Integrated wastewater treatment and reuse. Wastewater from the tall oil fractionation plant's processes consists mainly of polluted condensates from the vacuum system. ... In order to reduce the water load, turpentine-containing process wastewaters from the plant are fed into the Botnia pulp mill's wastewater stripper and from there into the pulp mill's own water cycle. This procedure lowers raw water consumption by the local forest industry and the tall oil fractionation plant.

CONT

Fiber optic converter boxes were also installed, along with Foxboro DCS Consoles and Triconex shutdown equipment. Two stripping columns, a drum and seven pumps were added to increase capacity of the wastewater stripper, which strips benzene, MNB and aniline from wastewater.

CONT

T019 (Barex Recycled Monomer Tanks). Barex Plant Recovered Monomer Tanks (T-8, T-18, T-19) and associated equipment. These are holding tanks for monomers recovered by the wastewater stripper columns before recycle back to Barex reactors.
