Efficient Electric Heat Tracing: Energy Assurance for Panjin Sanli Zhongke New Materials' Annual 100,000-Ton Production Project
Project Background The Panjin Sanli Zhongke New Materials Co., Ltd. has launched an industrial project for the annual production of 100,000 tons of new materials, located in the western expansion area of the Panjin Fine Chemicals Industry Development Zone. This project is a successful transformation of technological achievements from their pilot base into full industrialization. The total investment for the project is 2.1 billion RMB, with the first phase investment amounting to 1.1 billion RMB and occupying an area of 269 acres. It primarily utilizes the ethylene three-step method for MMA production, a technology co-developed with the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and the Department of Chemical Engineering at Tsinghua University. This technology resolves key challenges in oxidation and esterification processes, representing a unique advantage in achieving an internationally advanced level and being the first of its kind in China.Project Solution The project is located in Panjin, northeastern China, characterized by a temperate continental semi-humid monsoon climate. The region experiences spring droughts, hot and rainy summers, rapid temperature drop during autumn, and cold, dry winters, with historical extreme minimum temperatures reaching -30.6°C and maximum wind speeds up to 21 m/s. Additionally, there is a possibility of salt fog corrosion on-site. Taking into account the physical and chemical properties, process temperatures, and heat loss of different pipeline connections and diameters for various process media (such as acetic acid, concentrated sulfuric acid, laboratory wastewater, domestic water, firewater, NaOH, etc.), ZTC Technology (Suzhou) Co., Ltd. uses a specialized electric heat tracing modeling system. This system simulates the actual heat dissipation and absorption processes on-site to effectively match the heat tracing system and accurately divide circuits. Coupled with a precise temperature monitoring system, it ensures temperature maintenance, process temperature, and current setpoint are displayed on an LCD/LED screen. The control module provides information on "temperature, heating current, ground leakage current, maximum and minimum temperature storage" for each circuit and delivers alarm signals such as low and high temperature, heater low/high current, ground leakage current, and RTD sensor fault alarms. It is equipped with a self-testing function, periodically energizing all heaters and can be programmed via a keyboard.To avoid resource waste in power supply and control due to the large plant area and scattered installations, this solution establishes independent power and control platforms for various units. These include the gasification unit, syngas purification unit, n-propionaldehyde unit, formaldehyde unit, MMA unit, ethylene tank group, chemical tank groups (one and two), formaldehyde tank group, acid and alkali tank group, vehicle loading and unloading facilities, exhaust gas incineration units, rainwater storage tank and emergency water pool, initial rainwater pool and production wastewater pools (one and two), domestic wastewater pool (one), laboratory wastewater pool, and the entire plant's electrical system. By utilizing distributed power supply and control systems, the scattered heat tracing circuits are consolidated into an energy-efficient, environmentally friendly, and safe intelligent electric heat tracing system. This achieves thermal balance in process pipelines, normal flow of process media, and stable operation of installation areas.For service inquiries, contact: 4008288613

ZTC Electric Heat Tracing System: A Warm Barrier for Data Security
Engineering Cases Renovation of the Chiller Room at Jiangnan Rural Commercial Bank Data Backup Center With the rapid development of the information age, the expansion of data center scales, and the continuous improvement of computing density, the importance of their cooling systems is increasingly prominent. However, in the winter season, the issue of preventing frost in the cooling tower pipelines of data centers is becoming more apparent. To ensure the continuous and efficient operation of data centers in low-temperature environments, an appropriate heat tracing and antifreeze system solution serves as a warm defense line safeguarding data security. Renovation Project for the Computer Room at Ningbo Bank Bizhou Building Due to the requirement for the cooling tower in the computer room to operate year-round, implementing effective electric heat tracing measures to prevent freezing can ensure the smooth transport of cooling water, firefighting water, and drainage from the roof, ensuring the continuous and stable operation of the data center. The electric heat tracing system carefully designed by the ZTC technical team can precisely control the pipeline temperature, which is a key measure to ensure the normal operation of water-cooled units in low-temperature environments. For the Ningbo Bank Bizhou Building project, ZTC Technology provided comprehensive professional services from pre-sale consulting, design, installation, and technical guidance to maintenance, thereby offering strong support for the stable operation of the Ningbo Bank Bizhou Building data center.

Empowering with Heat, Advancing with Warmth - Yulong Island 40 Million Tons Per Year Refining and Chemical Integration Project
Project BackgroundThe 40 million tons per year Yulong Island Refining and Chemical Integration Project is a major project for promoting high-quality development and transitioning of old and new driving forces in Shandong Province.The seawater desalination project of the Yulong Island Refining and Chemical Integration project is implemented in two phases under a general plan. The first phase proposes to construct a crude oil processing capability of 20 million tons per year and an ethylene unit of 3 million tons per year. It mainly constructs a series of refining processing devices, such as a 10 million tons per year atmospheric distillation device and a 10 million tons per year reduced pressure distillation device, as well as several sets of advanced chemical process devices. The project fully excavates the stepwise reutilization of low temperature waste heat resources in the Yulong chemical system, combined with green, low-carbon, thermal film-coupled F-MED-RO new process and dual-membrane full-process technology.Solution01 The uniqueness of heat tracing in Seawater DesalinationIn the seawater desalination system, the low temperature of seawater and its high salt content can easily cause condensation or freezing on the surface of pipelines and equipment, thus affecting the normal operation of the system and the service life of the equipment.
