineering and HuiNeng Coal Chemicals for a 2×100,500 Nm3/h (O2) air separation unit along with the associated LNG liquefaction facility; it represents yet another example of Linde Engineering’s integrated technologies and services. Linde’s coil heat exchangers feature a wide range of operating temperatures and pressures, the ability to handle multiple fluids in a single exchanger, a compact footprint, high heat exchange efficiency, strong pressure resistance, and a robust design that enables them to withstand thermal stresses resulting from repeated start-up and shutdown cycles as well as large temperature differences. Linde Engineering states that it has delivered over 1,000 coil heat exchangers to date, making it a global leader in this technology sector. It is reported that the coal-to-natural gas project of Inner Mongolia HuiNeng Coal and Electricity Group Company is located in the Shengyuan Coal Chemical Industry Base in Yijinhuoluo Banner, Ordos City. This project uses coal as raw material to produce synthetic natural gas and liquefied natural gas, and it is the first demonstration project of coal-to-natural gas in China to be invested and built by a private enterprise. The construction of this project is carried out in two phases: Phase 1 required an investment of around 7 billion yuan; it began operations in October 2014, with all 400 million cubic meters of natural gas being liquefied ； The natural gas liquefaction project (LNG) as part of the second phase is a load-driven natural gas liquefaction plant. Construction is scheduled to begin in the second half of 2018, with an estimated investment of 12 billion yuan. The construction work will include natural gas purification, liquefaction, storage of liquefied natural gas, transportation, as well as related supporting facilities. The project will add an output capacity of 1.6 billion cubic meters of coal-based natural gas, all of which will be liquefied; it will also be able to process 2.7 million Nm3 of natural gas per day. Completion and operation are expected by July 2021.
