魁北克的钻井废弃物

案例研究

挑战

Driller for major gas distributor requires cost effective solution for disposing of drilling waste in Quebec near Pierre Elliott Trudeau International Airport. The drill site was in an urban setting with high traffic volume. Drill spoils waste was too liquid and would not be accepted by local disposal site. The Ministry of Sustainable Development, Environment and the Fight against Climate Change requires treatment of liquid drilling waste in Quebec as liquid industrial waste. With only small sumps on site and nearly 1,000m3 of waste, a quick and cost effective disposal option was needed.

解决方案

After assessing several solutions, solidification on site using MetaFLO’s MF006 mechanical solidification reagent was chosen. The plan was to solidify the drilling fluids on site to achieve the required solids criteria. After solidification, our client would be able to ship the waste using dump trucks for disposal at the nearby solids disposal facility. Shipping and disposal of the liquid drill waste would have been more costly, meant greater risk and had a greater environmental footprint.

结果

The solidification process was a success. All of the mud was solidified quickly and accepted by the solids waste receiver. Cost was reduced due to the lower cost of dump trucks and solids disposal. Additionally, solids allow for larger volume per truck reducing the project’s carbon footprint and safety risks.

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。
