Continuous Pressure and Vacuum Filtration and Washing of Organic Cellulose and Biomass Products
Author: BHS Filtration
Posted: 09/11/2009
Organic cellulose and biomass filtration, washing and drying is very unpredictable and even minor differences in feedstock,washing or cake moisture requirements can require a different process solution. Both vacuum and pressure operations can provide equivalvent process results. On-site testing is required to determine the optimum filter selection.

Removing Liquid From Gas
Author: Sulzer Chemtech USA
Posted: 09/17/2007
Liquid entrainment in a gas stream can be a disturbance in many industrial processes. In natural-gas processing, higher-order hydrocarbons, water or impurities have to be separated from the main methane stream. Upstream of gas compressors, droplets that can damage the impellers, have to be removed. With the recently acquired Knitmesh technology and the strategic alliance with Shell Global Solutions, Sulzer Chemtech can supply a broad portfolio of advanced, tailor-made systems for gas/liquid separation to customers in all industries.

Rectifier design for fuel ethanol plants reduces energy
Author: Sulzer Chemtech USA
Posted: 04/10/2007
Plants have traditionally used trays in the distillation columns to produce fuels grade ethanol. Trays of various configurations have been adequate in this service and their technology is well founded. The ever-present desire to reduce the energy needed to produce a gallon of ethanol has opened the doors to structured packings being used in the rectification sections of ethanol distillation columns.
