Patented liquid sampling system

Liquid sampling robot equipped with a compact manifold aiming at depressurizing the effluent immediately after each reactor in separate reactor lines to atmospheric pressure. Reactor effluent is depressurized by a miniaturized (low volume) parallel dome regulator, allowing a stable control of gas or gas/liquid product streams. This eliminates the use of valves at high pressure (such as multi-position valves), which are prone to leakage.

Gas liquid separation can be performed directly by collecting liquid phase products in sample vials, while directing gas phase products towards online gas analyzer. This approach minimizes required flush times in the downstream section of the reactor making high pressure gas-liquid separators, level sensors, and drain valves obsolete.

    Microfluidics modular gas distribution

    Unrivalled accuracy in gas distribution with patented glass-chips for 4 and 16 reactors, with a guaranteed flow distribution of 0.5% RSD. Quick exchange of glass-chips for different operating conditions. Flexibility to cover a wide range of applications.

    TinyPressure glass-chip holder with integrated pressure measurement

    Compact modular design for gas and liquid distribution. No high-temperature pressure sensors required. Quick exchange of the microfluidic glass-chips, without the need for time-consuming leak testing.

    Tube-in-tube reactor technology with effluent dilution

    Unique tube-in-tube design with easy and rapid exchange of the reactor tubes (within minutes!). No need for any connections. Use of inert diluent gas (outside of reactor) to maintain the pressure prevents dead volumes and back flow. Possibility to use quartz reactors at high pressure applications.

    Automated liquid sampling system

    Programmable, fully automated liquid product sampling robot for 24/7 hands-off operation. Robot equipped with a compact manifold aiming at depressurizing the effluent immediately after each reactor to atmospheric pressure. Eliminates the use of high pressure valves.

    Reactor Pressure Control (RPC)

    The most accurate and stable pressure regulator for a 16-parallel reactors with just ±0.1bar RSD. The RPC uses microfluidics technology to regulate the pressure of each reactor, maintaining equal distribution of the inlet flow over the 16 reactors.

    Auto-calibrating liquid feed distribution, measurement, and control

    Distribution of difficult feedstocks e.g., VGO, HVGO, DAO. Liquid distribution 0.2% RSD, making it the most accurate liquid distribution device on the market. Option to selectively isolate each reactor.

    Single-Pellet-String-Reactors (SPSR)

    No dead-zones, no bed packing & distribution effects. The catalyst packing is straightforward and does not require special procedures. A single string of catalyst particles is loaded in the reactors avoiding maldistribution, eliminating channeling and incomplete wetting.

    EasyLoad®

    Unique reactor closing system with no connections. Rapid reactor replacement minimizing delays, improving uptime and reliability. Stable evaporation by liquid injection into reactor.
