ENVIMAC Engineering GmbH products

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.
