2 World-renowned experts in mass transfer technology GTC Technology's Since 1994, GTC has provided specialized process equipment technology Process Equipment Solutions that cover a broad spectrum of conventional and proprietary mass Technology transfer equipment designs for trays, packing and other Tower internals. All of our division offers trays are designed to achieve optimum capacity and efficiency and our technology an extensive line applies fundamental principles such as liquid gradient elimination, static head of equipment and control, plug flow optimization, vapor dispersion injectors, optimum vapor-liquid services that can distribution, liquid flux management and anti-fouling capabilities.

3 Be customized to At GTC, we work with each client to customize our extensive line of mass transfer provide complete technology trays for different process conditions from high pressure to vacuum mass transfer conditions, fouling, polymerization, and chemical reaction. We offer a wide Solutions to our variety of active devices including floating or fixed valves, rectangular or round, clients and to sieve, bubble caps, and shed decks among others. Our world-recognized process the market. engineers combine process solution with extensive equipment knowledge to maximize revamp opportunities, increase column efficiency and reduce energy consumption. page 1.

4 GTC Technology Engineered to Innovate Advanced distillation column design Revamping distillation columns requires a solid process design background, partic- After ularly when conducting evaluations of existing equipment and data. GTC advises debottlenecking clients to understand where they are on the reflux to theoretical stage curve prior to with GTC's high setting the design strategy for a column. The lower the stage count, the higher the Performance reflux rate required. However, the exact sensitivity will affect considerations in the trays, our revamp and design of your distillation Tower . For each distillation column revamp column's design , GTC conducts dedicated sensitivity analysis to optimize the column pressure drop Performance among capacity, efficiency and energy consumption requirements.

As a result, GTC has helped Reflux Ratio (vol).

Our trays deliver Performance improvement through: Lower entrainment Less weepage Higher efficiency Greater through-put Higher turndown Wide range of operating regimes Low fouling, anti-fouling page 5. GTC Technology Engineered to Innovate Downcomer Area Downcomer Area GT-OPTIM high Performance Trays Most conventional trays will not perform a plug flow operation, resulting in variable liquid residence time and decreased tray efficiency. In addition, high residence time on selected areas of the active panel can encourage fouling. Inlet Inlet GT-OPTIM trays are designed to achieve a plug flow effect across the active panel, increasing efficiency and fouling resistance.
