Why choose us?

Diverse Tower and Internals Supply

We provide a wide range of towers and internals in materials like special alloys, ceramics, graphite, plastic, and stainless steel. Liquid distributors (orifice, trough, ladder, spray nozzle types) and gas distributor spargers are designed for uniform distribution, considering scaling/foaming factors. Packing supports, bed limiters, and mist eliminators (mesh/chevron types) are offered to enhance purity and prevent equipment damage.

High-Quality Industrial Equipment Provision

Specializing in chemical industry equipment, we offer top-grade materials resistant to corrosive/abrasive chemicals (solvents, acids, oils, etc.). Product lines include diverse pumps (barrel, pneumatic diaphragm, centrifugal) and customized skid-mounted systems for single-point connection. All equipment meets API standards, with pumps complying with ANSI for guaranteed reliability.

Innovative Energy-Saving & Intelligent Solutions

We design energy-efficient chemical plants, optimizing processes with high-efficiency heat exchangers and energy-saving pumps/fans. Intelligent solutions integrate big data, AI, and IoT for real-time process control, equipment fault prediction, and remote monitoring, enabling clients to achieve dual economic and environmental benefits.

The company’s chemical process design services are rooted in technical excellence and project execution expertise. Starting with process synthesis, multiple route options are evaluated using criteria like atom economy, E-factor (environmental factor), and process complexity. For example, a pharmaceutical API production process was designed using a continuous flow reactor instead of batch, improving yield from 68% to 89% and reducing solvent usage by 70%. Detailed design includes equipment specification (reactors: jacketed with heating/cooling media, heat exchangers: U-tube with removable bundle), piping and instrumentation diagrams (P&IDs), and control philosophy development. Design reviews are conducted at key milestones (conceptual, preliminary, detailed) to ensure alignment with client requirements, including HSE (health, safety, environment) considerations. The company also provides process design packages (PDPs) suitable for construction, including material take-offs, equipment datasheets, and plot plans.

Customer Reviews

Robert Parker

Their process design team delivered a highly efficient plan for our new chemical product, optimizing reaction conditions and equipment layout. Using advanced simulation software, they ensured the design was both economically viable and environmentally sustainable. The attention to detail in safety and regulatory compliance is commendable.

Sarah Davis

When designing our new catalyst production line, their team used cutting-edge simulation tools to model different reaction scenarios. This allowed us to select the optimal process parameters before construction, saving time and costs. Their ability to translate complex chemical processes into practical designs is impressive.
