TREATMENT OF AMMONIA PLANT PROCESS
The report gives results of an examination of contaminant content and selected treatment techniques for process condensate from seven different ammonia plants. Field tests were performed and data collected on an in-plant steam stripping column with vapor injection into the reformer furnace stack. Bench scale steam stripping was studied on several different plant process condensates for

Ammonia Plant Confidential 4 Process Description Plant for Ammonia production started-up in 1984 and may use as raw material any hydrocarbon liquid or gaseous. However, this plant is mostly oriented for use of heavier fractions from oil distillation, namely vacuum residues or even asphalt residues. The plant capacity is 900 Ton/day, 80% of this production was used for 3 Fertilizers plants and
Fertilizer Manufacturing Effluent Guidelines | Effluent
EPA initially promulgated the Fertilizer Manufacturing Effluent Guidelines and Standards (40 CFR Part 418) in 1974 and 1975, and amended the regulation between 1975 and 1987.The regulation covers direct direct dischargerA point source that discharges pollutants to waters of the United States, such as streams, lakes, or oceans. and indirect indirect dischargerA facility that discharges
Tackling ammonia at the wastewater treatment plant
Although treated effluent contributes a much smaller source of ammonia, reducing the quantity of wastewater treatment discharge can help significantly reduce the total ammonia and nitrogen amounts below critical load thresholds.

EFFLUENT TREATMENT PLANT Angelfire
EFFLUENT TREATMENT PLANT . SOURCES OF EFFLUENTS FOR HYDROLYSER. STRIPPER Effluents for hydrolyser stripper are coming from the ammonia and urea plants. The effluents contain Ammonia, carbon dioxide and very few inerts with 0.4% urea. AMMONIA PLANT EFFLUENTS Ammonia plant effluents are mainly from, 1. Ammonia vent stack separator drain. 2. III – boiler

Wastewater treatment Clustered wastewater treatment
If direct reuse as a potable supply is intended, tertiary treatment with multiple barriers against contaminants is required. This may include secondary treatment followed by granular media filtration, ultraviolet radiation, granular activated carbon adsorption, reverse osmosis, air
Condensate an overview | ScienceDirect Topics
When the gas is cooled, excess steam condenses out and forms process condensate. The process condensate thus generated contains ammonia, methanol and some organics. In newer plants, built–in systems are provided for removal of the major quantity of ammonia by stripping.
Sewage treatment Wikipedia
Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater.Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment.A by-product of sewage treatment is a semi-solid waste or
TREATMENT OF HIGH-STRENGTH AMMONIA LIQUORS
The plant replaced an existing SBR liquor treatment plant, and treats liquors arising from pre-digestion thickening, post-digestion dewatering, and condensate from a sludge dryer. The plant comprises a balance tank with mixing system, hot and cold liquor blending system and the Amtreat plant.
DAIRY EFFLUENT | Dairy Processing Handbook
Present-day effluent treatment processes concentrate on the reduction of nitrogen, phosphorus salts and heavy metals. Nitrogen and phosphorus compounds are important, as they are nutrients for organisms, e.g. algae, in recipients. As a result of the growth of algae, secondary processes can proceed in the recipient, forming further organic substances which, when they decompose, can result

To achieve zero effluent from the plant, the following inbuilt facilities have been provided: Process condensate stripper to strip off dissolved gases from process condensate with steam. After stripping the condensate is sent to DM plant for further treatment to convert it to the Demineralized Water . Turbine condensate is sent to DM plant for polishing and used as boiler feed water . Boiler

How to Treat Sewage from Fertilizer Industry? | Waste
In a typical nitrogenous fertilizer unit manufacturing urea the amount of sodium hydroxide in the water treatment plant effluent is 11.6 kg/tonne of urea manufactured. The total sulphate ion quantity is 18.2 kg/tonne of urea manufactured. Besides these, when a process condensate is treated for use as boiler feed water, ammonia finds its way into the water treatment effluent. (iii) Boiler Blow
Industrial wastewater treatment for fertilizer industry- A
For example, wastewater is generated from ammonia plant contains ammonia, methanol, and trace metals. Treatment involves condensate steam strippers to remove ammonia and methanol followed by ion exchange. Methanol production unit also generates wastewaters containing alcohol and is a major pollution problem.
