PUREVAP™ TECHNOLOGY
ONE-STEP LOW-EMISSION TRANSFORMATION OF QUARTZ TO HIGH-PURITY SILICON
PUREVAP™ TECHNOLOGY
ONE-STEP LOW-EMISSION TRANSFORMATION OF QUARTZ TO HIGH-PURITY SILICON
The PUREVAP™ is a one-step proprietary process that uses a plasma arc within a vacuum furnace to transform quartz into high-purity silicon. Through the PUREVAP, HPQ will supply silicon to a range of diverse manufacturing applications critical to reaching net-zero emissions.
The PUREVAP™ process reduces quartz with carbon using a plasma-submerged arc. Under vacuum — and at very low operating pressure — impurities are removed from the silicon until its left in its purest form.
With a patented, scalable, and ESG-compliant high-purity silicon metal production process, HPQ is positioned to grow as needed to fulfil the rising demand for silicon metal. The company’s strategic location in Montreal, North America, is yet another advantage, as HPQ benefits from close proximity to end-users, decreasing transportation costs and eliminating international supply chain disruptions.
OUR PUREVAP™ TECHNOLOGY PROJECTS
PRIORITISING ESG
To better serve our investors, portfolio firms, and the communities we work in, HPQ is committed to integrating ESG elements into our corporate mission, vision, and performance as extensively as possible. For us, it’s about driving real change.
OUR APPROACH
Efficiency is at the heart of everything HPQ does. Relative to conventional high-purity silicon manufacturing methods, PUREVAP reduces overall costs, greenhouse gas emissions, and feedstock materials to drive a decisive cost advantage that can be passed along the value chain.
THE PUREVAP™
ADVANTAGE
The PUREVAP™ technologies are designed with superior operational efficiency — vastly outperforming conventional manufacturing techniques.
The PUREVAP™ Quartz Reduction Reactor uses 25% less material feedstock per Mt of high-purity (>99.5%) silicon metal for a 20% cost advantage.
25%
PUREVAP™ Nano Silicon Reactor (NSiR) produces nano-silicon materials from < 0.20 µm up to 5 µm to supply a range of critical battery applications.
5µm
PUREVAP™ Fumed Silica Reactor (FSR) reduces the energy footprint of fumed silica production by 86% to capitalize on growing ESG flows.
