Drill Mud Sump in Fort McMurray, Alberta

案例研究

挑战

Large volume of oil and gas exploration drilling fluid stored in drill mud sump to be solidified in severe cold in Fort McMurray, AB in January. Long distance to liquids disposal site made liquid transport and disposal costs extremely high. After treatment, the solidified waste drill fluids were transported to a solids disposal site saving approximately 8 hours per load.

解决方案

Large volumes and other logistical issues necessitated MetaFLO’s reagents to be mechanically mixed with the waste drill mud. Mixing was completed by an excavator in the storage sump. MetaFLO’s reagents perform well in extreme cold and achieved the required paint filter solids criteria on this project.

结果

Competing reagents were treated concurrently on another site for comparison by the owner. While the competing process was rejected at the landfill, MetaFLO’s treated solids met the same landfill’s requirements and were accepted.

挑战

淡水河谷公司在加拿大安大略省北部拥有并经营着一个采矿场。通过采矿和精炼活动,他们产生了一种污泥废物副产品。客户需要一个高效的挖掘和运输解决方案,将这些污泥运到场外的垃圾填埋场。

日期

2018 年 9 月底 - 2018 年 10 月中旬

解决方案

在竞标过程中,MetaFLO 参与提供了最佳的混合料和加料率,以达到污泥挖掘和运输所需的固体标准。MetaFLO 利用分析数据估算出的剂量率为 1.1%(按重量计)(基于高含水量)。建议使用大型搅拌桶,以增加表面接触,提高桶搅拌过程的效率。目前尚未获得样本。

结果

Tervita 公司利用 MetaFLO 试剂固化了约 4,000 立方米的污泥。现场有两个 35 立方米的垃圾箱,装载着 "较重 "和 "较轻 "的污泥。最初估计的用量是准确的,因为实际处理平均每立方米污泥大约需要 30 磅 MetaFLO MF006 试剂。所有材料都被安全地运往淡水河谷的场外垃圾填埋场。工作按时完成。
