Field-tested knowledge on environmental engineering, lithium battery manufacturing, plant design and compliance — written for engineers who build the clean economy.
Every environmental permit comes with monitoring requirements. Every monitoring requirement generates data. And every data gap during an inspection becomes a potential violation.…
Every process plant needs cooling water. Yet cooling system design is one of the most frequently underestimated disciplines in plant engineering. Undersized towers, fouled…
The EU Battery Regulation isn't coming — it's here. By August 2025, every battery placed on the EU market needs a carbon footprint declaration. By February 2027, a full Battery…
China's Soil Pollution Prevention and Control Law (土壤污染防治法, effective January 2019) introduced mandatory self-monitoring and reporting obligations for "key soil pollution…
Choosing the wrong plant design software costs more than license fees. It costs rework, schedule delays, and — in the worst case — a 3D model that nobody trusts. I've used all…
Distillation is the workhorse of chemical separation — and the single biggest energy consumer in most process plants. A poorly designed column costs you in three ways: excessive…
I've designed tank farms for chemical plants, refineries, and battery factories. The principles are the same across industries, but the consequences of getting them wrong vary…
A pressure safety valve (PSV) is the last line of defense between normal operation and catastrophic failure. When everything else fails — the control system, the operator…
After 13 years in process engineering, I've participated in over 50 HAZOP studies. I've seen HAZOPs that caught near-misses before they became incidents, and HAZOPs that were…
Every industrial facility uses chemicals. Every chemical comes with a Safety Data Sheet (SDS). And in my experience, most facilities have a binder full of SDSs that nobody reads…
China's Environmental Impact Assessment (EIA) system categorizes every construction project into one of three tiers: EIA Report (环境影响报告书), EIA Form (环境影响报告表), or Registration…
The pipe isometric (iso) is the one drawing that follows a pipe from engineering office to fabrication shop to construction site. It's not just a picture — it's a bill of…
