After Sales Support

After-sales support is a key division of project companies from the user’s point of view, whether during the warranty period or beyond.

This may relate to product or entire system supplied as package under project supply.

However, even if the supplied system or product is good, it becomes a failure if not supported promptly by the supplier.

We at DVC take every care, and it is our priority and practice to support the users of the product / system

Technical Audit of Existing Process Plant & Upgradation

We offer comprehensive technical audit services for Oil and Oleochemical processing plants, supplied & executed by DVC as well as other suppliers!

Technical audit of processing plants, followed by updates on the technological front as well as efficiency improvements, is the core strength of DVC. This is possible due to in depth knowledge of the subject and capability to handle complexities involved. Also, the feel of supporting the troubled users is prime motivation factor.

Our team comprises experienced process, mechanical, and instrumentation engineers. The audit is designed to evaluate overall plant performance, identify inefficiencies, and establish a clear roadmap for optimization.

A detailed technical audit report is issued outlining recommendations. Action plans are developed jointly with plant stakeholders, focusing on capacity enhancement, yield improvement, energy optimization, and operational reliability.

Process Performance Evaluation

Assessment of operating parameters across all processing sections, with benchmarking against design and industry standards.

Mass & Energy Balance Analysis

Detailed analysis to quantify losses, utility consumption (steam, power, thermic fluid), and opportunities for energy integration and recovery.

Equipment Health & Capability Review

Inspection of key equipment such as reactors, heat exchangers, separators, vacuum systems, deodorization and distillation columns to evaluate condition, capacity utilization, and performance limitations.

Bottleneck Identification & Debottlenecking Opportunities

Identification of constraints limiting throughput, efficiency, or reliability.

Instrumentation & Control Systems Assessment

Review of field instrumentation, control loops, automation logic, and interlocks to ensure measurement accuracy, process stability, and safe operation.

Product Quality & Yield Analysis

Evaluation of refining losses, FFA removal efficiency, oil recovery, and final product specifications.

Process Plant Modification & Optimization

Based on audit findings, we undertake engineering, design, and implementation of plant modifications and upgrades to achieve measurable performance improvements. All modifications are validated through performance guarantee runs, demonstrating improvements in throughput, reduced specific consumption, minimized refining losses, and consistent product quality.
  • Process Optimization & Revamp Engineering: Redesign of process sections to improve efficiency, reduce losses, and enhance flexibility for handling multiple feedstocks.
  • Equipment Upgrades & Retrofits: Replacement or modification of critical equipment (e.g., heat exchangers, bleaching systems, deodorization units, vacuum systems) to improve performance and reliability.
  • Instrumentation & Automation Upgrades: Modernization of control systems, advanced instrumentation, and automation strategies for improved process control and reduced operator dependency.
  • Energy Efficiency Improvements: Integration of heat recovery systems, optimized utility usage, and reduction in specific energy consumption.
  • Capacity Expansion & Debottlenecking: Targeted modifications to increase plant throughput with minimal capital investment.
  • Implementation & Commissioning Support: End-to-end execution including detailed engineering, procurement, site implementation, and commissioning.
