Frequently Asked Questions (FAQ) About Modular Hydrotreater Plants
Crystal Industrial’s Modular Hydrotreater Plants
1. What is a modular hydrotreater plant?
A modular hydrotreater plant is a compact, factory-built system designed to remove contaminants like sulfur, nitrogen, and metals from various petroleum or renewable feedstocks. Built on skids, these modules are pre-assembled, pre-tested, and ready for rapid deployment and integration on site.
2. What are the key advantages of modular hydrotreater plants?
Modular plants offer faster deployment, reduced on-site labor, minimized civil work, scalability, and improved quality control. They are ideal for remote locations, pilot projects, and phased capacity expansions.
3. What feedstocks can Crystal Industrial’s hydrotreaters process?
Our modules can process diesel, naphtha, kerosene/jet fuel, tail gas, and specialty feedstocks like used cooking oil (UCO), tallow, and base oils. Custom configurations are available for unique requirements.
4. What capacity ranges do Crystal’s modular units support?
Our modular hydrotreater plants are designed for capacities from 500 barrels per day (BPD) up to 20,000 BPD, with parallel modularization enabling scalable installations.
5. Are Crystal Industrial’s plants compliant with international fuel regulations?
Yes. Our plants meet or exceed compliance standards such as Euro V/VI, IMO 2020, US EPA Tier 3, and Bharat Stage VI (BS-VI). Aviation fuel units comply with ASTM D1655 and DEF STAN 91-91.
6. What industries commonly use these modular plants?
Industries include petroleum refining, biofuel production, gas-to-liquids (GTL), marine fuel supply, aviation, specialty chemicals, and military/remote energy operations.
7. Can these modules be customized for specific feedstocks or locations?
Absolutely. We offer full customization based on feedstock properties, throughput, site constraints, and downstream integration needs. Our engineering team works closely with clients to deliver tailored solutions.
8. How long does it take to deliver and install a modular hydrotreater plant?
Typical project timelines range from 6 to 10 months from design to delivery, depending on complexity and capacity. Installation and commissioning on site take 2 to 4 weeks, significantly faster than stick-built alternatives.
9. What automation systems are used in your modular plants?
Our systems support DCS or PLC-based control, with features like remote monitoring, smart instrumentation, alarm management, and secure network architecture. We integrate with client-preferred automation brands or provide turnkey controls.
10. What are the utility requirements for operating a modular hydrotreater plant?
Utilities include steam, cooling water, instrument air, and electric power. Each module is designed for efficient utility consumption and is supplied with a detailed utility interface document for easy site integration.
11. What fabrication standards and codes do you follow?
Crystal Industrial complies with international codes such as ASME Section VIII, API 650/661/560, ANSI/ASME B31.3, NACE MR0175, and ISO 9001:2015. We offer CE/PED certifications upon request.
12. What testing and quality checks are performed before shipment?
All modules undergo hydrotesting, radiographic and ultrasonic weld testing, instrument calibration, electrical continuity checks, and a Factory Acceptance Test (FAT). Documentation and certifications are provided with every shipment.
13. What are the site preparation requirements for installing your modules?
Minimal civil work is required. Most modules can be installed on simple concrete foundations with anchor bolts. This reduces site disruption and civil costs by up to 60% compared to conventional builds.
14. Do you provide commissioning and after-sales support?
Yes. We offer full support during installation, commissioning, and performance trials. Our after-sales services include spare parts, maintenance training, troubleshooting, and technical upgrades.
15. Can Crystal Industrial export modular hydrotreater plants internationally?
Yes. We have extensive experience exporting to the Middle East, Africa, Southeast Asia, and Latin America. All skids are designed for road, sea, or containerized transport, with global documentation and packaging support.
