Our Services

Why Choose Our Services?

RFP Facilitation

We can manage your H2S removal RFP from start to finish and ensure you select the most efficient solution, in terms of service and treatment cost ($/BOE or $/kg H2S removed). We know what questions to ask to ensure the vendor's solution is targeted to the client's needs.

SRU Design

We utilize in-house developed software to model and design the ideal Sulfur removal system that fits your needs. We have extensive experience in most application methods and equipment packages, including co-current and counter current dynamic contactors, static systems, Fixed bed adsorbers, and direct injection systems.

Scrubber Design

Apart from our standard portfolio of scrubbers, we can also assist you with custom designs for applications that are out of the ordinary. Our liquid scrubber systems are the most efficient on the market, maximizing scavenger (absorbent) usage and thus lowering annual treatment costs.

System Optimization

We can assist clients with analyzing and troubleshooting existing H2S removal systems with the goal of increasing scavenging efficiency and reducing operational downtime. Our modelling software can identify critical factors in existing Bubble Columns that are causing solids formation or poor efficiencies.

H2S Management

We can manage all aspects of your H2S removal needs, from an initial field survey to designing and implementing a suitable program. A hand-off approach is also possible in which FirstKlaz technologies would monitor the system, manage chemical consumption and logistics. A monthly report will then be provided which covers chemical expenditure and usage.

Water Management

We can design programs for H2S removal for both wastewater and freshwater systems. Programs are designed to meet all environmental regulations. Scrubbers can also be designed to be used with our extensive portfolio of water treatment chemistries.
