Lo Brothers Engineering Co.,Ltd

Water remediation requirements can include clarification and/or filtration of suspended solids, pH neutralization of acidic or alkali waste streams, demineralization, and removal of hazardous organic contamination.

The requirements range from disposal allowance to reuse as plant process water to recovery of valuable products in the contaminated stream.

We offer process engineering, system design and supply, and plant integration of several technologies to meet these needs.

Methanol Purification System & Methanol Recovery System

Methanol purification system is a unique, patented process by A.H Lundberg that produces streams of high purity methanol, de-hydrated stripper off-gas (SOG), and high quality stripped water from kraft pulp mill foul process condensates or refinery sour water streams.

Methanol Recovery System provides energy savings and environmental benefits to process industries disposing of effluent streams containing methanol. Recovery System provides energy savings and environmental benefits to process industries disposing of effluent streams containing methanol.

As separate products, both the recovered methanol and the stripped condensate contribute operational and economic value to the plant.

Crystallizers

Crystallizers are used to produce a solid crystals product, typically a salt, by evaporating a solvent, typically water, from a supersaturated mixed suspension of crystals and liquor.

Crystallizer technology is a natural development from half century of experience by Lundberg in multiple effect evaporators and high solids concentrators. Systems may consist of single or multiple effects.

Steam Stripping

An effective method of treating process foul condensates (sour water) contaminated with hazardous hydrocarbons, sulfides, ammonia, methanol, and TRS is the distillation of the waste water stream through steam stripping.

Every stripping system contains the same basic components including a feed tank, filter, condensate pre-heater, stripper column with rectification section and a reflux condenser.

Evaporation

Purification of waste water streams through evaporation can provide industrial facilities the opportunity to recapture and reuse nearly all liquid waste streams.

Full demineralization of the waste water and zero liquid discharge is available through the additional step of evaporative crystallization of the dissolved contamination, providing the plant with the opportunity to dispose of solid waste salts only.
