Colombia stands at an industrial turning point. With significant sea salt operations along the northern Caribbean coastline—most notably in Manaure, Galerazamba, and Santa Marta—millions of cubic meters of mother liquor (bittern brine, or agua madre) are historically discharged as waste back into the sea. These brines contain rich, unexploited concentrations of magnesium ions ($Mg^{2+}$) and chloride complexes that present exceptional valorization opportunities when processed through custom-engineered evaporation and crystallizing plants.
Concurrently, Colombia’s heavy industrial sectors are facing severe cost spikes from imported chemical stabilizers. The domestic demand for high-grade hexahydrate magnesium chloride ($MgCl_2\cdot 6H_2O$) and brine solutions is surging across three primary economic arteries:
Establishing localized, in-country processing infrastructure allows Colombian chemical producers and mining consortia to replace costly containerized imports from China, the Dead Sea, and North America with locally manufactured, high-purity flakes and concentrated liquors.
Transitioning solar salt harvesting operations into integrated multi-chemical extraction platforms. Extracting $NaCl$, Bromine ($Br_2$), and Magnesium Chloride ($MgCl_2$) triples the revenue per hectare of evaporative pan.
Shielding domestic industrial buyers from Colombian Peso (COP) vs. US Dollar fluctuations by localizing the supply of industrial-grade chemical flakes.
Direct transit corridors from ports like Cartagena, Barranquilla, and Santa Marta inland via the Magdalena River freight systems reduce transport overhead for bulk raw chemical goods.
Standard off-the-shelf equipment designed for temperate dry salt flats inevitably fails in Colombia's micro-climates. Here is how customized turnkey engineering bridges the operational gap.
| Engineering Dimension | Standard Global Template (Generic Importers) | Ruitu Custom Engineered Plant for Colombia |
|---|---|---|
| Raw Feed Adaptability | Requires pre-refined, constant feedstock with tightly controlled sulfate-to-magnesium ratios; highly sensitive to variations. | Custom desulfurization reaction tanks with precision chemical dosing; seamlessly treats high-sulfate Caribbean marine bitterns and oilfield brines. |
| Metallurgy & Corrosion Resistance | Standard SS304 or lower grade stainless steel; rapid pitting and stress corrosion cracking (SCC) under tropical chloride exposure. | Titanium Gr.2 / Hastelloy C-276 in boiling evaporators; high-temperature carbon steel lined with isostatic virgin PTFE (3-5mm) for all aggressive fluid circuits. |
| Climatic Thermal Balance | Atmospheric cooling basins assuming low ambient humidity (arid deserts like Atacama or Qinghai). | Forced internal closed-loop chilled cooling drums designed to counter the extreme 85%+ relative humidity of coastal La Guajira and Barranquilla. |

| Process Automation (HMI) | Basic push-button relays or non-localized English/Chinese PLC interfaces; minimal fault diagnostics. | Siemens / Allen-Bradley PLC platform with fully localized Spanish SCADA touchscreens, automated density logging, and remote IoT diagnostic support. |
Transforming low-density, contaminated raw brines into ultra-pure industrial flakes ($MgCl_2\cdot 6H_2O$) via automated, energy-optimized thermal transformations.
Removal of sulfate ($SO_4^{2-}$), calcium, and heavy metal impurities through controlled chemical precipitation. Brines pass through our high-efficiency PTFE-lined filtration batteries to protect downstream evaporators from scaling.
Thermal concentration utilizing Mechanical Vapor Recompression (MVR) or Multi-Effect Evaporators (MEE). Boiling brine concentration increases from 28-30° Bé up to supersaturated 42-45° Bé under tightly governed vacuum conditions.
Secondary high-density separation removes remaining sodium chloride ($NaCl$) and potassium fractions. The concentrated bischofite slurry enters adiabatic crystallization vessels with continuous torque monitoring.
Molten liquor is continuously fed onto an internally cooled, precision-ground stainless rotary flaking drum. Adjustable doctor blades harvest crisp flakes, which are fed through automated anti-caking bagging stations.
Operating evaporative chemical plants in high-altitude Colombian industrial zones (such as Bogotá or Tunja at 2,600+ meters) or humid coastal environments (such as Riohacha at sea level) requires radically differing thermal balances. Ruitu customizes evaporator pressure differentials, barometric condenser water flows, and boiler heat transfer coefficients to guarantee stable crystal yield regardless of atmospheric pressures.
Configuring magnesium chloride processing outputs to meet strict commercial purity grades demanded across key Colombian economic drivers.
Unpaved haul roads in the open-pit coal operations of Cesar and La Guajira suffer from extreme arid winds. High-purity magnesium chloride flakes manufactured with Ruitu systems produce natural, non-hazardous hygroscopic brine that absorbs ambient air moisture, compacting aggregate road surfaces and reducing road-watering frequency by up to 80%.
Exploration projects throughout the Llanos Basin (Rubiales, Castilla) intersect challenging shale formations. Clear, solids-free $MgCl_2$ completion fluids formulated from high-grade crystal products stabilize delicate downhole clays without risking polymer formation damage or casing corrosion.
