ENVIMAC Engineering GmbH products

Column design and fabrication: ENVIMAC offers design, fabrication and optimization of columns for fluid separation processes such as distillation, absorption, stripping and liquid/liquid extraction and column internals. Columns and vessel are designed and fabricated according to PED or ASME code and fulfill highest demands regarding quality and performance. State-of the art column internals and individual solutions designed to solve the customer’s specific problems assure satisfying and long lasting solutions.

The liquid distributor is an essential part of every separation tower or column. The quality of the liquid distribution has large influence on column performance. ENVIMAC Engineering GmbH designs, constructs and delivers modern column internals like liquid and gas distributors with performance features such as high-efficiency distribution, high resistance to soiling and low pressure drop. We provide distributors made from various materials, like high performance plastics and stainless steel and different designs, always designed and customized in regard of the process specifications and the column packing type. Our portfolio covers:

A packing, e.g. random packings, need a support to be installed inside the column. The support grid should be strong enough to withstand the weight of the packing and the hold-up, but also provide enough open area for the gas to pass without creating large pressure drop.

Collection trays are used in tall columns, when the packed height is very large. In this case, the liquid is collected and re-distributed in order to guarantee a high separation efficiency throughout the packed bed. Different types of collection trays, re-distributors and combi-trays, which combine both the collection and the liquid distribution in one device, are offered by ENVIMAC.

Down hold grids are used as a bed limiter in packed columns. The keep the random packed bed in its place to avoid packings to be discharged from the column, e.g. at high gas or vapour loads or when high pressure is applied. We offer down hold grids or bed limiters with low pressure drop in different shapes and made from various materials such as PE, PP, PVDF, SS304, SS316 and many more.

McPac - ENVIMAC’s high-performance, 4th generation random metal packing Mc-Pac has been designed as a special random packing for all kinds of rectification, absorption, desorption and extraction processes. It features lower pressure drop and higher separation capacity compared to standard packings, is available in 3 sizes and especially insensitive to fouling and thus can be applied in all kinds of thermal separation and direct heat exchange processes. Materials: stainless steel 304, 316Ti and other on demand, Available sizes: 1, 2, 3.

ENVIPAC: Only ENVIMAC Engineering GmbH provides the original ENVIPAC high-performance tower packing. ENVIPAC is a spherical lattice-type packing that been specifically developed for gas treatment. It can also be used in processes with very low liquid loads.

SR-PAC und R-PAC – In comparison with classical packings the R-Pac and SR-Pac packing, made from stoneware (ceramic) or porcelain, have the following advantages: lower pressure drop, greater operating range, better efficiency, high mechanical strength.

Vane type separators are used to separate liquid droplets or dust from gas or vapour streams. They can be used at high gas or vapour velocities and allow high separation efficiency at low pressure drops. Vane type mist eliminators can be installed inside columns, evaporators and other vessels, or in a separate casing inside piping. The flow direction may be horizontal or vertical.

Radial spin mist eliminators type HRT are used to separate large quantities of liquid and condensate or dust from gas streams. They can be installed in vertical or horizontal position, e.g. in stacks, chimneys or pipelines.  Various materials and sizes are provided to meet the customer’s requirements. Available materials are polypropylene (PP), polyethylene (PE), PVDF, GRP, steel and stainless steel e.g. SS304, SS316Ti, duplex-steel and others on demand.
