据世界天然气网站2月22日消息 俄罗斯镍钯矿业公司Nornickel计划开发一个项目，在该公司原镍厂的场地上生产液化天然气，以大幅减少碳排放。
该项目是该公司实施的环境计划的一部分。公司计划将重型采矿设备转为柴油和液化天然气等双燃料消耗。目前，该公司正在为液化天然气工厂开发通用技术解决方案。
据估计，这项新技术将大大有助于减少一氧化碳和二氧化碳、氮氧化物、二氧化硫等排放。
此外，为使用液化天然气的双燃料作业重新装备自卸车的试点项目也在进行中。
试验定于2021年下半年进行。公司选择了四辆BelAZ矿业自卸卡车，其发动机将升级为柴油和液化天然气模式。
这些试验旨在确定是否有可能用液化天然气替代40%的柴油。试验结果出来后，将决定是否重新装备采石场开发中使用的整个自卸卡车车队（约30辆）。重新装备用于其他大型项目的矿用自卸汽车的决定也将被修改。
液化天然气工厂的建设预计将在2022年1月至2023年3月之间进行。

Nornickel to build an LNG plant in the Arctic
Russian nickel and palladium mining company Nornickel plans to develop a project to produce LNG on the site of the company’s former Nickel plant to significantly cut carbon emissions.
The project is a part of an environmental program implemented by the company. The company plans to transfer heavy mining equipment to dual-fuel consumption, such as diesel and LNG. It is currently developing general technical solutions for the LNG plant.
It is estimated the new technology will significantly help to reduce emissions of carbon monoxide and dioxide, nitrogen oxides, sulphur oxide and dioxide, as well as carbon.
A pilot project to re-equip dump trucks for dual-fuel operation using LNG is also underway.
Trials are scheduled for the second half of 2021. They have chosen four BelAZ mining dump trucks and their engines will be upgraded to operate in diesel and LNG modes.
The trials are to identify whether it is possible to replace 40 per cent of diesel fuel with LNG. After the results of the trial, it will be decided whether to re-equip the entire fleet of dump trucks used in the development of the quarry (approximately 30 vehicles). The decision to re-equip mining dump trucks used for other large-scale projects will also be revised.
The construction of the LNG plant is expected to take place between January 2022 and March 2023.