The construction boom across Bogotá, Medellín, and Cali utilizes light-weight, fireproof magnesium oxychloride cement boards. Ruitu's precision flakers ensure exact hexahydrate stoichiometric ratios ($MgCl_2:MgO:H_2O$), preventing efflorescence and premature panel cracking.
Guaranteed adherence to statutory industrial safety, structural civil codes, and maritime logistical procedures for seamless commissioning across Colombia.
All motor control centers (MCC), variable frequency drives (VFDs), and instrumentation are assembled to conform with Colombia's Reglamento Técnico de Instalaciones Eléctricas (RETIE). Explosion-proof wiring conduits, dual-voltage transformers, and NEMA 4X / IP66 enclosures guarantee maximum electrical safety in humid, saline working zones.
Colombia sits along the active Ring of Fire. Process skids, crystallizer support towers, and large-scale extraction tanks are structurally verified using FEA simulations in accordance with the Reglamento Colombiano de Construcción Sismo Resistente (NSR-10), ensuring robust structural integrity during high-load operational events.
Extensive experience coordinating multimodal ocean logistics into Cartagena, Buenaventura, or Barranquilla. We supply complete bilingual technical files, HS classification support (DIAN regulations), and documentation formatted for capital goods tax exemptions within Colombian Free Trade Zones (Zonas Francas).
Salt-chemical processing plants are delicate thermodynamic ecosystems. Sourcing individual pieces of equipment from disparate vendors often results in mismatched heat capacities, premature pipe clogging, and disputed failure accountability. Ruitu delivers total EPC peace of mind:

Ultra-thick rotational polyolefin lining fused to steel shell, providing cost-effective raw brine and acid storage.
Heavy-duty mobile stacking conveyor with variable height adjustment for open-air salt stockyards and mining pads.
High-thermal-efficiency gas/biomass furnace supplying clean hot drying air for chemical crystal fluid beds.
Multi-deck classification screen linked with automated weighing and sealing bagging machines for refined salt grades.
End-to-end turnkey assembly including evaporators, crystallizers, cooling flakers, pumps, and central DCS automation.
Commercial and technical clarification for project developers, chemical plant directors, and procurement managers.
Our plants are custom designed around four primary Colombian feedstocks: 1) Sea salt bitterns (agua madre) from Caribbean solar operations like Manaure (typically entering at 28°–32° Baumé rich in magnesium sulfate and magnesium chloride); 2) Oilfield produced waters from the Llanos Basin containing calcium-magnesium chloride complexes; 3) Rock salt mother liquors from Zipaquirá and Nemocón processing; and 4) Acid-leached magnesite tailings. We formulate the pretreatment reaction balance specifically to eliminate sulfates via controlled calcium chloride titration before thermal concentration.
In many Colombian industrial zones, boiler fuel (natural gas or fuel oil) is either expensive or pipeline-restricted, whereas electrical power from Colombia's hydroelectric grid is comparatively abundant and stable. MVR recycles the latent heat of secondary vapor by compressing it through a mechanical turbofan compressor, slashing live steam consumption by up to 90% and reducing operating expenditure per ton of flake by 35% to 50% compared to traditional steam-heated systems.
Magnesium chloride is notoriously aggressive; at temperatures above 80°C, it causes rapid stress-corrosion cracking and severe pitting in standard 304 and 316L stainless steel. Ruitu utilizes a layered metallurgical architecture: all high-temperature evaporator tubes and crystallizer heating elements are fabricated from Titanium Gr.2 or Hastelloy C-276. For process piping, valves, separators, and storage tanks, we apply seamless isostatically molded virgin PTFE (polytetrafluoroethylene) or rotomolded PO linings backed by heavy carbon steel bodies, delivering indefinite corrosion lifespans at optimized capital cost.
Yes. In ambient environments with 85%+ relative humidity and 38°C temperatures, open-air crystallization fails because magnesium chloride is highly hygroscopic and absorbs moisture from the atmosphere. Ruitu flaking lines utilize fully enclosed, sealed stainless rotary drums with chilled internal water jackets, matched with climate-controlled, dehumidified packing enclosures to prevent flakes from caking or turning into slush during automated bagging.
Strictly compliant. We engineer our electrical cabinets to meet Colombian RETIE regulations, utilizing UL/CE-listed switchgear, Schneider or Siemens components, 60Hz 440V/220V power standards, proper galvanic grounding systems, and Spanish-language HMI interfaces. In hazardous operating environments near hydrocarbon extraction facilities, motors and field instruments are supplied with certified explosion-proof ratings.
A standard 10,000 to 50,000 ton/year turnkey magnesium chloride plant typically requires 14 to 18 weeks for detailed engineering, process simulation, and factory fabrication in Weifang; 4 to 5 weeks for maritime transit to Cartagena or Buenaventura; and 6 to 8 weeks on site for positioning, skid interconnecting, wiring, trial water testing, and operational commissioning under the direct supervision of Ruitu field engineers.
