Esenar understands the technical, cGMP and regulatory challenges required for Pharma & biopharmaceuticals. Our objective is to deliver innovative and functional process engineering and systems engineering solutions for your complex projects by taking responsibility for specification, procurement, design and build, and commissioning and validation

Below are the Capabilities of a Process Engineering Team.

Conceptual Design:

Block Flow Diagrams, Process Model and Basic Utility Calculations

Basic Design:

PFD development, Equipment Layout arrangement, CIP, SIP, Process flowpaths and Valve Matrix

Detailed Design:

Interface Automation Matrix, Function Specifications or Operational Description, Equipment sizing calculations, Pressure Drop Calculations, Vendor document reviews

PW, WFI & Pure Steam Design:

Esenar fully understands the requirements of Purified Water, WFI & Pure Steam with multiple industries from initial design and installation, including IQ/OQ/PQ

CIP & SIP Skid Design:

Cleaning & sanitization process for process vessels and interconnecting process piping is one of the most critical process in the Pharmaceutical, Life sciences, Healthcare and Cosmetic to remove residues from the previous batches and ensure contamination-free systems. Esenar designs the skids as per the ISPE,ASME BPE and GMP guidelines

Piping Design Engineers play a vital role in development or re-construction of Plants, related to Oil & Gas Industries, Power Plant, Fertilizers Industries and Food Industries etc

The plant engineering and design industry is gradually evolving and incorporating the latest technological advancements in planning, designing, modifying, installing and maintaining various plant facilities, systems, equipment etc

Plant Design services are especially useful while designing mechanical, structural, instrumental, and piping designs. Our Esenar team will design plant by following Regulations and guidelines like ASME BPE, ISPE,ASME Section 8 Div II and ASME B31.3
