We design and build amine systems, distillation towers, multiphase separators, heat recovery, and gas treating equipment. Our products include vapor compression systems using refrigerants such as ammonia, CO2, propane, and others, absorption systems, or expansion of compressed gases.
Our amine sweetening units utilize liquid solvents to remove acid gases (CO2 and H2S) from natural gas. This regenerative solvent requires heat to release a concentrated stream of acid gas that can be further processed or reinjected. Based on the application, we can design the process to maximize CO2 slip or enhance CO2 removal.
With a variety of available solvents, Startec will provide the most economical sweetening solution for your project and business.
Our amine units are capable of 1 – 400 MMSCFD with rates ranging from 30 – over 1,600 GPM. Our amine is achievable of less than 4.0ppm H2S, and less than 2.0mol% CO2 outlet gas.
Solvent technologies include DEA, MDEA, DGA, Mixed Amines, Proprietary Amines, Sulfinol, and Selexol.
Fuel gas treatment for engines or turbines is a crucial process for optimizing efficiency and extending operating life.
Startec provides the correct treatment & filtration of gas to meet optimal fuel gas quality for your application needs, with capacities from 0.25 – 50 MMSCFD.
Startec provides a liquid desiccant T.E.G. system for the removal of water from natural gas to meet pipeline specifications.
Startec's standard sweet and sour designs range from 30 – 50 MMSCFD, capable of 1 – 400 MMSCFD with operating pressures of 150 – 1,400 PSIG. Startec offers custom designs as well.
Startec regularly manufactures E.G. dehydration systems as part of our mechanical refrigeration gas plants. Our standard E.G. packages range from 1.5 – 20.0 GPM, capable of 20 – 600 MMSCFD.
Startec's proven technology and meticulous design cut E.G. injection rates in half.
Startec's molecular sieve units provide maximum water removal from natural gas, allowing it to be processed at cryogenic temperatures (less than -100°F), with standard designs capable of 20 – 600 MMSCFD.
Refrigeration is a foundational product offering at Startec, ranging from 10 – 2,500+ tonnes, with natural gas plant capabilities from 1 – 400 MMSCFD. Known for our pioneering way, we continue to perfect cooling methods for a myriad of industries including natural gas processing, petrochemical, refining industrial gas, and others.
Startec packages Mycom, Howden and Ariel products for your rotary screw, reciprocating, or centrifugal application and are a proud OEM of Frick products.
Whether your challenge is small or large, you can trust Startec to find a better solution.
Startec's dew point control packages process natural gas for pipeline transmission. Either Joule Thomson or mechanical refrigeration applications do this by condensing out the heavier hydrocarbons from the gas and bring the quality of the natural gas to the project's pipeline specifications.
Our mechanical offerings use a refrigeration loop to cool natural gas, again dropping out the heavy hydrocarbons and ensuring gas meets the pipeline specifications.
These hydrocarbon liquid dropouts add another revenue stream for your business and create more value for your project.
Startec's dew point control designs are capable of 1 – 400 MMSCFD, with pressures ranging from 150 PSIG – 1,300 PSIG.
For maximum NGL recoveries, Startec has a variety of solutions to meet your needs including reciprocating, liquid ring, rotary, screw, and vane. We offer cold mechanical refrigeration (-40°C), a combined mechanical refrigeration and J.T. unit, and turbo expander deep cut packages. These packages are capable of 10 – 400 MMSCFD.
From production well condensate to pipeline condensate, Startec has an energy-efficient stabilizer design – capable of 250 – 60,000 bbl/day – that will process your liquids to meet pipeline C5+ specifications. Trouble with paraffinic condensate? Startec stabilizers are designed to reduce fouling through the elimination of wax precipitation.
Startec proudly offers standard fractionation designs for de-ethanizers, depropranizers, and debutanizers with fully customizable options to ensure your project can access various types of transportation. Specializing in modular designs, these units are capable of up to 120,000 bbl/day output, with all stacking completed in house.
Sour water must be expertly processed and sweetened in a sour water stripper to be disposed of or reused. Startec’s sour water strippers remove hydrogen sulfide and ammonia from sour water generated in industrial processes like fracking, refining, and more. Startec has the expertise and technology for your sour water treating needs with capabilities from 1,000 – 50,000 bbl/day.
Our client in Pakistan required a propane refrigeration plant to mechanically cool the natural gas temperature of 48MMSCFD from 30F to -10F.
After providing equipment for the first two phases, our client trusted Startec to design an optimized expansion of their third phase.
Because real solutions to our clients’ needs do not come prepackaged, working closely with the engineering and design team through the bid process and onward, Startec’s Everyday Mavericks used our proven standardized building blocks to provide cost-effective designs while modifying packages to meet the client’s unique specifications and operational requirements.
Regularly having problems with an existing plants’ stabilizer, our client made Startec their partner of choice when they decided to expand their facility and solve a few legacy problems so they could reach full production capacity.
Startec fully designed and fabricated this packaged stabilization skid complete with standalone tower.
Startec fully designed and fabricated a packaged stabilization skid complete with standalone tower. This design included a split feed to the stabilization tower for improved heat recovery, control options, and reduction in energy required for the condensate product.
Challenging ourselves to find a better way, Startec was able to provide a much larger mechanical refrigeration unit than the previous phase. This was achieved while still maintaining the client's approved major equipment manufacturers, even though the first phase was built by another packager.
Always searching for a better way, the Startec team provided an innovative design, which removes much of the water that is entrained in the gas due to sour processing by the amine plant. This design provided lower propane chiller and Ethylene Glycol injection duties, which offers significant savings on capital and operational expenses.
When Startec first became involved, the project was behind schedule and without a selected engineering company. In short order, we completed a process simulation for the entire facility from inlet separator through to sales. Working with the EPC, Startec was involved in the detailed design beyond our scope. Following an aggressive timeline, all expected delivery dates were successfully met or exceeded. Total change orders were less than 1.5% of the original contract value.
