Solvent dewaxing

Although the name “hydrotreating” is similar to light stream hydrotreating, the hardware and yields in residue hydrotreating are different. Residues have a much higher carbon to hydrogen ratio and therefore require a larger volume of hydrogen in the reactor. In addition, residue hydrotreaters are set at higher pressures to minimize coke formation. So a residue hydrotreater is similar to a hydrocracker, as both use hydrogen and catalyst to enrich the hydrogen content of the olefin feedstock. However, the degree of saturation is not as great as in hydrocracking.

Hydrotreating processes differ depending on the feedstock and catalysts. Lube oil hydrotreating uses catalytic treatment of the oil with hydrogen to improve product quality. The objectives in mild lube hydrotreating include saturation of olefins and improvements in color, odor, and acid nature of the oil. Mild lube hydrotreating may also be used following solvent processing. Severe lube hydrotreating, at higher temperatures and higher hydrogen pressures, can saturate aromatic rings and remove sulfur and nitrogen.

DMA 35 Ex Petrol

The DMA 35 portable density meter measures the density, SG and °API of samples on-site within seconds. The intrinsically safe instrument (ATEX-marking II 2 G Ex ib IIC T4) has a special housing, resistant to petroleum samples. It is therefore perfectly suitable for measuring petroleum samples in hazardous areas. The integrated RFID interface enables quick sample identification (e.g. tank number) before measurement. Measured results can be stored and printed or exported to a PC wirelessly via IrDA later on. The instrument fully complies with the ASTM D7777 standard.
