Technical guides covering autoclave design, scale-up criteria, WFI systems design, and process safety barriers.
Biopharmaceutical and API facilities handle highly potent active pharmaceutical ingredients (HPAPIs). Exposure to even microgram quantities of these compounds can cause severe health issues for plant operators.
One of the leading causes of industrial process incidents is the failure of the Management of Change (MOC) process. Modifications to piping, software control logic, or operating conditions can introduce unforeseen hazards.
Traditionally, chemical plants manage process hazards by adding safety systems (PSVs, interlocks, dump tanks). However, these add-on barriers can fail. Inherently Safer Design (ISD) is a design philosophy that focuses on eliminating or minimizing hazards.
Avoid electrostatic ignitions during solvent transfers. Learn about charge generation, grounding/bonding requirements, relaxation times, and piping safety rules.
A comprehensive chemical engineering guide to industrial dust collection system design in API and specialty chemical plants. Details baghouse sizing, Air-to-Cloth (A/C) ratio, duct transport velocity, canister velocity, explosion venting (NFPA 68), filter media selection, and downloadable Excel calculator resource.
The US Occupational Safety and Health Administration (OSHA) enforces the Process Safety Management (PSM) standard to prevent catastrophic releases of highly hazardous chemicals (HHCs).
When physical relief devices (like PSVs) cannot handle runaway reactions or toxic releases, process designs rely on Safety Instrumented Systems (SIS). An SIS is an independent system of sensors, logic solvers, and final control elements (valves).
A comprehensive chemical engineering guide to building chemical compatibility charts and assessing reactive chemical hazards. Details the CCPS & NOAA Chemical Reactivity Worksheet (CRW) methodology, functional group incompatibility mechanisms (gas evolution, thermal runaway, polymerization), binary compatibility matrices, and a downloadable Excel calculator.

Conduct safety assessments for exothermic chemical reactions. Master reaction calorimetry (RC1), differential scanning calorimetry (DSC), Stoessel criticality indexes, and regulatory compliance.
Learn the step-by-step process of sizing pressure safety valves (PSVs) under API 520/521. Identify overpressure scenarios, calculate relieving rates, and determine orifice areas.
A comprehensive chemical engineering guide on transitioning from spreadsheet chaos to modern, open-standard digital HAZOP and LOPA workflows using minimal-setup tools like Kenexis Open-PHA. Covers P&ID node boundary isolation, cause-consequence linking, IPL credits, SIL target allocation, automated reporting, and 5-year OSHA PSM revalidations.
In pharmaceutical solid dose manufacturing, many raw materials, active pharmaceutical ingredients (APIs), and excipients are combustible organic powders. Operations like milling, sifting, blending, and tableting generate fine dust clouds.
A comprehensive, step-by-step HAZOP study guide for process engineers. Covers P&ID node boundary selection, guideword-parameter matrices, a 5x5 Risk Ranking Matrix, a complete 5,000 L batch reactor worksheet, and LOPA/SIL alignment.
An authoritative chemical engineering guide on managing runaway reaction risks during technology transfer in multipurpose pharma/API equipment, covering Arrhenius kinetics, Semenov TNR theory, Stoessel criticality, field instrumentation (2oo3 RTDs, Coriolis meters), cascade control loops, soft sensors, SIS / SIL-2 interlocks, and automated emergency quench systems.
