DELKOR India thickener for Arab Potash: process design notes for HLP engineers

30 Second Briefing
DELKOR India has secured an EPC contract from Arab Potash Company to supply a 50 m diameter DELKOR Thickener for the Hot Leach Potash (HLP) circuit in the firm’s latest capacity expansion project. The large-diameter unit is designed for high-throughput liquid/solid separation in hot brine conditions, a critical bottleneck in potash crystallisation and recovery. For process and tailings engineers, the installation signals further scaling of HLP operations at Arab Potash’s Jordan facilities, with implications for water balance, underflow rheology and downstream evaporation capacity.
Technical Brief
- Package is described as a “major” EPC contract, implying multi‑disciplinary engineering and construction involvement.
- Robust liquid/solid separation design is tailored to potash brine chemistry and elevated operating temperatures.
- Thickener selection is intended to support higher plant availability and reduced maintenance in corrosive brine service.
- Similar large‑diameter thickeners are increasingly specified in potash expansions to debottleneck thermal and evaporation circuits.
Our Take
A 50 m-diameter thickener for a hot leach potash application puts Arab Potash’s expansion in the same ‘large-scale brine handling’ bracket as the big greenfield builds like BHP’s Jansen project, which our coverage notes has seen its Stage 1 capex estimate rise to US$8.4 billion.
Across the several potash-tagged pieces in our database, most recent investment has clustered in Saskatchewan and the US, so a sizeable process-equipment award tied to Arab Potash signals that brownfield debottlenecking in established Middle Eastern brine operations is still attracting meaningful capex alongside the Canadian mega-projects.
The focus on high-capacity mechanical and process units for potash – from Sandvik’s cutting hubs in Saskatoon to this 50 m DELKOR thickener – suggests operators expect sustained throughput growth and are standardising on fewer, larger units, which has implications for tailings and brine pond design loads at expansion projects.
