Chemical Synthesis

Mastering diverse reactions

Over the past decade, our team has successfully executed various chemical synthesis projects encompassing a wide range of reactions. Some of the key reactions we have worked on include:

  • Sulphonation (Using Sulphuric Acid, Oleum, Liquid SO3 at High Temp/Pressure and Low Temp/Pressure )
  • Caustic/Alkali Fusion (Very High Temperature, Pressure)
  • Carboxylation/Kolbe-Schmitt
  • Nitration (High Temperature, Pressure, Flow Chemistry)
  • ChloroSulphonation with SOCl2
  • Hydrogenation
  • Cyanation with Sodium Cyanide
  • Diazotisation
  • Oxidation/Reduction
  • Oxidative Cleavage
  • Chiral Chemistry
  • Hydrolysis
  • Alkylation
  • Acetylation/Acylation
  • Aldol Condensation
  • Sandmeyer Reaction
  • Butyl Lithium Reaction
  • Boron Chemistry
  • Halogenation
    • Fluorination (HF, KF, NaBF4, BF3/Catalytic
    • Fluorination
    • Bromination (HBr, Br, NaBr)
    • Chlorination (Cl2, HCl Liquid and Gas, SOCl2, etc.)
  • Amidation
  • Ammonolysis
  • Fries Rearrangement

Process Engineering

Maximizing efficiency, minimizing impact

Our approximately 25-member in-house Process Engineering & Technical Services Team, along with a small multi-disciplinary team of Civil, Electrical, Project and Mechanical Engineers, are led by senior Process Engineering experts with 30-plus years of experience. Most of the Basic Engineering functions are carried out in-house while Detailed Engineering (FEED) is often farmed out.

At Sustainable Sciences, we are all about optimizing resource utilization, minimizing waste generation, reducing capex and opex, and decreasing the overall ecological impact of industrial operations. By employing a combination of good innovative chemistries with efficient process engineering, we strive to design and implement processes that align with the principles of sustainability, with the lowest lifecycle costs.

Safety Studies

Mitigating hazards and promoting safe operations

Process safety is a fundamental aspect of our approach in every project we undertake. No project is initiated without the relevant groundwork. Our dedicated Process Safety team conducts thorough studies for each process, focusing on: Health and Environmental Hazards • Chemical Reaction Hazards • Process Safety Studies • Exothermic Reaction Studies • Fire and Explosion Hazards

Through these studies, we generate essential data that enables us to design and implement inherently safe processes, minimizing risks to personnel, the environment, and surrounding communities.

Environmental/ZLD Studies

Sustainable parameter control

Our waste pre-treatment studies focus on minimizing environmental impact during the Route Selection & Process Design stage. Our goal is to achieve Zero Liquid Discharge while keeping costs to a minimum. We target several environmentally significant parameters, including:

Chemical Oxygen Demand (COD) • Biochemical Oxygen Demand (BOD) • Total Suspended Solids (TSS) • pH levels • Total Dissolved Solids (TDS) • Ammoniacal Content

By addressing these parameters, we seek to reduce the environmental load and ensure sustainable waste management practices.
