Basic prerequisites are a thorough knowledge of chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of a process in a computing device. Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. The software has to solve the mass and energy balance to find a stable operating point. The goal of a process simulation is to find optimal conditions for a process.

Tauris Help is your AI troubleshooting assistant for HVAC, plumbing, and electrical equipment. Point your camera at the nameplate — or just type the model — and Tauris Help walks you through the fix so you can close the ticket and move on. Built for technicians, facilities staff, and anyone who has to keep equipment running, Tauris Help turns a confusing fault into a clear, step-by-step answer grounded in the actual service manual for your unit. WHAT YOU CAN DO • Snap the nameplate — identify the exact make and model from a photo. • Or type the model number, or describe what you're looking at. • Ask what's wrong and get a clear, step-by-step troubleshooting path. • Get answers grounded in the unit's service manual, not generic guesses. • Attach photos of what you're seeing in the field for better context. • Keep every session saved to your history so you can pick up where you left off. THREE STEPS. NO LEARNING CURVE. 1. Tell us the unit — snap the nameplate or type the model. 2. Describe the issue — type what's happening or send a photo. 3. Get your fix — clear, step-by-step answers fast enough to keep your day moving. WORKS ON THE EQUIPMENT YOU SERVICE HVAC systems, VRF/VRV units, chillers, rooftop units, plumbing, and electrical gear. If it has a nameplate, Tauris Help can help you identify it and work the problem.
